SingTel Deploys MPLS-TP for Global Carrier Ethernet Service

SingTel has deployed Multiprotocol Label Switching-Transport Profile (MPLS-TP) as the foundation for its ConnectPlus E-Line service, which provides up to 10 Gbps of Ethernet connectivity for multinational corporations.

SingTel is using the Cisco MPLS Transport Profile (MPLS-TP) suite of Carrier Packet Transport technologies for this global deployment.

SingTel is also planning to introduce dedicated point-to-multipoint and electronic Bandwidth-On-Demand (eBOD) for ConnectPlus E-Line services over the coming year

Cisco said its Carrier Packet Transport solution provides SingTel with a network that unifies both packet and transport domains, while providing a greater degree of freedom in terms of network topology demands regardless of its customers' locations, traffic conditions and bandwidth requirements.  SingTel is one of industry's first standards-based MPLS-TP deployments.
MPLS-TP also brings predictable resiliency and simplicity to service provisioning.

"The video, cloud, and mobile services are defining new meshed traffic patterns and placing unprecedented demands on the transport network architecture.  In deploying the Cisco Carrier Packet Transport solution, SingTel is able to simplify service fulfilment complexity and evolve the ConnectPlus suite of services into a new generation converged transport architecture ready for enabling future services," stated Jeff White, Vice President for Cisco's Service Provider Business in Asia Pacific, Japan and China.

SingTel's ConnectPlus E-Line Service Rides Global ASON + MPLS-TP Backbone

Singapore Telecommunications (SingTel) launched its ConnectPlus suite of global connectivity services, linking key business hubs in Asia, Europe and USA at rates up to 10 Gbps.

SingTel’s ConnectPlus International Private Leased Circuit (IPLC) and Ethernet Line (E-Line) services are delivered over SingTel’s meshed network of extensive submarine cable assets using Automatically Switching Optical Network (ASON) and the Multi-Protocol Label Switching – Transport Profile (MPLS-TP).

The intelligent optical network is able to detect faults swiftly and automatically switch data traffic to backup routes within 50 milliseconds.

SingTel noted that it is the first service provider in Asia Pacific to deploy MPLS - TP globally. This allows enterprises to increase their bandwidth by increments of 1Mbps, thereby offering them more cost-effective connections. Next year, SingTel will leverage this platform to deliver dedicated point-to-multipoint and electronic Bandwidth-On-Demand (eBOD) for E-Line services.

Demystifying SDN for Carrier Ethernet Networks

by Sandy Orlando,  
     
8/6/2012

Software Defined Networking (SDN) is the hottest new technology in networking. Google is running its backbone network traffic on an SDN network built using OpenFlow. Nicira was acquired by VMware for $1.26 billion to accelerate the adoption of network virtualization in the data center. Yet with all the buzz about SDN, it is not clear how it will be deployed in service provider networks and what it means to the expansion of Carrier Ethernet. 



Tsunami of data driving change


SDN and Carrier Ethernet are not mutually exclusive technologies. What’s more, both technologies help address the growing tsunami of data driven by the growth in mobile phones and tablets, the emergence of BIG DATA, and the rise in machine-to-machine communications.
Not only is the amount of data exploding, but the characteristics of that traffic are changing with over 70 percent of network traffic on mobile networks streaming media. As service providers roll-out new network services, they struggle with how to keep pace with growing consumer and business demand and how to grow their Average Revenue per User (ARPU) faster than costs. The growing appetite for new services as well as the pace of rolling out new services every three to six months is straining service provider networks.

In comes Carrier Ethernet and SDN

There is no secret why Carrier Ethernet is a $25 billion dollar business, expected to grow to over $47 billion by 2015. Carrier Ethernet offers significant cost advantages for service providers providing WAN transport for a wide-range of services, including mobile backhaul. With Carrier Ethernet, service providers can provide high-value-per-bit at a lower-cost-per-bit while maintaining the reliability and predictable performance required by even the most latency-sensitive applications.

The next stage of Carrier Ethernet growth will come from cloud services and Carrier Ethernet interconnects, combined with virtualized network services. The cost advantages of Ethernet alone cannot keep pace with the uncontrollable demand for bandwidth combined with the emergence of on-demand network services. The next generation of Carrier Ethernet solutions will need a new approach to network equipment design and architecture provided by SDN.

SDN fundamentals

Software Defined Networking is a new approach to architecting networking equipment that fundamentally changes the way we design and build networks in a data center and over a wide-area network (WAN). SDN moves from the monolithic network equipment design based on custom silicon, a custom control plane, and tightly integrated network applications (services) to a modular, programmable, and distributed design (figure 1).


Figure 1: Network architecture transformation.
 
The key to SDN is the decoupling of network control from traffic forwarding. This migration to a separate software-based controller offers a number of key advantages:
  • Programmability
  • Network application (service) abstraction
  • Global network view
Whether these controllers are based on the emerging OpenFlow standard or a hybrid of legacy switching/routing alongside OpenFlow, the network intelligence is centralized and appears to applications and policy engines as a single logical switch, which simplifies network design and operations.

Distributed traffic forwarders can be added as demand dictates, reducing costly oversubscription of network bandwidth. Moreover, the separation of the network services enables service providers to more quickly add new services without having to forklift networking devices.

The role of OpenFlow

OpenFlow is a communications interface between the control and forwarding layers in an SDN architecture. It allows direct access to and manipulation of the forwarding plane of physical and virtual network devices. The OpenFlow standard is developed by the Open Networking Foundation which was launched in 2011 by Duetsche Telecom, Facebook, Google, Microsoft, Verizon, and Yahoo.

The current version of OpenFlow (version 1.3) provides an instruction set for networks analogous to the x86 instruction set for PCs. The Open Flow (figure 2) protocol includes flow tables (generic primitives) that sit on top of (virtual) switch Ternary Content Addressable Memory (TCAM) and can perform the following actions:
  • Switching and routing
  • Firewalling
  • Switching non-OpenFlow logic locally
  • Sending to controller for processing


Figure 2: OpenFlow, courtesy of Open Networking Foundation, 2012

Other SDN standards and research

In addition to OpenFlow, there are several other standards and research activities for SDN, including:
  • Open Networking Foundation: Hybrid programmable forwarding planes
  • ITEF:
    • MPLS-TP Pseudowire configuration using OpenFlow 1.3 (draft-medved-pwe3-of-config-00)
    • SDNi: A Message Exchange Protocol for Software Defined Networks (SDNS) across Multiple Domains (draft-yin-sdn-sdni-00.txt)
    • Use Cases for ALTO with Software Defined Networks (draft-xie-alto-sdn-use-cases-01.txt)
  • MEF: is working on cloud-computing and SDN standards
See the ONF and IETF websites for full list of SDN standards.

SDN is important for the future of Carrier Ethernet

Software Defined Networking is important for the evolution of Carrier Ethernet. It provides a new mechanism for architecting networking equipment and network designs. Moreover, implementing SDN does not necessarily require a rip and replace strategy. Service providers and network equipment vendors can begin identifying the high-value use cases to take advantage of the flexibility and programmability of SDN. These can include:

  • Dynamically partitioning access points and cell radios on demand based on a number of different parameters, including carrier, usage, identity, device type at the mobile edge, enabling optimal use of spectrum, Wi-Fi, and Carrier Ethernet mobile backhaul links.
  • Pooled compute and storage across geographically distributed data centers, connected with Carrier Ethernet transport using SDN, which will carve out bandwidth and allocate optimal use of bandwidth.
  • Traffic steering for content management and distribution, providing granular routing of traffic based on a wide-range of parameters such as subscriber policy, application type, and cache asset.

Waves of adoption

SDN is in its infancy and we have seen the first waves of adoption washing over the data center. For service providers and Carrier Ethernet equipment manufacturers, now is the time to begin researching SDN and identifying use cases that will drive future business.

While the ITEF and the MEF are beginning to explore SDN, the best place to learn about the technology is the Open Networking Foundation: https://www.opennetworking.org/. The ONF is the standards body for SDN and OpenFlow, and has tutorials and the OpenFlow specifications. In addition, the proceedings from the Open Networking Summit from April 2012 are online at http://opennetsummit.org/. There are a number sessions from service providers and vendors on SDN for carrier networks.

As the tsunami of data grows, the emergence of SDN in carrier networks is inevitable. Only a fundamental change in how we architect networks can prepare us for the dynamic growth in communications in the coming decades. Carrier Ethernet will continue to grow. As network equipment providers adopt SDN architectures, service providers will see more opportunities to accelerate new and profitable network services.

Infonetics: Carriers Like 100GE, MPLS, SDN, But Not So Much 40G

A new Infonetics survey of global carriers on their SDN, 40G/100G, and MPLS Control Plane Strategies finds a strong interest in software-defined networking (SDN) to simplify network provisioning.


"The networking industry is riding up the hockey stick curve of hype based on the hopes of new software-defined network (SDN)/programmable network technologies,” notes Michael Howard, co-founder and principal analyst for carrier networks at Infonetics Research. "And while many uncertainties surround SDNs due to their newness, our survey confirms that the programmable network movement is real, with a good majority of service providers worldwide considering or planning purchases of SDN technologies to simplify network provisioning and to create services and virtual networks in ways not previously possible."

Some highlights:


  • OpenFlow is the most developed programmable network initiative, and 80% of survey respondents are including it in their purchase considerations
  • 95% of service providers surveyed plan to deploy 100GE interfaces; most will not use 40GE
  • IP/MPLS (with control plane) is much more popular than MPLS-TP among surveyed service providers.

NSN Outlines "Liquid Net" for Fluid Capacity Network Dynamics

Nokia Siemens Networks outlined its "Liquid Net" vision for transforming radio, core and transport networks to fluidly adapt to fluctuating traffic demands. The goal of Liquid Net is to make new and existing carrier networks more self-aware and self-adapting, thereby unleashing frozen network capacity and directing it to where it is needed. The interlinked architecture calls for the use of software defined, multipurpose hardware and builds on the principles of the Liquid Radio architecture that was introduced by Nokia Siemens Networks earlier this year.


Liquid Net encompasses three domains:


Liquid Radio -- dynamically directing mobile broadband capacity to where it is needed most. It comprises three key elements: Baseband pooling for centralizing the processing requirement for dozens or even a hundred cells using smart scheduling algorithms; Active Antennas that integrate various radio frequency components into the antenna housing to enable advanced beamforming, allowing up to 65% capacity gain; and Unified Heterogeneous Networks, which offer automated management, seamless interworking and Quality of Experience across layers, cell sizes, and radio access technologies.


Liquid Core -- enables virtualization across the enhanced packet core (circuit-switched, packet-switched and IP Multimedia Subsystem), including elements such as the MSS, MGCF, CSCF and GGSN. Virtualization decouples the hardware from the software, freeing packet core functionality that previously required a separate network appliance and allowing it to now run on off-the-shelf ATCA hardware in a cloud-scalable manner. In addition, the Liquid Core ensures end-to-end Quality of service for content delivery by applying CDN caching, adaptation and optimization techniques.


Liquid Transport -- delivers the benefits of packet + optical layer integration. NSN is leveraging several innovations, including software configurable WDM optics, OTN for sub-lambda grooming and switching, and next generation optical access technologies. It is also putting in place an intelligent control plane using MPLS-TP and GMPLS.


Nokia Siemens Networks said its strategy is to continue to work in a multi-vendor approach with strategic partners.


Liquid Net's dynamic resource adaptation promises substantial capital and operational efficiencies. The company calculates that a truly "Liquid" resource allocation can unleash up to 80% of unused baseband capacity in the RAN and up to 65% capacity gain in individual cells; up to 80% footprint reduction in the packet core with 65% lower energy consumption; and up to 60% total cost reduction for the transport backbone.


"Capacity in today's conventional networks is typically frozen in separate places; at individual base station sites, in parts of the core network that manage voice and data services, or in the optical and IP transport networks," said Marc Rouanne, head of Network Systems at Nokia Siemens Networks. "Each is a potential bottleneck to someone getting the broadband service they want at a particular moment. Fluctuating, unpredictable demand in one part of the network means huge chunks of capacity can be left idle elsewhere, making poor use of existing investments. For example, as much as 50% of a conventional core network's capacity can be dormant. Instead, Liquid Net unleashes frozen network capacity into a reservoir of resources that can flow to fulfill unpredictable demand, wherever and whenever people use broadband."

  • In March 2011, Nokia Siemens Networks unveiled its new "Liquid Radio" mobile network architecture for dynamically directing mobile broadband capacity to where it is needed most. Baseband pooling is at the heart of the approach.



    Liquid Radio promises a more economic use of network resources through sharing and redistributing capacity based on user demand. Nokia Siemens Networks said its baseband pooling approach centralizes the resources needed to undertake processing functions common to every base station in a given area. Baseband pooling helps to achieve a more cost efficient sharing of resources over a large geographical area.


    Liquid Radio architecture comprises three key elements:


    Baseband pooling achieved via Nokia Siemens Networks‘ recently launched Flexi Multiradio 10 Base Station enables centralized pools of over 10 Gbps baseband capacity to manage up to 100 cells dynamically via smart scheduling algorithms.


    A new Flexi Multiradio Antenna System that provides true active antennas and complements the company's Flexi Multiradio Base Station family. The Flexi Multiradio Antenna System is based on several distributed radio frequency components integrated in the antenna housing to genuinely cooperate as a single entity to enable advanced features like beamforming. Beamforming provides additional capacity exactly where it is needed, allowing up to 65% capacity gain. Commercial availability is expected at the end of 2011.


  • Unified heterogeneous networks enable various network layers to be used as a logically unified network with automated management, seamless interworking and uncompromised quality of experience to the user. As modern mobile networks continue to carry most of the traffic for mobile broadband in the future, they are getting more complex with several bands and mobile technologies (like LTE, HSPA+, Long Term HSPA Evolution) and the use of smaller cells like micro, pico and femtocells. Also, alternative technologies like 802.1x WiFi are increasingly being used for mobile broadband capacity enhancement as well as the more traditional in-building coverage.
  • In February 2011, Nokia Siemens Networks unveiled its "Single RAN Advanced" architecture for supporting the full range of air interface technologies from GSM up through LTE-Advanced using software defined radios.


    Key components of Single RAN Advanced include a new highly powerful, compact and scalable Flexi Multiradio 10 Base Station. This base station will be 10 Gbps capable for high capacity cell sites. Single RAN Advanced also includes the Flexi Lite Base Station for micro and pico deployments, which are ideal for providing hotspot coverage in high traffic areas, and a Multicontroller platform for GSM and 3G.


    Nokia Siemens Networks Flexi Base Station will also have the capability to reallocate radio frequencies for maximum efficiency. The 4.2 MHz technology can rapidly refarm HSPA to lower frequencies with less spectrum required. It also offers spectral efficiency features like Orthogonal Sub Channel in GSM.


    Flexi BTS will also come with integrated IP transport interfaces. Flexi BTS will also feature a modular design and the ability to deployed outdoors, eliminating the need for shelter or huts with air conditioning.

Fujitsu: Ethernet Tag Switching Achieves 32% Percent Lower OpEx Than MPLS-TP

Fujitsu's implementation of Connection-Oriented Ethernet (COE), called Ethernet Tag Switching, reduces service providers' annual operating expenses by 32 percent over five years when compared to an MPLS-TP implementation, according to a research report by Network Strategy Partners (now part of ACG Research) cited by the company.


Fujitsu said its Connection-Oriented Ethernet enables a single metro network infrastructure with all the flexibility and cost benefits associated with Ethernet, while providing the performance, quality-of-service and security previously only available via SONET/SDH.


The study by Network Strategy Partners calculated the impact of using Ethernet Tag Switching, and then MPLS-TP, across six categories of service provider operations: OSS System Integration and Software Expenses, Network Management Equipment and Software, Training, Testing and Certification Operations, Network Care and Network Upgrades and Patches. In each category, Fujitsu Ethernet Tag Switching resulted in greater cost savings versus MPLS-TP.


"We found that the Fujitsu Ethernet Tag Switching implementation of COE produces lower OpEx than the MPLS-TP implementation of COE when service providers migrate from a SONET-centric to a packet-centric transport network infrastructure," said Michael Kennedy, Ph.D., principal analyst for ACG Research. "In particular, Ethernet Tag Switching goes a long way toward simplifying Operations, Administration and Maintenance (OAM) while incorporating widely-accepted Carrier Ethernet standards. The combination allows transport operations personnel to continue using the procedures and applications they've used for years, even as service delivery and transport functions become increasingly packet-based."http://us.fujitsu.com/telecom
