Blueprint: Is Wi-Fi Innovation Slowing Down?

by Jay Botelho, Director of Product Management for Savvius, Inc.

Wi-Fi technology has improved our daily lives in ways unimaginable just a few years ago. We routinely connect to our own personal digital universe from the comfort of our living room, while sitting at a local coffee shop, or even from the passenger seat of a new car. Yet for all of the amazing progress Wi-Fi has made over the years, are we witnessing the end of rapid WLAN innovation? Have we reached a point where ‘fast’ is fast enough? After all, it seems to take longer for organizations and even consumers to embrace each new iteration of this ubiquitous wireless standard.

No one would deny that Wi-Fi technology has come a long way since it burst onto the market fifteen years ago. In that relatively short period, Wi-Fi’s maximum data rate has increased by a factor of 150. For the sake of comparison, the original 802.11b standard had a maximum throughput of 11 megabits per second (Mbps), while the latest 802.11ac 4-stream client device has a throughput of 1.7 gigabits per second (Gbps), or 1,700 Mbps, an amazing improvement.

Tracking the Leaps in Wi-Fi Performance

After 802.11b came three major leaps in Wi-Fi technology: 802.11a/g in 2003; 802.11n in 2009; and 802.11ac in 2014. The improvements in speed, range and intelligence of each successive standard have been remarkable.

802.11a raised the maximum theoretical data rate from 11Mbps to 54 Mbps, and used the 5Ghz band to avoid the degradation issues commonly faced by 11b’s overcrowded 2.4GHz band. 11a also performs better in crowded indoor environments such as offices, though the signals are more easily absorbed by solid objects such as walls, giving them a shorter range.

802.11g, ratified in 2003, extended throughput to 54 Mbps in the 2.4GHz band by using some of the same orthogonal frequency-division multiplexing (OFDM) transmission technology found in 802.11a. Like 802.11b, 802.11g devices suffer from interference due to overcrowding of the 2.4GHz band from digital phones, microwave ovens, and other electronics such as Bluetooth devices.

The next major performance boost came in 2009 with the introduction of 802.11n. This standard uses both the 2.4 and 5GHz bands and multiple antennas to increase the maximum theoretical data rate to 600 Mbps. Now with four spatial streams at a channel width of 40 MHz, 11n supports features for better security and multiple-input multiple-output (MIMO).

802.11ac was announced with a lot of fanfare in early 2014, with the goal of providing data rates of up to 7 Gbps in the 5GHz band. In real environments that level of throughput is unrealistic, but getting 1.7 Gbps is entirely possible with a four-stream client device. The limiting factor with 802.11ac devices is usually the number of antennas. 11ac can support up to eight, each running at 400 Mbps. However, most routers only have four antennas and most devices have fewer than that. Smartphones with only one antenna, for example, will not be able to take advantage of an 802.11ac network’s capacity. Regardless, these speeds are much higher than almost all home broadband connections, and certainly higher than what was possible with 11n just a few years prior. The technology is here today – it’s just not being used to its full potential, yet.

The Proliferation of Wi-Fi into Everyday Devices

So if the advancement of the technology isn’t slowing down, why does progress sometimes seem to be faltering? There are multiple factors. One of the simplest reasons is that Wi-Fi is being embedded into so many products, from PCs to thermostats, that updating each of them to support a new standard is a massive undertaking. Add to that the need to ‘future-proof’ these products with features that may not be needed for a year or two, and the problem becomes more clear. With each successive new standard, products trickle onto the market slowly until production costs fall, but that doesn’t happen until economies of scale are reached. For all the speed offered by 802.11ac, there are still relatively few devices that take full advantage of it, and without those benefits it is hard to convince businesses or consumers to upgrade.

Each subsequent generation of Wi-Fi standards has run into initial obstacles that quickly yielded to astounding growth, and there is no reason to think that pattern will end soon. Once a technology is in place, innovative companies and consumer pressure soon find ways to exploit it, just as we saw with the explosive growth of WLAN innovation thanks to drivers such as 4K video streaming. The 802.11ax standard currently in development is expected to offer a theoretical 10 Gbps or higher. This has the potential to translate into real-world speeds higher than 2 Gbps. It will take a lot of creativity to use that bandwidth effectively, but it will happen. So, to answer my original question, “are we seeing the end of rapid WLAN innovation?” The answer, in my opinion, is a definite no.

Cisco Adds ACI Security Features and Docker Support

Cisco announced a new software release for its Application Centric Infrastructure (ACI) that adds microsegmentation for both physical (bare metal) applications and multivendor virtualized applications (VMware VDS, Microsoft Hyper-V). New features extend ACI across multi-site environments to deliver policy-driven automation across multiple data centers. The update also adds support for Docker containers through contributions to open source.

Cisco said its ACI now supports automated service insertion for any third party layer 4-7 service and cloud automation tools like VMware vRealize Automation and OpenStack, including open standards-based Opflex support with Open vSwitch (OVS).

“Customers tell me that only five to ten percent of their networks are automated today,” said Soni Jiandani, SVP at Cisco. “They are eager to adopt comprehensive automation for their networks and network services through a single pane of management, while improving security for east-west traffic, multi-cloud traffic and bare metal applications in a consistent manner. Policy-based automation, consistent network security and central compliance support are critical for IT efficiency, business agility, and competitive advantage. Several ACI customers have achieved full automation of the network and are focusing on automation across their Layer 4-7 network services, security and application groups as the next step.”

Cisco ACI Software Release highlights:

Docker Container Support: Cisco delivers support for both physical and virtual endpoints, and now extends support for Docker container endpoints through integration with the Cisco Application Policy Infrastructure Controller (APIC) and Project Contiv. Project Contiv is an open source project defining infrastructure operational policies for container-based application deployment. ACI’s unified policy model enforces policy via endpoint groups (EPG), a collection of network endpoints that includes a wide range of entities, including bare-metal servers, virtual machines, and containers.  Docker offers an open source platform for running distributed applications in Linux containers.

Enhanced security: Cisco ACI now provides micro-segmentation support for VMware VDS, Microsoft Hyper-V virtual switch, and bare-metal applications, which allows granular endpoint security enforcement. Customers can dynamically enforce forwarding and security policies and quarantine compromised or rogue end points based on virtual machine attributes (such as Name, Guest OS, VM Identifier) or network attributes (such as IP address.) Organizations can also isolate workloads within the same policy group. For example, communication between all endpoints within the same web tier can be disabled through policy-based automation, which prevents security threats from moving laterally within the data center.

Support for multiple data centers: Cisco ACI now delivers consistent policy-driven automation across multiple data centers to enable application mobility and disaster recovery through the new multi-site application in the ACI toolkit.

Cisco ACI now also supports service insertion and chaining for any service device, without the need for a device package for policy coordination with the Cisco APIC. Customers can now seamlessly configure and manage all their existing network services, while automating network services connectivity.

Increased operational flexibility: Additional software capabilities provide:  support for NX-OS style Command Line Interface (CLI) for APIC, Basic and Advanced GUI modes, Simple Network Management Protocol (SNMP) support for APIC, and trouble-shooting wizard enhancements such as Heat Map. General availability is Q4 CY 2015.

Cloud automation tools: Adding to its support for Microsoft AzurePack for private cloud, Cisco now offers full policy-based cloud automation with VMware vRealize Automation and also OpenStack deployments. Cisco is extending ACI policy directly to the hypervisor using Opflex on Open vSwitch (OVS). OpFlex provides the policy-based integration between OpenStack and APIC. These will be generally available in Q4 CY 2015.

ACI Ecosystem expands to 47 members: In addition to CliQr, DataTorrent, and Vnomic, four new members that expand complete application and cloud services for ACI deployments have joined the ACI ecosystem: Apprenda, KillerIT, One Convergence and ScienceLogic.

Cisco also noted that it now has over 5000 Nexus 9000 ACI-ready customers using its open platform.

ONOS Enters 5th Release for Carrier-Grade SDN

ONOS, the open source SDN networking operating system for Service Provider networks, released its fifth generation platform.

"When we initially released ONOS, our goal was to provide a solid platform that would act as a base on which ON.Lab, its partners and the community could rapidly develop a number of SDN applications," said Thomas Vachuska, Chief Architect at ON.Lab's ONOS project. "ONOS' growing list of SDN and NFV use cases and solutions is a testament to the robustness of its initial distributed architecture design. Even as we add more features, it continues to provide high availability, scalability, performance, and the rich north- and southbound abstractions required for service provider and mission critical networks."

The Emu release, which keeps to a quarterly update cycle, brings improvements to the platform such as IP Multicast and SDN-IP and key use cases including Central Office Re-Architected as a Data Center (CORD), Packet/Optical, service function chaining (SFC) and support for the Open Platform for NFV Project (OPNFV) and OpenStack. Expanding capabilities and advancements include:

OPNFV and OpenStack - In order to become a controller option with OPNFV's upcoming Brahmaputra release, Emu can integrate with OPNFV and OpenStack to provide an easy pathway to future VNFaaS and NFV management and orchestration capabilities. In addition, SK Telecom is leading a project called Simplified Overlay Networking Architecture (SONA), which will ease deployment of software defined data centers, where they have provided OpenStack Switching and OpenStack interfaces for CORD.

Resource Reservation Subsystem - Fujitsu has contributed a general purpose reservation system to replace the previous ones, supporting a single, consistent interface and semantics for different types of resources. The new subsystem is also more easily extensible to new types of resources that operators may wish to bring under ONOS' control.

IP Multicast – DirecTV continues to contribute to the multicast infrastructure. To support multicast use cases and applications the project created the ONOS Multicast Forwarding Application (MFWD). The multicast apps MFWD and Protocol Independent Multicast (PIM) support PIM-SSM Hello and Join/Prune as well as static multicast routes. The ONOS multicast architecture is composed of the following primary components; the Multicast Route Table that maintains Multicast ASM and SSM forwarding state within the ONOS controller, the MulticastForwarding module which responds to live multicast data traffic, the MulticastIntentManager responsible for interacting with the ONOS IntentService which in turn establishes paths through the network.

GUIs - ONOS adds the MFWD CLI and REST APIs that allow external operators and applications to examine and modify the existing MFWD state. The UI adds new archetypes for views as well as a new overlay for Badged nodes and both facilitate the ability to customize the user's view of the network.

Service Function Chaining - Huawei has contributed significant enhancements to the virtual tenant network (VTN) system to enable ONOS to provide Layer 2 and Layer 3 (L2, L3…) virtual networks as well as IETF's Service Function Chaining (SFC). New capabilities include a set of new northbound APIs for creating SFC. These include creating port-pairing for virtual functions, port-pair-grouping for load balancing of virtual functions, flow-classifiers (L2, L3 and L4) and port-chains for function chaining. ONOS implemented an SFC control plane in ONOS by creating an SFC Manager that includes classification and forwarding behavior construction.  New L3 features are: east - west bound communication between different subnets for the same as well as different tenants; south-north bound communication including floating IP and device modeling for external traffic; and the ability to do live virtual machine migrations and to add L3 services in the data path.

CORD – CORD brings a new architecture to the CO that began with a residential subscriber PoC at ONS2015 that will become a field trial with AT&T in the first half of 2016. The trial will also add support for mobile and enterprise PoC's in 2016. New Meter and QinQ support enable more QoS and Policing features. Additionally, SK Telecom helped develop initial implementations of infrastructure support for virtual networks and network services for CORD for the delivery of mobile network use cases.

Adaptive Flow Monitoring - Korea's Electronics and Telecommunications Research Institute (ETRI) has added infrastructure upgrades for ONOS to perform adaptive flow monitoring. Monitoring can now be used to debug flows inline. Network traffic monitoring is a fundamental function that can be used to operate and manage a network stably and efficiently. To do this many network management systems require accurate network resource status information in real-time. In order to provide such information in an inexpensive but accurate way, ONOS adds an adaptive flow monitoring subsystem with an efficient sampling algorithm. Selective Deep Packet Inspection (DPI) subsystem in ONOS will be added in future iterations as ONOS plans to develop the subsystem in two phases for its OPEN-TAM functionality subproject.

SDN -IP - is an ONOS application that allows Software Defined Networks to connect to external networks, legacy or software-defined, using the standard Border Gateway Protocol (BGP). It is a key element of ONF's Atrium distribution. The SDN-IP app benefits from the new configuration subsystem announced in Drake by delivering remarkably easy app configuration with Emu enabling reconfiguration of this app at run-time so it can add or remove peers dynamically. Emu also adds default route support in SDN-IP based on the IETF's RFC 4632 standard. In legacy networks, if the router does not have a matchable IP prefix then it will send the packet to the next hop in the default route. Similarly in SDN-IP, if a peer announced a default route then it means that, if you do not know where to route the traffic, you can send it to that peer and it will route the traffic for you. Another benefit of using default route is to reduce the route table size.

Reactive Routing – Reactive routing for SDN-IP can work with and without BGP, however, without BGP it can only handle routing inside local networks. This is due to the situation where reactive routing does not initiate a route discovery process until a route to a new destination is required. It leads to higher latency but delivers lower overhead for slim yet nimble deployments where more is required from fewer hardware resources.

ONOSFW - To deliver ONOS support for OPNFV, ONOS launched the ONOS Framework project (ONOSFW) in the OPNFV open source community. A Virtual Infrastructure Manager (VIM) is a required component used in NFV architecture to manage and control virtualized resources via coordination between OpenStack and the SDN controller. ONOSFW builds the interfaces for ONOS to communicate with OpenStack Neutron's Modular Layer 2 (ML2) plugin, which is a framework allowing OpenStack networking to simultaneously utilize the variety of layer 2 networking technologies found in complex real-world data centers. In terms of functionality, ONOSFW provides VTN, Layer 2, Layer 3 and SFC services in ONOS enabling applications to build tenant-based services on top of ONOS.

Border Gateway Protocols with Link State Distribution (BGP-LS) - On the southbound, Emu adds Border Gateway Protocol with Link State Distribution extension (BGP-LS) as a plug-in to the ONOS controller to collect topology information from the network and make it available to other apps. This topology data can be used by applications such as PCE that can benefit from visibility outside one area or Autonomous System (AS) in order to make better decisions for path computations system-wide.

SDN controllers require complete topology information from the networks they manage to customize them for performance improvements by delivering efficient usage of network resources. In the future, using BGP-LS any app such as PCE or ALTO servers can use new IP topology subsystem to create services for their own use case scenarios. In the southbound, BGP-LS learns all the link state information from IGP in the network, through which it learns the network topology along with the network's traffic engineering parameters.

OTN and Packet Optical Support – ONOS improved the resource reservation API. ECI enhanced ONOS' optical application to support ODU Multiplexing and ODU Cross-Connect services based on OpenFlow (ONF) Optical Transport Protocol Extensions with OCH and ODU Multiplexing with the southbound interfaces based on ONF standards. This enhancement includes support in the creation, deletion and restoration of data paths. The firms are jointly working to deliver ONOS in another packet-optical proof of concept. ECI has successfully demonstrated these features with ONOS over its own optical equipment and this capability will be available to any equipment that supports OpenFlow optical extensions that is using Emu or future versions of ONOS.

OpenFastPath Targets High Performance User Space TCP/IP

A new OpenFastPath (OFP) Foundation has been established with a mission of creating an open-source community around a standardized, accelerated TCP/IP stack that provides top performance for SDN-ready network functions. For operator networks, the new fast-path stack aims to deliver reduced IP latency, higher capacity and thus faster packet forwarding, and lower implementation costs.

The OFP TCP/IP stack implementation is based on the open-source Free Berkeley Software Distribution (FreeBSD) operating system, and includes User Datagram Protocol (UDP), Transmission Control Protocol (TCP), and Internet Control Message Protocol (ICMP). New functions will be added in the future. Optimized for OpenDataPlane (ODP) programming interfaces, with a focus on leveraging hardware acceleration through ODP. Will be available for all major processor architectures, including ARM, x86, MIPS and PowerPC. - 

Founding members of the OFP are Nokia Networks, ARM and Enea. The initiative is also supported by several industry players including AMD, Cavium, Freescale, Hewlett-Packard and Linaro.

Verizon Labs taps EMC for Software-defined Storage
