The New Open Source Networking Universe, managed by The Linux Foundation

This month's Open Networking Summit (ONS 2017) in Silicon Valley, which marked the sixth instalment of the annual event since its origin at Stanford University, once again brought many key thought leaders together for keynotes, tutorials, conference sessions, panel discussions and a small exhibition. ONS was the event that set off alarm bells across the industry in 2012 when Google announced that SDN had moved well beyond the research phase and into its commercial network, using a home-grown solution and no routing equipment from conventional vendors.

As far as the current state of open source networking is concerned, perhaps Margaret Chiosi, formerly at AT&T and now with Huawei, put it best, commenting (paraphrased from her keynote), 'open networking has reached the peak of exuberance and not yet crossed the chasm of despair'. In other words, great ideas are flourishing but no one is yet really making money or saving money with open networking. In addition, Guru Parulkar, executive director of ON.Lab, observed that while there are many proof-of-concepts and early deployments, a 'resource gap' of qualified professionals may delay large scale deployments. New technology is difficult and committed resources must be in place if network transformations are to really happen.

ONS 2017 was presented by The Linux Foundation, the San Francisco-based organisation with the lofty ambition of creating the 'largest shared technology investment' in history. A mural at the entrance to the exhibition depicts the New Open Source Networking Universe, and certainly a tremendous amount of intellectual capital is being collected, curated and assembled into specifications and frameworks impacting every layer of the network.

The following is the line-up of networking related projects underway at the Linux Foundation (although there are more non-networking LF projects and other open source networking projects, such as Open Stack, that are not managed by LF).

ONAP

The Open Network Automation Platform (ONAP) unites two major open networking and orchestration projects, AT&T's open source ECOMP and the Open Orchestrator Project (OPEN-O). This newly launched LF project is one of the largest open source networking initiatives, with members including Amdocs, AT&T, Bell Canada, China Mobile, China Telecom, Cisco, Ericsson, GigaSpaces, Huawei, IBM, Intel, Metaswitch, Nokia, Orange, Tech Mahindra, Reliance Jio, VMware, ZTE and other leading network operators, OEMs and platform providers.

OPNFV

A carrier-grade, integrated, open source platform to accelerate the introduction of new NFV products and services. OPNFV is mainly focused on building NFV Infrastructure (NFVI) and Virtualized Infrastructure Management (VIM) by integrating components from upstream projects such as OpenDaylight, OpenStack, Ceph Storage, KVM, Open vSwitch and Linux. At ONS 2017, OPNFV made its 4th major release, codenamed Danube, adding foundational support for MANO. The next release, codenamed Euphrates and targeted for completion by October, is expected to include more containerisation support.

Open Daylight

One of the largest projects, this promotes and advances the global development, distribution, and adoption of the OpenDaylight (ODL), the largest open source SDN controller. Many industry vendors participate in ODL.

ONOS

A SDN operating system for service providers that has scalability, high availability, high performance and abstractions to make it easy to create applications and services. At ONS 2017 the ONOS community made its next platform release, adding support for IPv6 routing, vLAN tagged external interfaces and AAA endpoint authentication, a better GUI interface, VPLS support and various southbound enhancements. Notable members of the ONOS community include AT&T, Comcast, China Unicom, Google, NTT Communications, SK Telecom and Verizon.

CORD

Central Office Re-architected as a Data Center (CORD) combines NFV, SDN and the elasticity of commodity clouds to bring data centre economics and cloud agility to the telco central office (CO). CORD lets the operator manage central offices using declarative modelling languages for agile, real-time configuration of new customer services. Three versions are underway - Mobile CORD, Residential CORD, Enterprise CORD – and each has multiple proof-of-concept demos.

DPDK

The Data Plane Development Kit (DPDK) consists of libraries to accelerate packet processing workloads running on a wide variety of CPU architectures. DPDK was created in 2010 by Intel and made available under a permissive open source license. Today, more than 20 key open source projects build on DPDK libraries, including MoonGen, mTCP, Ostinato, Lagopus, Fast Data (FD.io), Open vSwitch, OPNFV, and OpenStack. This community has just moved to the Linux Foundation. Gold members of the project are ARM, AT&T, Cavium, Intel, Mellanox, NXP, Red Hat, and ZTE; Silver members include 6WIND, Atomic Rules, Huawei, Spirent, and Wind River. The Korea Advanced Institute of Science and Technology (KAIST), University of Limerick, University of Massachusetts Lowell and Tsinghua University are Associate members.

FRRouting (FRR)

Free range routing (FRR) is a project endeavouring to make the best open source routing stack. FRR, which originated in the Quagga project, includes protocol daemons for BGP, IS-IS, LDP, OSPF, PIM and RIP. At ONS, it was announced that this project will now be managed by the Linux Foundation.

Open Switch (OVS)

An open-source implementation of a distributed virtual multi-layer switch, the main purpose of Open vSwitch is to provide a switching stack for hardware virtualisation in a network.

PNDA

Platform for Network Data Analytics (PNDA) aims to eliminate complexity by integrating, scaling and managing a set of open data processing technologies and by providing an end-to- end platform for deploying analytics applications and services. The big idea is that open source big data analytics can play in accelerating the transition to more agile, assured and orchestrated services. At ONS 2017, the MEF demonstrated a reference implementation of LSO (Lifecycle Services Orchestration) analytics using PNDA.

AllJoyn

AllJoyn is developing an open source framework for IoT.

Cloud Foundry

Cloud Foundry aims to make it faster and easier to build, test, deploy and scale applications.

The Cloud Native Computing Foundation

OpenStack User Survey Finds Increasing Deployments

The OpenStack Foundation announced that its user survey for 2016 showed that it achieved 44% more deployments and gained input from 22% more organisations than a year ago, while also revealing increased scale of deployments and a more diverse user base as users seek to avoid vendor lock-in.

OpenStack notes that the ninth user survey indicates that the open infrastructure platform for private and public clouds and telecom networks has growing appeal for organisations of all sizes. Specifically, the survey shows that 32% of users have 10,000 employees or more and 25% of organisations have fewer than 100 employees, with around 61% of users and 74% of deployments physically located outside of the U.S.

In addition, OpenStack notes that the typical (median) OpenStack user is running 61% to 80% of infrastructure on OpenStack, while for larger clouds with 1,000 cores or more, the median user is running 81% to 100% of the overall infrastructure on OpenStack.

Further key findings revealed by the OpenStack user survey include:

1.         The typical size of an OpenStack cloud increased, with 37% of clouds having 1,000 or more cores, compared to 29% in 2015, and 3% of clouds with more than 100,000 cores; the number of users operating Nova cells increased by 218%.

2.         Swift object provisioning also showed increased scale, with 16% of deployments provisioning more than 1 petabyte of object storage (4% last year), while 33% reported storing 100,000 or more objects (13% last year).

3.         The business drivers for OpenStack adoption highlight its competitive advantages, including accelerated innovation and avoiding vendor-lock in; respondents stated that these factors are more important than reducing costs and increasing operational efficiency, which ranked No. 1 and 2 in past surveys.

4.         Containers remain the leading technology of interest to users, with 65% of those running OpenStack services inside containers using Docker runtime, while 47% of those using containers to orchestrate apps on OpenStack employing Kubernetes.

5.         The proportion of OpenStack deployments in production remains stable, with around two-thirds of clouds in production, while number of clouds in proof-of-concept and test stages indicating healthy growth for the future.

6.         A typical deployment runs nine projects, with 16% running 12 or more projects; all of OpenStack's core services are in use by 89–98% of clouds, significantly higher than last year for core projects in production.

Vodafone Turkey Tests GL Spectrum Sharing with Huawei

Vodafone Turkey and Huawei announced they have completed what they claim is the first verification of the GL spectrum sharing solution on Vodafone's commercial 900 MHz networks in the city of Diyarbakir in Turkey.

This solution, developed through a collaboration on spectrum sharing capabilities between Huawei Mobile Innovation Centre and Vodafone Networks CoE (Center of Excellence), enables spectrum sharing between GSM and LTE with a high degree of overlap between the two technologies. The technology improves both LTE data rate and cell capacity available in the 900 MHz spectrum allocation from Vodafone Turkey.

Huawei claims that compared to LTE 5 MHz performance, the GL technology enables average user data throughput to be increased by nearly 58% on the downlink and 44% on the uplink.

Vodafone Turkey launched its 4.5G network for commercial use in April 2016 and claims to offer the largest 4.5G coverage in Turkey, currently serving over 8 million LTE customers. Subsequently, as more users migrate to LTE the effective allocation of spectrum resources to support increasing LTE data traffic has become a priority for Vodafone Turkey. The GL spectrum sharing solution features Huawei's proprietary algorithms, which are designed to free operators from the restrictions of standard LTE bandwidth.

The Huawei solution ensures that scattered spectrum resources are utilised more effectively to enable higher data rates and an enhanced user experience. By providing more flexibility in terms of the resource block allocation and spectrum allocation effectively used by LTE the GL technology also maintains sufficient GSM channels to carry 2G CS traffic.

In February, Huawei, Vodafone and Qualcomm Technologies announced they had jointly created in Turkey what they claimed was the first network ready to use Licensed-Assisted Access (LAA) technology, based on the 3GPP R13 standard. LAA is designed to help improve the user experience by enabling faster download speeds.

The LAA-ready network was tested using a Huawei Lampsite base station in a Vodafone Turkey store in Istanbul and used 40 MHz of unlicensed spectrum in 5 GHz and 15 MHz licensed spectrum in 2.6 GHz for three carrier aggregation. The on-site peak download speed of 370 Mbit/s was achieved using a Qualcomm Snapdragon 835 processor with X16 LTE mobile test device



  • In 2016, Huawei announced that its Active Antenna Unit (AAU) solution was supporting Turkey's deployment of 4.5G networks to enable enhanced mobile broadband (MBB) services. Turkey launched its large-scale plan for the evolution from 3G to 4.5G networks in 2015 and released the first 4.5G spectrum license in August of that year.

Rambus teams with Samsung to offer 56G SerDes PHY

Rambus, a supplier of hardware and software technologies for the communications market, announced that it is partnering with Samsung Electronics to develop its recently launched 56 Gbit/s SerDes PHY on Samsung's 10 nm LPP (low-power plus) process technology.

Rambus' 56 Gbit/s SerDes PHY is designed to deliver enterprise-class performance in challenging signalling environments typical for high-speed communication systems and provides PAM4 and NRZ signalling with a scalable ADC-based architecture. The flexible device architecture targets long-reach backplane requirements to support the transition to 400 Gigabit Ethernet applications.

Rambus unveiled the 56 Gbit/s multi-protocol SerDes PHY, developed on advanced, second generation FinFET process technology, in February this year. The solution is designed to address demanding communications and data centre applications.

Calix Launches Marketing Cloud

Calix, the provider of Subscriber Driven Intelligent Access, announced the release of Calix Marketing Cloud (CMC), a new cloud solution that builds on the company's five years of cloud-based customer support.

Calix noted that marketing teams at service providers may have access to limited, static subscriber data from billing and data consumption, which does not provide insight into subscriber usage and preference trends. The new CMC solution enables better understanding of subscribers by aggregating behavioural data, allowing the marketer to create, target and execute more effective campaigns.

Calix's CMC features behavioural filters that allow the creation of actionable lists of target subscribers extracted directly from back-office systems, which can then loaded into focused marketing campaigns.

The new cloud-based CMC solution delivers key behavioural information to service providers' marketing teams, including:

1.         Subscriber insights: via a nightly data refresh, CMC reveals trends in a single dashboard view, with an emphasis on identifying subscribers that may be interested in a service upgrade and those prone to churn.

2.         Customer segmentation: designed to simplify the segmentation process, providing detailed breakdowns of user types such as gamers, social media enthusiasts and over-the-top (OTT) service users, enabling the creation of contextually relevant product bundles and marketing content and targeted campaigns.

3.         Targeted campaigns: based on subscriber segmentation, CMC allows the export of target groups into automated marketing engines such as Salesforce Pardot or Marketo, for bill inserts, online campaigns via the best social media channel, or campaigns loaded into a CRM system.
