ADVA Tests OpenFlow for Multi-Layer Network Virtualization

ADVA Optical Networking is pioneering the use of OpenFlow technology to dynamically control wavelength-switched optical networks. Working in cooperation with the University of Essex as part of the OFELIA project, ADVA has developed an optical OpenFlow implementation based on its FSP 3000 transmission platform.

Project OFELIA provides researchers with a Software-Defined Networking (SDN) testbed to experiment with new applications using a web-services approach. The aim is to use a common OpenFlow control for both the packet and optical layers.

The SDN facility at University of Essex comprises packet switches and application servers that can be dynamically connected by optical lightpaths. External users can directly access the facility via GÉANT, a high-bandwidth pan-European backbone that interconnects national research and education networks. Web-based tools and services enable users to request network resources from OFELIA and run, control and monitor their own SDN applications.

"SDN presents a tremendous opportunity for customers to streamline and automate network infrastructure and operations,” said Christoph Glingener, CTO, ADVA Optical Networking. “While server and storage virtualization have been widely adopted, network virtualization is still in its infancy. SDN closes this gap by offering programmable network control, better scalability and faster adoption to virtual machine mobility. We have proven that SDN can seamlessly extend into the optical domain and enables network virtualization across multiple layers. The OpenFlow approach extends our existing SDN solution employing our RAYcontrol control plane."

"It has been exciting developing this OpenFlow solution with the team at ADVA Optical Networking”, commented Professor Dimitra Simeonidou, head of the High Performance Networks Group, University of Essex. “Together we have built an SDN testbed with packet and wavelength switches under a common OpenFlow control. This is something that has never been done before. Researchers can now obtain slices of network infrastructure to program their own virtual multi-layer networks. They can use optical switching alongside packet switching to adapt bandwidth, latency and power consumption to their application needs."

Telstra Announces Application Assured Networking Service

Telstra introduced an "Application Assured Networking" service that provides enterprises with more control over the increasing number of financial, relationship management, IP telephony, video conferencing and other business applications on their network. The new service will initially allow an organisation to produce reports on how networks are being used by applications which can be viewed via an easy-to-use secure online portal on the Telstra Business and Enterprise website.

Telstra said its goal is to optimise the network to ensure the performance of enterprise applications that really count. Enterprises can define application policies for the network which applies Quality of Service and bandwidth controls in real-time or as scheduled.

The new service is available on the Telstra Next IP network. Peer Industries is the first Telstra customer to use the Application Assured Networking service.

BT Stays Ahead of Schedule, Increases Dividend

BT reported overall revenue, excluding transit, of GBP 19.307 billion for the fiscal year ending 31-March-2012, down 1.9% for the year. EBITDA came in at over GBP 6 billion, a year earlier than the company's turn around plan anticipated. The company has proposed a final dividend of 5.7p, up 14%, giving a full year dividend of 8.3p, up 12%.

"In what remains a challenging environment we have delivered another year of growth in profits and free cash flow. Our financial strength has allowed us to invest in the business, make a 2bn pounds payment into the pension fund, reward employees and deliver double digit growth in shareholder returns," stated Ian Livingston, Chief Executive.

Some highlights:

Net labour costs decreased by 1% to £4,812m after adjusting for certain labour related costs of £87m classified as other costs in the prior year.

Capital expenditure was £2,594m, in line with a target for the year of around £2.6bn. BT expects capital expenditure to remain at around £2.6bn in 2013.

BT added 589,000 retail broadband customers in the year, representing 54% of the broadband market net additions of 1,085,000 and taking our retail broadband customer base to around 6.3m, up 10%.

Net additions for BT Infinity, the company's super-fast broadband service, were 131,000 in the quarter, and the customer base currently stands at over 550,000.

BT Vision added 28,000 customers in the quarter, bringing the customer base to over 700,000, up 23% on last year.

Business revenue decreased by 6% in the quarter and 5% in the year. Revenue continued to be impacted by lower IT hardware sales reflecting market conditions and a decision in the second quarter to move away from low-margin IT hardware trade sales.

Infonetics: Carrier Wi-Fi Market Takes Off

Infonetics is predicting that the global carrier WiFi equipment market will grow in the high double-digit percents annually at least through 2016, when it will hit $2.1 billion. This pace is already established as Infonetics notes that global revenue for carrier WiFi equipment -- including mobile WiFi access points, WiFi hotspot access points, and WiFi hotspot controllers -- grew 35% in 2011 from 2010.

"Our many recent conversations with mobile operators and equipment vendors validate our view that mobile operators are hot for hotspots,” notes Richard Webb, directing analyst for microwave, mobile offload, and mobile broadband devices at Infonetics Research. "The carrier WiFi equipment market has grown consistently since 2007, initially driven by exploding demand from mobile operators augmenting their 3G and 4G deployments with WiFi hotspot services. The strongest new growth driver is mobile operators deploying carrier WiFi to offload a portion of their mobile data traffic."

Some notes from the Infonetics' Carrier Wi-Fi Survey:
  • Two-thirds of the service providers that Infonetics interviewed have already deployed 20,000 to over 150,000 WiFi access points (APs) in public spaces.
  • Street coverage is seen as one of the areas of greatest deficit for WiFi coverage; by 2013, the percentage of service providers planning to deploy WiFi for street coverage jumps to 79%.
  • Complementing the mobile data service by enhancing throughput is currently the top deployment driver for carrier WiFi, followed by the scarcity of licensed spectrum.
  • Nearly all respondent carriers plan to increase the number of access points deployed by 2013, so Infonetics expects significant carrier WiFi deployment over the coming year.
  • Smartphones and tablets are named by mobile operators as the top mobile broadband devices driving their 2013 deployments of public WiFi networks.
