News Networking giant Nortel's 40/100G Adaptive Optics Engine was tested on a 217-mile length of Virgin's optical network between London and Manchester - and successfully carried 40G traffic, according to the two companies.
[09 May 2008]
News Uses of the network will include real-time traffic monitoring via CCTV, improved IT in schools and videoconferencing to help social workers carry out their jobs more effectively. The race to become the UK's first 'Fibrecity' has been won by the...

whitepaper Video is delivered as a mixture of IP multicast traffic or IP unicast traffic. The voice service can be Plain Old Telephone Service (POTS), Voice over IP (VoIP) or Voice over ATM (VoATM) with high-speed Internet access used as the data service.
[10 Apr 2008]
whitepaper In the scenario presented in this paper, data traffic leaves customer site as ATM traffic running over ADSL modem links, gets aggregated via DSLAM (DSL Access Multiplexer) at the central office (CO) and then dropped onto the high-speed ATM...

News Smart signs on the motorway give early warnings of traffic conditions, can open or close lanes and control the speed of queuing traffic. Ambitious proposals in the Highways Agency's (HA) business plan for 2008-09 will build on the success of the...
[01 Apr 2008]
whitepaper Driven by high-definition video and high-speed broadband penetration, consumer IP traffic will bolster the overall IP growth rate so that it sustains a fairly steady growth rate through 2011, growing at a Compound Annual Growth Rate (CAGR) of 46...
[28 Mar 2008]
whitepaper This paper presents the design of a next generation network traffic monitoring and analysis system, called NG-MON (Next Generation MONitoring), for high-speed networks such as 10 Gbps and above. The monitoring and analysis task in NG-MON is divided...
[04 Mar 2008]
whitepaper However, the development of IETF compliant probes so that they sustain the traffic generated in high speed networks is a current challenge, since communication links operating at 100 Mbps or higher rates require efficient packet filtering and...
[04 Mar 2008]
whitepaper The complete architecture relies on standardized protocols such as IPFIX and PSAMP for transmission of monitoring data between the monitoring elements and successive traffic analysis. This paper demonstrates the potentials of a new network...
[04 Mar 2008]
whitepaper Operators of large networks and providers of network services need to monitor and analyze the network traffic flowing through their systems. Monitoring requirements range from the long term (e.g.monitoring link utilizations, computing traffic...
[04 Mar 2008]
whitepaper A key function for network traffic monitoring and analysis is the ability to perform aggregate queries over multiple data streams. The recently proposed sketches are among the very few that can detect heavy changes online for high speed links, and...

Comment What they're talking about is prioritised traffic, 24/7 support, guaranteed uptime and so on and so forth - so if there are any challenges, those are the areas that we should be focused on - are focusing on.
[21 Feb 2008]
whitepaper In addition, the paper investigates the effect of traffic rate on link capacity in the presence of interference. Wireless mesh networks aim to provide high speed Internet service without costly network infrastructure deployment and maintenance.
[14 Feb 2008]
News He added: "We see that in the 3G networks that we monitor in Europe data traffic now exceeds voice and accelerates quickly, from between 50 to 1,500 per cent depending on the operator's strategy. Ericsson has partnered with Telstra to roll out a...

whitepaper For example, high degrees of traffic aggregation mean that even short periods of interrupted operation can disrupt a large number of traffic flows and user/subscribers, potentially violating numerous SLAs.
[07 Feb 2008]
whitepaper The UMTS has been designed to address specifically the needs of data traffic. UMTS constitutes the third generation of cellular wireless networks which aims to provide high-speed data access along with real time voice calls.
[14 Jan 2008]
whitepaper Bulk data transfer and interactive traffic was considered in the simulation. Universal Mobile Telecommunications System (UMTS) is a third-generation cellular network that enables high-speed wireless Internet access.
