Efficiently Monitoring Bandwidth and Latency in IP Networks
White Paper Unlike earlier approaches, the measurement architecture assumes a single point-of-control in the network that is responsible for gathering bandwidth and latency information using widely-deployed management tools, like... [19 Sep 2008]
Feasibility of Flow-Based Optical Provisioning in GEANT
White Paper On the other hand, data transmission has to be routed on a packet-by-packet basis to be cost effective. Historically, telephone calls were injected into circuits at the edge of the... [11 Sep 2008]
MPLS VPNs: Layer 2 or Layer 3? Understanding the Choice
White Paper Since there's been data networking, there's been a debate between switched and routed architectures - stated in OSI terms, between performing functions at Layer 3 or Layer 2. Today, we see it again... [02 Sep 2008]
Virtual Private Networks: IPSec Vs. SSL
White Paper VPNs use secure protocols to provide private communications over the Internet; they also connect the private corporate network to home-office employees, or to a remote business site through virtual connections... [04 Aug 2008]
Sweden's HL Display Picks Expand Networks for Server Centralisation and Faster WAN
White Paper Each part of the group has a back-up server but all email has been routed via the server hall in Sundsvall in northern Sweden. HL Display's partner, IT consultancy XLENT, operates the firm's network and... [04 Aug 2008]
A Column-Generation and Branch-and-Cut Approach to the Bandwidth-Packing Problem
White Paper The bandwidth-packing problem is a combinatorial optimization problem arising from telecommunication networks where demand exceeds capacity and where point-to-point calls with varying bandwidths are... [11 Jul 2008]
Performance Analysis of MPLS TE Queues for QoS Routing
White Paper In order to maximize network resources, Multi-Protocol Label Switching (MPLS) Traffic Engineering (TE) is used in IP networks so that traffic can be routed on a path which may not be... [11 Jul 2008]
The Management of MPLS LSPs for Scalable QoS Service Provision
White Paper It has a long history in the field of data communications and provides the means by which a great deal of today's data traffic is routed across networks. Indeed there is... [03 Jul 2008]
Multi Protocol Label Switching (MPLS)
White Paper In MPLS networks, the packets are labeled on the edge of the network and they are routed through the network based on simple labels. As mission-critical... [25 Jun 2008]
The Weekly Round-Up: 28.03.08
Round-Up Travellers on UK airlines who simply can't go a couple of hours without calling the office or loved ones, or possibly loved ones in the office, will be able to take advantage of the aircraft's network services and be... [28 Mar 2008]
How closely are you monitoring?
Comment Systems management tools will often include the necessary monitoring functions to let IT managers view many different facets of a computing infrastructure, from the lower levels of the computing stack, where IP traffic is... [10 Dec 2007]
UK in-flight calls get green light
News Mobile users can then use the aircraft's network service to make and receive calls, which will be routed via a satellite link to the network on the ground with calls billed through the... [18 Oct 2007]
HEAT: Scalable Routing in Wireless Mesh Networks Using Temperature Fields
White Paper Every node is assigned a temperature value, and packets are routed along increasing temperature values until they reach any of the Internet gateways, which are modeled as heat sources. This paper proposes HEAT, an... [01 Aug 2007]
Understanding the IPSec Protocol Suite
White Paper IP's strength lies in its easily and flexibly routed packets - the small, manageable chunks into which it breaks the data stream for transmission through the network. Because these... [22 Jun 2007]
VoIP threats to watch out for
Comment While emails can sit on a server for an extra hour to go through a spam filter, calls must be routed to the recipient instantly. The beauty of converged networks is that voice over IP is 'just' another... [09 Mar 2007]
