RSS considersOptimal Routing With Multiple Traf?c Matrices Tradeoff Between Average and Worst Case Performance
White Paper This paper considers the problem of finding an "Efficient" and "Robust" set of routes in the face of changing/uncertain traffic. The changes/uncertainty in exogenous traffic is characterized by multiple traffic matrices. [18 Jul 2008]
Non-Adaptive Fault Diagnosis for All-Optical Networks Via Combinatorial Group Testing on Graphs
White Paper This paper considers the fault diagnosis problem in all-optical networks, focusing on probing schemes to detect faults. This paper work concentrates on non-adaptive probing schemes, in order to meet the stringent time requirements for fault recovery. [18 Jul 2008]
On Multicasting in Wavelength-Routing Mesh Networks
White Paper This paper considers multicasting on wavelength-routing mesh optical networks. Although multicasting has been studied extensively in different network environments, multicasting in this environment is different, and more involved. [18 Jul 2008]
Insecurity in ATM-Based Passive Optical Networks
White Paper This paper considers the security of an ITU standard for ATM-based passive optical networks. First, it shows that the standard's encryption algorithm, called churning, has an effective 8-bit key length and thus is trivial to break with exhaustive... [18 Jul 2008]
Optimal Routing With Multiple Traffic Matrices Tradeoff Between Average Case and Worst Case Performance
White Paper This paper considers the problem of finding an "Efficient" and "Robust" set of routes in the face of changing/uncertain traffic. The changes/uncertainty in exogenous traffic is characterized by multiple traffic matrices. [18 Jul 2008]
QoS Perspective for Wireless Scenarios
White Paper This paper considers that each layer parameters essentially contribute to the global QoS evaluation. Generally speaking, a service is finally defined by quality parameters. In particular, telecommunications services are evaluated by a set of... [18 Jul 2008]
Optimizing Request Denial and Latency in an Agent-Based VPN Architecture
White Paper This paper considers the problem of connecting users of an organization to an optimal VPN server location so that request denial probability and latency are balanced. Agent-Based Virtual private networks Architecture (ABVA) refers to the... [18 Jul 2008]
QoS Topology Control in Ad Hoc Wireless Networks
White Paper The paper considers two cases of the problem: the traffic demands are not splittable, and the traffic demands are splittable. This paper discusses the energy efficient QoS topology control problem in ad hoc wireless networks. [18 Jul 2008]
A Vision Based Approach to Wireless Optical Networking
White Paper This paper considers that this approach provides not only a redundant, secure means for wireless communication, but also a medium for enabling networking through non-traditional devices (e.g.television monitors) widely available throughout the... [18 Jul 2008]
O2 considers high fibre rollout
News O2 is considering investing in its own fibre-to-the-home network but wants to wait until Ofcom changes telecommunications regulation before it makes an investment. Following BT's Tuesday announcement that it was to plough £1.5bn into a fibre-access... [17 Jul 2008]
Protocols for Communication Between QoS Agents: COPS and SDP
White Paper This paper considers two protocols that can be used for the communication between the QoS agents and a QoS management tool in an architecture developed. One solution to ensure QoS needed by multimedia applications is to start the requests directly... [17 Jul 2008]
Snap-in, Grid-Based Data Integration: IBM Information Server Blade
White Paper Specifically, the paper considers the problems posed by the complexity of "data integration" technology in terms of its configuration and maintenance. It looks at the utility of a grid computing approach in providing scalability and manageability... [14 Jul 2008]
Efficient Use of Memory Bandwidth to Improve Network Processor Throughput
White Paper This paper considers the efficiency of packet buffers used in packet switches built using Network Processors (NPs). Packet buffers are typically implemented using DRAM, which provides plentiful buffering at a reasonable cost. [11 Jul 2008]
Network Protection Design for MPLS Networks
White Paper This paper considers the problem of designing partially and fully survivable explicit label switched paths for MPLS networks. These problems are model as Mixed Integer Linear Programs. Furthermore, it presents a survivability assessment of the models. [11 Jul 2008]
Proportionally Fair Allocation of End-to-End Bandwidth in STDMA Wireless Networks
White Paper This paper considers the problem of designing distributed mechanisms for joint congestion control and resource allocation in spatial-reuse TDMA wireless networks. The design problem is posed as a utility maximization subject to link rate... [11 Jul 2008]
