RSS failuresA Backup Route Aware Routing Protocol - Fast Recovery From Transient Routing Failures
White Paper As the Internet becomes the critical information infrastructure for both personal and business applications, survivable routing protocols need to be designed that maintain the performance of those services in the presence of failures. [18 Jul 2008]
Classification of Two-Link Failures for All-Optical Networks
White Paper Algorithms addressing link failures must provide high-speed recovery through distributed operations on flexible topologies, and must simultaneously balance efficiency against efficacy. This paper examines the relationship between the design of... [18 Jul 2008]
Preconfiguring IP-Over-Optical Networks to Handle Router Failures and Unpredictable Traffic
White Paper This paper considers the realization of traffic-oblivious routing in IP-over-Optical networks where routers are interconnected over a switched optical backbone. The traffic-oblivious routing the paper considers is a scheme where incoming traffic is... [18 Jul 2008]
A Network Management Architecture for Robust Packet Routing in Mesh Optical Access Networks
White Paper The architecture allows for bandwidth sharing within a wavelength and is robust to both link and node failures. The architecture can be utilized with an arbitrary, link-redundant mesh network (node-redundancy is necessary only to handle all node... [18 Jul 2008]
A Novel Method for QoS Provisioning With Protection in GMPLS Networks
White Paper The objective of the proposed policy is to use ITE to set up virtual tunnels at the MPLS and optical level and protect them against failures. In this paper, a new optimal policy is introduced to determine, adapt, and protect the Generalized... [18 Jul 2008]
Privacy watchdog to get power to raid
News The Poynter Review recently highlighted systematic data handling failures in the HM Revenue & Customs that led to it losing the personal details of 25 million people. The UK's privacy watchdog could get new powers to raid organisations under... [17 Jul 2008]
Local Recovery Solutions From Multi-Link Failures in MPLS-TE Networks With Probable Failure Patterns
White Paper MPLS TE Fast Reroute proposes a local protection mechanism to quickly reroute protected TE LSPs onto pre-computed and signaled bypass tunnels. This paper explores the case of multiple network element failure scenarios. [11 Jul 2008]
Scalability of Network-Failure Resilience
White Paper This work quantifies scalability of network resilience upon failures. It characterize resilience as the percentage of lost traffic upon failures and define scalability as the growth rate of the percentage of lost traffic with respect to network... [11 Jul 2008]
Minimum Failure Explanations for Path Vector Routing Changes
White Paper However, inferring the exact topological changes behind observed routing changes may not be possible due to limited information, and the same changes may be explained by more than one set of candidate failures. [11 Jul 2008]
Differentiated Quality-of-Protection Provisioning in Optical/MPLS Networks
White Paper This paper investigates the problem of dynamic survivable lightpath provisioning against single node/link failures in optical mesh networks employing wavelength-division multiplexing (WDM). This paper present a new approach to provisioning... [11 Jul 2008]
Efficient Bandwidth Guaranteed Restoration Algorithms for Multicast Connections
White Paper This paper defines a new restoration strategy for provisioning bandwidth guaranteed recovery for multicast connections in presence of link failures. The new restoration strategy is formulated into a new Integer Linear Programming (ILP) algorithm... [11 Jul 2008]
A Heuristic Routing Algorithm for Shared Protection in Connection-Oriented Network
White Paper In a connection-oriented network, shared protection provides the same level of protection against single path failures as dedicated protection, with potentially higher network utilization. This paper lists the requirements of path protection and... [11 Jul 2008]
Fault Restoration Techniques for MPLS With QoS Constraints
White Paper This paper investigates distributed fault restoration protocols for MultiProtocol Label Switching (MPLS) that automatically reroute label switched paths in the event of failures while maintaining Quality of Service (QoS) requirements. [11 Jul 2008]
Shared Protection Routing Algorithm for Optical Network
White Paper In a connection-oriented network such as an all-optical transport network, shared protection provides the same level of protection against single path failures as dedicated protection, with potentially higher network utilization. [11 Jul 2008]
Local Detection and Recovery From Multi-Failure Patterns in MPLS-TE Networks
White Paper When the network is subject to multiple element failures, it becomes challenging to handle all the possible failure scenarios, for they are more disruptive and may require many more bypass tunnels to be dealt with. [11 Jul 2008]
