RSS link meshA Network Management Architecture for Robust Packet Routing in Mesh Optical Access Networks
White Paper The architecture can be utilized with an arbitrary, link-redundant mesh network (node-redundancy is necessary only to handle all node failures), and assumes neither the use of a star topology nor the ability to embed such a topology within the... [18 Jul 2008]
Improving Restoration Success in Mesh Optical Networks
White Paper In shared mesh restoration, a distributed signaling protocol is used to reroute connections from failed service paths to restoration paths upon failure events. However, even when the network contains sufficient capacity, the restoration paths could... [18 Jul 2008]
A Review of Traffic Grooming in WDM Optical Networks: Architectures and Challenges
White Paper This paper reviews most of the recent research work on traffic grooming in WDM ring and mesh networks. The transmission capacity of a link in today's optical networks has increased significantly due to Wavelength-Division Multiplexing (WDM... [18 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]
On Direct Routing in the Valiant Load-Balancing Architecture
White Paper To interconnect N nodes of capacity r, the VLB architecture requires a logical full mesh of link capacity c = 2r/N. It is very hard to design a network with performance guarantees, partly because it is hard to estimate the future traffic matrix. [10 Jul 2008]
The Bi-Mesh Survivable Network - Fast Recovery From Node Failure in MPLS Enabled Networks
White Paper To provide reliable carrier-grade service, MPLS-based recovery procedures must be able to quickly address any link or node failure. Today's converged networks are increasingly based on MPLS technology. [04 Jul 2008]
Internet Traffic Engineering without Full Mesh Overlaying
White Paper This paper proposes a new approach, which we call the integrated approach, to achieve traffic engineering without full-mesh overlaying. Traffic engineering objectives are realized by setting appropriate link metrics in IP routing protocols. [03 Jul 2008]
Network Monitoring: It Depends on Your Points of View
White Paper End-to-end active network monitoring infers network characteristics by sending and collecting probe packets from the network edge, while probes traverse the network through multicast trees or a mesh of unicast paths. [04 Mar 2008]
Understanding Interference and Carrier Sensing in Wireless Mesh Networks
White Paper This paper analyzes the carrier sensing and interference relations between two wireless links and measure the impact of these relations on link capacity on an indoor 802.11a mesh network testbed. The paper shows that asymmetric carrier sensing and... [15 Feb 2008]
Performance of TCP/UDP Under Ad Hoc IEEE802.11
White Paper Two topologies are used, a string and a mesh topology. Although there have been many attempts to measure and analyze the performance of the TCP protocol in wireless networks, very few research was done on the UDP or the interaction between TCP and... [07 Nov 2007]
Routing Stability in Static Wireless Mesh Networks
White Paper To conduct these case studies, it collected detailed link quality information over several days from each of these networks. Considerable research has focused on the design of routing protocols for wireless multi-hop networks. [03 Sep 2007]
High-Throughput Multicast Routing Metrics in Wireless Mesh Networks
White Paper The stationary nature of nodes in a mesh network has shifted the main design goal of routing protocols from maintaining connectivity between source and destination nodes to finding high-throughput paths between them. [31 Aug 2007]
Low Latency Multimedia Broadcast in Multi-Rate Wireless Meshes
White Paper This paper considers a novel type of multi-rate mesh networks where a node can dynamically adjust its link layer multicast rates to its neighbours. In a multi-rate wireless network, a node can dynamically adjust its link transmission rate by... [25 Aug 2007]
Multipath Routing in Wireless Mesh Networks
White Paper In a mobile ad hoc network, link lifetimes may be relatively short compared to traffic flows. This paper addresses multipath routing in a mobile wireless network. The paper reviews the premise that a routing protocol should prefer disjoint path... [23 Aug 2007]
High-Throughput Multicast Routing Metrics in Wireless Mesh Networks
White Paper The stationary nature of nodes in a mesh network has shifted the main design goal of routing protocols from maintaining connectivity between source and destination nodes to finding high-throughput paths between them. [10 Aug 2007]
