Ethernet has spread its territory into metro and backbone networks. Since spanning tree protocol (STP) is impractical for backbone networks routing, many spanning tree based Layer 2 routing schemes have been proposed, such as multiple spanning tree protocol (MSTP) and MSTP based shortest path bridging (MSTP-SPB). We have developed three analytical models for evaluating these routing schemes, but they...

Ethernet is a de factor standard in LAN and now has spread its territory into backbone networks. To get better performance in there, many spanning tree based routing standards or protocols have been proposed, such as multiple spanning tree protocol(MSTP) and the shortest path bridging(SPB). This paper focuses on the SPB routing, and introduces EDSPB that applies the Euclidean distance into SPB. Euclidean...
Ethernet recently begins to be used in backbone networks. To get better performance in there, many layer-2 spanning tree based Ethernet routing schemes have been proposed, such as spanning tree protocol(STP), multiple spanning tree protocol(MSTP), shortest path routing(SPB) and a special backbone routing scheme called ENDIST. We deal with analytic models that can analyze and compare these routing...
Wireless sensor network (WSN) is a wireless network that gathers information from remote area with autonomously configured routing path. We propose a fusion based routing for converge cast in which all sensors periodically forward collected data to a base station. Previous researches dealt with only full-fusion or no-fusion case. Our fusion rate based spanning tree (FST) can provide effective routing...
Many routing topologies have been proposed to extend lifetime of ubiquitous sensor network (USN) consisting of sensor nodes with limited energy. If measurement data is collected periodically for every nodes and perfect fusion during data aggregation, minimum spanning tree (MST) and chains have been two major topologies. MST minimizes total transmission energy and chain consumes energy very evenly...
Carrier Ethernet integrates distributed layer-2 bridge networks to a backbone network. Since carrier Ethernets use simple layer-2 routing, its performance is lower than that of layer-3 routing methods. We introduce an analytic model that evaluates the routing methods in backbone networks. The model solves the multi- input and multi-output maximum flow problem in backbone networks using linear programming...
Carrier Ethernet integrates distributed layer-2 bridged networks to a backbone network. Currently, Carrier Ethernet uses multiple spanning tree protocol (MSTP) that allows multiple spanning trees. Shortest path bridging (SPB) based on MSTP is expected to be a major routing scheme in coming era because SPB is simple and shows better performance. These layer-2 routing protocols are built on spanning...
The Border Gateway Protocol (BGP)[1] is a unique routing protocol in broadband Internet. It chooses routing paths considering Internet hierarchy and local policies. In BGP connectivity by way of a series of links between source and destination nodes does not mean reachability between the two. At emergency when BGP routers or links over wide range are not available, BGP routers have to use links that...
