analysis of Topology aggregation techniques for qos Routing
ACM Computing Surveys, 2007Co-Authors: Suleyman Uludag, Kingshan Lui, Klara Nahrstedt, G B BrewsterAbstract:We study and compare Topology aggregation techniques used in QoS Routing. Topology Aggregation (TA) is defined as a set of techniques that abstract or summarize the state information about the network Topology to be exchanged, processed, and maintained by network nodes for Routing purposes. Due to scalability, aggregation techniques have been an integral part of some Routing protocols. However, TA has not been studied extensively except in a rather limited context. With the continuing growth of the Internet, scalability issues of QoS Routing have been gaining importance. Therefore, we survey the current TA techniques, provide methodology to classify, evaluate, and compare their complexities and efficiencies.

ICOIN (1) - A Router Assisting Control Tree Configuration Mechanism for Reliable Multicast
Information Networking: Wired Communications and Management, 2002Co-Authors: Eunsook Kim, Shin-gak Kang, Seok Joo Koh, Juyoung Park, Jongwon ChoeAbstract:For reliable multicast service, the mechanism based on hierarchical control tree can be a promising solution to avoid well-known feedback implosion. However, configuration of an efficient control tree is very difficult for IP Multicast because it does not provide explicit membership and Routing Topology information to upper layer protocol. If the transport layer tree and the network layer tree are very different, it may take large cost to handle control messages. Especially, when a node at a downstream link of the network Routing tree becomes a parent node of an upstream link at the control tree of transport layer, the discrepancy between Routing tree and control tree causes to waste network resources by redundant messages. This problem can be solved if router that knows the information on Routing Topology can support configuration of a control tree and reliable delivery. However, the change of router function embraces deployment problem. Thus, this paper proposed a very simple method of router assist to minimize change of router functions. With this method, routers are only required to recognize message types of control messages in order to forward the messages to correct direction: upstream or downstream.

A router-assisted session tree configuration mechanism for reliable multicast
IEEE Communications Letters, 2002Co-Authors: Eunsook Kim, Shin-gak Kang, Jongwon ChoeAbstract:A session tree based mechanism provides an efficient method to avoid well-known feedback implosion. However, it is not easy to configure an efficient session tree for IP multicast because it does not provide any explicit membership and Routing Topology information to the upper layer protocol. Incongruity between a session tree built on the transport layer and the corresponding Routing tree on the network layer would incur large cost to handle control messages. This problem can be solved if a router that knows the information of Routing Topology can support the configuration of a session tree. Thus this letter proposed a router-assistant mechanism which minimizes the change of router functions and allows the routers to assist in providing a reliable multicast transport service.

A session tree creation mechanism with router assist for reliable multicast
5th IEEE International Conference on High Speed Networks and Multimedia Communication (Cat. No.02EX612), 1Co-Authors: Eunsook Kim, Shin-gak Kang, Jongwon ChoeAbstract:For reliable multicast service, the hierarchical control tree based mechanism can be a promising solution to avoid the well-known feedback implosion. To configure a logical tree is difficult because IP multicast does not provide explicit membership and Routing Topology information to upper layer protocols. Because of this problem, the transport layer tree may not be congruent with the underlying Routing tree, and in this case, reliable multicast services may incur a large cost. This problem can be solved if the router that knows that the Routing Topology can support configuration of a control tree and reliable delivery. Thus, this paper proposes a router-assist mechanism which uses very simple methods to allow the routers to assist in providing a reliable multicast transport service.
