.... are performed (as discussed in Section IVA) 2) limitations on the number of nodes (or links) generating update information, and (3) aggregation of state information for scalability (as discussed in Section IV C) A number of studies analyze the impact of inaccurate information on routing [44] [57]. These studies reveal three interesting results. First, the effect of inaccuracies is minimal if only bandwidth requirements are given. Second, inaccuracies can have a high impact on end to end delay requirements, and the path selection problem then becomes intractable. Two models are studied for ....
....Scalability Hop by hop QoS aware Multicast Routing Protocol (QMRP) 51] Hierarchical Partitioning QoS requirements [48] the observed flow blocking probability. C. Scalability and Routing Cost Implementation and deployment costs of CBR include both computational cost and protocol overhead [57], 6] The computational cost can be offset by the evolution of technology, i.e. faster processors and larger storage. In contrast, protocol overhead is not easily contained, because it affects several parameters, such as available link bandwidth and storage. The main factors affecting the ....

....results show the benefits of the proposed framework, which guarantees better performance compared to the classic static routing algorithms used in today s networks. I. INTRODUCTION Research on Quality of Service (QoS) routing in the Internet was extremely active in recent years [1] 2] 3] [4], 5] Most of the research focused on algorithmic aspects, trying to find suitable metrics to exploit dynamic traffic conditions and improve performance with respect to the simple Shortest Path ( algorithm, which is presently used in the Internet [6] 7] as Interior Gateway Protocol (IGP) ....

....to maintain the state information, routing algorithms re quire routers to exchange state information. The manner in which this is accomplished can be diverse ranging from periodic updates to triggered updates. Sending updates at very large intervals has been shown to adversely affect performance [12, 13]. Our simulation results also confirm this observation. However, sending excessively frequent updates is also infeasible due to the routing overhead. A triggered update is a possible alternative, whereby updates are triggerred only when there is a significant change in network state. For example, ....

....ATM) One of the key issues in the design of such services is how to identify a feasible route that satisfies multiple constraints (e.g. bandwidth, delay, jitter) while simultaneously achieving efficient utilization of network resources. This problem is known as QoS (or constraint based) routing [1], 2] 3] 4] 5] 6] Its relevance is justified for both reservation based services (e.g. Intserv, MPLS, ATM) as well as reservationless services (e.g. Diffserv) For example, in the ATM PNNI protocol [7] constraint based routing is performed by source nodes to determine suitable paths ....
