Virtual Path Assignment and Virtual Circuit Routing in ATM Networks
The use of virtual paths in ATM networks reduces the call set-up delays, simplifies the hardware in the transit nodes and provides simple virtual circuit admission control. However, it also reduces the degree of capacity sharing and thus, increases the call blocking rate. We consider the following problem: given a network topology, link capacity of each physical link and traffic requirement of ...
متن کاملDirected Virtual Path Layouts in ATM Networks
Motivated by Asynchronous Transfer Mode (ATM) in telecommunication networks, we investigate the problem of designing a directed virtual topology on a directed physical topology, which consists in nding a set of directed virtual paths (VPs) satisfying some constraints in terms of load (the number of VPs sharing a physical link) and hop count (the number of VPs used to establish a connection). Fo...
متن کاملRouting in Virtual Path Based ATM Networks
We consider the issue of routing requests for virtual circuits in a Virtual Path (VP) based ATM network. We suppose that the VPs are partitioned in a manner such that all the VCs making use of any given VP have the same traac characteristics and quality of service demands. A virtual circuit request can be accepted in the network only if the speciied loss and delay bounds can be guaranteed for t...
متن کاملVirtual Path Management in ATM Networks
In ATM networks, VPCs (Virtual Path Connections) could be setup permanently or semi-permanently by network administrators to form a virtual private network or temporarily by applications to group several VCCs (Virtual Channel Connections) of users. Virtual path management is of great importance in maintaining ATM network service quality. In this paper, we propose our heuristics for three proble...
متن کاملVirtual Path Layouts in ATM Networks
We study virtual path layouts in a very popular type of fast interconnection networks, namely ATM networks. One of the main problems in such networks is to construct path layout that minimizes the hop-number (i.e. the number of virtual paths between any two nodes) as a function of edge congestion (i.e. the number of virtual paths going through a link). In this paper we construct for any n verte...
