Performance comparison of bandwidth allocation mechanisms for LAN/MAN interworking through an ATM network
K. Shimokoshi · 2002
LAN/MAN interconnection through ATM networks has attracted attention as an application in the first stage of the B-ISDN era. The interworking methods for connectionless (CL) data transfer through an ATM based B-ISDN, which can be applied both for (i) indirect, implicit service and (ii) direct, explicit service, are evaluated. The paper offers a quantitative assessment on some major algorithms used to effectively allocate the network resources to the CL traffic. A performance comparison of six bandwidth allocation methods based on the BR (bandwidth renegotiation), VCE (virtual connections establishment) and FBA (fixed bandwidth allocation) which are combined with TEF (traffic enforcement function) mechanisms is given by a simulation approach.>
