Description
Summary:One of the important considerations for discarding cells is to guarantee the quality of service (QoS) of each virtual channel connections (VCCs) in ATM networks. The wasted volume of network resources due to discarding cells should be, however, considered as another major criterion in the design of an effective cell discard scheme. From the viewpoint of such volume, this paper develops a novel cell discard scheme: the "forwarding-strength-based" one, which can minimize the average lost (i.e., wasted) volume of network resources due to cell discarding. First the definition of forwarding strength /spl delta/, then the /spl delta/ cell discard scheme and finally the performance analysis of the proposed scheme on the average lost volume of network resources and the cell lost probability are described respectively. In the case that a dynamic monitor of CLR-QoS is accommodated, the CLR-QoS of each VCC can be guaranteed under the proposed /spl delta/ cell discard scheme.
