ATM NETWORK RESOURCE-MANAGEMENT TECHNIQUES FOR CBR VIRTUAL PATHS CHANNELS/

The benefits of ATM techniques have been widely recognized and many or ganizations envisage the introduction of ATM techniques into their tel ecommunication networks. The ATM benefits can, however, be fully explo ited only after effective network resource management techniques have been developed. This paper focuses on CBR-VP management techniques. Th e ATM transport network architecture and VP roles are summarized. Next , the issues of VP accommodation design are described. The point is ho w to create a design that accommodates cell loss and cell delay jitter , both of which depend on various network parameters and conditions. F or this purpose, analytical procedures based on an M/D/1 queueing mode l are adopted. The approximation method is shown to be very effective in practical use through computer analysis. The method guarantees cons ervative QOSs. Finally, the proposed method is applied to several desi gn examples to illustrate VP management issues. The proposed method wi ll enable ATM techniques to be introduced to our telecommunication net works by the mid-1990's.
