Signalling is the critical component of telecommunications networks. Thus the design of the signalling system is a fundamental issue for the creation of the future Broadband ISDN out of ATM switching technology. Today's telecommunication networks use common channel signalling networks (standardised in SS7) which are often separate from the bearer or transport network. With an ATM based Broadband ISDN (B-ISDN), it is anticipated that both signalHng and user traffic will share the underlying ATM layer. An SS7 "Message Transfer Part" (MTP) provides reliable connectionless signalling message transport. However due to differences between SS7 links and ATM signalling links (i.e. ATM Virtual Channel Connections (VCCs)), a new MTP will be needed for B-ISDN. This thesis is concerned with the design and engineering of the B-ISDN MTP The need for an ATM signalling link error monitor is identified as a key requirement. To design such an error monitor, the delay performance of ATM signalling links during errored periods must be determined. This requires a model for the delay performance of the Service Specific Connection Oriented Protocol (SSCOP), the link level protocol to be used on ATM signalling links. The thesis presents an SSCOP delay model, which also gives general results for mean Selective Repeat transmitter delay and the mean (and distribution) of Selective Repeat receiver delay.
