Two models for the Signalling Connection  Control Part (SCCP) SS7 protocol layer incorporating GTT are developed . The two models  reflect two different possible GTI implementations within the SCCP protocol layer. The models  are based on a generic approach to modelling SS7 protocol layers. Mathematical analysis has  been done using general M/Gl/ 1 priority queuing models with feedback. Selected equations from  the mathematical analysis are verified against simulation.  Several quantitative conclusions relating to the performance of SS? networks are drawn  from the results. Results show that the location of the GTI function within the SS7 network  effects the performance of the network significantly. The effect of introducing GTI also causes  a significant degradation in the performance of the Message Transfer Part (MTP). These results  and others are useful for serving as general considerations for SS? network design and planning.  Moreover, the work done can be extended to higher layer SS7 protocols (such as the Transaction  Capabilities Application Part) and used to undertake performance evaluation of other services  provided by the SS? network.  0aSignal theory (Telecommunication)1 aSharma, A.B.,eChairperson1 aMurch, Alan,eExamination committee1 aErke, Tapio J.,eExamination Committee1 aTakahashi, K.,eExamination committee2 aNokia Telecommunications,eScholarship donor2 aAsian Institute of Technology.tThesis ;vno.
