According to the analysis of mobile data services, it is found that terminal has become the bottleneck of service interconnection.

For the purpose to improve the efficiency of VC channel during the IP service loading and simplify the signalling load, this paper developed a synchronization route algorithm for IP payload in I PNNI systems.

In order to make full use of the available bandwidth of DTV services to transmit the best-effort IP service, the issue of dynamic bandwidth allocation between DTV and IP services was discussed.

Taking the dominant position of IP services and development of optical transmission technology into consideration,in order to adapt the requirements for future development, there is not only need to improve link capacity and network utilization,but also need to promote the intellige.

According to IP data service current situation, shallow to discuss IP data service odd ways that business insert and analyze the existing problem, put forward, utilize MSTP apparatus build of future generation IP datum construction step and group network scheme that business insert, then IP data service and TDM service at the same time and build the concept hierarchically.
