分组交换方式

基于S-mesh系统结构中，其片上通信网络采用电路交换方式，而处于网络外部边缘设备如资源节点则采用报文分组交换方式。

In the S-mesh system , the kernel communication network adopts circuit switching mode , and the edge devices , such as resource nodes , adopt the packet switching mode .

CP层的功能包括：用集中器功能减少对CS网的呼叫，在最小电路集合基础上控制电路集合的动态增减，采用分组交换方式复用每一条物理电路等。

The functions of the CP layer are intended to reduce calls for CS network by means of concentrator , to control dynamic change of circuit set on the basis of minimum circuit set and to multiplex each physical circuit by the application of PS technique .

VolP由于其分组交换方式及实时性特点，不能保证分组的可靠传输。

Because of adopting grouping exchange , it cannot ensure the accuracy of transmission in VolE .

分组交换话音通信方式在经济上和技术上均有明显的好处。
