帧中继业务是在用户与网络接口之间提供用户信息流的双向传送,并保持信息顺序不变的一种承载业务。用户信息以帧为单位进行传输,并对用户信息流进行统计复用。它有着传输时延小、速率高、网络处理简单、组网简单、一个端口可实现多个永久虚电路(Permanent Virtual Circuit,PVC)的连续、能和不同入网速率的用户通信的特点,所以在企业、行业、政府部门总部和各地分支机构的局域网之间互联的应用非常广泛。在使用过程中遇到了一些问题,下面笔者就如何诊断、排除帧中继故障做一些介绍,供网络管理人员参考。
Frame relay service is to provide two-way transmission of user information flow between user and network interface, and to maintain a sequence of information bearer service. User information is transmitted in frame units and is statistically multiplexed with user traffic. It has the advantages of small transmission delay, high speed, simple network processing and simple networking. One port can implement continuous, permanent virtual circuit (PVC) communication with users with different network access rates. Therefore, Enterprises, industries, government departments and branches around the local area network interconnection is widely used. In the course of the use of some problems encountered, the author on how to diagnose the following, to exclude some troubleshooting frame relay, for network management reference.
