0.前言在交换机的日常维护的工作中很少能到七号信令中的路由选择及链路选择域的应用,但如果进行信念网负荷统计时,发现某些端局到信令转接点的组内负荷及组间负荷严重不均,在进行信令网优化时,就有必要了解一些日常很少接触的路由选择及链路选择域的相关知识了。1.MTP负荷分担原理(1)业务消息在MTP部分的负荷分担,主要取决于利用消息的SLS来计算消息出局路由和链路的算法。对于编路到某目的信令点的消息而言,如果算法正确灵活,则能根据SLS变化有规律地将所有消息均

However, when carrying out the belief network load statistics, it is found that some of the end-to-end signaling transfer Point load within the group and the group between the load of serious uneven, in the optimization of the signaling network, it is necessary to understand some day-to-day contact with the routing and link selection domain knowledge. I. Load balancing principle of MTP 1) The load sharing of service messages in the MTP part mainly depends on the algorithm that uses the message SLS to calculate the outgoing routes and links of the messages. For messages routed to a destination signaling point, if the algorithm is correct and flexible, all messages can be regularly changed according to SLS changes
