3G业务开展以来,MSTP系统对高速率分组域业务的承载给各地区本地骨干汇聚层传输网络带来了巨大的带宽压力,分组域业务数量的增加及带宽的增长,将对各地区本地骨干汇聚层传输网络造成更大的冲击,导致骨干汇聚层传输网络更大的调整,更合理的利用现有网络资源也成为通信网络现阶段优化的重点。因此,合理利用现有设备和电路资源,增强现有传输网络网络的可扩展性,缓解骨干汇聚层传输网络的承载压力,已成为现阶段各运营商关注的重点问题。
Since the launch of 3G services, the MSTP system has brought huge bandwidth pressure to high-rate packet-based services to local backbone convergence network transmission networks. The increase of the number of packet-based services and the increase of bandwidth will result in the convergence of local backbone convergence Layer transmission network to cause greater impact, leading to a greater convergence of the backbone aggregation layer transmission network, more rational use of existing network resources has become the focus of communication network optimization at this stage. Therefore, rational utilization of existing equipment and circuit resources to enhance the scalability of the existing transmission network network and alleviate the pressure on the backbone aggregation transmission network has become a key issue of concern to all operators at this stage.
