【摘要】 传输网络作为各综合业务的承载平台,其网络规划的好坏直接影响到各种业务的发展。为了适应未来多业务发展特别是3G业务的需求,需要对现有的传输网进行改造。为了配合3G网络的建设和新的业务网络的要求,考虑调整网络结构和引入网络新技术来进行网络的建设,并将网络的安全性作为网络建设改造的一个重要因素和网络建设目标来进行网络优化和调整,逐步引入新的技术手段和新的网络组织方式,以保证网络的灵活性、扩展性和安全性。双平面双节点改造是指在原有传输网络的基础上,建立以10Gbit/s光速率传输的骨干环,并且汇聚层、接入层分别跨两个不同站点进行连接。以满足预期的传输电路需求为目的,综合考虑网络的可靠性、可持续发展能力及工程成本等因素,对传输网络的未来建设作出一个合理的安排和估计。更多还原

【Abstract】 The goodness and badness of network plan of transmission network as the platform of every synthetical business bearing the weight of direct impact to development of various business. We need to reform the now available transmission net to adapting to various business especially 3G business.For the network construction coordinating 3G and the new business network request,consider the adjusting of network construction and lead into new technique, and consider the network security as a key factor.Lead into new technology means and new network organization way step by step, to ensure the network flexibility, expands nature and security. The double nodes and double surfaces reform is on the basis of the original transmission network, building the backbone net which the transfers rate with 10 Gbit/s, and converging switching in a tier, striding over different two stations respectively carries out connection. Considering the factors such as network reliability, capability of sustainable development and project costs synthetically, We make a rational arrangement and estimating to the future of transmission network.更多还原
