For example,the maintenance of multiple networks can require additional staff.often,this staff must be trained on multiple vendor technologies,sometimes requiring parallel groups specializing in each （72） hence,additional maintenance procedures must be maintained and administrative records are （73） the duplication of trasport facilities to carry （74） network traffic is an inefficient use of resources and,not surprisingly,more technologies installed in a central office mean the necessity for more physical space,and an increase in power connections and power consumption.migration of these （75） network elements to IP-based DCns is alogical strategy

例如，维护多个网络需要增加工作人员。通常这些人员必须培训，以便熟悉多种制造商技术，同时还需要熟悉不同平台的许多工作小组。因此，额外增加的维护过程使得各种管理记录激增。承载着不同网络通信的多种传输设施造成了资源的无效使用。很自然的推论就是，更多的技术装置配备在交换局中意味着需要更大的物理空间，增加了动力设备和电源消耗。这些遗产网络元素逐步迁移到基于IP的DCN是符合逻辑的策略。

覆盖路由网络中数据转发的方法属于覆盖网络中的路由和转发技术领域，其特征在于：通过在现有底层网络中部署覆盖网络路由节点形成覆盖路由网络，为接入的用户主机之间提供完全透明的覆盖路由和数据转发服务，在数据转发过程中，用户的IP分组被封装、转发、解封装，最终发送到目的主机，实验表明在较小规模的覆盖路由网络的全连接拓扑里，同时使用跳数受限机制寻找到的路由路径会比Internet路由性能更高，而且底层网络出现故障时，覆盖路由网络能迅速绕过故障区域，从而提高了端到端的传输性能。
