【摘要】：建设支撑企业网业务的多业务承载网,满足企业网的数据中心发展战略要求和布局,实现广域网线路资源整合,支持新一代系统的快速投产、语音视频的分布式部署,灵活扩展业务布局等需求。本期工程项目实施覆盖企业网建设,包括企业网一期三个核心节点的建设,以及两个数据中心、一个试点业务中心和两个试点分部至企业网的接入迁移工作。企业网采用的关键设备和模块要求运行稳定、故障率低,具有较长的平均无故障工作时间和良好的可维护性。企业网架构在连接方式、数量、性能、容量等方面要有冗余设计,尽可能减少单点故障点的数量及故障恢复时间,采用“轻载”的容量规划,满足上层业务系统不间断的连接需求。贯彻“松散耦合”的整体设计思想,建设层次化、模块化、可扩展的企业网架构。企业网在大负荷、大流量的压力下,能连续、稳定运行,而且不降低整体性能。应用策略控制和网络多重服务尽量在接入网来实现。保持网络的逻辑分层结构不变的构想,搭建测试网络环境,并结合将来的实际网络结构进行大量的与VPC虚拟以太通道技术、FEX板卡延伸技术、防火墙PBR及架构性能相关的测试,为今后新一代网络项目的的建设、实施、运维提供宝贵的经验,打下良好的基础。
[Abstract]:The multi - service bearer network supporting enterprise network service is constructed to meet the data center development strategy requirements and layout of the enterprise network , realize the integration of the WAN line resources , support the rapid production of the next generation system , the distributed deployment of the voice video , the flexible expansion service layout and the like . The project implementation covers the construction of the enterprise network , including the construction of the three core nodes of the enterprise network , and the access and migration of the two data centers , a pilot service center and the two pilot branches to the enterprise network .

The key equipment and modules adopted by the enterprise network require stable operation , low failure rate , long average no - failure working time and good maintainability . The enterprise network architecture can reduce the number of single point failure points and the failure recovery time , and can reduce the number of single point failure points and the failure recovery time . The enterprise network structure can continuously and stably operate under the pressure of large load and large flow , and can not reduce the overall performance .

Keeping the logic hierarchy of the network unchanged , building a test network environment , and combining with the actual network structure in the future , a large number of tests related to the VPC virtual Ethernet channel technology , the card extension technology , the firewall PBR and the architecture performance are carried out , so as to provide valuable experience for the construction , implementation and operation and maintenance of the next generation network project , and lay a good foundation .
