This paper focuses on the research and design of a BGP / MPLS VPN experiment system, which is based on high-layer virtual switch technology and MPLS network infrastructure, supporting large-scale multi-user subsequent control, real-time interaction and central management. 基于高层虚拟交换技术,采用了MPLS网络基础架构,研究并设计了一种支持大规模多用户并发控制,能进行实时交互及集中管理功能的BGP/MPLSVPN实验系统。
Network virtualization allows multiple heterogeneous virtual networks to coexist over a shared substrate network infrastructure, which enables the deployment of new network architectures, protocols, and applications without affecting the existing network service and thus make network innovations easier. 网络虚拟化允许在共享的底层物理网络基础设施之上共存多重异构的虚拟网络,使在不影响现有网络服务的前提下部署新的网络架构、协议以及应用成为可能,从而有效地支持网络技术创新。
Setting up an virtual network requires little modification of the customer's data center network infrastructure. 构建虚拟网络几乎不需修改用户的数据中心基础架构。
Virtual networks are those network systems which depend upon the delivery capability provided by the Internet infrastructure but are independent of the Internet in both topology and information forwarding rules. 虚拟网络是依赖Internet基础设施所提供的传输能力而存在、但又具有独立拓扑结构和信息传递规则的网络系统,它是今天Internet结构和功能的组成部分。
