    • Embodiments of the present disclosure may include methods, systems, and computer readable media with executable instructions. An example method for network virtualization can include providing, by a datacenter (100) having physical and/or virtual resources, a number of virtual tenant datacenters (tDatacenters), each tDatacenter being isolated from other tDatacenters. A tenant virtual local area network (T-VLAN) (226, 228, 682) is associated to each of the number of tDatacenters, and a value of an end-to-end invariant network virtual local area network (VLAN) identification (VID) label (T-VID) is associated to a particular T-VLAN (226, 228, 682). A network packet associated with the particular T-VLAN (226, 228, 682) is modified at an edge network boundary (561) to include the T-VID. The T-VID is configured to have more than 4096 possible values.
    • 本公开的实施例可以包括具有可执行指令的方法,系统和计算机可读介质。 用于网络虚拟化的示例性方法可以包括由具有物理和/或虚拟资源的数据中心(100)提供多个虚拟租户数据中心(tDatacenters),每个tD中心与其他tDatacenters隔离。 租户虚拟局域网(T-VLAN)(226,228,682)与多个tDatacenters中的每一个相关联,并且端到端不变网络虚拟局域网(VLAN)标识(VID)的值 )标签(T-VID)与特定的T-VLAN(226,228,682)相关联。 与特定T-VLAN(226,228,682)相关联的网络分组在边缘网络边界(561)被修改为包括T-VID。 T-VID配置为具有超过4096个可能的值。

    • In a method for maintaining virtual network context across multiple infrastructures, a data packet having a virtual network identifier in a first routing infrastructure is accessed, wherein the virtual network identifier indicates a tenant network. The data packet is encapsulated for transport of the data packet through a second routing infrastructure. In addition, the virtual network identifier is inserted into the encapsulation of the data packet for routing of the data packet through the second routing infrastructure while maintaining virtual network context and identification between the first routing infrastructure and the second routing infrastructure, wherein the first routing infrastructure operates under a first virtual networking technology and the second routing infrastructure operates under a second virtual networking technology.
    • 在跨多个基础设施维护虚拟网络上下文的方法中,访问在第一路由基础设施中具有虚拟网络标识符的数据分组,其中所述虚拟网络标识符指示租户网络。 数据分组被封装以通过第二路由基础设施传输数据分组。 另外,虚拟网络标识符被插入到数据包的封装中,用于通过第二路由基础设施路由数据包,同时保持第一路由基础设施和第二路由基础设施之间的虚拟网络上下文和标识,其中第一路由基础设施 在第一虚拟网络技术下运行,第二路由基础架构在第二虚拟网络技术下运行。
