摘要: A service description may be used in network virtualization in order to specify requirements of an application. In order to provide network virtualization for generic networking components, including legacy networking components, the service description is mapped to a logical network implementation and then subsequently mapped to a physical implementation.
摘要翻译: 网络虚拟化中可以使用服务描述来指定应用程序的要求。 为了为通用网络组件(包括传统网络组件)提供网络虚拟化,将服务描述映射到逻辑网络实现,然后映射到物理实现。

摘要: The devices, systems, and methods test network connectivity, where the physical network is used to provide one or more service chains connecting service appliances, including firewalls, intrusion detection systems, load balancers, network address translators, web servers, and so on. A service chain may involve multiple routing paths. The devices, systems, and methods test network connectivity test network connectivity by injecting customized echo request packets on each routing path and collecting customized echo reply packets in response. The customized echo reply packets are processed and aggregated to isolate network connectivity problems.

摘要: Routers using virtual routing and forwarding nodes to implement a service fabric of service chains. The router may configure M+1 virtual routing and forwarding instances, M being an integer representing a number of a plurality of service appliances in a data center network. Each virtual routing and forwarding instance may be associated with a routing table of routing rules to define various service chain routing paths. The routing rules are based on destination addresses in data packets.
