摘要： Multiple TCP/IP stack processors on a host. The multiple TCP/IP stack processors are provided independently of TCP/IP stack processors implemented by virtual machines on the host. The TCP/IP stack processors provide multiple different default gateway addresses for use with multiple processes. The default gateway addresses allow a service to communicate across an L3 network. Processes outside of virtual machines that utilize the TCP/IP stack processor on a first host can benefit from using their own gateway, and communicate with their peer process on a second host, regardless of whether the second host is located within the same subnet or a different subnet. The multiple TCP/IP stack processors can use separately allocated resources. Separate TCP/IP stack processors can be provided for each of multiple tenants on the host. Separate loopback interfaces of multiple TCP/IP stack processors can be used to create separate containment for separate sets of processes on a host.

摘要： For a managed network including multiple host machines implementing multiple logical networks, some embodiments provide a method that reduces the memory and traffic load required to implement the multiple logical networks. The method generates configuration data for each of multiple host machines including (i) data to configure a host machine to implement a set of logical forwarding elements that belong to a set of routing domains and (ii) identifiers for each routing domain in the set of routing domains. The method then receives data regarding tunnels endpoints operating on each of the host machines and an association with the routing identifiers sent to the host machines. The method then generates a routing domain tunnel endpoint list for each routing domain based on the data received from each of the host machines including a list of the tunnel endpoints associated with the routing domain which the host machines can use to facilitate packet processing.

摘要翻译：主机上有多个TCP / IP堆栈处理器。多个TCP / IP堆栈处理器独立于由主机上的虚拟机实现的TCP / IP堆栈处理器提供。 TCP / IP堆栈处理器提供多种不同的默认网关地址，可用于多个进程。默认网关地址允许服务通过L3网络进行通信。在第一主机上利用TCP / IP堆栈处理器的虚拟机之外的进程可以受益于使用自己的网关，并且在第二主机上与其对等进程通信，而不管第二主机是位于同一子网内还是不同的子网。多个TCP / IP堆栈处理器可以使用单独分配的资源。可以为主机上的多个租户中的每一个提供单独的TCP / IP堆栈处理器。可以使用多个TCP / IP堆栈处理器的独立回送接口为主机上的单独进程集创建单独的包含。

摘要： A method of defining a virtual network across a plurality of physical hosts is provided. At least two hosts utilize network virtualization software provided by two different vendors. Each host hosts a set of data compute nodes (DCNs) for one or more tenants. The method, at an agent at a host, receives a command from a network controller, the command includes (i) an identification a resource on a tenant logical network and (ii) an action to perform on the identified resource. The method, at the agent, determines the network virtualization software utilized by the host. The method, at the agent, translates the received action into a set of configuration commands compatible with the network virtualization software utilized by the host. The method sends the configuration commands to a network configuration interface on the host to perform the action on the identified resource.
