摘要： Some embodiments provide a distributed control system for controlling managed switching elements of a network. The distributed control system comprises a first controller for converting a first set of input logical control plane data to a first set of output logical forwarding plane data. It also includes a second controller for converting a second set of input logical control plane data to a second set of output logical forwarding plane data.

摘要： Processing packet information using an array of processing elements involves performing search-independent processing on packet information in parallel with a search of a first stage memory unit and then using the processed information and the result from the search of the first stage memory unit to generate search information for a search of a second stage memory unit. The search-independent processing of packet information in parallel with search operations can be repeated at each stage of the array. By performing search-independent processing of packet information in parallel with search operations instead of serially, latency that is contributed from the relatively slow search operations is reduced.
摘要翻译：使用处理单元阵列处理分组信息涉及对第一级存储器单元的搜索并行地对分组信息进行搜索独立处理，然后使用经处理的信息和来自第一级存储器单元的搜索的结果来生成搜索用于搜索第二级存储器单元的信息。与搜索操作并行的分组信息的搜索独立处理可以在阵列的每个阶段重复。通过与搜索操作并行地执行分组信息的搜索独立处理而不是串行地执行，从相对较慢的搜索操作中贡献的等待时间减少。

摘要： A network control system that includes several controllers for managing several switching elements. Each controller includes a network information base (NIB) storage that stores data regarding the switching elements and a secondary storage for facilitating replication of at least a portion of data across the NIB storages of the different controllers. In some embodiments, the primary purpose for one or more of the secondary storage structures is to back up the data in the NIB. In these or other embodiments, one or more of the secondary storage structures serve a purpose other than backing up the data in the NIB. In some embodiments, the NIB is stored in system memory while the system operates for fast access of the NIB records. In some embodiments, one or more of the secondary storage structures are stored on disks which can be slower to access.

摘要： Some embodiments provide a method of processing a packet through a logical switching element implemented by several managed switching elements. The method receives a packet for processing through a logical processing pipeline of the logical switching element. The method processes the packet through the logical processing pipeline. The method stores state information in the packet for indicating that the packet has been processed through the logical processing pipeline in order to prevent other managed switching elements from processing the packet through the logical processing pipeline. The method forwards the processed packet to a managed switching element of the several managed switching elements.

摘要： A pipelined linecard architecture for receiving, modifying, switching, buffering, queuing and dequeuing packets for transmission in a communications network is disclosed. The linecard has two paths: a receive path and a transmit path. In the receive path, received packets are processed and switched in an asynchronous, multi-stage pipeline. The pipelined switch operates on several packets in parallel while determining each packet's routing destination. Once that determination is made, each packet is modified to contain new routing information. Each packet is buffered and enqueued for transmission over the switching fabric to a destination linecard. The transmit path includes a buffer/queuing circuit similar to that used in the receive path. Both enqueuing and dequeuing of packets is accomplished using a CoS-based decision making apparatus.
