Abstract: In general, techniques are described for organizing execution of distributed operating systems for network devices. A device comprising hardware computing nodes may be configured to perform the techniques. The hardware computing nodes may execute a protocol by which to discover a topology of the plurality of hardware computing nodes, and determine, based on the topology, a subset of the plurality of hardware computing nodes to manage execution of a distributed operating system. The determined subset of the plurality of hardware computing nodes may execute a communication bus by which to synchronize operating system state information between the subset of the plurality of hardware computing nodes. The hardware computing nodes may further execute, based on the operating system state information, the distributed operating system to provide an execution environment in which one or more applications execute.

Abstract: In general, techniques are described for communicating state information in distribute operating system. A network device comprises a first hardware node and a second hardware node. The first hardware node may execute a first instance of a distributed operating system, and maintain a first data structure that stores a plurality of objects defining a portion of state information. The second hardware node may execute a second instance of the distributed operating system, and maintain a second data structure that stores synchronized versions of the plurality of objects. The first hardware node may further receive updated state information, update the first data structure to include the updated state information, and synchronize the updated first data structure with the second data structure. The second hardware node may synchronize the second data structure with the updated first data structure.

Abstract: A method and apparatus for performing a lookup in a switching device of a packet switched network where the lookup includes a plurality of distinct operations each of which returns a result that includes a pointer to a next operation in a sequence of operations for the lookup. The method includes determining a first lookup operation to be executed, executing the first lookup operation including returning a result and determining if the result includes a pointer to another lookup operation in the sequence of operations. If the result includes a pointer to another lookup operation, the lookup operation indicated by the result is executed. Else, the lookup is terminated.

Abstract: The invention is directed to techniques for supporting multi-link protocols within a computer network. In one embodiment, a method includes receiving a set of data blocks from a plurality of links in one or more interface cards according to a multi-link protocol and sending the data blocks to a multi-link service card for sequencing. The data blocks may then be sent to the one or more interface cards for communication to a destination device over a computer network. Implementing a multi-link service card may allow a network device, such as a router, to support multi-link protocols.

Abstract: A method and apparatus for switching a data packet between a source and destination in a network. The data packet includes a header portion and a data portion. The header portion includes routing information for the data packet. The method includes defining a data path in the router comprising a path through the router along which the data portion of the data packet travels and defining a control path comprising a path through the router along which routing information from the header portion travels. The method includes separating the data path and control path in the router such that the routing information can be separated from the data portion allowing for the separate processing of each in the router. The data portion can be stored in a global memory while routing decisions are made on the routing information in the control path.
