Described are embodiments of methods, apparatuses, and systems for multi-protocol tunneling across a multi-protocol I/O interconnect of computer apparatus. A multi-protocol I/O interconnect may include a switching fabric operatively coupled to a first protocol-specific controller and a second protocol-specific controller, and may be configured to simultaneously route packets of the first protocol to the first protocol-specific controller and packets of the second protocol to the second protocol-specific controller. Other embodiments may be described and claimed.

A system and method of transferring cells through a switch fabric having a shared memory crossbar switch, a plurality of cell receive blocks and a plurality of cell transmit blocks. The system determines, based on a number of cells queued up in respective output buffers in the cell transmit blocks, output buffers in the cell transmit blocks that can receive cells on a low latency path. The cells transferred include first cells that can be transferred on the low latency path and second cells that cannot be transferred via the low latency path. The first cells are transferred via a bypass mechanism in shared memory to the output buffers. The second cells are transferred by writing the second cells to shared memory, reading the second cells from shared memory and transferring the second cells read from shared memory to the output buffers in the cell transmit blocks.

A data replication and switching device and method, including a plurality of data communication ports, a management port, at least one replicator respectively associated with the data communication port, a Layer 1 (L1) switch, and a L1 bypass. At least some data received via the at least one of the plurality of ports can be routed to at least one of the plurality of data communication ports and, in response to the configuration data received via the at least one management port, the data replication and switching device can route at least some of the data received via the data communication port to bypass the L1 switch or to route at least some of the data received via the data communication port to the L1 switch.

A routing node includes: at least one optical buffer, a switching node, and at least one transmission waveguide, where an output end of each optical buffer is connected to an input end of the switching node; each transmission waveguide is connected to an output end of the switching node. The optical buffer is configured to parse a received optical signal to obtain an identifier of a destination routing node, and send the identifier to the switching node. The switching node determines whether an output port required by the destination routing node is in an idle state or a busy state; and control the optical buffer to store the optical signal if the output port is in a busy state; or send the optical signal to the destination routing node if the output port is in an idle state.

A data replication and switching device and method, including a plurality of data communication ports, a management port, at least one replicator respectively associated with the data communication port, a Layer 1 (L1) switch, and a L1 bypass. At least some data received via the at least one of the plurality of ports can be routed to at least one of the plurality of data communication ports and, in response to the configuration data received via the at least one management port, the data replication and switching device can route at least some of the data received via the data communication port to bypass the L1 switch or to route at least some of the data received via the data communication port to the L1 switch.

The present disclosure relates to an example of a method for a first router to adaptively determine status within a network. The network may include the first router, a second router and a third router. The method for the first router may comprise determining status information regarding the second router located in the network, and transmitting the status information to the third router located in the network. The second router and the third router may be indirectly coupled to one another.

The invention describes the design of an interconnect element in a programmable network processor/system on-chip having multiple packet processing engines. The on-chip interconnection network for a large number of processing engines on a system can be built from an array of the proposed interconnect elements. Each interconnect element also includes local network lookup tables which allows its attached processing engines to perform lookups locally. These local lookups are much faster than the lookups to a remote search engine, which is shared by all processing engines in the entire system. Local lookup tables in each interconnect element are built from a pool of memory tiles. Each lookup table can be shared by multiple processing engines attached to the interconnect element; and each of these processing engines can perform lookups on different lookup tables in run-time.
