A software-defined network (SDN) system, device and method comprise one or more input ports, a programmable parser, a plurality of programmable lookup and decision engines (LDEs), programmable lookup memories, programmable counters, a programmable rewrite block and one or more output ports. The programmability of the parser, LDEs, lookup memories, counters and rewrite block enable a user to customize each microchip within the system to particular packet environments, data analysis needs, packet processing functions, and other functions as desired. Further, the same microchip is able to be reprogrammed for other purposes and/or optimizations dynamically.

A data processing system includes a phantom queue for each of a plurality of output ports each associated with an output link for outputting data. The phantom queues receive/monitor traffic on the respective ports and/or the associated links such that the congestion or traffic volume on the output ports/links is able to be determined by a congestion mapper coupled with the phantom queues. Based on the determined congestion level on each of the ports/links, the congestion mapper selects one or more non or less congested ports/links as destination of one or more packets. A link selection logic element then processes the packets according to the selected path or multi-path thereby reducing congestion on the system.

Phantom queue link level load balancing system, method and device

An apparatus for forwarding packets includes a packet processing pipeline having a processing unit that processes packets compliant with a recognized communication protocol. A first port coupled to the packet processing pipeline is configured to receive a packet that does not comply with the recognized communication protocol and has a header that conforms to a second communication protocol. A data extraction unit extracts first destination information from the header of the packet and, based on the first destination information, generates second destination information that conforms to the recognized communication protocol. The processing unit determines, based on the second destination information, an egress interface to which the packet is to be forwarded.

System and method for adapting a packet processing pipeline

A forwarding database cache system is described herein. The forwarding database cache system includes a main forwarding database and one or more forwarding database caches. When a packet is received, the cache is searched first for information such as address information, and if found, then the packet is forwarded to the appropriate destination. If the address information is not found in the cache, then the main forwarding database is searched, and the packet is forwarded to the appropriate destination based on the information in the main forwarding database.

This disclosure describes techniques and apparatuses enabling low-to-high speed cut-through communication without creating an overrun condition. By so doing, the techniques and/or apparatuses enable communication interfaces to communicate at higher speed, such as by avoiding store-to-forward latency.

Low-to-high speed cut-through communication

Protocol independent programmable switch (PIPS) software defined data center networks

In a modular switching device that includes a plurality of packet processors interconnected by a plurality of connecting devices, one or more data packets are received at a first packet processor. The first packet processor generates a communication frame that includes at least a portion of a first data packet among the one or more data packets. The first packet processor divides the communication frame into a plurality of transmission units, includes a communication frame identifier in respective transmission units, and includes a respective position identifier in respective transmission units. The transmission units are transmitted to the plurality of connecting devices via a first plurality of uplinks, and the plurality of connecting devices transmits the transmission units to the second packet processor via a second plurality of uplinks. The communication frame is reassembled from the plurality of transmission units using the communication frame identifier and the position identifiers.
