摘要： Method and system for a network switch element is provided. The switch element includes a plurality of megaports, each megaport uniquely identified by a unique megaport address identifier for network addressing. Each megaport includes a plurality of operational ports, each operational port identified by a unique operational port address identifier. The switch element also includes a local crossbar for communication between the plurality of operational ports, and a shared logic module configured to provide common control of the plurality of operational ports within a megaport to allow operational ports to share resource of a single megaport to route network packets there between. The switch element also includes a global crossbar configured to allow communication between the megaports.

摘要： A system and method for transmitting and bundling network packets is provided. The incoming network packet size is determined and if the remote buffer space is sufficient to hold the network packet it is transmitted to the destination port. If the remote buffer space is not enough to hold the network packet it is discarded. The system includes an arbitration module that receives remote buffer space information and transmits the network packet if the remote buffer space has enough space to hold the packet. The arbitration module also determines if a second network packet is from a same source port having a same source virtual lane, and has the same destination virtual lane (bundling conditions). If the second network packet meets the bundling conditions, then it is transmitted after the first network packet, even if other packets were received before the second network packet.

摘要： A system and method for discarding expired network data packets is provided. A time stamp value is assigned to data packets that are received in a data packet queue, wherein the time stamp value is based on a counter value. The time stamp value is extracted after the counter value changes or a new data packet is received at the head of the data packet queue. The extracted time stamp value is then compared with the counter value. Data packets with expired timer value are discarded.

摘要： A storage area network (“SAN”) and a system is provided. The SAN includes, a host bus adapter operationally coupled with a credit extender, wherein the credit extender receives frames from a Fibre Channel network and sends the received frames to the HBA based on buffer space available in the HBA. The HBA notifies other Fibre Channel ports of buffer space available in the credit extender. The HBA sends a signal to the credit extender notifying the credit extender of available buffer space in the HBA. The HBA includes a management port for interfacing the HBA with the credit extender.
