摘要： Systems, methods, and computer program products for modifying standard VLAN tags to perform network packet switching are described. In some implementations, a data packet can be received, and the data format of the data packet can be determined. Then, switching information associated with data package management is generated based on the data format of the data packet. The data packet can be modified using the generated switching information. For example, the modified data packet can be extended by a predetermined length to accommodate additional switching information.

摘要： A system including N ports, a memory, and a controller. The memory stores M address databases. Each of the M address databases stores MAC addresses and has a database number. A first port of the N ports associated with one of the M address databases receives a frame including a destination MAC address. The controller (i) generates a hashed MAC address based on the destination MAC address and (ii) combines the hashed MAC address and a first database number of the one of the M address databases to generate a bucket address. The bucket address identifies P addresses. Each of the P addresses identifies a location in the memory that stores (i) a MAC address and (ii) a port identifier. N, M, and P are integers greater than one.

摘要： A method includes transmitting a first frame having a first class of service and determining whether the first frame was successfully transmitted. An attempt count is incremented for the first class of service. When the first frame is not successfully transmitted, a second frame is transmitted having a second class of service before retransmitting the first frame when the second class of service is higher than the first class of service. Pending frames for the first class of service are discarded when at least one of the attempt count exceeds a predetermined attempt threshold and the first class of service falls below a predetermined discard threshold.
