    摘要: Method and apparatus for modifying standard VLAN tags to perform network packet switching. The method includes receiving a data packet at a port of a network switch and determining whether the data packet has a virtual local area network (VLAN) tagged frame. If the received data packet has a VLAN tagged frame, then the method further includes modifying and encoding fixed portions of the VLAN tag frame with switching information. The switching information includes information for central management of data packet flow through the network switch.

    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 power sourcing equipment (PSE), a powered device (PD), and an approach for managing PoE power delivered from a PSE to a PD are described. Based on communication between the PD and the PSE, the PSE reduces the power made available to the PD in response to the PD entering an operational mode with reduced power requirements. Further, based on communication between the PD and the PSE, the PSE increases the power made available to the PD in response to the PD entering an operational mode with increased power requirements.

    摘要: A flow classifier for a network device that processes packets including packet headers includes a hash generator that generates hash index values from search keys derived from the packet headers. A hash table receives the hash index values and outputs pointers. A flow table includes flow keys and corresponding actions. A variable length (VL) trie data structure uses the pointers to locate the flow keys for the search keys. The VL trie data structure selects different flow keys for the search keys that share a common hash index value. The pointers include node, NIL and leaf pointers. The flow classifier performs a default action for the NIL pointers. A pointer calculator accesses a VL trie table using the pointers.
