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.

Methods and apparatus for managing packets in a packet switched network include, in at least one aspect, a device including: an input to receive a packet from one of a plurality of network devices, the plurality of network devices configured to communicate with one or more others of the network devices using a plurality of packets; and circuitry configured to control packet switching of the plurality of packets, at least one packet including: a switch tag including a tag portion embedded with switching information and an extended tag portion embedded with additional switching information, the switching information and the additional switching information configured to control a switching pattern associated with the at least one packet.
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.

An embodiment includes a method that includes identifying a first functional effect that would be produced in an apparatus by executing in the apparatus one or more source commands. The embodiment includes determining whether the first functional effect is producible in the apparatus based on the apparatus executing one or more target commands written in a command language different than the language that the source commands are written in. The embodiment includes, in response to determining that the first functional effect is producible in the apparatus based on the apparatus executing the one or more target commands, producing an output comprising the one or more target commands for execution by the apparatus.

An embodiment includes a method that includes receiving source commands to establish a configuration to control a computer networking function in a computer networking device, wherein the source commands are written in a source command language. The method selectively translates the source commands from the source command language to target commands written in a target command language, wherein the translation is based, at least in part, on a function-to-function translation model. The configuration is established in the computer networking device based on the target commands.

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.

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.

Apparatus having corresponding methods and computer programs comprise a first first-in first-out buffer (FIFO) to receive and store data from a media access controller (MAC); a physical-layer device (PHY) to transmit a signal representing the data; and a control circuit comprising a read circuit to transfer the data from the first FIFO to the PHY, and a transmit pause circuit to transmit a pause frame to the MAC when an amount of the data stored in the first FIFO exceeds a predetermined threshold.
