An apparatus comprising an input circuit to receive packets of data from a network. A wireless output circuit transmits respective ones of the packets of data wirelessly to one or more wireless clients. A wireless input circuit receives wireless signals from the one or more wireless clients. An output circuit transmits one or more predetermined packets repeatedly to the network on behalf of one of the wireless clients in response to a respective one of the wireless signals received by the wireless input circuit from the one of the wireless clients.

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.

An apparatus having a corresponding method and computer program comprises a control circuit to determine a number N of network devices belonging to a virtual local area network, wherein the virtual local area network does not require authentication of the network devices; and a policy circuit to limit an aggregate data rate of the virtual local area network according to the number N of network devices belonging to the virtual local area network.
摘要:
A network switch including a port, a memory, and a controller. The port has a port identifier and receives a packet (including an address of the source device) transmitted from a source device to the network switch. The memory is configured to store entries, each entry including (i) an identifier of a port of the network switch and (ii) an address of a network device. The controller is configured to (i) determine whether the address of the source device and the port identifier of the packet are stored in the memory and (ii) send a message to a processor requesting approval of the packet. The controller is configured to send the message when (i) the address of the source device is not stored in the memory or (ii) the port identifier of the packet is not stored with the address of the source device as one of the entries.
摘要:
A packet processor for a network device includes an incoming port that receives a first packet. The first packet includes a data portion, a control portion and a first outgoing port. A control data processing device receives the control portion from the incoming port while the data portion is stored in memory, and transmits the control portion to the first outgoing port. The first outgoing port transmits a first request for the data portion based on the control portion. A header altering device retrieves the data portion from the memory and strips, modifies, and encapsulates the data portion based on the first request.
