  • Methods, systems, and computer program products for dynamic network access device port and user device configuration for implementing device-based and user-based policies
    Patent number: 8775571
    Abstract: Methods, systems, and computer program products for dynamic network access device port and user device configuration are disclosed. According to one method, when a user device is connected to a port of a network access device, the type of user device is determined. The type of user device is used to locate a corresponding port configuration policy. The port to which the device is connected is dynamically configured based on the port configuration policy.

  • Methods and systems for associating and translating virtual local area network (VLAN) tags
    Patent number: 7558273
    Abstract: Methods and systems for associating and translating VLAN tags are disclosed. In one implementation, multiple different member VLAN tags are associated with a translation VLAN tag. When a frame addressed to an unknown MAC address and containing one of the member VLAN tags is received, the frame is flooded to the translation VLAN and to ports associated with the source member VLAN other than the originating port. In the copy sent to the translation VLAN, the VLAN tag is replaced with the tag of the translation VLAN, for tagged ports. For untagged ports, the input VLAN tag may simply be stripped from the frames. When a layer 2 frame addressed to an unknown MAC address and containing the translation VLAN tag is received, the layer 2 frame is flooded to each of the member VLANs and to ports of the translation VLAN other than the originating port. The VLAN tag in the frames forwarded to each of the member VLANs may be replaced with the VLAN tag corresponding to each member VLAN, for tagged ports.

  • Method and apparatus for server load balancing
    Patent number: 6980550
    Abstract: A method for forwarding data packets to one of a plurality of servers comprising receiving a data packet from a source, at a data packet forwarding device having a plurality of ports, performing a hashing function using a unique component of the data packet as a seed value for the hash, generating a hash value using the hashing function, looking up a table for an address of one of the plurality of servers using the hashed value as an index to the table, and forwarding the data packet to a server corresponding to the address.

  • Method and system for multicast traffic reduction
    Patent number: 6977891
    Abstract: A method is provided to reduce multicast traffic by snooping IGMP control packets on a packet-forwarding device. A multicast traffic reducer includes an IGMP proxy, which operates in conjunction with an IGMP snooper to intercept selected IGMP control packets and generate proxy IGMP control packets in their place. The IGMP proxy may include an IGMP query batcher to consolidate IGMP queries to multicast host groups, an IGMP query responder to consolidate host responses to the IGMP queries to multicast host groups, and/or an IGMP leave forwarder to manage host IGMP leave packets. The IGMP proxy consolidates or discards host-generated IGMP control packets and timely generates IGMP proxy control packets in their place. The IGMP proxy further includes an IGMP layer-2 query generator to initiate IGMP queries for a layer-2 router multicast application.
