  • Patent number: 8670423
    Abstract: The present invention provides a system (600), device (500) and method (400) for automatic partner selection in an existing Cooperative MAC (CMAC) protocol, which uses the Ready-to-Send (RTS), Clear-to-Send (CTS) and Partner-Clear-to-Send (PCTS) handshaking to establish cooperation. The present invention enables a “best” partner/relay (500.R.k) who is also willing to cooperate to relay information to a destination (500.D.J) for the transmitting device (i.e., the source), without the source (500.S.i) making a decision on partner selection. That is, the present invention provides a new mechanism by which the best partner/relay (500.R.k) that is also willing to cooperate will “step in” automatically without the source's involvement in selection of the partner/relay (500.R.k). This mechanism is contention-based and the partner is “selected” using local information only in a fully distributed manner.

  • Patent number: 8670444
    Abstract: In a virtual network apparatus, even when a fault occurs on a private line connecting plural physical network apparatuses to communicate a control signal, the redundancy is maintained, and the lower forwarding capability is prevented. In this network system, a control signal for virtualization to be transmitted and received between plural physical network apparatuses is relayed via a unit spanning LA connecting each physical network apparatus and an adjacent network apparatus in the adjacent network apparatus. Thereby, even when a fault occurs in the private line, it is possible to continue to communicate the control signal between the physical network apparatuses and continuously operate the virtual network apparatus.

  • Patent number: 8670446
    Abstract: An Ethernet Metropolitan Area Network (10) provides connectivity to one or more customer premises (161, 162, 163) to packet-bases services, such as ATM, Frame Relay, or IP while advantageously providing a mechanism for assuring security and regulation of customer traffic. Upon receipt of each customer-generated information frame (20), an ingress Multi-Service Platform (MSP) (122) “tags” the frame with a customer descriptor (22?) that specifically identifies the recipient customer. In practice, the MSP tags each frame by overwriting the Virtual Local Area Network (VLAN) identifier (22) with the routing descriptor. Using the customer descriptor in each frame, a recipient Provider Edge Router (PER) (18) or ATM switch can map the information as appropriate to direct the information to the specific customer. In addition, the customer descriptor (22?) may also include Quality of Service (QoS) allowing the recipient Provider Edge Router (PER) (18) or ATM switch to vary the QoS level accordingly.

  • Patent number: 8670448
    Abstract: Traffic control services include detecting an occurrence of an activity via a computer processor. The activity subject to the detecting includes a presence of a device. The services also include obtaining traffic management support information associated with a source and destination of the activity. The traffic management support information includes user-defined preferences for controlling traffic to the device. The services further include determining whether the source and the destination supports traffic management activities, and if the source and the destination support the traffic management activities the computer processor subscribes to traffic messages provided by the source and implements traffic management activities for the source and the destination based upon the traffic messages and the user-defined preferences. If the source and the destination do not support the traffic management activities, the computer processor performs default traffic management activities.
