  • Method and system for fast link failover
    Patent number: 8208370
    Abstract: A method and system for fast link failover is disclosed. According to one embodiment, a method is provided in which a failure of a first link between a network element and an upstream portion of a communications network is detected, and a second link or group of links between the network element and a downstream portion of the communications network is responsively disabled to maintain a communications channel between the downstream and upstream portions of the communications network.

  • Determining a profile for an interface of a network device
    Patent number: 7796634
    Abstract: Selecting a profile for an interface of a network device includes accessing profile sequences, where each profile sequence corresponds to an interface. Each profile sequence includes profiles that provide parameters for communicating data. The following are repeated for a profile sequence for an interface until a link satisfies a sequence criterion or until a last profile of the profile sequence is reached to select a profile for the interface. A current profile is accessed, and a link for the interface is initiated according to the current profile. Whether the link for the interface satisfies the sequence criterion is determined. A next profile of the profile sequence is accessed if the link does not satisfy the sequence criterion, and the current profile is selected if the link satisfies the sequence criterion. Data is communicated according to the selected profile.

  • Selecting a profile for an interface of a network device according to a margin
    Patent number: 7295569
    Abstract: Selecting a profile for an interface of a network device includes accessing profile sequences, where each profile sequence corresponds to an interface. Each profile sequence includes profiles that provide parameters for communicating data. The following are repeated for a profile sequence for an interface until a link satisfies a sequence criterion or until a last profile of the profile sequence is reached to select a profile for the interface. A current profile is accessed, and a link for the interface is initiated according to the current profile. Whether the link for the interface satisfies the sequence criterion in accordance with the margin set is determined. A next profile of the profile sequence is accessed if the link does not satisfy the sequence criterion in accordance with the margin set, and the current profile is selected if the link satisfies the sequence criterion. Data is communicated according to the selected profile.
