  • Patent number: 9325622
    Abstract: Mechanisms are provided for performing traffic load balancing on ingress traffic directed to a Link Aggregation Group (LAG). The mechanisms monitor a ingress traffic load across a plurality of links of the Link Aggregation Group (LAG). The mechanisms determine if the ingress traffic load across the plurality of links is unbalanced. Moreover, the mechanisms, in response to determining that the ingress traffic load across the plurality of links is unbalanced, send a message to a switch associated with the LAG requesting the switch to modify routing of ingress traffic to the LAG to perform ingress traffic load balancing.

  • Patent number: 9236906
    Abstract: A transmitter device transmits data over a physical communication link to at least one destination. A monitor resource monitors a frequency band of signals on the physical communication link. At least a portion of the monitored frequency band in the physical communication link used to transmit the data is also allocated for transmissions of wireless communications in a vicinity of the physical communication link. The physical communication link may be damaged for any number of reasons such as a loose connector, rodent chewing on the physical communication link, etc. The damaged locations of the physical communication link are places where the wireless communications are more likely to couple onto the physical communication link and cause interference. In response to detecting presence of an interference signal in the monitored frequency band of the physical communication link, the monitor resource transmits one or more notifications.
