Abstract: A method is described and in one embodiment includes, for each of a plurality of outgoing ports of a first network element: collecting data comprising a number of packets arriving the outgoing port and an amount of power consumed by the outgoing port for a first time interval; calculating a packet per watt (“P/W”) metric for the port for the first time interval, wherein the P/W metric comprises the number of packets coming into the port divided by the amount of power consumed by the port during the first time interval; repeating the collecting and calculating for a number of successive time intervals; calculating a mean P/W metric for a time period comprising the first time interval and the successive time intervals; and calculating a variance for the time period comprising the first time interval and the successive time intervals. The method further includes redirecting traffic received at the network element to the outgoing port having the lowest variance.

Abstract: A method is provided in one example embodiment and includes calculating a packet metric for a first one of a plurality of links connected to a network element, wherein the packet metric is equal to a packet count over a period of time T divided by a maximum throughput of the first one of the links; and determining based on the packet metric whether traffic on the one of the links should be switched to another one of the plurality of links to optimize power usage. If a determination is made that the traffic on the first one of the links should be switched to another one of the plurality of links, the method further includes selecting a second link from a subset of the plurality of links; assigning the traffic to the selected second link; and applying a cost saving measure at an interface of the network element to which the first link is connected.

Abstract: Methods and systems for tracking transactions in a network fabric, include: receiving a message generated by a node in the network fabric; assigning a uniform fabric identifier (“UFID”) to the node; assigning a uniform transaction identifier (“UTID”) to the message”; appending the UFID and the UTID to the message; and storing the message in a database.
