摘要： In one implementation, the power consumption by network devices may be managed by accessing a routing protocol that manages an allocation of processing resources in a network. The routing protocol may be used for generating a first configuration, for which a utilization of resources may be determined. A first cost for the first configuration may be determined. A second configuration may be identified to support the utilization of the resources. A second cost may be determined for the second configuration. The first cost may be compared to the second cost. The prospective performance of the network for the second configuration may be assessed. Based on the results of the comparison and the assessment, the network may be configured to use the second configuration. Processing resources may be activated on inactive network devices to support the second configuration and deactivated on active network devices that are not utilized in the second configuration.

摘要： Disclosed is a technique for data network congestion diagnosis using remote estimation of round-trip delays. A monitoring node transmits test messages between network nodes and measures the transit times between when the test messages are transmitted from, and when they return to, the monitoring node. A path delay between network nodes is determined based on the measured time delays. The techniques for determining network path delay are also utilized in conjunction with a three phase test procedure for diagnosing network congestion problems. Due to various network topologies and routing tables, certain confirmatory checks may be required to determine whether the procedures of the first or second phase test procedures are appropriate for particular path segments. Further, queuing delays may be determined by subtracting traffic independent delays from the measured transit times of the test messages, and such queuing delays may be used to determine the path delays. Such traffic independent delays may be determined during periods of low network traffic.
