| 20090016331 | Path diversity index for use in route selection - In one embodiment, a method includes receiving at a network device information on paths to a destination node, determining a number of common nodes or links between at least two of the paths, calculating a path diversity index based on the number of common nodes or links, and selecting a route to the destination node based on the path diversity index. An apparatus for calculating path diversity index for use in route selection is also disclosed. | 01-15-2009 |
| 20090097409 | Dynamic Selection Between Active and Passive Probing in Computer Network - In one embodiment, during network operation, it is dynamically determined whether to change from passive probing of communication path metrics to active probing of communication path metrics. | 04-16-2009 |
| 20090198832 | EVENT TRIGGERED TRACEROUTE FOR OPTIMIZED ROUTING IN A COMPUTER NETWORK - In one embodiment, a network device (e.g., a master controller) may detect an event on a current path in a computer network from a local network domain to a destination address prefix of a remote domain. In response, the device may dynamically (e.g., intelligently) determine a trace target destination address within the destination address prefix, and may perform (or request performance of) a Traceroute of the current path and a selection of alternate paths in the network from the local network domain to the trace target, where the Traceroute is adapted to obtain per-hop measurements along the respective traced path. The measurements may then be stored, for example, to be used for optimal path selection, fault identification reporting, etc. | 08-06-2009 |
| 20100110891 | SHARING PERFORMANCE MEASUREMENTS AMONG ADDRESS PREFIXES OF A SAME DOMAIN IN A COMPUTER NETWORK - In one embodiment, performance measurements may be obtained at a local domain from a set of one or more responding targets of a particular remote domain. The performance measurements may then be applied to prefix-specific policies of any corresponding destination address prefix within the particular remote domain, such that traffic destined to a particular prefix of the particular remote domain may be routed from the local domain based on the corresponding prefix-specific policies and applied performance measurements. | 05-06-2010 |
| 20100128606 | FIRST-HOP DOMAIN RELIABILITY MEASUREMENT AND LOAD BALANCING IN A COMPUTER NETWORK - In one embodiment, probe messages may be transmitted from a local domain to a set of one or more responding probe targets located beyond a plurality of probed first-hop domains of the local domain, the probe messages transmitted via each of a plurality of probed first-hop domains. A reliability of each probed first-hop domain may then be determined based on responsiveness of probe messages transmitted via each respective probed first-hop domain, such that traffic destined beyond the probed first-hop domains may be load balanced across the probed first-hop domains based on the respective reliability, regardless of a traffic-class and a destination of the traffic. | 05-27-2010 |
| 20100265825 | TECHNIQUE FOR POLICY CONFLICT RESOLUTION USING PRIORITY WITH VARIANCE - In one embodiment, a value for a option for a particular policy of a plurality of policies that are ranked in a priority order is ascertained. A variance to the value associated with the option for the particular policy is applied to define a range of acceptable values for the particular policy. A determination is made whether one or more other options exist that have values within the range of acceptable values for the particular policy. If no other options exist that have values within the range of acceptable values for the particular policy, the option is selected If other options exist that have values within the range of acceptable values for the particular policy, the ascertaining, applying and determining is repeated for a next lower priority policy of the plurality of policies to consider the other options, the repeating to occur successively until an option is selected. | 10-21-2010 |
| 20100309795 | DYNAMICALLY RIGHT-SIZING PREFIXES FOR NETWORK AND APPLICATION PERFORMANCE - In one embodiment, performance parameters may be determined for each of a plurality of network address prefixes in a computer network. Based on the respective performance parameters, the prefixes may be resized through at least one of consolidation of adjacent prefixes and splitting of prefixes, and traffic may then be routed in the computer network based on the resized prefixes. | 12-09-2010 |
