| 20090323751 | METHOD AND DEVICE FOR USING OPTICAL FEEDBACK TO OVERCOME BANDWIDTH LIMITATIONS CAUSED BY RELAXATION OSCILLATION IN VERTICAL CAVITY SURFACE EMITTING LASERS (VCSELS) - A semiconductor device is provided that includes an optical feedback structure that is monolithically integrated with a VCSEL device and which extends the speed of the VCSEL device beyond the speed to which it would otherwise be limited due to relaxation oscillation.

| 20100195489 | INTERFACE MONITORING FOR LINK AGGREGATION - The present invention provides network interface monitoring and management that may be employed with link aggregation technologies. Multiple network interfaces may be aggregated into a single bond and data may be transferred to and from a backbone network via this aggregated bond. A link aggregation monitor employs a heartbeat generator, sniffer and data store to keep track of health and availability of network interfaces. The heartbeat generator sends heartbeats to the network interfaces, which pass the heartbeats around in a token ring configuration. If a network interface fails or otherwise goes offline, detection of this condition causes the monitor and heartbeat generator to prepare new or modified heartbeats so that data may be efficiently and accurately routed around the token ring and health of all remaining alive interfaces can be monitored properly. If a network interface re-enters or is added to the aggregate bond, new/modified heartbeats are then employed. | 08-05-2010 |
| 20110026520 | SYSTEM AND METHOD FOR IDENTIFYING MULTIPLE PATHS BETWEEN NETWORK NODES - Aspects of the invention pertain to transmitting packet data across a computer network. The packets may be sent via one or more distinct routes from a source to a destination. Each route may employ multiple routers disposed along the network. Non-colliding routes are determined by transmitting pairs of probe packets along the routes. A first probe packet has a maximal length, and a second probe packet has a minimal length. Depending on the order of arrival of the probe packets, the system determines whether two transport layer ports at the destination device collide. If there is a collision, then the system searches for a set of non-colliding ports. Once the non-colliding ports are determined, application data may be sent as packets along the different routes to those ports. | 02-03-2011 |

A first rule, for example a rule having a lowest priority, may be selected from among the plurality of flow rules, and it may be determined whether the first rule conflicts with any lower priority rules stored in the hardware resource with a highest capability. If the first rule conflicts with a lower priority rule in the hardware resource with the highest capability, the first rule may be stored in the resource with the highest capability. If the first rule does not conflict with a lower priority rule in the hardware resource with the highest capability, the first rule may be processed to identify the hardware resource with a lowest capability that can support the first rule, and the first rule may be stored in the identified resource. | 08-25-2011 |
