| 20090296579 | EFFICIENT CONVERGENCE OF GROUPED VPN PREFIXES - In one embodiment, one or more virtual private network (VPN) prefixes may be grouped at a network node into sets having shared network border node next-hop options, where each border node has a defined index value associated therewith. Also, a list of VPN labels associated with each VPN prefix may be maintained by the network node, where each VPN label is associated with a border node of a particular set by a corresponding index value. Further, the network node may determine a particular border node for traffic to be forwarded, along with the defined index value. The network node may then apply the index value to select an associated VPN label, and may affix the selected VPN label to the traffic for forwarding. | 12-03-2009 |

| 20090193105 | Local placement of large flows to assist load-balancing - In one embodiment, an apparatus generally comprises one or more input interfaces for receiving a plurality of flows, a plurality of output interfaces, and a processor operable to identify large flows and select one of the output interfaces for each of the large flows to load-balance the large flows over the output interfaces. The apparatus further includes memory for storing a list of the large flows, a pinning mechanism for pinning the large flows to the selected interfaces, and a load-balance mechanism for selecting one of the output interfaces for each of the remaining flows. A method for local placement of large flows to assist in load-balancing is also disclosed. | 07-30-2009 |

| 20090010158 | QUASI RTP METRICS FOR NON-RTP MEDIA FLOWS - In one embodiment, a router receives a real-time multimedia flow that comprises IP packets. The router then processes values included in the Identifier fields of the IP packets using resources similar to those used in the monitoring of RTP flows to identify metrics for the real-time multimedia flow. The metrics may be transferred to a remote management device for aggregation with metrics output by other routers located on the data path for the real-time multimedia flow. | 01-08-2009 |

| 20090122805 | Instrumenting packet flows - Disclosed are, inter alia, methods, apparatus, computer-readable media, mechanisms, and means for instrumenting real-time customer packet traffic. These measured delays can be used to determine whether or not the performance of a packet switching device and/or network meets desired levels, especially for complying with a Service Level Agreement. | 05-14-2009 |
| 20090201808 | Rate Controlling of Packets Destined for the Route Processor - Packets destined for the route processor of a packet switching device are rate controlled. Typically, line cards are configured to rate limit packets of offending packet flows destined for the route processor, such, but not limited to in response to a quantity of packets in the route processor. Filtering of packets of offending packet flows at the line cards reduces the work required of the route processor. | 08-13-2009 |
| 20100215047 | SUBSETS OF THE FORWARD INFORMATION BASE (FIB) DISTRIBUTED AMONG LINE CARDS IN A SWITCHING DEVICE - Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with subsets of the Forward Information Base (FIB) distributed among line cards in a switching device; especially wherein one or more of the line cards does not contain the complete FIB, and this line card forwards packets, for which it does not have the forwarding information, to another line card which has the forwarding information for the packet. | 08-26-2010 |
