摘要： A packet node and corresponding methods are provided for providing services to packets received at the packet node. At an ingress card, a packet is classified and a virtual media access control (VMAC) address is attached to the packet. The VMAC address identifies a service component for providing a service to the packet. Layer two switching of the packet is made within the packet node, based on the VMAC address. After processing of the packet by the service component, a new VMAC address is attached to the packet. Further layer two switching of the packet, based on the new VMAC address, may lead to further processing by another service component or to forwarding of the packet beyond the packet node.

摘要： A method applied in a routing node, and a forwarding engine implemented in a routing node, are provided for handling data packets received at the routing node. A N-tuple comprising N elements is extracted from a first header of a data packet. A default meta-field is added to the N elements, providing a N+1-tuple. The N+1- tuple is used to make a first lookup of inspection rules. The default meta-field makes the inspection rules apply to the first header. The data packet is handled according to a result of the first lookup, wherein a possible outcome is a finding of a second header within the data packet. If a second header is found, a new meta- field value is set and a second lookup is made. The second lookup of the inspection rules is made according to N elements from the second header and the new value of the meta-field.

摘要： Method and router supporting tracing of a packet therein. A first service module receives the packet and a memory module stores a tracing extension header. The extension header comprises an identifier of a receiving service module and a tracing identifier associated with the packet. The extension is stored following reception of the packet by the first service module. Optionally, the receiving module may be the first service module that further receives the packet through a network interface module. The first service module may also generate the tracing identifier associated with the packet that uniquely identifies the tracing in the receiving module. The router may comprise a second service module and a second memory module associated thereto. The first service module may further append the tracing extension header to the packet and forwards the packet to the second service module. The second memory module may then store the extension header thereupon.

摘要： A load balancer (110) in a communication network (100) tracks active network flows using a Bloom filter and takes a snapshot of the Bloom filter at the time of a scaling event. The load balancer (110) uses the Bloom filter snapshot to differentiate packets belonging to pre-existing network flows from packets belonging to new network flows. Packets belonging to pre-existing network flows continue to be distributed according to a mapping function in use prior to the scaling event. Packets belonging to new network flows are distributed according to a new mapping function.

摘要： A Packet Core Function (PCF) (55) and a method of automatic Packet Data Service Node (PDSN) Discovery, Monitoring, and Failure Handover in a packet-switched network that includes a plurality of PDSNs (57). The PDSNs multicast PDSN profile information that includes their ID, status, congestion level, and routing table information. The PCF automatically builds and updates a PDSN database (61) from the profile information it receives. If the PCF fails to receive a predefined number of multicast messages, or fails to receive responses to polling messages from a particular PDSN, the PCF concludes that the PDSN has failed. If a failure is detected, the PCF selects one or more new PDSNs to handle the packet data sessions that were being handled by the failed PDSN. The PCF then hands over the active sessions to the selected PDSN(s).
