System and method for processing network packet flows
View Patent ↗A system and method provides a broadband network node for a best effort network such as the Internet or intranets which supports the inexpensive and rapid deployment of services to the best efforts network. Separate data path and control path mechanisms allow high-speed data transfers with parallel processing flows for the data path that are controlled across data flows by the control path. Packets are classified, modified and shaped to enable the service on the network with an accountant to track packet traffic for control and billing purposes. A series of processing blades perform a modification function for each blade that processes packets according to classifications. The processing blades are modular and scalable for insertion in the broad band switch to rapidly adapt the broadband network node for new services.
1. A method for providing a service on a packet-based network, the method comprising:
monitoring network traffic with a processor to detect control protocol information;
extracting control protocol information from the network traffic;
using reflective programming to create a new dataflow program for monitoring packets associated with at least some of the extracted control protocol information; and
monitoring the network traffic with the new dataflow program; wherein the new dataflow program comprises rules based on IP addresses extracted from MAC IP mapping.
2. A method for providing a service on a packet-based network, the method comprising:
monitoring network traffic with a processor to detect control protocol information;
extracting control protocol information from the network traffic;
using reflective programming to create a new dataflow program for monitoring packets associated with at least some of the extracted control protocol information; and
monitoring the network traffic with the new dataflow program; wherein the control protocol information comprises a lookup request to a first server for the IP address and port number of a second server having predetermined information.
3. The method of claim 2 wherein the new dataflow program comprises instructions to create another dataflow program.
