摘要:
The invention provides methods and systems for providing priority processing to critical data as the data is transmitted across a network. A plurality of Internet protocol (IP) packets, each of which contains data and priority information, are received at a first router. The data contained in the IP packets is then encapsulated into frame relay frames containing the priority information. The frame relay frames are transmitted from the first router to a frame relay network in a manner determined by the priority information included in the frame relay frames. The frame relay flames are then transmitted across a frame relay network to a second router in a manner determined by the priority information included in the frame relay frames.

摘要:
An arrangement where a policy manager automatically generates configuration file updates for the routers in the network, as necessary, sends those updates to the appropriate routers, and causes the routers to install the configuration file updates in real-time. The automatic generation of configuration file updates is carried out in response to information that is delivered to the policy manager from a traffic measurement and flow analysis system that replaces the prior art analyzer system. The information that is generated by the traffic measurement and flow analysis system is sensitive to thresholds that the policy manager installs in the traffic measurement and flow analysis system.

A method and apparatus for use in a network utilizing Internet Protocol (IP), Resource Reservation Protocol (RSVP), and Asynchronous Transfer Mode (ATM) protocol is provided. An intelligent policy mapping database (PMD) accessible at the network level by both the RSVP and ATM protocol stacks maps RSVP parameters to ATM parameters with input from factors outside of the RSVP or ATM protocol stacks, e.g., general customer data. With the basis of customer data or other information outside of the RSVP and ATM protocol stacks, a network reservation message to the PMD contains RSVP flow specifications which are mapped to correlated ATM Quality of Service (QoS) parameters.
