Abstract
A method and system for assigning priority or classes of service of messages delivered in a packet-based network. The method and system allows for implementation of differentiated classes of service according to the requirements of the network application or user.
Claims19
A network access server implementing differentiated classes of service, the network access server comprising:
- a plurality of communication devices receiving connections accessing a network;
- a shared communication bus in communication with the communication devices;
- an egress card in communication with the shared communication bus receiving the connections accessing the network, wherein the connections accessing the network are in a packet format;
- and
- a process for determining a class of service to mark Internet Protocol packets, wherein the process includes stamping a per hop behavior field within a type-of-service byte of at least one of the Internet Protocol packets, the per hop behavior field indicating the class of service for the Internet Protocol packets.

A network access server implementing differentiated classes of service, the network access server comprising:
- a plurality of communication devices receiving connections accessing a network;
- a shared communication bus in communication access with the communication devices;
- an egress card in communication with the shared communication bus;
- and
- a process for determining a class of service to mark Internet Protocol packets,
- wherein each of the Internet Protocol packets contains a per hop behavior field within a type-of-service byte of the Internet Protocol packets, the per hop behavior field defining the class of service for the Internet Protocol packets.
3 more elements
A method comprising:
- establishing a connection to a packet-based network;
- determining a per hop behavior field for an Internet Protocol packet, the per hop behavior field defining a class of service for the Internet Protocol packet;
- stamping the per hop behavior field at a type-of-service byte of the Internet Protocol packet;
- and
- sending the Internet Protocol packet to the packet-based network,
- whereby the packet-based network transports the Internet Protocol packet in accordance with the class of service defined by the per hop behavior field.
