Abstract
Frame Relay connectivity is provided via point to multipoint networks. Frame Relay access can thus be readily provided via point to multipoint networks such as data over cable networks and wireless networks. The end user obtains Frame Relay quality-of-service features via the point to multipoint network. The network service provider gains an additional method of access to the Frame Relay wide area network (WAN). Frame Relay quality of service information is translated into parameters appropriate for use with point to multipoint protocols so that point to multipoint network bandwidth may be properly measured.
Claims38
A method of providing Frame Relay services via a point to multipoint network comprising at least one subscriber node and a central access node in communication therewith using a multipoint protocol, the method comprising:
- generating a Frame Relay packet at said subscriber node of said point to multipoint network;
- encapsulating said Frame Relay packet within a point to multipoint protocol packet at said subscriber node;
- and
- forwarding said point to multipoint protocol packet including said encapsulated Frame Relay packet from said subscriber node to said central access node of said point to multipoint network, said central access node in communication with a Frame Relay network.
A method of providing Frame Relay services via a point to multipoint network comprising at least one subscriber node and a central access node in communication therewith using a multipoint protocol, the method comprising:
- receiving a point to multipoint protocol packet at said central access node of said point to multipoint network, said point to multipoint protocol packet having a Frame Relay packet encapsulated therein;
- extracting the Frame Relay packet from said point to multipoint protocol packet at said central access node;
- and
- forwarding said Frame Relay packet from said central access node via a Frame Relay network.
