A packet switching network system for use in transferring information that is in the form of packets and including an originating device and a destination device for communicating therebetween through a packet switching network, the originating device including a sending device having a first buffer with a predetermined first buffer size, the first buffer being used to store information that is to be sent to the destination unit, the sending device for sending a request packet including the first buffer size, through the packet switching network, to the destination device, the destination device including a receiving device having a second buffer with a predetermined second buffer size, the second buffer size being used for storing information that is received from the originating device, the receiving device for receiving a request packet including the first buffer size from the originating device, determining whether or not the received first buffer size is supported by the destination device, and accordingly sending back a response, through the packet switching network, to the originating device, wherein, during initialization, the originating device and the destination device enter into negotiations as to a mutually-acceptable buffer size that is to be used for information transfer by the packet switching network system.

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.
