Abstract:
1. A sending device for use in a packet switching network system for transferring packetized information, comprising: a sending digital buffer with a predetermined sending buffer size, the sending digital buffer configured to store information provided by a user that is to be sent to a destination device through the packet switching network, wherein the sending device is configured to send a request packet including the sending buffer size to the destination device through the packet switching network, wherein said sending device includes: wherein the sending device and the destination device enter into negotiations as to a mutually-acceptable digital buffer size that is to be used for information transfer through the packet switching network system thereby increasing system performance by reducing or avoiding delays experienced by the user and the negotiations terminate upon one of the receiving a confirmation packet acknowledging the sending buffer size can be supported, the request packet is sent a number of times until a predetermined number of requests is reached with no response, receiving a reject message indicating that the sending buffer size is not supported at the destination device resulting in the sending device and destination device will use their own buffer sizes, a predetermined time interval equal to the predetermined number of requests multiple by a time associated with sending the request packet and receiving the confirmation packet expires, or a request for a different buffer size than was sent in the request packet is received generated at the destination device.
