Renegotiated bit-rate service system and method
First Claim
1. A data transmission system comprising:
- a first site;
a second site;
a variable bit-rate network providing a connection between said first and said second sites;
a first memory storing a series of data segments;
a second memory storing a previously compiled record of instantaneous transmission rates, each of said stored rates being associated with one or more of said stored data segments; and
a network controller adapted to negotiate a connection between said first site and said second site having a particular bandwidth in response to the contents of said second memory.

Abstract
A data transmission system and method employing either a renegotiated variable bit-rate ("RVBR") network or a renegotiated constant bit-rate ("RCBR") network. Within these networks, data transmission rates between a sender and a recipient are rapidly renegotiated as a function of previously stored data transmission rate information and system buffer levels. Such a system and method can be readily implemented within existing CBR and/or VBR network architectures. The RCBR and RVBR networks allow for the implementation of an intelligent data traffic management systems that are responsive to the rate at which new calls or requests for connections enter and leave the network, the frequency and duration of extended peak rate data bursts, as well as the occurrence of short duration data transmission peaks.

13. A method for effecting a transmission between a first site and a second site via a variable bit-rate network, comprising the steps of:
-
providing a connection between said first and said second sites via said variable bit-rate network; storing a series of data segments within a first memory; retrieving from a second memory a value of an instantaneous data transmission rate, said stored rate being associated with one or more of data segments that are transmitted; negotiating a particular bandwidth connection via said variable bit-rate network in response to a said retrieved instantaneous data rate value; and transmitting said one or more data segments associated with said retrieved instantaneous data rate value between said first site and said second site via said variable bit-rate network. - View Dependent Claims (14, 15, 16)

17. A method for effecting a transmission between a first site and a second site via a constant bit-rate network, comprising the steps of:
-
providing a connection between said first and said second sites via said constant bit-rate network; storing a series of data segments within a first memory; retrieving from a second memory a value of an instantaneous data transmission rate, said stored rate being associated with one or more of data segments that are transmitted; negotiating a particular bandwidth connection via said constant bit-rate network in response to a said retrieved instantaneous data rate value; and transmitting said one or more data segments associated with said retrieved instantaneous data rate value between said first site and said second site via said constant bit-rate network. - View Dependent Claims (18, 19, 20)
