Fairness in ATM networks

In the future broadband ISDN which will be based on statistical multiplexing, generally speaking, three traffic categories may be defined: (1) guaranteed bandwidth traffic, (2) non-guaranteed variable bit rate video traffic, and (3) other non-guaranteed variable bit rate traffic (mainly data) which will be competing for the spare capacity. The special focus of this paper is on a fairness definition for the third traffic category as applied mainly to customer premises or local ATM networks. The paper provides a quantitative standard for the apportionment of the spare capacity among traffic streams of the third category, taking into consideration special capacity requirements of different sources. © 1993.
