Effective control of traffic flow in ATM networks using fuzzy explicit rate marking (PERM)
Pitsillides, Andreas; Sekercioglu, Y. Ahmet; Ramamurthy, G. (1997)In this paper, we describe the fuzzy explicit rate marking (FERM) traffic flow control algorithm for a class of best effort service, known as available bit rate (ABR), proposed by the ATM Forum. FERM is an explicit rate ...

Fuzzy backward congestion notification (FBCN) congestion control in asynchronous transfer mode (ATM) networks
Pitsillides, Andreas; Sekercioglu, Y. Ahmet; Ramamurthy, Gopalakrishnan (IEEE, 1995)In this paper, we study the performance of a fuzzy control scheme as a first step to develop better control strategies for avoiding congestion and attaining high link utilisation in ATM based networks. Due to the complexity ...

Fuzzy control of ABR traffic flow in ATM LANs
Sekercioglu, Y. Ahmet; Pitsillides, Andreas (IEEE, 1995)High-speed LANs are beginning to migrate from shared media to switch based configurations (commonly based on ATM architectures). Because of the characteristics of ATM networks and nature of LAN traffic, there is a need for ...
