Abstract
In ATM UBR networks supporting TCP traffic, optimal efficiency can only be
envisaged if switches adopt a discard mechanism that operates at the packet
level rather than the cell level. In this paper, we define a variant of the RED
discard strategy suitable
for ATM switches. An interesting feature of this ATM-RED is that it has a simil
ar per-VC
implementation complexity as the Early Packet Discard (EPD) algorithm.
To study the efficiency of the ATM-RED discard strategy, we compare its performa
nce with plain the UBR,
EPD and Fair Buffer Acceptance (FBA) discard strategies by means of simulation w
ith TCP/IP traffic.
We give comparative results with respect to different performance criteria such
as goodput and
fairness in various environments.
