Performance Analysis of the Signaling Channels of OBS Switches
Nowadays, fiber optic networks that make transmission possible
in high capacities become widespread. There is a partial decrease
in network problems with the capabilities provided by these
networks such as telephone, wide area network, Internet, video
conference on a single fiber line. Also in optical networks,
optical burst switching that is a new technology stands out by its
some partial benefits. Optical burst switching (OBS) is a
promising solution for all optical networks. In this paper, a
program is developed which simulates signaling channel of an
OBS switch, for signaling messages that uses signaling protocols
while going from source node to destination node through
intermediate OBS switches. In this study, some models for interarrival
time of the signaling messages and processing time in the
service are used and a comparison of these models with the other
well known models is done (M/M/1/K queuing model and a
model using self-similar traffic as arrival process).
