SUMMARY:Modeling and blocking probability evaluation for multi-priority
 circuit switched optical networks
DESCRIPTION:It is expected that circuit switching (CS) will play an
 important major role in future optical networks. CS normally does not
 require buffering which is very costly in the optical domain. If the
 traffic on a CS network is well managed CS networks can guarantee quality
 of service (QoS) to customers in a way that can even lead to efficient link
 utilization and low consumption of energy per bit. In the core Internet\,
 where traffic is heavily multiplexed\, it is easier to achieve high
 utilization and therefore the role of CS at the core is clearly important.
 However\, CS can also lead to a green and efficient operation end-to-end
 for large bursts of data. Accurate\, robust and scalable blocking
 probability evaluation is an important element in CS traffic management. We
 consider an optical network that uses various circuit-switching based
 technologies such as OCS and OFS. We model it as two-priority
 circuit-switched network with non-hierarchical alternate routing. We
 evaluate the blocking probability using algorithms based on the Erlang
 Fixed-point Approximation (EFPA) and the Overflow Priority Classification
 Approximation (OPCA). For a particular example of a 6-node fully meshed
 network with alternate routing\, we compare numerically between OPCA over
 EFPA and discuss traffic implications.\n\nBiography: Moshe Zukerman
