This paper investigates the throughput performance of the d-tree multicast capable optical cross-connect (MC-OXC) by using the separated unicast/multicast splitter-and-delivery (SUM-SaD) switches under synchronous traffic. A d-tree property is introduced to constrain the ability that the MC-OXC and SUM-SaD can accommodate the numbers of light trees. We propose the maximal independent set (MIS) model...
We propose a novel separated unicast/multicast splitter-and-delivery (SUM-SaD) switch for mixed unicast and multicast traffic. Only multicast connections undergo extra splitting loss but are compensated by incorporated optical amplifiers. A typical multicasting-capable optical cross-connect is constructed by using the proposed SUM-SaDs. Theoretically, we prove that it is strictly nonblocking for both...
Automatically switched optical network (ASON) is controlled with the help of generalized multi protocol label switch (GMPLS) protocol. It enables telecom operators automatic traffic provisioning for enhanced network protection, operation and maintenance, but the deployed ASON/GMPLS realizes only point-to-point connections. The emerging broadband services, such as IPTV and e-Science, would need point-to-multipoint...
