摘要：The present invention refers to a method for managing the transmission ofoptical packets in a multi-ring optical packet switched network (200) wherein the optical
packets are divided into a first class having a first priority and a second class having asecond priority lower than the first priority and wherein the scheduling of the packets isdistributed in each node (N1, N2...N9) to provide scalability, the method comprising thefollowing steps: - encapsulation of the electronic packets of the client traffic (4)
comprising a timeout mechanism (11), (102) - queuing the optical packets correspondingto the encapsulated client packets into optical packet queues (Q1, Q2...Q5),(103) -scheduling the transmission of optical packets of different queues (Ql, Q2...Q5) based onpredefined priorities combined with a token bucket algorithm (5) and a timeoutmechanism (11) wherein the token bucket algorithm (5) is used to schedule the clientoptical packets of the first class to ensure a predefined quality of service and wherein thetimeout mechanism (11) is used to limit the duration between the reception of an
electronic packet from the client traffic (4) to the creation of an associated optical packetready to be transmitted through the multi-ring optical packet switched network (200).(105)
