Architecture, method and system of WDM-based photonic burst switched networks

A method for use in a wavelength-division multiplexed (WDM) photonic burst switched (PBS) network, the method comprising:

• receiving a control burst from the PBS network;
• de-framing the control burst;
• receiving a data burst associated with the received control burst from the PBS network;
• de-framing the data burst;
• and
• demultiplexing data from the de-framed data burst.

A machine-readable medium to provide instructions, which when executed by a machine, cause the machine to perform operations for use in a wavelength-division multiplexed (WDM) photonic burst switched (PBS) network, the operations comprising:

• receiving a control burst from the PBS network;
• de-framing the control burst;
• receiving a data burst associated with the received control burst from the PBS network;
• de-framing the data burst;
• and
• demultiplexing data from the dc-framed data burst.

A system comprising:

• a first network;
• and
• a photonic burst switched (PBS) network coupled to the first network, the PBS network further comprising an edge node that includes;
• a first interface to transfer information from the first network;
• a flow classifier to classify information received the first interface;
• a flow manager to selectively output information received via the flow classifier;
• and
• an ingress PBS component to transmit control and data information over the PBS network via an optical switch using information from the flow manager.

An apparatus for use in a wavelength-division multiplexed (WDM) photonic burst switched (PBS) network, the apparatus comprising:

• an optical-electrical (O-E) interface to receive an optical control burst via the PBS network;
• a control burst de-framer to de-frame optical burst information received from the O-E interface;
• a control burst processing component to determine bandwidth reservation information from the de-framed optical burst information;
• a PBS switch controller to determine configuration settings for an optical switch using the bandwidth reservation information;
• a control burst re-builder to rebuild the control burst after being processed by the control burst processing component;
• a control burst framer to frame the rebuilt burst from the control burst re-builder;
• and
• an electrical-optical (E-O) interface to transmit the framed control burst over the PBS network.

A method for use in a wavelength-division multiplexed (WDM) photonic burst switched (PBS) network, the method comprising:

• converting an optical control burst from the PBS network into an electrical control burst;
• de-framing the electrical control burst;
• determining bandwidth reservation information from the de-framed control burst;
• determining configuration settings for an optical switch responsive to the bandwidth reservation information, the optical switch switching an optical data burst associated with the control burst, the optical data burst received from the PBS network;
• rebuilding the control burst after processing the bandwidth reservation information;
• framing the rebuilt control burst;
• and
• transmitting another optical control burst over the PBS network containing the information of the framed rebuilt control burst.
