Optical packet switching network.

It differs from these paradigms because obs control information is sent separately in a reserved optical channel and in advance. Infinera was an early adopter in this transition to packet bringing layer 2 ethernet functionality directly into metro and regional optical networks. Obs is viewed as a compromise between the yet unfeasible full optical packet switching ops and the mostly static optical circuit switching ocs. This provides the flexibility to choose the degree of packet and or otn switching based on the current demand.

Optical switching and networking considers high. On one hand various vendors operators and analysts define packet optical as a standalone network element that combines reconfigurable wavelength division multiplexing wdm transport. Packet optical networking has boomed in recent years driven by the well documented traffic growth in many sectors of the telecom market and the migration to ethernet based services. In optical packet switching technique packet header is being processed either optically or electronically at each intermediate node.

For example ciena s 6500 converged packet optical platform offers interfaces with flexible per port user selectable packet or otn switched services over a single wavelength making it easy to adapt to changing network requirements. Optical switching and networking osn is an archival journal aiming to provide complete coverage of all topics of interest to those involved in the optical and high speed opto electronic networking areas. In ocs the network is configured to establish acircuit from an entry to an exit node by adjusting the optica lcross connect circuits in the core routers in a manner that the data signal in an optical form can travel in an all optical manner from the entry to the exit. Optical circuit switching ocs is an optical networking technology.

The optical electronic o e conversion and viceversa is done as required. The data payload waits in delay lines of the fiber before being forwarded to the next node. Optical burst switching obs is an optical networking technique that allows dynamic sub wavelength switching of data.
