In this implementation some sort of store-and-forward routing for optical
bursts is deployed, where each burst is delayed for a certain time until its corresponding
control information is processed and an appropriate switching decision is determined,
that is, the burst could be forwarded to an output port, converted to another wavelength,
or simply dropped.

??? OBS.networks.for.Ethernet:.Extending Ethernet services over OBS was proposed
in Sheeshia, Qiao, and Liu (2002) as a more scalable and bandwidth-efficient implementation
compared to the Ethernet over Synchronous Optical Network (SONET).
The possible role that OBS will play in the development of 10-Gbit Ethernet (10GbE)
metropolitan networks was investigated. OBS was demonstrated as an improved network
resource-sharing platform and efficient transport for Ethernet traffic, particularly
if it is coupled with the Generalized Multiprotocol Label Switching (GMPLS).
It is clear that OBS is a technology-driven paradigm; consequently, the architecture and the
operational policies of the future OBS networks will be shaped by the upcoming developments
in the multiplexing and switching technologies.
