The signaling scheme in an OBS network is typically implemented using out-of-band burst header packets. Classification of Signaling Schemes one-way, two-way, or hybrid reservation source-initiated, destination-initiated, or intermediate-node-initiated reservation persistent or non-persistent reservation immediate or delayed reservation explicit or implicit release of resources centralized or distributed signaling One-way, Two-way, or Hybrid In one-way reservation the source node sends out a control packet requesting each node in the route to allocate the necessary resources and to configure their cross-connects the data burst is then sent out without waiting for an acknowledgement it is possible that the reservations were not successful and the burst is dropped. But, the data burst can be sent out sooner, thereby reducing the end-to-end data transfer latency One-way, Two-way, or Hybrid In two-way reservation Signaling techniques are acknowledgment based The data burst is transmitted only after the acknowledgement is received .
