Currently, the contention resolution is one of research focuses for optical burst switching (OBS). The paper presents a new contention resolution scheme, named as
adaptive parameter-based deflection routing
, which can control the deflection according to the time-varying traffic load and the QoS requirements. Compared with other schemes, the simulation results show that it can improve the overall
and the individual
of each class burst, and alleviate the offset-time deficit on QoS guarantee.
