Optical Packet/burst Switching

چکیده
In OBS, edge routers aggregate traffic into variable length bursts that are sent unslotted. This limits the amount of processing in the core routers. Header and data are seperated in time, by Toffset. This allows the switch to be correctly configured by the time the data arrives. The data burst can then pass through transparently. Since OBS is bufferless, Toffset decreases by δ in every node. Clearly Toffset > H⋅δ (H = number of hops, δ = header processing time).

Stochastic Analysis of Finite Population Bufferless Multiplexing in Optical Packet/Burst Switching Systems
In this letter, we study the blocking probabilities in an asynchronous optical packet/burst switching system with full wavelength conversion. Most of the existing work use Poisson traffic models that is well-suited for an infinite population of users. In this letter, the optical packet traffic arriving at the switching system is modeled through a superposition of a finite number of identical on...
متن کاملPerformance comparison between Optical Burst Switching and Deflection Routing
Optical packet-switched networks of the near future will likely use no or very small number of optical buffers. We compare the delay-throughput performance of deflection routing and optical burst switching because both do not require the use of optical buffers. Simulations show that the simple packet drop-andretransmit contention resolution strategy of optical burst switching has a better perfo...
متن کاملWavelength vs Burst vs Packet Switching: comparison of optical network models
In this paper Wavelength Switching (WS), Optical Burst Switching (OBS) and Optical Packet Switching (OPS) network models are compared. The next future is for WS networks but there is a big investigation effort for development of both OBS and OPS networks, which seem to be further successors in the optical networks world. At the beginning, a brief distinction between considered switching paradig...
متن کاملEnsuring QOS Guarantees in a Hybrid OCS/OBS Network
The bursting aggregation assembly in edge nodes is one of the key technologies in OBS (Optical Burst Switching) network, which has a direct impact on flow characteristics and packet loss rate. An optical burst assembly technique supporting QoS is presented through this paper, which can automatically adjust the threshold along with the increasing and decreasing volume of business, reduce the ope...
متن کاملAppendix A Architectures for optical packet and burst switches
Optical Packet Switching (OPS) and Optical Burst Switching (OBS) are optical networking concepts based on fully exploiting fast dynamic allocation of (D)WDM channels. Compared to more static approaches focusing on providing endto-end optical channels, OPS and OBS aim at providing greater bandwidth efficiency, granularity and flexibility. In this paper we give an overview of the issues arising w...
