A novel optical burst switching architecture for high speed networks

引用

Chinese Optics Letters 2008年第11期6卷 807-811页

作者： Amit Kumar garg R.s.Kaler school of Electronics and Communication Engineering Shri Mata Vaishno Devi University (J and K)India Department of Electronics and Communication Engineering Thapar University (Punjab)India

A novel optical burst switching （OBs） high speed network architecture has been proposed. To verify its feasibility and evaluate its performance, just-enough-time （JET） signaling has been considered as a high performance protocol. In the proposed architecture, to avoid burst losses, firstly, a short-prior- confirmation-packet （sPCP） is sent over the control channel that simulates the events that the actual packet will experience. Once sPCP detects a drop at any of the intermediate nodes, the actual packet is not sent but the process repeats. In order to increase network utilization, cost effectiveness and to overcome some limitations of conventional OBs, inherent codes （e.g., orthogonal optical codes （OOC））, which are codified only in intensity, has been used. Through simulations, it shows that a decrease in burst loss probability, cost effectiveness and a gain in processing time are obtained when optical label processing is used as compared with electronic processing.

Performance analysis of an integrated scheme in optical burst switching high-speed networks

引用

Chinese Optics Letters 2008年第4期6卷 244-247页

作者： Amit Kumar garg R.s.Kaler school of Electronics and Communication Engineering shri Mata Vaishno Devi University(J and K) India school of Electronics and Communication Engineering Thapar University Patiala PunjabIndia

A new integrated scheme based on resource-reservation and adaptive network flow routing to alleviate contention in optical burst switching networks is proposed. The objective of the proposed scheme is to reduce the overall burst loss in the network and at the same time to avoid the packet out-of-sequence arrival problem. simulations are carried out to assess the feasibility of the proposed scheme. Its performance is compared with that of contention resolution schemes based on conventional routing. Through extensive simulations, it is shown that the proposed scheme not only provides significantly better burst loss performance than the basic equal proportion and hop-length based traffic routing algorithms, but also is void of any packet re-orderings.
