Efficient neighbor channel reservation for contention resolution in optical burst-switched networks

We propose a different reflection-based technique, named efficient neighbor channel reservation, where a contending burst is reflected from a suitable neighbor node and then resumes its original path. Our proposed scheme does not use any extra hardware and addresses several limitations of other schemes including: (a) eliminating the use of bulky fiber delay lines, (b) avoiding complexity required with burst segmentation, (c) preventing resource wastage that occurs with prereservation schemes, and (d) preventing loop formation inherent in most deflection routing schemes.
