Resource Allocation for Optical Packet-switching Routers with Self-similar Bursty Traffic
[chapter]
2001
IFIP Advances in Information and Communication Technology
Preserved Fulltext
This paper addresses the problem of resource allocation in optical packetswitching routers under self-similar bursty Internet traffic conditions. ...
Our findings suggest that selfsimilar traffic significantly increases the resource requirement compared with similar studies performed using traditional bursty traffic models. ...
