Chen Bin, Wang Hui, Su Gongchao. Access mechnism-based differentiated service in IP/MPLS over WDM networks[J]. 2009,(3):14-17. DOI: 10.13756/j.gtxyj.2009.03.010.
the optical network can dynamically provide the IP network with bandwidths by setting up a new lightpath.It is an important goal for traffic grooming to maximize the profit of the service provider by utilizing the limited resources of the optical network.In this work
on the basis of the overlay network model
we study the access mechanism for the IP/MPLS over WDM networks and try to develop an algorithm that can provide differentiated services to them without impacting the overall network efficiency.
