Combining Intelligent Route Control with Backbone Traffic Engineering to Deliver Global QoS-Enabled Services



A global quality of service enabled Internet requires standard mechanisms to support the inter-autonomous systems quality of service connection. Two core components of the required functionality are the quality of service-enabled Border Gateway Protocol and the off-line backbone Traffic Engineering. Each of these approaches is, by itself, rather limited. Although the first enables the propagation of quality of service related messages and the latter potentially helps to improve the end-to-end quality of service, they both fail to achieve fast reaction to topology or path quality changes, as well as to users’ requirements. Existing solutions have shown that these limitations can be partially addressed by employing Intelligent Route Controllers at multi-homed stub autonomous systems. Unfortunately, the ability of both parties, i.e., stub autonomous systems and Internet Service Providers, to choose their own routing policies does not necessarily lead to the best routing of IP packets in the Internet. In effect, each party seeks to control its traffic according to its own goals without considering the effects over the traffic or network of the other party. In this chapter the integration of Intelligent Route Controllers and off-line Traffic Engineering mechanisms is proposed to overcome the identified issues. The results show that this combination can produce synergistic interactions between Intelligent Routing Control and Traffic Engineering.
