Embedded BGP Routing Monitoring

Previous studies ([7],[12]) explained a significant part of the BGP routing table growth in the Internet by the growth of specific operator practices like multi- homing and load-balancing. This article describes an embedded routing monitoring module aiming at detecting those practices, with the objective to help the router operator to better control BGP routing table size. The document first presents the motivations and the expected results of the study. Architecture of the routing monitoring module which has been prototyped are detailed, and results of experimentations are presented and analyzed. The article concludes with benefits and limitations of this approach, as well as ways this monitoring could be used to globally reduce BGP routing table thanks to route filtering.

A functional architecture for self-aware routers

In this paper, we first present the concept of self-configuration and self-provisioning applied into the scope of the IP routers. A global view of the concepts which are addressed in this document is given, considering the automation level of the operations, and their communication schemes. The node characteristics that are taken into account in the definition of self-configuration and self-provisioning mechanisms are also detailed, introducing the second part of the paper. In this part, a reference architecture for a self-configuration router is given, allowing the community to have a common understanding on the expected functionalities by such routers. An evaluation of the existing proposals to address part of all the issues raised by self-configuration is also presented.
