Tesis doctoral de Marcelo Yannuzzi Sanchez
One of the most complex problems in computer networks is how to provide guaranteed performance and reliability to the communications carried out between nodes located in different domains. This is due to several reasons — which will be analyzed in detail in this thesis — but in brief, this is mostly due to: i) the limited capabilities of the current inter-domain routing model in terms of traffic engineering (te); ii) the distributed and potentially conflicting nature of policy-based routing, where routing policies are managed independently and without coordination among domains; and iii) the clear limitations of the inter-domain routing protocol, namely, the border gateway protocol (bgp). the goal of this thesis is precisely to study and propose solutions allowing to drastically improve the performance and reliability of inter-domain communications. One of the most important tools to achieve this goal, is to control the routing and te decisions performed by routing domains. Therefore, this thesis explores different strategies on how to control such decisions in a highly efficient and accurate way. at present, this control mostly resides in bgp, but as mentioned above, bgp is in fact one of the main causes of the existing limitations. The natural next-step would be to replace bgp, but the large installed base at present together with its recognized effectiveness in other aspects, are clear indicators that its replacement (or its possible evolution) will probably be gradually put into practice. in this framework, this thesis proposes to to study and contribute with novel strategies to control the routing and te decisions of domains in three different time frames: i) at present in ip multi-domain networks; ii) in the near-future in ip/mpls (multiprotocol label switching) multi-domain networks; and iii) in the future optical internet, modeling in this way a realistic and progressive evolution, facilitating the gradual replacement of bgp. more specifically, the c
