The internet faces severe routing scalability problem - the rapid increasing of prefix and updates. There are two classes of factors that contribute to scalability problem: inappropriate allocation of IP addresses and inappropriate usage of them. Existing works mainly focus on inappropriate usage of allocations, so this work focuses on inappropriate allocation of IP addresses. We carry out the measurement...
Nowadays, due to the rapid growing popularity of Internet, the global routing system suffers from great scalability problem. Many solutions are proposed to solve the problem, including FIB aggregation, core/edge separation solutions, et al. The limitation of these existing solutions is that they all make the assumption that all addresses in the Internet must be globally visible and these routing information...
Nowadays, the global routing system suffers from great scalability problem. Core/edge separation solutions are proposed to solve the problem. However, they bring a global mapping system which might also suffer from scalability problem. We come up with an idea to reduce the necessary routing or mapping information, which is to separate content provider networks (containing content providers) from content...
Software-defined networking (SDN) is an emerging network architecture and OpenFlow is one of the representative works in SDN. As a possible approach towards future network, it has been introduced into a lot of application scenarios. Although SDN/OpenFlow have a lot of advantages, it is still debatable that whether they can manipulate a significant amount of real-life traffic when they are deployed...
The separation between edge and core addresses has been proposed to address the scalability problem of the Internet routing system. One main challenge is to design an efficient mapping mechanism for the two address spaces. The layer structure is attractive because of its scalability and simple index mechanism, while existing layered mapping system lacks a clear structure study and faces serious deployment...
