Unveiling the MPLS Structure on Internet Topology

چکیده
Recently, researches have been conducted to discover and assess the usage of MPLS tunnels. Indeed, recent developments in the ICMP protocol make certain categories of MPLS tunnels transparent to traceroute probing. Additional techniques have been proposed to reveal the presence of MPLS tunnels when they do not explicitly appear in traceroute. It has been shown that MPLS is a very well deployed technology whose usage (i.e., Traffic Engineering, load balancing, etc.) varies in time and according to ASes. However, the MPLS structure on the Internet architecture has not been studied yet. In this paper, we follow this path by providing two contributions to the state of the art: (i) we evaluate the biases involved on MPLS tunnel detection when they are not directly revealed through traceroute. (ii), we provide some properties and architectural details related with MPLS deployment on router topology based on a k-core decomposition.

Fast Recovery of MPLS Paths
A new general theory about restoration of network paths is first introduced. The theory pertains to restoration of shortest paths in a network following failure, e.g., we prove that a shortest path in a network after removing k edges is the concatenation of at most k + 1 shortest paths in the original network. The theory is then combined with efficient path concatenation techniques in MPLS (mul...
متن کاملMPLS-BGP based LSP setup techniques
Internet routing is based on a distributed system composed of many routers, grouped into management domains called Autonomous Systems (ASes). Routing information is exchanged between ASes using Border Gateway Protocol. When BGP is used to distribute a particular route, it can be also be used to distribute an MPLS label which is mapped to that route. In this paper the comparison of conventional ...
