Báo Cáo Congestion control in mpls networks

Congestion control in mpls networksIP networks are widely used as a common platform between different operators, technologies and
applications. However, in IP networks, it is difficult to deploy effectively traffic engineering due to the
limitation capabilities of the IP technology. Also, they have some other drawbacks such as lack of QoS
guarantees, lack of security, etc. A new architecture has been proposed to offer traffic engineering
capabilities to the IP networks: Multi Protocol Label Switching (MPLS) [1,3]. Indeed, MPLS Traffic
Engineering has been widely deployed during the last few years and was motivated by the need for
congestion control, bandwidth optimization, fast recovery (MPLS TE Fast Reroute) and strict QoS
guarantees to carry sensitive traffic over multi-service packet networks. In this paper, FATE (Fast
Acting Traffic Engineering) and FATE+ mechanisms [2] have been considered as congestion control
methods, which are studied and effectively extended to solve the congestion problem and to re-balance
data streams through the core network.
