Deploying MPLS on the Czech Academic Backbone

Ladislav Lhotka, University of South Bohemia, Czech Republic

This paper describes the process of migrating the Czech Academic backbone from LAN emulation to Multiprotocol Label Switching (MPLS). The network is large enough to serve as a proof of the MPLS concept. After explaining the reasons for this migration, the national ATM network topology is described and the main principles and features of the new MPLS architecture are discussed. During the practical deployment, several problems (mainly software bugs) of varying severity were observed which are classified into four main categories in the paper. It is concluded that MPLS is a viable technology even though its deployment in large backbone networks with heavy traffic may still be rather troublesome with many serious problems that do not show up in laboratory or other experimental setups.
