Modeling of Web server replication system in MPLS networks

Internet and World Wide Web is now a popular mean of interaction among people, institutions, and corporations from all over the world. In order to overcome problems of Internet development techniques of caching and replication are deployed. In this work we address problems of modeling replica system in MPLS (Multiprotocol Label Switching) environment. MPLS is a new, evolving connection oriented technique for IP networks. We present and discuss issues of Web replica systems and MPLS technology. We propose two new optimization models of Web replica system using MPLS.
