Recently, many IXes (Internet eXchanges) exist in the world. IX is a mechanism, to interconnect many networks to each other. An ISP establishes and maintains numerous interconnections to other ISPs via an IX. Currently, two major IX architectures exist. One uses LAN (Local Area Network) technologies such as FDDI, Ethernet or Gigabit Ethernet to interconnect ISPs to each other. The other IX architecture is based on ATM (Asynchronous Transfer Mode) technology, which uses PVCs (Permanent Virtual Circuit) between participating ISPs. Both LAN and ATM based IXes have several problems,for example, bandwidth limitation, operational cost, less scalability, and dependency on data-link mediums. In this paper, we propose a next generation IX architecture based on MPLS (Multi-Protocol Label Switching) technology. MPLS is a new routing paradigm and provides abstraction of network devices. MPLS provides virtual paths, called LSP (Label Switched Path), between MPLS capable routers and hide physical or data-link medium dependency for actual data transmission. We apply the MPLS technology to an IX. A MPLS based IX has the advantages of the independency on data-link mediums, unliminted bandwidth, scalability, and widely distributed features.
