An experimental prototype of an IP router, interconnecting standard Ethernet LANs by means of ATM networks, is presented. The suite of ATM protocols up to the SAR sublayer has been implemented partially in hardware and partially in software. In particular, the physical layer is implemented in hardware with a data rate of 155.520 Mbps while the other functions are software based. The global throughput for this implementation can be up to 6-8 Mbps, fast enough for the considered context. An upgrade of the design is presented where most of the functions up to the AAL protocol are hardware based. The throughput of this upgraded architecture is expected to improve considerably up to several tens of Mbps.

Abstract

An experimental prototype of an IP router, interconnecting standard Ethernet LANs by means of ATM networks, is presented. The suite of ATM protocols up to the SAR sublayer has been implemented partially in hardware and partially in software. In particular, the physical layer is implemented in hardware with a data rate of 155.520 Mbps while the other functions are software based. The global throughput for this implementation can be up to 6-8 Mbps, fast enough for the considered context. An upgrade of the design is presented where most of the functions up to the AAL protocol are hardware based. The throughput of this upgraded architecture is expected to improve considerably up to several tens of Mbps.
