Routing, L2 Addressing, and Packet Filtering in a Hardware Engine
Original language description
To improve throughput of personal computers used as Internet routers, hardware acceleration can be used. Packet classification unit employed in the design utilizes content addressable memory combined with comparison instructions. Routing, link layer addressing, and packet filtering has to be performed in a single operation. We have developed a representation of the first two called routing-ARP table, and representation of filters based on decision diagrams. In this paper, we describe a method to combinethem all together and convert the resulting structure into the hardware device. As a special case, the algorithm converts a decision diagram into a first-match structure. Dealing with implementation and limited hardware resources is mentioned.

Směrování, L2 adresace a filtrace paketů v hardwarovém akcelerátoru
Czech description
Pro zlepšení propustnosti osobního počítače použitého jako směrovače lze použít hardwarovou akceleraci. Jednotka pro klasifikaci paketů používá CAM kombinovanou s porovnávacími instrukcemi. Směrování, L2 adresace a filtrace paketů musí být provedena v jediné operaci. Článek popisuje kombinaci směrovací-L2 tabulky a filtru do struktury vhodné pro hardwarovou jednotku.
