Abstract

This paper addresses the design of trTCM (Two Rate Three Color Marker) described in RFC2698. It has proposed for trTCM to be used in Differentiated Service network that provides AF PHB (Assured Forwarding Per Hop Behavior). trTCM is the marker with the metering function, and consists of the token updating function and the marking function. The token updating function uses the dual token bucket. The marking function compares the token values with the length of input packet and then marks the result into IP QoS field (ToS field). In this paper, we design trTCM function and then addresses the scheme to implement it using FPGA technology.

본 논문은 RFC2698에서 제안하고 있는 trTCM(Two Rate Three Color Marker)를 디자인 한 것이다. 그것은 trTCM을 AF PHB (Assured Forwarding Per Hop Behavior)을 제공하는 DS 네트워크에서 사용할 것을 권고하고 있다. trTCM은 미터링 기능을 가진 마커이며, 토큰 갱신 기능과 마킹 기능으로 구성되어 있다. 토큰 갱신 기능은 듀얼 토근 버킷을 가지고 있다. 마킹 기능은 토큰 값을 입력 패킷의 길이와 비교한 후 그 결과를 IP QoS 필드에 마킹 한다. 본 논문에서는 trTCM 기능을 디자인 하였고, FPGA를 이용하여 그 기능을 구현하는 방안을 언급하였다.
