This paper proposes the technique of load balancing with traffic which is concentrated to MAP on the hierarchical mobile IPv6. This technique sends the secondary MAP address using the extension option of IPv6, so the upper level MAP will manage it. Therefore, when the overload occurs, it distributes the overload to the secondary MAP address by using redirect tunneling technique, so the efficient communication becomes possible. We validate the feasibility and result of the proposed technique by using ns-2 simulator.

This paper addresses the design of srTCM (single rate Three Color Marker) described in RFC2697. It has proposed for srTCM to be used at the ingress of Differentiated Service network that provides AF PHB (Assured Forwarding Per Hop Behavior). srTCM 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). This paper designs srTCM function and then implements it in one chip using VHDL and FPGA technology.
