The dispensing mechanism of active code is the key technology in active network. Conventional capsule and programmable switch approaches have their own shortcomings. DCCAN mechanism presented in this paper overcomes their shortcomings. In this paper, capsule and programmable switch approaches are introduced and their shortcomings are analyzed. The principle of DCCAN mechanism is described. The theoretical analyses in transmission bandwidth based on DCCAN mechanism and capsule approach are described, and key factors which affect the transmission bandwidth based on DCCAN mechanism are also discussed. At the same time, the theoretical analyses in latency based on DCCAN mechanism and capsule approach are described. The using condition of DCCAN mechanism is also discussed.
