Hi. ns-users: I want to apply processing delay to an agent. Agent works like: 1. receive a packet 2. make new packets and send them 3. do nothing during processing delay 4. back to 1. (process next packet) I used Timer, but it causes a problem that the agent can receive a packet and send new packets before timeout. Does anyone know how to solve this problem? Thanks in advance. --Yukio HASHIMOTO
