Each Adaptive Server engine handles the network I/O for its connections. Engines are numbered sequentially, starting with engine 0.
When a user logs in to Adaptive Server, the task is assigned in round-robin fashion to one of the engines that is serving as the task’s network engine. This engine establishes the packet size, language, character set, and other login settings. All network I/O for a task is managed by its network engine until the task logs out.
