# Routed Queues

With respect to routing, queues differ from topics in several respects.

These differences can be summarized as:

- Servers route queue messages between the queue owner and adjacent servers.
- The concept of zones and hops does not apply to queue messages (only to topic messages).

The left side of the following image depicts an enterprise with three servers—P, R and S—connected by routes. The remainder of the image illustrates the mechanisms that routes queue messages among servers (center) and their clients (right side).
