Questions tagged [bayeux]

Bayeux is a protocol for transporting asynchronous messages (primarily over HTTP), with low latency between a web server and a web client. The messages are routed via named channels and can be delivered: server to client, client to server, client to client (via the server).

The primary purpose of Bayeux is to support responsive bidirectional interactions between web clients, for example using using AJAX, and the web server.

Bayeux is a protocol for transporting asynchronous messages (primarily over HTTP), with low latency between a web server and a web client. The messages are routed via named channels and can be delivered:

  • server to client
  • client to server
  • client to client (via the server)

By default, publish subscribe routing semantics are applied to the channels.

Delivery of asynchronous messages from the server to a web client is often described as server-push.

The combination of server push techniques with an Ajax web application has been called Comet.

Bayeux seeks to reduce the complexity of developing Comet web applications by allowing implementors to more easily interoperate, to solve common message distribution and routing problems, and to provide mechanisms for incremental improvements and extensions.

See http://cometd.org/documentation/bayeux

Which are the benefits of Bayeux protocol compared to REST?

I've been using REST but I want more performance when working with large streams of data. Why does Bayeux protocol may be a better idea than REST? Which are the scenarios where Bayeux is the option? Doing research and working on a POC for now.
