WebMux™ Overview
Key Features
The WebMux™ is a standalone network appliance designed primarily to load
balance IP traffic to multiple servers. The WebMux™ includes the following key
features.
•
Improves performance
by distributing the traffic for a site or domain
among multiple servers. No one server will be bogged down trying to
service a particular site.
•
SSL Termination
to reduce the cost of multiple certificates.
•
Provides high availability
by tracking which servers are functioning
properly and which servers are out of service. If a server unexpectedly
goes down, the WebMux™ will automatically re-direct the traffic to other
servers, or will bring a standby or backup server online to service the
traffic. The WebMux ™ does application level health check to many
network protocols on servers.
•
Provides Persistent Connections
by memorizing the user browser
session and the server session and sending the same user to the same
server. This is important for sites using shopping cart and dynamically
generated pages, like BroadVision, ASP and JSP sites.
•
Provides fault tolerance
. This installation requires two WebMuxes, a
primary and a secondary. The two WebMuxes will automatically sync the
configuration datum.
•
Easy management
. It can be managed via a secured web browser
session from anywhere in the world. By using https 128 bit encryption to
the management web console, secure remote management of server
farms is truly possible.
•
Operating System independent.
No software or agent to load on the
servers. Non-intrusive load/failure detection and management.
•
Provides Proxy function
. When communication is initiated from behind
the WebMux™, the WebMux™ will substitute its own address for the
internal address. This allows the web servers to initiate communication for
