Super Sparrow enables users to load balance traffic between geographically separated points of presence by finding the site network-wise closest to clients. This is done by accessing BGP routing information, the information that determines the path that traffic will take on the internet.

Super Sparrow forms part of VAnessa. Super Sparrow is designed to work with other components of VAnessa, including Ultra Monkey.

Key Features:

Uses BGP routing information to determine which point of presence a client should connect to.
Routing information can be obtained from a Route Server running GNU Zebra, Gated or Cisco IOS.
Driver module, mod_supersparrow, for Dents enables Super Sparrow enhanced sites to used DNS to communicate which server a client should connect to.
Stand-alone programme, supersparrow, enables Super Sparrow to be integrated into applications that can communicate using stdio. This can be used to tie Super Sparrow directly into The Apache HTTP Server.
Library API to enable applications to be integrated with Super Sparrow.
Code is Open Source.
