Horde: Flexible Network Striping

Horde is linux-based networking middleware that allows an application to stripe data from multiple streams across a set of dissimilar wireless network channels. Horde's approach aims to decrease the programming costs associated with building complex mobile systems that use network striping.


Horde provides a robust way for multi-stream applications to communicate over multiple channels with widely varying latency and bandwidth. It attempts to separate the striping mechanism from the striping policy, the latter being specified at run-time by the application in an abstract manner. In this way, in addition to aggregating bandwidth, Horde allows applications to modulate network QoS for their streams.


We have been using Horde to stripe video over multiple CDMA2000 EV-DO channels, so the current development code is optimized for this scenario.
