IB - Reliable Multicast Transport protocol

Goals

To use idle bandwidth to pre-load caches with objects that might be of interest in the future.

The workstation and network resources may be idle when the user is browsing the page. The idea is to make use of available bandwidth (if any)

Use offline mechanism i.e repair request is send only if data is requested by someone. The cache knows everything that is missing and could make a single request for that.
