The result of this is of course that ntl save on upstream capacity on the cable network. You aren't uploading because a caching server is doing your uploading for you. You aren't costing them as much in off-network traffic as you're doing at least some of your downloading from the caching server.

Traffic shaping in this instance can eliminate the need to use WCCP or another load balancing protocol, the traffic shaping kit can transparently redirect your traffic to the caches to achieve the above results.
