PAINT: Partial in-network transcoding for adaptive streaming in information centric network
2014
2014 IEEE 22nd International Symposium of Quality of Service (IWQoS)
Preserved Fulltext
The problem is, each ICN node caches duplicated copies of the same content for each bitrate version in its limited storage space. ...
Thus the cache hit ratio drops, and the bandwidth cost of serving the cache missed requests increases. ...
Table IV lists all the bitrate levels of a content in a real adaptive streaming system [27] . Based on these settings, we have R = 5, B h = 1.5M b, B sum = 4.6M b, B m = 0.775M b. ...
