Abstract:

In order to solve the problem that the communication overhead of date update was too large on network-coding-based cloud storage system,a new differential data update scheme was proposed.By encoding and compressing the updated part of file,the communication overhead was reduced significantly.A network-coding-based storage prototype system was designed and implemented,and update scheme was deployed in the real network settings.Experimental results show that the proposed scheme has less communication overhead and better scalability than the existing schemes.

Key words: network coding, cloud storage, differential data update
