Super Chunk Abstruct


Superchunk - based efficient search in P2P-VOD schemes

Aim
The main condition of this project is to provide reliable and fast content husking in friend-to-peer (P2P) video-on-demand (VOD) system to enable user interactivity under peer dynamics.

Synopsis
Peer to Peer (P2P) system has emerged as a vivid technology to provide video-on-demand (VOD) service.
Superchunk-based efficient search Net break down(SURFNet). SURFNet divides mental pictures into superchunks and chunks. Stable peers that be likely to have longer life spans in the system are used to construct an AVL tree to provide superchunk-level entropy availability information. Peers storing the same superchunk are grouped into a holder-chain, which is therefore attached to a node in the AVL tree. This structured get across is consists of only stable peers, it provides a reliable backbone tear down in highly dynamic environment.

Existing System
Since SURFNet adopts an AVL tree for superchunk search, we tense up the difference between SURFNet and existing AVL tree-based schemes. In an Existing uncrystallised overlay is used to discover chunks and we use gossip manner in this peers exchange data availability information periodically with neighbors and select which neighbor to download from based on this information.

However, when a seek is performed and the required data is not available at any neighbors, it may take a long measure to find the data. Moreover, gossip method introduces nontrivial overhead.
PPLives solution to this is to deploy centralized trackers to index which peers replicate a given movie and only use gossip method for intra-movie information discovery. Although tracker thunder mug speed up a search, we do not dole out centralized solution as it introduces a single contingent of failure and may become a bottleneck of the system.

Proposed System
Our work is different from the existing content discovery schemes for storage-forwarding systems in the pastime:
1) We integrate a structured overlay with gossip protocol, which shadower provide...If you want to get a full essay, order it on our website: Orderessay
