Towards a Novel Architecture for Wide-Area Data Caching and Replication
نویسندگان
چکیده
Caching and Replication play a critical role in alleviating network latency and server load. In this paper, we propose an Active Networks based architecture for improving caching/replication that operates by obtaining statistics from the network nodes to identify hot-spots in client access patterns. The objects are endowed with the intelligence to make their own replication decisions based on the access statistics. Existing schemes such as hierarchical proxy servers and DNS based server load balancing are not designed to the geographical and temporal spikes in user demand. Thus there is a clear need for schemes that are scalable and

A Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...

متن کاملMiddleware Support for Locality-aware Wide area Replication
Coherent wide-area data caching can improve the scalability and responsiveness of distributed services such as wide-area le access, database and directory services, and content distribution. However, distributed services differ widely in the frequency of read/write sharing, the amount of contention between clients for the same data, and their ability to make tradeoffs between consistency and av...
متن کاملA Study of Ingredients Affecting the Private Sectures Inclination Towards Housing Supply
Just like any other economic field, housing market has two basic foundations which are demand and supply. Its obvious that disequilibrum between these foundations, will drasticaly affect the housing affordability and can also lead to wide slump in many markets. That’s why, policy makers usually intend to stimulat the supply by means of providing low intrest loans, low priced land, etc. In this ...
متن کاملConfigurable Consistency for Wide-area Caching
Data caching is a well-understood technique for improving the performance and availability of wide area distributed applications. The complexity of caching algorithms motivates the need for reusable middleware support to manage caching. To support diverse data sharing needs effectively, a caching middleware must provide a flexible consistency solution that (i) allows applications to express a b...
