Like traditional server farm, DHT-based server farm has high requirement on load balancing. Traditional solutions to balance load in DHTs either can not satisfy the requirement of server farm, or incur a high overhead. This paper presents a novel load balancing algorithm designed for server farm. Compared with the traditional virtual nodes algorithm, our algorithm generates the virtual IDs in the...
DHT (Distributed Hash Table) algorithms are very efficient for distributed data storage and retrieval. As one kind of P2P overlay, DHT overlay also has the advantages of high reliability, high scalability and low cost. DHT has not only been applied to form user nodes' overlays, but also been proposed to form DHT-based server farms, such as DHT-based SIP server farm, HSS server farm, DNS server farm,...
P2P systems can be used to form a low latency decentralized data delivery system. Structured P2P systems provide both low latency and excellent load balance with uniform query and data distributions, however, in the real application environment, requests distributions are often skewed and follow a Zipf law, some objects will become hotspots, individual nodes are easily overloaded, resulting in poor...
