This paper evaluates several <i>O(log n)</i>-hop DHT (Distributed Hash Table) algorithms' suitability for interpersonal communications. DHTs have been widely used for file sharing, but recent research and standardization efforts are exploring their use for interpersonal communication as well. We identify the desired features of DHTs from the viewpoint of(More)
Structured Peer-to-Peer (P2P) networks, such as networks based on Distributed Hash Tables (DHTs), can be enhanced by using load balancing mechanisms. Current load balancing mechanisms are either trying to achieve even distribution of objects among nodes, make the address space as evenly populated as possible, or both. However, we have taken a different(More)
Today many Peer-to-peer (P2P) applications are widely used on the Internet. Especially file sharing is a popular P2P application that has, at least partially, replaced the centralized file sharing infrastructure. However, there are still a number of legacy applications that utilize a centralized infrastructure as opposed to a decentralized approach. In this(More)

We have studied the effect of head of the line blocking (HOLB) on session initiation protocol (SIP) session establishment delays. Our results are based on experiments performed in a test bed and on the public Internet. We used the stream control transmission protocol (SCTP) as a transport for SIP because SCTP can be configured to suffer or to avoid HOLB.(More)
