On Consistency and Network Latency in Distributed Interactive Applications: A Survey—Part II

This paper is the second part of a two part paper that documents a detailed survey of the research carried out on consistency and latency in distributed interactive applications (DIAs) in recent decades. Part I reviewed the terminology associated with DIAs and offered definitions for consistency and latency. A classification for consistency maintenance mechanisms was given and various mechanisms belonging to the first of three categories, time management, were described. Here, in the second part of the paper, the remaining two categories of mechanisms are examined—information management (such as predictive contract techniques, relevance filtering, packet bundling) and system architecture (such as QoS and protocols).
