Process groups and group communications: classifications and requirements

Abstract

roup communication is an operating-system-level abstraction that offers convenience and clarity to the programmer. Currently, only a few To design a general, essarily one-to-one.) Each group is viewed as a single logical entity, without exposing its internal structure and interactions to users. operating systems support this abstraction. coherent, and integrated Generally, objects are grouped for (1) However, a lack of understanding of group abstracting the common characteristics of communication requirements with respect group communication group members and the services they proto different classes of applications may be vide, (2) encapsulating the internal state equally responsible for the abstraction's

Efficient multicast design in a microkernel environment

“…From our performance measurements and analysis we believe this is the best solution because it separates the semantics of multicast or group communication abstractions from the operating system support and mechanisms used to implement those abstractions. The former have been thoroughly investigated in [1][2][3][4], and the focus of this work is still an open issue. As explained in Section 3.1.1, our main concern in designing a multicast or group communication mechanism was efficiency.…”

“…The following classification and definitions are derived from a variety of sources, including [1][2][3]. Some of them map directly to existing systems, which are reviewed in Section 2.…”

Supporting persistent social groups in ubiquitous computing environments using context-aware ephemeral group service

“…Because device groups in a Ubicomp environment are ephemeral, they should be facilitated by a non-deterministic process group [10]. A group is defined to be deterministic if each member should receive and act on a request.…”

An experimental comparison of remote procedure call and group communication

“…Groups can be either closed or open [23]. In a closed group, only members can send messages to the group.…”
