JGroups is a reliable multicast system written in the Java language. JGroups adds a "grouping" layer over a transport protocol, internally keeping a list of participants. This list is used to: * Make the application aware of the listeners * Make some or all transmissions reliable * Allow totally ordered transmissions JGroups is a toolkit for reliable multicast communication. It can be used to create groups of processes whose members can send messages to each other. JGroups enables developers to create reliable multipoint (multicast) applications where reliability is a deployment issue. JGroups also relieves the application developer from implementing this logic themselves. This saves significant development time and allows for the application to be deployed in different environments without having to change code. ==JGroups Features== * Group creation and deletion. Group members can be spread across LANs or WANs * Joining and leaving of groups * Membership detection and notification about joined/left/crashed members * Detection and removal of crashed members * Sending and receiving of member-to-group messages (point-to-multipoint) * Sending and receiving of member-to-member messages (point-to-point) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「JGroups」の詳細全文を読む スポンサード リンク
