`ABSTRACT
`(57)
`
`A method for deploying interactive applications over a
`
`
`
`
`
`
`
`network containing host computers and group messaging
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`servers is disclosed. The method operates in a conventional
`unicast network architecture comprised of conventional net-
`
`
`
`
`
`
`work links and 1] nicast gateways and routers. The hosts send
`
`
`
`
`
`
`
`
`
`
`messages containing destination group addresses by unicast
`
`
`
`
`
`
`
`to the group messaging servers. The group addresses select
`
`
`
`
`
`
`
`
`
`message groups maintained by the group messaging servers.
`
`
`
`
`
`
`
`
`For each message group, the group messaging servers also
`
`
`
`
`
`
`
`
`
`maintain a list of all of the hosts that are members of the
`
`
`
`
`
`
`
`
`
`
`
`
`
`particular group.
`In its most simple implementation, the
`
`
`
`
`
`
`
`
`method consists of the group server receiving a message
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`from a host containing a destination group addrcss- Using
`the group address, the group messaging server then selects
`
`
`
`
`
`
`
`
`
`a message group which lists all of the host members of the
`
`
`
`
`
`
`
`
`
`
`
`
`group which are the targets of messages to the group. The
`
`
`
`
`
`
`
`
`
`
`
`group messaging server then forwards the message to each
`
`
`
`
`
`
`
`
`
`of the target hosts. In an interactive application, many
`
`
`
`
`
`
`
`
`
`messages will be arriving at the group server close to one
`
`
`
`
`
`
`
`
`
`
`
`another in time. Rather than simply forward each message to
`
`
`
`
`
`
`
`
`
`
`its targeted hosts, the group messaging server aggregates the
`
`
`
`
`
`
`
`
`
`contents of each of messages received during a specified
`
`
`
`
`
`
`
`
`
`time period and then sends an aggregated message to the
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`targeted hosts. The time period can be defined in a number
`of ways. This method reduces the message traflic between
`
`
`
`
`
`
`
`
`
`hosts in a networked interactive application and contributes
`
`
`
`
`
`
`
`
`to reducing the latency in the communications between the
`
`
`
`
`
`
`
`
`
`hosts.
