    摘要： Multiple users participate in a conference while taking maximum advantage of hardware and bandwidth capabilities of each participant. Each user's system makes known to a directory service its hardware sending and receiving capabilities. The directory service makes this information available to other users who may then wish to join a conference with the user. An initiating user sends invitations via the directory service to the remote users. Each user that accepts an invitation transmits its network address to the initiating user, who then establishes a peer-to-peer connection with each of the remote users. Each participant system exchanges information about hardware capabilities and bandwidth, and a conference manager determines a best model for connecting each of the participants. Depending on the hardware and bandwidth capabilities of the participants, the manager chooses from a duplicate streams model, a multicast model, and a host-among-peers model for connecting the participants.

    摘要翻译： 多个用户参与会议，同时最大限度地利用每个参与者的硬件和带宽功能。 每个用户的系统使目录服务知道其硬件发送和接收能力。 目录服务使此信息可供其他用户使用，然后可能希望与用户加入会议。 发起用户通过目录服务向远程用户发送邀请。 接受邀请的每个用户将其网络地址发送给发起用户，然后他们与每个远程用户建立点对点连接。 每个参与者系统交换关于硬件能力和带宽的信息，会议管理器确定连接每个参与者的最佳模型。 根据参与者的硬件和带宽能力，管理员从重复流模型，组播模型和对等主机模型中选择连接参与者。
