Especially no additional cost exists if services have started before the network topology is formed, except the size of control packets grows.

特别是当节点加入网络之前服务已经启动时，除了控制报文大小的变化以外，不会造成额外的控制开销。

On the platform of IEEE 802.11, the realizable scheme is proposed by introducing the self-organized algorithm and designing management packets, control packets, and data packets of UTPMA.

在IEEE 802.11标准的平台上，提出了UTPMA协议的实现方案，描述了UTPMA协议的网络自组织算法，并设计了协议的管理、控制、数据分组的结构。
