| 单词 | strength member |
| 释义 | strength member signal within the core conductors, thereby reducing signal loss and maintaining signal strength over a longer distance. Screened twisted pair (ScTP) is a simpler version with only an outer shield. See also Cat 6, Cat 7, ScTP, and UTP. 2. Signal Transfer Point. In the advanced intelligent network architecture (AIN) architecture, a packet switch that routes signaling and control messages between a service switching point (SSP) and a service control point (SCP), and between STPs. See also AIN, packet, SCP, signaling and control, SSP, and switch. 3. Spanning Tree Protocol. A bridge protocol for learning bridges, as defined in IEEE 802.1D standards. Spanning tree bridges are self-learning, filtering bridges for use in connecting LANs or LAN segments on a point-to-point basis.The bridge can be programmed or can teach itself the addresses of all devices on the network; subsequently, the network tree of the bridge provides only one span connection. Some spanning tree bridges also have the capability to provide security by denying access to certain resources based on user and terminal ID. Bridges that support the spanning tree algorithm have the ability to automatically reconfigure themselves for alternate physical paths if a network segment fails, thereby improving overall reliability. Radia Perlman invented STP while working for Digital Equipment Corporation (DEC). See also algorithm, bridge, filtering bridge, LAN, path, protocol, segmentation, and self-learning bridge.
