MSTP多业务平台技术基于SDH同步传输系统技术,同时为以太网业务、ATM业务提供便捷接入。以思科ONS 15454 MSTP设备为例,介绍了MSTP设备在高速率传输带宽上为数据网提供传统的POS和E1串口接入方式之外,还提供了丰富的EOS接入方式,MSTP具有构建强大VLAN嵌套的QinQ功能、构建城域RPR网功能、构建MPLS VPN等路由功能,使传统的光传输技术与TCP/IP的业务逐步融合。

MSTP multi-service platform technology is based on SDH synchronous transmission system technology,at the same time it provides convenient access to Ethernet service and ATM services.By taking Cisco ONS 15454 MSTP as an example,the paper introduces that the MSTP equipment in high rate transmission bandwidth for data network provides traditional POS and E1 serial access mode,it also provides a rich EOS access modes.MSTP is provided with powerful function of VLAN nested QinQ,constructing metropolitan area RPR network,constructing routings like MPLS VPN,enabling traditional optical transmission technology to integrate with services of TCP/IP step by step.
