摘　　要：文中主要介绍了一种自主设计的,基于现有PDH/SDH接口的,简单、灵活、低开销的速率自适应技术,适用于在相同物理接口形式互连的前提下,通过接口间的自动协商方式来确定传输的有效带宽,等效确定了接口速率的方法以及具体的协议实现。它的实现确保了接口之间自动进行可靠的互操作,因此不但简化了网络设备的操作性能,而且也提高了设备间组网时的智能性。An independent design on speed auto-negotiation technology of PDH/SDH interface is proposed,which is simple,flexible,and low-overhead. This technology is suitable for transfer bandwidth equal to speed confirmed through auto-negotiation and based on the same interface interlinkage. It could ensure reliable inter-operability between the interfaces,thus could simplify the operation of network device while raising the intelligence of device networking.
