【摘要】 本文介绍了一种新型同步时隙快速分组交换环网（ＳＦＰｒｉｎｇ）及其特性。此网通过对时隙环增加环路帧同步器的方法，使得环路的时隙一致，简化环路接口，虽使时隙环在低负荷下延时特性略有下降，但由子能采用分组目的站回收方案，可使其重负荷条件下效率提高一倍，因而其十分适于综合业务局域数字网。更多还原

【Abstract】 This paper presents a new isochronous slotted fast packet switch ring network(SFPring) and its characteristics. By adding frame synchronizer, the ring works in synchronized slot and is simple in network interfaces. Though the delay characteristics is degraded alittle compared with the normal slot ring in light traffic, by recycling the packets in the destination station, the ring gains doulbe efficiency in the heavy traffic and fits the needs of intergrated local areas digtal network更多还原
