设计了一个多吉比特（Ｍｕｌｔｉ－ｇｉｇｎｂｉｔｓ）全双工并行光纤环网──ＰａｒａＮＥＴ网络，它的峰值传输速率为４．８Ｇｂｐｓ，吞吐能力达２０Ｇｂｐｓ，可有效地支持点到点Ｍｕｌｔｉ－ｇｉｓａｂｉｔｓ的实时信息传输与交换。ＰａｒａＮＥＴ采用并行缓冲器插入技术，结点（ＡＮ）内ＦＩＦＯ队列流水操作，减少了信元缓冲时延。多业务队列模型支持不同优先级服务，形成各种虚拟逻辑子环，根据业务负荷动态分配网络的带宽资源，提供Ｂ－ＩＳＤＮＱＯＳ保证。ＰａｒａＮＥＴ通过并行网络处理提供分布式实时ＡＴＭ交换能力，结点内低速化（４０Ｍｂｐｅ）并行操作仅需现有的ＴＴＬ和ＣＭＯＳ技术，使网络的实现经济并提高了可行性。本文给出了ＰａｒａＮＥＴ并行环同的系统结合设计，描述了网络纺问结点的模块功能，详细讨论了并行缓冲器插入及不等读／写脉宽调制技术，并对环网的信元延迟特性进行了计算。
Designed a multi-gignbits full-duplex parallel optical fiber ring called Paranet network with peak transmission rate of 4.8Gbps and throughput of 20Gbps, effectively supporting the real-time information of point-to-point Multi-gisabits Transmission and exchange. ParaNET uses parallel buffer insertion technology, FIFO queue watering operation in node (AN), reducing cell buffer delay. Multi-service queue model to support different priority services, the formation of a variety of virtual logical sub-ring, according to the business load dynamically allocated network bandwidth resources, to provide B-ISDNQOS guarantee. ParaNET provides distributed, real-time ATM switching capabilities through parallel network processing, and low-speed (40Mbpe) parallel operation within the node requires only existing TTL and CMOS technologies to make the network economical and viable. In this paper, ParaNET parallel ring system design is given, the module function of the network spinning node is described, parallel buffer insertion and unequal read / write pulse width modulation are discussed in detail, and the cell delay The characteristics were calculated.
