摘要： A buffer management system for cooperating with a packet based switching system is proposed. The purpose of this system is to reduce traffic congestion, ameliorate its effects, provide fairness to each data source, and to increase functionality while respecting advantageous system characteristics. Fabric output buffers include an arbitration function, a quality of service function, and are associated with individual routing tables. The system uses shallow logic that allows for single clock cycle operation even at high clock speeds. In order to provide for system control of bandwidth, sources with bandwidth practices counter to system interests are addressed. Where there is a conflict of sources over a resource, the buffer management system arbitrates traffic to resolve conflicts in a timely manner while fairly allocating traffic share using a weighted round robin arbitration scheme.

摘要翻译： 提出了一种用于与基于分组的交换系统协作的缓冲器管理系统。 该系统的目的是减少交通拥堵，改善其影响，为每个数据源提供公平性，并且在尊重有利的系统特性的同时增加功能。 结构输出缓冲器包括仲裁功能，服务质量功能，并且与各个路由表相关联。 该系统使用浅逻辑，即使在高时钟速度下也允许单时钟周期操作。 为了提供带宽的系统控制，解决了具有与系统兴趣相抵触的带宽做法的源。 在资源上存在资源冲突的情况下，缓冲区管理系统会以及时的方式对流量进行仲裁以解决冲突，同时使用加权循环仲裁方案公平分配流量共享。
