Abstract: The present disclosure is directed to a network processor for processing high volumes of traffic provided by todays access networks at (or near) wireline speeds. The network process can be implemented within a residential gateway to perform, among other functions, routing to deliver high speed data services (e.g., data services with rates up to 10 Gbit/s) from a wide area network (WAN) to end user devices in a local area network (LAN).

Abstract: The Optical line terminal (OLT) tracks the number of data packets, bandwidth per user, and other data packet statistics. DDR (DRAM) is used to store the information tracked by the OLT. The DDR is accessed in a burst mode. In particular, the data is initially stored in an on-chip cache memory and then the data is sent periodically to the DDR in a burst mode. Leaky buckets can be used for each flow, and time stamps can be used to determine the last time the bucket was accessed.

Abstract translation: 光线路终端（OLT）跟踪数据包的数量，每个用户的带宽和其他数据包统计信息。 DDR（DRAM）用于存储由OLT跟踪的信息。 DDR以突发模式访问。 特别地，数据最初存储在片上高速缓冲存储器中，然后数据以突发模式周期性地发送到DDR。 泄漏桶可用于每个流程，时间戳可用于确定上次访问桶时。
