摘要： A load reduction dual in-line memory module (LRDIMM) is similar to a registered dual in-line memory module (RDIMM) in which control signals are synchronously buffered but the LRDIMM includes a load reduction buffer (LRB) in the data path as well. To make an LRDIMM which appears compatible with RDIMMs on a system memory bus, the serial presence detector (SPD) of the LRDIMM is programmed with modified latency support and minimum delay values. When the dynamic read only memory (DRAMs) devices of the LRDIMM are subsequently set up by the host at boot time based on the parameters provided by the SPD, selected latency values are modified on the fly in an enhanced register phase look loop (RPLL) device. This has the effect of compensating for the delay introduced by the LRB without violating DRAM constraints, and provides memory bus timing for a LRDIMM that is indistinguishable from that of a RDIMM.

摘要： Methods and apparatus are disclosed for using gap packets to create a bandwidth buffer over which packets can be sent to reduce or eliminate overflow conditions. One implementation sends a series of packets from a first device to a second device, the series of packets including interspersed information packets and gap packets. The first device determines when to insert the gap packets into the series of packets, and the gap packets received by the second device are dropped. The determination of when to insert one of the gap packets into the series of packets may be based on an occupancy level of a buffer, such as, but not limited to comparing it to a predetermined or variable threshold value. Also, the rate of sending gap packets and/or the size of the gap packets may be varied to adjust the size of bandwidth buffer created by the gap packets.

摘要： Methods and apparatus are disclosed for identifying the relevancy of packets. In one embodiment, source addresses are associated with network topology indications. When a packet is received, its network topology indication is compared with the corresponding one retrieved from a data structure to determine whether to drop the packet. Source addresses may also be associated with authorized interfaces to determine whether a packet was received on an authorized interface. In one embodiment, a maintained network topology indication is associated with a packet. After it is processed, the corresponding latest network topology indication is retrieved and compared with that previously associated with the packet. In one embodiment, upon a change in a network topology indication associated with an interface, control packets are placed in each of the queues corresponding to the destination interface, so it can be readily identified when this update has been propagated through the system.
摘要翻译：公开了用于识别分组的相关性的方法和装置。在一个实施例中，源地址与网络拓扑指示相关联。当接收到分组时，将其网络拓扑指示与从数据结构检索到的相应的一个比较，以确定是否丢弃分组。源地址也可以与授权接口相关联，以确定在授权接口上是否接收到分组。在一个实施例中，维护的网络拓扑指示与分组相关联。处理后，将检索相应的最新网络拓扑指示，并将其与之前与数据包相关联的指标进行比较。在一个实施例中，在与接口相关联的网络拓扑指示的改变中，控制分组被放置在与目的地接口相对应的每个队列中，因此当该更新已经通过系统传播时，可以容易地识别。

摘要： A central station of a cable television distribution network transmits TDM frames comprising distribution information and overhead information downstream to customer terminals, and determines corresponding upstream TDMA frames by including an upstream frame identity in the overhead information of each downstream frame. Each terminal buffers asynchronous information for upstream transmission, and stores an upstream frame identity which it is assigned. On detecting this frame identity in the downstream overhead information, the terminal transmit a buffer queue size in an assigned time slot of the corresponding upstream frame. The central station uses the queue sizes from the terminals to allocate time slots in the upstream frames to terminals, by including their terminal addresses in the downstream overhead information, for transmission of the buffered asynchronous information. The central station can also assign time slots to the terminals for transmission of isochronous information.
摘要翻译：有线电视分配网络的中心站向客户终端发送包含分发信息和开销信息的TDM帧，并通过在每个下行帧的开销信息中包括上游帧标识来确定相应的上行TDMA帧。每个终端缓存用于上行传输的异步信息，并存储其被分配的上行帧标识。在下行开销信息中检测到该帧标识时，终端在相应上游帧的分配时隙中发送缓冲器队列大小。中心站使用来自终端的队列大小，通过将终端地址包括在下游开销信息中，将上行帧中的时隙分配给终端，以便发送缓冲的异步信息。中心站还可以向终端分配时隙以传输等时信息。
