Abstract: An apparatus is provided that includes n communication channels, and m communication media interfaces, and v virtual lanes. V is a positive integer multiple of the least common multiple of m and n. An information stream is transferred into data and alignment blocks striped across all of the v virtual lanes, the blocks being communicated from the virtual lanes onto the communication channels. The blocks are received on the communication channels. Each of the communication channels transmits a different portion of the blocks striped across all of the v virtual lanes.In more particular embodiments, v>=n>=m. The communication media interfaces can be electrical and optical. Each of the communication channels can include a SerDes interface operating at least 5 Gigabits per second. Furthermore, each of the m communication media interfaces is configured to transmit a different stream of information over a single optical fiber.

Abstract: In one embodiment, a method for communicating a sequence of data bits is provided. FEC coding is performed on a received sequence of data bits to produce an FEC coded sequence formatted for a first set of N data lanes. The FEC coded sequence includes FEC data blocks, in which each FEC data block has a plurality of data symbols. Alignment markers are added to the FEC coded sequence and the FEC coded sequence is multiplexed to produce a multiplexed sequence formatted for a second set of M data lanes. The multiplexing is performed only at boundaries between the data symbols or the alignment markers. The multiplexed sequence is transmitted on M data lanes.

Abstract: Presently disclosed is an apparatus and method for returning control of bandwidth allocation and packet scheduling to the routing engine in a network communications device containing an ATM interface. Virtual circuit (VC) flow control is augmented by the addition of a second flow control feedback signal from each virtual path (VP). VP flow control is used to suspend scheduling of all VCs on a given VP when traffic has accumulated on enough VCs to keep the VP busy. A new packet segmenter is employed to segment traffic while preserving the first in, first out (FIFO) order in which packet traffic was received. Embodiments of the invention may be implemented using a two-level (per-VC and per-VP) scheduling hierarchy or may use as many levels of flow control feedback-derived scheduling as may be necessitated by multilevel scheduling hierarchies.

Abstract translation: 现在公开的是一种用于在包含ATM接口的网络通信设备中将带宽分配和分组调度的控制返回到路由引擎的装置和方法。 通过从每个虚拟路径（VP）添加第二流量控制反馈信号来增加虚拟电路（VC）流量控制。 当流量累积在足够的VC上以保持VP忙时，VP流控制用于暂停给定VP上所有VC的调度。 采用新的分组分段器来分段业务，同时保持接收到分组业务的先入先出（FIFO）顺序。 可以使用两级（每VC和每VP）调度层次来实现本发明的实施例，或者可以使用多级调度层次可能需要的流控制反馈导出调度级别。

Abstract: A port adapter for connecting zero or more network interfaces to a host system having a SPI-4 bus is disclosed. The port adapter comprises zero or more network interfaces; a SPI-4 bus coupled to a host system to provide a communication channel between the host and the network interfaces; a control bus coupled to the host system for controlling and monitoring the port adapter; and interface logic that interfaces the SPI-4 bus and the control bus to the network interfaces. Methods are provided for selecting and using one of a small plurality of different packet formats for various networking technologies, so that the port adapter can hide details of the technology that it handles from the host system, and for operating the host system's SPI-4 bus at one of several speeds based on bandwidth requirements of the port adapter.

Abstract: In one embodiment, protocol violations of a particular protocol are induced at one or more predetermined intervals within a particular stream of information encoded according to the particular protocol in order to produce a marked particular stream of information for use in subsequent identification of the marked particular stream of information. The marked stream is multiplexed or otherwise communicated to a second device. The second device detects, and typically corrects, the induced protocol violations. And based on which stream of information included the induced protocol violations and the multiplexing/distribution pattern of the other streams of information, the second device can identify which stream is which and process or forward accordingly.
