摘要： The invention provides a method and system for accessing ports of a very high-speed, fixed-size cell switch fabric. It is aimed at permitting a tradeoff between the overall number of I/Os required to access all the switch ports, that must stay within the board and modules packaging constraints and the maximum speed at which each individual wire, making up ports, may be toggled while not violating any of the speed limitation imposed by the transmission medium (board wiring) or the module interface devices; i.e., receivers and drivers. This is achieved by eliminating the need of having extra control signals, thus, greatly easing the requirement for module and board I/Os. Then, synchronization is obtained from in-band information transported by fixed-size idle logical units from a robust protocol based on two CRCs. The acquisition of synchronization does not require any particular training sequence and is conducted by the receiving device component only which retrieves computed delimiters on which it locks. The method does not assume any overhead and is obtained from the extra bandwidth available while no minimum is ever required after synchronization has been acquired.
摘要翻译：本发明提供一种用于访问非常高速，固定大小小区交换结构的端口的方法和系统。它旨在允许访问所有交换机端口所需的I / O总数之间的权衡，这些权限必须停留在电路板和模块封装约束之内，并且组成端口的每个单独电线的最大速度可能会被切换同时不违反传输介质（电路板接线）或模块接口设备施加的速度限制; 即接收器和驱动器。这是通过消除对额外的控制信号的需要而实现的，从而大大减轻了模块和板I / O的需求。然后，从基于两个CRC的稳健协议的固定大小的空闲逻辑单元传送的带内信息中获得同步。获取同步不需要任何特定的训练序列，仅由接收设备组件执行，检索其锁定的计算分隔符。该方法不承担任何开销，并且可以从可用的额外带宽获得，而在获取同步之后不需要最小值。

摘要： A fault tolerant switching architecture is provided with two separate switch fabrics each having a switch cure located in a centralized building and a set of SCAL elements distributed in different physical areas. Each SCAL element has both a SCAL receive element and a SCAL transmit element for access to a corresponding input and output port of the swatch core. A set of port adapters is distributed at different physical areas, with each connected switch fabrics via a particular SCAL element so that each switch core receives the sequence of cells coming from any port adapter and conversely any port adapter may receive cells from either one of the switch cores. Each switch fabric can detect an internal breakdown condition occurring in one of its element and send an error control signal to the peer element located in the other switch fabric. Each switch core extracts the Switch Routing Header (SRH) from the cells entering the switch core, and a routing table for obtaining a bit map value that indicates the output ports to which the cell should be routed. An additional controllable masking mechanism is used for altering the value of the bit map in response to the detection of the error control signal from the peer switch core. The routing process is then performed with the altered value of the bitmap.

摘要： Method and apparatus for recognizing of a framing pattern of M single bits distributed at intervals of a fixed number, N of bits, as measured from the start of one framing bit to the start of the next, in an incoming serial bit stream. The system makes a computation following each reception of an arbitrary group of N incoming data, and after the minimum number of computation steps to distinguish between a `look-alike` framing pattern and a `true` framing pattern, points out with no ambiguity the very position of the "true" pattern within the bit stream, thus allowing synchronization over that stream.
