摘要： Embodiments of methods, apparatuses and systems for balancing flow across trunk groups are disclosed. For example, a method of routing a flow of frames may include applying a correspondence between logical ports and physical ports of a switch. Other examples may include receiving at least one frame; selecting an exit port of a switch for the one frame to exit, based at least in part, on balancing flow across trunk groups; and transmitting the at least one frame.

摘要： Trunk groups being assigned logical port values, with multiple physical ports designated to form the given trunk group, thus corresponding to the logical port. This provides greater flexibility in developing trunk groups. Each trunk group delivers frames in order. Routing and balancing decisions are based on the logical port not the physical port.

摘要： Accordingly, there is disclosed herein an augmented Fibre Channel (FC) frame format which may provide support for multiple fabric FC networks, and may improve the performance of modularly-constructed switches. In one embodiment, the augmented FC frame format is modulated on a carrier signal and the frame includes: a start-of-frame field; a supplementary header field that follows the start-of-frame field; a frame header field that follows the supplementary header field; a cyclic redundancy code (CRC) checksum field; and an end-of-frame field that follows the CRC checksum field. The supplementary header field may include a destination tag that identifies a target fabric to which the frame is directed. Alternatively, or in addition, the supplementary header field may include an egress port identifier that identifies a switch port through which the frame is to exit a switch. The supplementary header may also include flags to request special handling by the receiver.

摘要： An inverse quantizer is provided with a reduced bit-width. In one embodiment, the inverse quantizer receives quantized DCT coefficients in sign+magnitude form with 1+11 bits of resolution, and produces reconstructed DCT coefficients with 1+11 bits of resolution. Although this is less than the theoretical minimum bit-width required to represent the entire reconstructed DCT coefficient range [−2048, 2047] mandated by the MPEG standard, certain IDCT implementations will maintain IEEE compliance when the −2048 value is replaced with −2047. (An example of one such implementation is provided in a co-pending application.) This reduces the range to [−2047, 2047]. In one embodiment, the inverse quantizer includes a dead-zone expander, a quantization multiplier, a mismatch controller, and a bit-width reducer. The dead-zone expander receives quantized coefficients with 1+11 bits of resolution, doubles them, and then increases their magnitude by one. The quantization multiplier multiplies the result by a 15 bit quantization matrix scale factor to produce reconstructed DCT coefficients. The mismatch controller modifies least significant bits of DCT coefficients according to the MPEG standard and limits the range of values for the DCT coefficients. Finally, the bit-width reducer converts the DCT coefficient representation to 1+11 bits.
摘要翻译：逆量化器具有减小的位宽。在一个实施例中，逆量化器以1 + 11位分辨率接收符号+幅度形式的量化DCT系数，并产生具有1 + 11位分辨率的重构DCT系数。尽管这不到表示由MPEG标准规定的整个重构DCT系数范围[-2048,2047]所需的理论最小位宽，但是当-2048值被-2047替换时，某些IDCT实现将维持IEEE的合规性。（一个这样的实现的示例在共同未决的应用中提供。）这将范围减小到[-2047,2047]。在一个实施例中，逆量化器包括死区扩展器，量化乘法器，失配控制器和位宽减小器。死区扩展器接收1 + 11位分辨率的量化系数，使其倍增，然后将其幅度增加1。量化乘法器将结果乘以15位量化矩阵比例因子以产生重构的DCT系数。不匹配控制器根据MPEG标准修改DCT系数的最低有效位并限制DCT系数的值的范围。最后，位宽减速器将DCT系数表示转换为1 + 11位。

摘要： Autodetermination circuitry examines packets transmitted internally to an egress port of a switching device in order to learn the associated flow. The autodetermination circuitry maintains a flow memory recording the highest traffic volume flows and unlearns the flows exhibiting lower traffic volumes to make room for other higher traffic volume flows. Accordingly, as some flows decrease in traffic volume and other flows increase in traffic volume, the flows decreasing below a threshold are dropped from a flow memory, and other flows increasing in volume above the threshold are added to the flow memory. In this manner, only the most likely offending flows are maintained in the flow memory. Accordingly, when congestion is detected, the switching device can identify one or more source devices contributing the most to the congestion and take steps to alleviate the congestion by decreasing the traffic volume originating from one or more of those sources.
摘要翻译：自动确定电路检查内部传输到交换设备的出口端口的数据包，以便了解相关流程。自动确定电路维护记录最高流量的流量存储器，并且显示出具有较低流量的流量，为其他较高流量的流量腾出空间。因此，由于业务量的一些流量减少，流量的其他流量增加，流量低于阈值的流量从流量存储器中下降，并且流量存储器中增加体积超过阈值的其他流量。以这种方式，在流量存储器中仅维持最可能的违规流。因此，当检测到拥塞时，交换设备可以识别对拥塞贡献最多的一个或多个源设备，并且通过减少源自这些源中的一个或多个的业务量来采取措施来减轻拥塞。
