摘要： A stacked switch includes two or more individual network switches connected to each other in a ring or daisy chain topology over stacking links, and at least one port on two or more of the individual switches comprising the stacked switch is a member of a LAG configured on the stacked switch. Each of the individual switches comprising the stacked switch include control plane and data plane functionality that operates to maintain switching tables and to process network data ingressing to the switch to determine how to forward the network data through the switch to an egress point. The control functionality included in each of the switches comprising the stacked switch also includes an enhanced ECMP functionality that operates to optimize the use of stacking link bandwidth on the stacking links connecting the two or more individual switches to each other.

摘要： A high-speed router backplane is disclosed. The router backplane uses differential signal pairs on multiple signal layers, each sandwiched between a pair of digital ground layers. Thru-holes are used to connect the differential signal pairs to external components. To reduce routing complexity, at least some of the differential signal pairs route through a via pair, somewhere along their path, to a different signal layer. At least some of the thru-holes and vias are drilled to reduce an electrically conductive stub length portion of the hole. The drilled portion of a hole includes a transition from a first profile to a second profile to reduce radio frequency reflections from the end of the drilled hole.

摘要： A physical layer device distributes a high-speed packet data stream to multiple lower-speed physical channels, and reverses the process to receive a high-speed packet data stream that has been distributed across multiple lower-speed physical channels. The packet data is distributed by removing interpacket gap characters from between packets and using a different control character to delineate packets. Interpacket gap characters can then be used to delineate equal-length frames distributed to each of the multiple physical channels. Each frame consists of a concatenation of fixed-size blocks of packet data. By selecting a frame size larger than the average packet size, overhead on the multiple physical channels can actually be lower than the overhead on the single high-speed channel, allowing the aggregation to achieve line rate operation at the high-speed rate.

摘要： Methods of designing a backplane, a backplane, and a packet switch using such a backplane are disclosed. The backplane comprises communication channels that connect each of a set of first card slots to each of a set of second card slots. Instead of forcing the backplane to route the communication channels to match a preset card configuration, the backplane communication channels are routed so as to reduce crosstalk and attenuation on at least the most difficult routing pairs. The cards perform logical translation of their backplane traffic to conform to the physical pin assignment for the particular card slot in which they are inserted. Other embodiments are also described and claimed.

摘要： In one embodiment, a hybrid backplane coding scheme transmits data using lengthy sequences of scrambled data, separated by 8b/10b control character sequences that prepare the receiver for the next scrambled sequence and permit realignment if necessary. Advantageously, the sender of the scrambled data can be changed during the control character sequence. The hybrid backplane coding scheme can be designed such that the power spectral density of scrambled data and control character sequences are similar, which permits good performance with high-speed electrical differential receivers. Other embodiments are described and claimed.
