Abstract: In an example of this disclosure, a method may include receiving, by a bit error location analyzer, a split information signal at a second data rate derived from an information signal at a first data rate. In this example, the second data rate is less than the first data rate, and the bit error location analyzer may be incapable of performing error analysis at the first data rate The method may include performing error analysis, by the bit error location analyzer, on information represented by the split information signal. In some examples, performing error analysis may include comparing the information represented by the split information signal to an information seed to determine a plurality of bit error locations in the information represented by the split information signal relative to the information seed.

Abstract: Techniques are described for determining pre-compensation parameters to compensate for signal integrity degradation along a signal path. A processor generates a first digital signal and receives a second digital signal. The second digital signal is generated from an optical-to-electrical conversion of a feedback optical signal that is generated from an electrical-to-optical conversion of an electrical signal by an optical module. The processor determines the pre-compensation parameters based on the first and second digital signals.

Abstract: In general, the invention is directed to techniques for reducing deadlocks that may arise when performing fabric replication. For example, as described herein, a network device includes packet replicators that each comprises a plurality of resource partitions. A replication data structure for a packet received by the network device includes packet replicator nodes that are arranged hierarchically to occupy one or more levels of the replication data structure. Each of the resource partitions in each of the plurality of packet replicators is associated with a different level of the replication data structure. The packet replicators replicate the packet according to the replication data structure, and each of the packet replicators handles the packet using the one of the resource partitions of the packet replicator that is associated with the level of the replication data structure occupied by the node that corresponds to that particular packet replicator.

Abstract: An arbiter system may include a first arbiter, a second arbiter, and selection logic. The first arbiter may be configured to select a first data identifier from among a group of data identifiers that are associated with a first bandwidth. The second arbiter may be configured to select a second data identifier from among another group of data identifiers that are associated with a second bandwidth. The selection logic may be configured to periodically select the first data identifier and the second data identifier so that the first data identifier and the second data identifier are respectively selected in proportion to the first bandwidth and the second bandwidth.
