Abstract: Various techniques can be used to avoid loops during network convergence after a topology change such as a failure. For example, a method can involve detecting a failure that disrupts an existing forwarding path between a node and a destination node; calculating at least one updated forwarding path from the node to the destination node; identifying a maximum time for at least a portion of the network to reach a post-convergence state with respect to the failure; until the maximum time has elapsed at the node, explicitly specifying at least a portion of the updated forwarding path in packet headers of any packets being sent from the node to the destination node; and after the maximum time has elapsed at the node, non-explicitly specifying the portion of the updated forwarding path in packet headers of any additional packets being sent from the node to the destination node.

Abstract: A processor has a processing pipeline with first, second and third stages. An instruction at the first stage takes fewer cycles to reach the second stage then the third stage. The second and third stages each have a duplicated processing resource. For a pending instruction which requires the duplicated resource and can be processed using the duplicated resource at either of the second and third stages, the first stage determines whether a required operand would be available when the pending instruction would reach the second stage. If the operand would be available, then the pending instruction is processed using the duplicated resource at the second stage, while if the operand would not be available in time then the instruction is processed using the duplicated resource in the third pipeline stage. This technique helps to reduce delays caused by data dependency hazards.

Abstract: A data processing apparatus has a pipeline for performing a processing operation involving a conditional step which is required only if at least one input operand satisfies a predetermined condition. Control circuitry detects whether the condition is satisfied. If not, then the pipeline is controlled to perform the operation bypassing the conditional step to generate the output operand a first number of cycles later than a start cycle in which the operation starts, and the output operand is forwarded over a forwarding path. If the condition is satisfied, then the pipeline performs the operation including the conditional step to generate the output operand a second number of cycles later than the start cycle, where the second number is greater than the first number. The output operand is written to a destination register the same number of cycles later than the start cycle regardless of whether the condition is satisfied.
