Abstract: Software tables in the control plane of a network device are downloaded into the data plane hardware after a reboot of the control plane. Valid entries are identified and downloaded while reducing the downloading invalid or otherwise unused entries to improve download times and reduce disruption of traffic resulting from the download. In some instances, blocks of entries containing a high ratio of valid to invalid entries are identified and downloaded to the hardware. In some instances, entries in the software tables that differ from corresponding entries in the hardware (diff entries) are identified and downloaded. In some instances, chunks containing diff entries and non-diff entries are identified and downloaded.

Abstract: In general, embodiments relate to a method, for managing a network device, that includes accessing, by a feature agent of the network device, an allocation data structure, wherein the allocation data structure specifies a first portion of memory and a second portion of memory, identifying, using the allocation data structure, the first portion of the memory to be used during an upgrade, wherein the second portion of memory is used for storing a network device table, wherein the network device table is used by a packet transmission component while the upgrade is being performed, and upon completion of the upgrade, updating the allocation data structure to specify that the packet transmission component use a second network device table and stop using the network device table, wherein the second network device table is initially populated during the upgrade.
