In some implementations, a first processing component of a network device may receive first traffic data obtained by a second processing component of the network device. The first processing component may store the first traffic data as residual statistics. The first processing component may obtain second traffic data associated with a copy of a traffic stream processed by the first processing component based on storing the first traffic data as the residual statistics. The first processing component may perform a switchover from the second processing component to the first processing component. The first processing component may determine current traffic data based on the residual statistics and the second traffic data. The current traffic data may be determined based on performing the switchover from the second processing component to the first processing component.

Systems and methods for replicating traffic statistics on redundant packet forwarding engine system

In general techniques are described for allocating global identifiers to forwarding units of a network device. A network device having one or more hardware-based microprocessors and an allocation module executable by the microprocessors may implement the techniques. The allocation module may maintain a first map that indicates global identifiers that are allocable to a plurality of forwarding units of the network device, and a second map that indicates local identifiers that are allocated to one of the plurality of forwarding units. The local identifiers may be based at least in part on the global identifiers. The allocation module may allocate to the forwarding unit, a global identifier indicated by the first map that is not allocated to any one of the plurality of forwarding units by comparing the second map to one or more portions of the first map to identify the unallocated global identifier of the first map.
