The transition to multicore processing requires changing the software programming model, scheduling, partitioning, and optimization strategies. Software often requires modifications to divide the workload among cores and accelerators, to use all available processing in the system and maximize performance. Here's how you and your team can make the switch.

 

Networking systems, for example, normally include control-plane and data-plane software (shown in Figure 1). The control plane is responsible for managing and maintaining protocols (such as OSPF, SNMP, IPSec/IKE) and other special functions such as high-availability processing, hot plug and play, hot swap, and status backup. Control-plane functions include management, configuration, protocol hand-shaking, security, and exceptions. These functions are reliability sensitive but not extremely time sensitive. Normally, control-plane data packets/frames only occupy ~5% of the overall system load.
