A network device includes a plurality of blades, each having a plurality of CPU cores that process requests received by the network device. Each blade further includes an accumulator circuit. Each accumulator circuit periodically aggregates the local counter values of the CPU cores of the corresponding blade. One accumulator circuit is designated as a master, and the other accumulator circuit(s) are designated as slave(s). The slave accumulator circuits transmit their aggregated local counter values to the master accumulator circuit. The master accumulator circuit aggregates the sets of aggregated local counter values to create a set of global counter values. The master accumulator circuit transmits the global counter values to a management processor (for display), to the CPU cores located on its corresponding blade, and to each of the slave accumulator circuits. Each slave accumulator circuit then transmits the global counter values to the CPU cores located on its corresponding blade.

Load balance connections per server in multi-core/multi-blade system

A multi-processor architecture for a network device that includes a plurality of barrel cards, each including: a plurality of processors, a PCIe switch coupled to each of the plurality of processors, and packet processing logic coupled to the PCIe switch. The PCIe switch on each barrel card provides high speed flexible data paths for the transmission of incoming/outgoing packets to/from the processors on the barrel card. An external PCIe switch is commonly coupled to the PCIe switches on the barrel cards, as well as to a management processor, thereby providing high speed connections between processors on separate barrel cards, and between the management processor and the processors on the barrel cards.
