## Abstract

In one embodiment, a system includes a number of application-specific integrated circuits (ASICs). At least one of the ASICs is configured to process incoming data packets and outgoing data packets. At least one of the ASICs is configured to move data between a respective networking module and a destination networking module. The system also includes a cable backplane having a number of parallel cables configured to transmit data between the number of ASICs.
