A router-on-a-chip, often abbreviated as RoC, refers to a system-on-a-chip (SoC) or a dedicated integrated circuit designed to perform the primary functions of a network router. Instead of a traditional router that uses a separate central processing unit (CPU), memory, and specialized network interface cards (NICs) housed in a chassis, a RoC integrates these components onto a single silicon die. This consolidation allows for significant reductions in size, power consumption, and cost.

The core of a router-on-a-chip typically includes processing units, memory controllers, network interfaces (such as Ethernet ports), and specialized hardware accelerators for packet processing, routing table lookups, and Quality of Service (QoS) management. These accelerators are crucial for achieving high throughput and low latency, essential for modern network devices.

RoCs are employed in a wide range of networking equipment, from small home routers and consumer-grade network devices to enterprise-level equipment and telecommunications infrastructure. Their compact nature makes them ideal for embedded systems and devices where space and power are at a premium. The integration also simplifies the design and manufacturing process for network equipment vendors. By consolidating functionality, RoCs contribute to the ongoing trend of miniaturization and increased efficiency in networking technology.
