Description

A903-RSP1A-55 Overview

Cisco A903-RSP1A-55 is the Cisco ASR 903 Route Switch Processor. Cisco ASR 900 Series RSP modules contain separate control plane and data plane components. These include the main control plane CPU for the Cisco IOS Software operating system and platform control software. The data-plane packet processing and traffic management is performed by the Carrier Ethernet application-specific integrated circuit (ASIC).
