Routing Engine
The Routing Engine consists of JUNOS software running on an Intel-based Peripheral Component Interconnect (PCI) platform. The JUNOS kernel supports JUNOS system processes which handle system management processes, routing protocols, and control functions (see Figure 22).
The Routing Engine handles all the routing protocol processes, as well as other software processes that control the router interfaces, the chassis components, system management, and user access to the router. These routing and software processes run on top of a kernel that interacts with the Packet Forwarding Engine.
The Routing Engine has a dedicated 100-Mbps internal connection to the Packet Forwarding Engine.
