DPCs provide multiple physical interfaces and Packet Forwarding Engines on a single board that installs in a slot in the Juniper Networks MX-series Ethernet Services Router. A DPC receives incoming packets from the network and sends outgoing packets to the network. The Packet Forwarding Engines on a DPC are equipped with purpose-built application-specific integrated circuits (ASICs) that perform packet processing and forwarding. Each Packet Forwarding Engine consists of one I-chip for Layer 3 processing and one Layer 2 network processor. To ensure that the MX-series delivers the lowest cost per port without sacrificing performance, reliability, scalability, or functionality, each Ethernet services router has been purpose-built for optimization to provide both switching and carrier-class Ethernet routing functions. The MX-series Ethernet Services Routers have three models of Dense Port Concentrators: DPCE-X, DPCE-R, and DPCE-Q.
