What is the structure of VRP?
VRP is built on element structure, consisting of general control plane(GCP), service control plane(SCP), data forwarding plane(DFP),system management plane (SMP ), system service plane(SSP).
1. GCP: it supports network protocol, particularly TCP/IP, including IPV4 and IPV6, and it will support IPX, etc.
2. SCP: it supports GCP and value-added services, including connection management, user authentication and accounting, user policy management, VPN, multicast service management and FIB related to maintenance and control.
3. DFP: it provides forwarding for the system, consisting of forwarding engine and FIB.
4: SMP: it functions to manage the system, connecting to the interface of device, and processing the external control input and protocol configuration.
5. SSP: it supports public system service, including memory management, timer, IPC, loading, transformation, task/process management and element management.
