Product Architecture
1.4.1.1.3.3.1 SCU
The SCU is fixed on the S2700. Each S2700 has one SCU.
The SCU is responsible for packet switching and device management. It integrates multiple functional modules,
namely, the main control module, switching module, and interface module.
Main Control Module
The main control module implements the following functions:
Processing protocols
Functioning as an agent of the user to manage the system and monitor the system performance according to
instructions of the user, and report the running status of the device to the user
Monitoring and maintaining the interface module and switching module on the SCU.
Switching Module
The switching module, also called the switching fabric, is responsible for packet exchange, multicast replication,
QoS scheduling, and access control on the interface module of the SCU.
The switching module adopts high performance ASIC chips to implement line-speed forwarding and fast
switching of data with different priorities.
Interface Module
The interface module provides Ethernet interfaces for accessing Ethernet services.
