ZXR10 5900 5200 Product Description
subsystem provides support for the running of the hardware, allocating resources for the
hardware, and provides hardware-related interfaces for the upper-layer software. The
operation support subsystem relies on the RoS platform of the ZXR10, and it is
composed of system support, system control, software version control, BSP, and SSP. It
can be further divided into operating system kernel, process scheduling, process
communication, timer management, and memory management modules. The functional
block diagram for the operation support subsystem is shown in the following figure

4.3.1.2 MUX Subsystem
The MUX subsystem exchanges information between the hardware driver and the
upper-layer software, and performs measurement and monitoring on the software table
of the switch chipset(s). The MUX subsystem mainly performs data distribution and
measurement and monitoring. After the MUX layer receives data from hardware driver
module, it performs forwarding by type according to the ETHER TYPES fields in the
MAC frames. The data distribution of the MUX also performs encapsulation for the data
sending to the hardware driver, providing the upper layer software modules with a data
sending function for invocation. When the modules on the upper layer have data packets
or protocol packets to send, they can invoke the data sending function provided by the
MUX. The measurement and monitoring function measures the status of hardware driver
layer, physical layer and MUX layer, measures packets received/sent, monitors access
to the register, performs sniff operations to the data packets, and provides OAM module
with interface function.
