The P4LR 1KHL015107R0001 Network interface module provides the following functions:
Status interface module: Used to intercept status information uploaded by other functional units in the computing system from the status layer, including data request information and functional unit release information.
For data request information, the status interface module caches it in the built-in functional unit request cache and can forward it through the configuration network when the configuration interface arbitrator module allows it.
The status interface module will parse the release information of the functional unit, and generate the corresponding release signal according to the result of the analysis to transmit to the corresponding idle functional unit queue.
Configure interface modules: Perform packet operations based on network protocols.
In addition, the network interface module also includes various types of interfaces, such as optical ports, electrical ports, and Combo ports. An optical port is an optical fiber interface used to transmit optical signals. Common optical ports are the interfaces of pluggable optical modules. Electrical port, also known as RJ45 port, used to plug twisted pair (network cable), processing electrical signals, the general rate of 10M, 100M, up to 1000M. The Combo interface is an optical/electronic multiplex interface. One Combo interface corresponds to one GE electrical interface and one GE optical interface on the panel. The electrical interface and optical interface cannot work simultaneously.
Categories:
Wired interface module: Connects to network devices through physical cables, such as twisted-pair cables and coaxial cables.
Wireless interface module: such as Bluetooth module, WIFI module, Zigbee module, etc., through wireless signals (such as electromagnetic waves, infrared, etc.) to communicate with network devices.
Second, function and effect
Data transmission: The basic function of the P4LR 1KHL015107R0001 network interface module is to realize the transmission of data between network devices and transmission media.
Protocol conversion: In the process of data transmission, the network interface module is also responsible for encapsulating and unencapsulating the data according to the network protocol to ensure that the data can be correctly transmitted in the network.
Signal conversion: For wired interface modules, it needs to convert electrical or optical signals into signals that can be recognized by network devices;
