The core layer switch is mainly used for route selection and high-speed forwarding, providing an optimized and reliable backbone transmission structure, so the core layer switch application has higher reliability and throughput. The aggregation layer switch is the conver...

First of all, we need to clarify a concept: access layer switches, aggregation layer switches, and core layer switches are not the classification and attributes of switches, but are divided by the tasks they perform. They have no fixed requirements, and mainly depend on ...

Server-side fiber network card due to advanced technology, the price will be much more expensive, therefore, we must pay attention to the use of the environment when choosing, in order to reduce the CPU occupation rate, the server should choose a processor with automatic...

The HBA (Host Bus adapter) is a circuit board and/or integrated circuit adapter that provides input/output (I/O) processing and physical connectivity between servers and storage devices. Because HBA relieves the burden of the main processor in data storage and retrieval ...

A collection of access connections supported by an optical transmission system that are shared across the same network side interface. The optical access network may contain a number of optical distribution networks (ODN) and optical network units (ONU) connected to the ...

Optical transmission is the technology of transmitting in the form of optical signals between a sender and a receiver. Optical transmission equipment is to convert a variety of signals into optical signals in the optical fiber transmission equipment, so modern optical tr...
