The maximum rate of Ethernet switch stack is faster, Which is multiple times faster than the port rate of the switch. Not all switches support Ethernet switch stack, when the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways to connect a vswitch: Ethernet switch stack and cascade.

From the data, we can see that the bandwidth of the Ethernet switch stack is dozens of times the speed of the switch port, which can effectively improve the network performance, when the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways to connect a vswitch: Ethernet switch stack

There is a binary file of about MB, which stores multiple JPG images. The file format is as follows: Unrelated data ZoneJpg image data ZoneUnrelated data ZoneJpg image data ZoneUnrelated data ZoneJpg image data Zone...... The starting mark of the jpg image is "FF D8 FF E0 00 10 4A", and the ending mark is "FF D9 ". What should I do if I want to read the jpg image data from this file and generate separate image files? I helped you write a program and tested a file containing only one picture.Int

This paper is a DSP and FPGA communication test based on chuanglong TL665xF-EasyEVM Development Board. The brief introduction of the TL665xF-EasyEV Development Board is as follows: consists of the core board + the bottom board. The core board DSP end adopts single-core tms320c6655 or dual-core tms320c6657 processor, FPGA end adopts Xilinx Artix-7 processor to realize heterogeneous multi-core processor architecture, DSP and FPGA internal through UPP, emif16, SRIo connection; The baseboard interfa

The Fiber jumper (also known as the optical fiber connector), which is the optical connector to access the optical module, also has many kinds, and can not be mutually used. The SFP module is connected to the LC fibre optic connector, while the GBIC is connected to the SC fiber optic connector. The following is a detailed description of several commonly used optical fiber connectors in Network engineering: ①FC Type fiber jumper: The external streng
