possible power loss caused by long-term operation and the elimination of peripheral radiation and conducting electrical noise, whether the cable housing can withstand the target environment and the compatibility of the terminal connector.
Shielding and Materials
There are many available shielding methods based on the cost of the application and the target. Including standard braided shielding, wound shielding, aluminum/polyester film, metal foil, Fla
performance is required. A high-speed optical fiber cable network needs to properly select the appropriate testing instrument.
Laser and LED
The laser emitting power is very high, and the emitted light is very concentrated, while the light emitted by the LED is usually scattered and the power is low. Compared with LED
correlation. The third step, because there is no such problem on the first level switch and S5500 , all can be located in the first and two levels between the network cable, because the cable distance is longer, about 100m , and the field can not be replaced. Therefore consider can reduce the negotiation speed of the port to reduce the requirements of the networ
Symptom descriptionA certain Bureau adopts the MA5200 + 2403F networking mode. Due to the small amount of upstream optical resources, the 2403F cascade mode is adopted in the residential area, and the cascade mode adopts five category of twisted pair wires, you can use PPPOE to access the Internet. Some second-level switch users report that the Internet access speed

guardian to each aggregate object. All operations on this resource are handed over to this guardian, and a lock-free queue is used to quickly queue up and hand over to the guardian. Through reactive programming, we can also avoid the occupation of CPU threads for a resource operation for too long. As long as we finish the competition for resources, we can immediately dispatch another thread to do the rest. In this way, serial sequential operations and parallel operations can be perfectly combi
High-speed Internet access without the need for WiFi light
No Wi-Fi signal is required. You can access the Internet by clicking an LED lamp. The School of Computer Science and Technology of Fudan University sent a message that an international cutting-edge communication technology that uses the visible light transmiss
For a special network application environment such as Internet cafes, there are usually dozens to hundreds of nodes in Internet cafes, different Nodes are constantly browsing, chatting, downloading, video-on-demand, and online games at the same time.

This article uses the well-known Squid Proxy Software in combination with ramdisk technology and DNS Cache Server to build a high-speed proxy server on the FreeBSD system. The ram-based Directory Pool (sometimes called ramdisk) can significantly improve the performance of applications, especially for those with more severe I/O. Because all I/O operations in the ram-based Directory Pool are actually complete
