Abstract:For the PC104 SCM/deth dual-port ethernet card, an intelligent dual-redundancy Network Driver Based on the Vxworks system is designed, the driver provides functions such as network communication fault diagnosis and intelligent switching between NICs. By testing the performance of the smart dual-redundancy driv
This article mainly introduces the problems encountered in the selection of Dual-WAN port broadband routers, and gives a specific introduction to IP balancing. I believe this article can help you.
Simply put, the dual-WAN router has two physical WAN ports for Internet access, while the common Broadband Router only has one Wan
I believe many small and medium-sized enterprises are using dual-WAN broadband routers. Here we will introduce a high-quality and cheap dual-WAN port Broadband Router, which has been around for many years, various manufacturers have launched products with different functions and strong performance. There are more products, and there is a trend of getting charming
With the development of China's routing industry, dual-WAN Port Routers are also widely used. Here we mainly introduce a cost-effective dual-WAN port router. Currently, many Internet cafes use dual-WAN Port Routers. The
Debug windbg dual-host Kernel through the parallel port, windbgkernel
Preface:
Windows kernel mode debug is available in two ways:
1. windbg dual-host kernel debugging
2. traceview capture wpp log debugging
This section describes how to use the parallel port for windbg dual
This is a dual-WAN port router evaluation. I have made a detailed introduction to what you are concerned about, from the appearance design of the interface to various internal performance indicators, they all make us feel bright. In our report, we can also learn its settings.

the switchover will be repeated back and forth, resulting in network anomalies. The Cisco switch is designed to prevent switch loops from opening port protection by default, which results in a long port start-up time, typically around 10S, and does not require a dual-machine switchover. In switch port mode, the busine
With the development of the routing industry, more and more new technologies are emerging. Multi-WAN Port Routers are also one of them. How can we use dual-WAN Port Routers to achieve communication between China Telecom and Netcom? The following is a detailed analysis. Currently, China's ISP service providers mainly include China Telecom and China Netcom. The ban
Communication between the bound dual-network port device: Packet recognition-Linux general technology-Linux programming and kernel information. For details, see the following. An embedded device with two network ports on it. I bound them to one for use and communicated with the server for multicast. The multicast address is 227. 0. 0. 1.
When both network ports are connected, the server sends multicast dat
Ip time dual-WAN port router is a new product in the domestic market, but it is a promising router. Not only is the appearance good, but the performance is also the best among similar products, the following tests can show its strength.

the expected results. Under the same conditions (temperature, voltage, and other external factors are ignored) the time spent on sending and receiving is shown in table 2.
Taking the transmission of 4 KB data as an example, table 2 shows that sending and receiving saves 0.547 076 S and 0.042 832 s respectively when using FIFO. Assume that the 1-bit data is transmitted in θ s and the data volume is n. In this case, we can see that the time difference between the use of FIFO and the use of FIFO

QVM100 is a product launched by Qno xiaonuo, a professional broadband access device brand for small and medium-sized enterprises. The specifications, functions and features of the software and hardware products are designed for ordinary small and medium-sized enterprises.
Although QNO QVM100 dual-WAN Port Routers are not small and medium-si
TL-LINK series products because of low price and stable quality, solid by the majority of users kiss, its "+" series router provides a dual WAN port design, but for how to use such a device, users have many questions. We take R480T + as an example to describe in detail the WAN port settings, online WAN port detection,

My company's products are dual network port, the original program is the TCP/IP protocol stack, because it is simple to implement the ARP and TCP, UDP the simplest case, so sometimes on the public network will encounter problems.
Later in the single-network port of the product transplant LWIP, lightweight TCP/IP protocol stack, to a certain extent solved th
