+ CDN is another way to build a small station. The rental cost of space investment in the flow, directly effective. But electricity and stability are not optimistic. In fact, CDN is not just doing web services, such as in Korea, most of the CND traffic is occupied by online games. Just imagine, if you can spread the CDN node in a wide range, it is necessary to have a game so many areas, occupy so many servers? The conclusion is that while the actual access to the connection and response spe

Speaking of STM32 's Flsah, our first reaction is to install the program, in fact, STM32 on-chip flash not only used to install the program, but also to install chip configuration, chip ID, bootstrap program and so on. Of course, flash can also be used to load data. Collected some of their own information, the information is summarized, do not want to see can be directly transferred to the back to see how to operate on it. Flash category According to the use, the flash in the STM32 slice is divi

This article describes how to configure dual-address dual-Egress and how to apply NAT configurations. I believe this article will help you. Environment Description: uses the Cisco2621XM + NE-1E module, which has two FastEthernet and one Ethernet port. Now we use Ethernet port 1/0 to connect to the internal LAN, simulating a policy route based on the original address when there are 100.100.23.0 255.255.255.0.0 and 100.24.0 255.255.255.0.0 clients internally. Fastethernet 0/0 simulates the first

. The best example here is the 128 k isdn, which uses two 56 K channels at the same time to achieve a speed of K. When the ISP provides such a service, two independent lines are configured to connect to the same IP address. 　　 You can see that, although there are EQL modules in Linux that allow you to use two data cards on the computer at the same time, unless the ISP provides the same IP address for the tw

software. Error 611 The route is not available/612 The route is not allocated Problem: the dial-up network connection route is incorrect. Cause: the RasPPPoE is not fully and correctly installed, and the ISP Server is faulty. Solution: uninstall and reinstall any PPPoE software, and call the ISP to ask Error 617 The port or device is already disconnecting Problem: the device connected to the dial-up networ

supports three common Internet access methods. You can select and set the required parameters based on your needs. 1) Dynamic IP Address: the IP address is automatically obtained from the ISP. Users accessing the Internet in this way do not need any additional settings. However, some ISPs may need to bind the MAC address, so you need to set the MAC clone in the vro. MAC clone: Clone the MAC address. If you need this function, select enable. MAC addre

I. Overview: In actual work, it is estimated that two ISP lines, such as China Telecom and China Netcom, are often connected using ASA, and there is not enough budget to buy load balancing equipment, however, we want to achieve load sharing and automatic switching of links. We want to return traffic from China Telecom, from China Telecom to China Telecom, and from China Netcom to China Telecom. When one of the lines fails, all traffic never goes throu

which is the simple analysis that distributes content around the world and provides content to clients from the nearest location, which significantly reduces the time it takes to propagate packets.We may not be able to get the packets to propagate faster, but we can put the content in a strategic way to reduce the distance from the user closer! With CDN, we can deliver significant performance gains for data dissemination.The "last mile" delayIronic?? Is that the reality is often not across the

Prime factor for depositing all numbersIf two numbers are not coprime, then there must be a prime factor between them.Dp[i][0] Indicates the maximum number of the number of first I can be obtained in the sequenceDP[I][1] indicates that the number of the first I was selectedDp[i][0] = max (dp[i-1][0], dp[i-1][1])DP[I][1] = max (dp[pos][1] + 1, dp[i][1]);The last position where the prime number factor of the POS bit I is the first occurrence#include #include #include #include using namespace Std;c

Blog 1: I. Network Settings This is because you need to manually specify the IP address, gateway, and DNS server connection mode, and use the proxy server to access the Internet. Carefully check the computer's network settings.Ii. DNS server problemsWhen ie cannot browse the Web page, try the IP address first. If yes, it should be a DNS problem, the DNS problem may be caused by an error in obtaining the DNS when the network is connected or a problem with the DNS server itself. In this case, you

Error 611 The route is not available ERRDR 612 The route are not allocated Problem: The dial-up networking connection is not routed correctly. Reason: Raspppoe not fully and correctly installed, ISP server failure. Solution: Uninstall any PPPoE software, reinstall it, and call the

that the order of the subnet masks here is the opposite of what is normally written, i.e. 0.255.255.255. The fifth step is to set up the multiplex dynamic address conversion. In global setting mode, set up a multiplex dynamic address conversion between the internal local address and the internal legal IP address 。 The command syntax is as follows: IP NAT inside source list access list number pool internal legal address pooling name overload Example: IP nat inside source List1 Pool Onlyone overl
