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

for dial-up networking connections is not determined. Reason: Raspppoe is not fully and correctly installed. Solution: Uninstall any PPPoE software and reinstall it. 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

Let the computer automatically remember the mailbox password Each time you receive or send a message, the software will ask you to enter your own mailbox password, and the password sent to your Internet company for check, if the password is not correct, you can not operate the message. Under normal circumstances, the password input, transmission and reconciliation about 30 seconds. If the software to remember the password, each time the mail operation, it will automatically transfer and check,

Routers in the use of the process, you will encounter a variety of fault situations, how should this be done? In fact, there are many articles about router failure in this site, but there are many people do not know what kind of failure, this article to illustrate some of the symptoms and reasons. One, ADSL modem on the general will have an ADSL lamp, under normal circumstances, the modem power and after the telephone line, the lantern is roughly regular speed flashing, flashing finally stop in

For the general user, is not very understanding of the router settings, so I studied the router set up the specific operation, here to take out and share with you, hope for everyone useful. Maybe someone will ask: What is a route? Well, let me ask you, if you have more than two PCs, how would you make them surf the internet at the same time? "Let a proxy server" OK, then this agent service can not shut down, can not crash, otherwise it will incriminate others. And some

1024*768*256, is 640*480*256, how can be set to 800*600*65536? If/etc/x11/xf86config (Redhat) or/etc/xf86config (Slackware) is set correctly, you should be able to change the resolution dynamically using the 29, the Linux allocated number to connect the ISP method? If you use Redhat 6.0, you can completely resolve it using the Redhat method: 1 enter x windows, open control Pannel 2 Select the network configuration, in the network interface there are

How does the Web work? How do you make your own web site? What is a Web site host? What is an Internet service provider (ISP)? What is the world Wide Web? WWW is a computer network all over the world. All computers in the WEB can communicate with each other. All computers use a communication standard called HTTP. How does WWW work? Web information is stored in a document called a Web page. A Web page is a file that is stored on a computer called a

occupy the bandwidth. These solutions can effectively improve the transmission quality. RIP, OSPF, and BGP protocols On the internet now a large number of running routing protocols have RIP (Routing information protocol-Routing Information Protocol), OSPF (Open shortest Path first--Open shortest circuit priority) and BGP (Border Gateway protocol-Boundary Gateway Protocol). RIP, OSPF is an internal gateway protocol, applicable to the operation of a single ISP's unified routing protocol, a netw

bandwidth can improve efficiency, from the network level and the transaction object of comprehensive consideration, can basically be divided into three categories? bandwidth operations between long-distance backbone operators and local operators, bandwidth operations between local operators and users, bandwidth operations for business-to-business companies that specialize in bandwidth transactions. Backbone bandwidth operations are mainly in three ways: wavelength for intercontinental intercon

Some recommendations for preventing distributed denial of service (DDoS) attacks on Cisco routers 1, the use of IP verfy unicast reverse-path network interface command This feature examines each router's packet. In all routing items that the packet reaches the network interface of the router's CEF (Cisco Express forwarding) table, the router discards the packet if there is no route for the packet source IP address. For example, a router receives a packet with a source IP address of 1.2.3.4, an

With the development of the Internet in China, the connection between ISP service providers and Internet is also changing. On a network connection, from a single connection to the Internet via multiple telecommunications companies, in terms of routing protocols used, from the use of static routing protocols to the use of BGP (Border Gateway Protocol). How does the ISP deploy the BGP routing protocol rationa

displayed. Do you think it is a bit like the configuration interface of ADSL cat? We just need to set it as usual. For most users connected to PPPoE, you only need to enter the user code and password and click "Connect" to connect to the Internet. If the network cannot be connected, enter debug in "other connection Parameters" and click "Connect" to display more detailed connection information. Click "Save to vro floppy disk" to save the settings on the current screen to the vro boot floppy dis

After inspection, it was found that the out-of-the-box BIOS was interrupted on the 15th that should have been reserved for the hard disk controller and allocated to the data card. Finally, the author gave up using plug-and-play products on the old computer, because it is not worth the time. Therefore, before purchasing a data card, you must first check whether there are any changes from COM1 to COM4. On the author's bulletin board http://trevormarshall.com/BYTE/), I s

network, computers communicate through internal IP addresses. When the internal computer needs to communicate with the external internet, the device with the NAT Function (such as a router) converts an internal IP address to a valid IP address (that is, the requested IP address) for communication.2. Why Nat?Let's see under what circumstances we need to perform Nat.Assume that an ISP provides Internet access services in the campus. To facilitate manag
