Note: This note is written from a programmatic point of view, which is what I think is helpful for programming, not from the perspective of a network expertise. The following illustration shows the different partitioning of the architecture of the computer: the OSI seven-layer protocol architecture, the architecture of TCP/IP, and the architecture of the five-tier protocol: The following figure illustrates the changes that the application process's data undergoes during the transfer of the var

It was exactly the same as Noip's, and I rewrote the code a bit more clearly.Ideas See http://blog.csdn.net/vmurder/article/details/38734663But I still have to say it again.First of all, we build the minimum tree, this is not proof, because in accordance with the Kruskal map, each traversed an edge, it is equivalent to some of the inquiry between the road, and must be the edge.And then it's YGYLCA. Thought: The thing to be disposed of to the node, in a certain order in the node processing, and a

PHP RSA Encrypted Transport code sample When it comes to transmission of sensitive data, it is best for both parties to use cryptographic decryption. RSA Asymmetric encryption is a promising one. The server can keep its private key and send it to the client's corresponding public key. So that we can decrypt each other. RSA encryption and decryption implementation in PHP: First, you generate a pair of public key private keys. The prerequisi

Baidu Map Public transport Plan query use: In the search box directly enter "from where to", or select a bus, and enter the start and end point in the input box; You can also initiate a query with a bubble or right mouse button. The text area on the right shows you the exact calculated bus plan, including the bus and subway. Up to 10 scenarios are displayed, and the click Scenario will expand and you can view a detailed description. There are three s

If the host has multiple network interfaces, the route can be used to specify the interface for replication. Specify by IP addressSet up different network ports, one for load balancing, and two for error switching.The following is an example of error switching, which can be used as the priority 2 interface of a backup when a pair of interfaces to the 1 fails:CREATE ACTIVE STANDBY PAIR dns1, d

site users upload pictures, attachments, avatars, etc., note that the site's program code should not be placed in the NFS share, because the website program is the development of operation and maintenance personnel unified release, there is no release delay issue , direct bulk Publishing to Web nodes provides access more efficiently than sharing to NFS. NFS is one of the most commonly used data storage services in the current Internet system architecture, and small and medium-sized websites can
