1) packet and the FIN that send the three-way handshake of TCP wrap, and simulation connects;
2) on the TCP connection basis, send the HTTP request, connect;
3) obtain the time that packet returns, the shortest IP address of time spent obtains connecting.
Bind-utils is one group of DNS kit that bind software provides, these instruments dig in the tool using bag, host; Nslookup; Nsupdate inquires about the IP that obtains domain name to different authoritative servers, thereby can carry out domain name mapping and DNS debugging work.The IP address that obtains is carried out three times of TCP respectively give out a contract for a project and the FIN bag, and HTTP connects work; Computing time, can obtain the shortest IP address of the time of connecting.
Described domain name is set up the domain name analytic method that HTTP is connected with server; Obtain after the shortest IP of the time of connecting; Ttl value is set as required sets up a RR (resource record), import to buffer memory, to the exploitation once more of DNS source code; Domain name, IP and ttl value are changed into inner operated NAME (domain name), RDATA (record value); Obtain a complete resource record setting (Resource Record set, i.e. RRSET), allow storage and retrieval name at inner DNS DB (database) interface of CACHE (buffer memory).
The record of DNS in resolving inquiry all can be kept in the database of having set up, and comprises domain name, query time, place circuit and queries, can obtain the bigger domain name of queries according to database; The domain name of buffer memory kind derives extraction through rndc (the terminal control tool of DNS, main as control DNS process and configuration file thereof).Utilize domain name, ttl value, the circuit name, IP sets up the address caching record, is inserted into buffer memory through rndc, and cache object comprises one virtual type DNS data.A plurality of virtual type, will be through creating a plurality of circuits, different with one types with its caching process.
Useful good effect of the present invention:
1, domain name of the present invention is set up the domain name analytic method that HTTP is connected with server; Connect needed time the shortest IP address from domain name mapping to setting up HTTP through finding out one; Can accelerate the parsing time of this domain name greatly, so guarantee the IP address parse be visit the fastest.
2, domain name of the present invention is set up the domain name analytic method that HTTP is connected with server, and implementation is simple, and result of use is obvious, can significantly promote the speed that the user opens webpage, increases the visit capacity of website, improves the commercial value and the practical value of website.
