Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
The inventive method can be divided into three big steps: 1) Website server information gathering; 2) Website server information is transmitted; 3) twice measurement obtains the link bidirectional performance.Have in central server S deploy in the present embodiment:
The database function module is used to deposit Website server information;
BGP (Border Gateway Protocol Table, exterior routing protocol routing table) functional module imports the global bgp routing table of any AS inner boundary router, realizes the mapping of IP address to the AS number;
The DNS functional module, the mapping function of AS number is arrived in the IP address of using the BGP functional module to provide, analysis service to domain name * .ip2server.sasm4.net and * .ip6server.sasm4.net is provided, and two domain names are responsible for the mapping that Website server information in the same autonomous territory is arrived in IPv4 address and IPv6 address respectively;
The HTTP functional module provides diversified inquiry service with the mode of website.
The flow chart of the method for the invention comprises as shown in Figure 1:
Step S101, the site information of Website server on the collection Global Internet, site information comprises: IP address, domain name, AS number, homepage page-size, homepage downloading rate.Site information is listed with the form of domain name tabulation.IP address and domain name are used for unique identification one station server jointly.Be used for the managing web server info for AS number, server is carried out cluster.Homepage page-size and downloading rate are used for the identification server performance.Acquisition mode specifically comprises following 5 kinds:
1, inquiry whois database, WHOIS (pronounces " Who is ", but not abbreviation, being to be used for transmission of Information agreements such as the IP of nslookup and the owner) database provides the authoritative database of information such as nslookup, IP prefix, AS number, by the AS information in the inquiry whois database, can obtain these AS administrative staff's Email address.After parsing the mail server in the Email address, deposit the domain name tabulation in.The limitation of this way is to obtain the mail server domain name, and a large amount of common net site servers are not mail server, and this method can't be gathered this part server info.
2, search each AS homepage, FixedOrbit is that the information that provides comprises the homepage of AS by the website that AS information is provided of non-profit organization's management.But not all AS has homepage, and the part website lost efficacy, so this method can only obtain part Website server information.
3, utilize search engine to collect site information, be called keyword search Google, collect the Website server in preceding two pages of return results with the AS name.This method can only passively be obtained server info, and controllability is not strong.
4, extensive style is searched, and extensive style is searched to mean and found out Website server as much as possible and do not consider whether these Website servers are distributed in different AS.The domain name source that native system uses is www.dmoz.org.This method can obtain a large amount of Website servers, but efficient is lower.
5, the user submits site information to.When the user finds an individual character can better Website server, can submit the information of this server to, central server deposits new Website server in the domain name tabulation in.This method uses the website to offer the interface of user's submission data.
Step S102, the domain name tabulation among the traversal step S101;
Step S103, the validity of the website that checking is gathered, if effectively, then execution in step S104 if the invalid continuation of current site travels through above-mentioned domain name tabulation, finishes until traversal.
Step S104 deposits effective site information in the site information database.Above-mentioned 5 kinds of methods all can not obtain web servers all on the present the Internet, and cut both ways.In order to obtain maximum Website server information, the present invention has realized this five kinds of methods, and the domain-name information of collecting is deposited in the same site information database.This method adopts MySQL as stored data base, and IPv4 is stored in respectively in the different forms with the IPv6 server, and an information of the corresponding domain name of each list item of form comprises:
Ip, the IP address of Website server is adopted DNS Protocol to resolve domain name and is obtained;
Webdomain, the domain name of Website server;
Asn, the AS number at the place, IP address of Website server;
Pagesize, by the page-size of the direct download site homepage of domain name, unit is byte (byte);
Bw, the speed of download when downloading webpage obtains divided by download time with page-size, and unit is byte per second (B/s).Speed of download is for weighing the foundation of server performance, and speed of download is fast more, and performance is good more.
Table 1 is the tableau format and the partial data of storing IP v4 Website server, and it is as follows to select in the AS4538 five different Website servers of best performance by the SQL query statement:
The database table lattice structure and the sample data of table 1 storing IP v4 Website server
For the ease of inquiring the information of the best Website server of performance, also comprising Website server is sorted by performance, deposit database after the ordering in.
Step S105 by the site information of DNS transmission Website server, is the best Website server of performance in the described IP place AS with arbitrary IP map addresses, and the fastest website of speed of download is the best website of performance; Specifically comprise:
Central server S receives DNS inquiry back earlier from extracting the IP address, finds under this IP AS number according to bgp routing table, inquires about the MySQL database then and obtains Website server information in this AS, at last this information is returned.Wherein, IP finishes at the central server end to the inquiry of Website server to AS and AS, and the user only needs a step can realize the function of query web server.Generally use at present the technology of fictitious host computer, realize that an IP address provides the website service of a plurality of different domain names.This just causes only can't determining a Website server by the IP address, the domain-name information of this server also need be provided.Native system returns IP address and domain-name information simultaneously when returning Query Result, A or the AAAA class resource record among the DNS adopted in the IP address, and category-A is represented the IPv4 address, and the AAAA class is represented the IPv6 address; Domain-name information returns by the CNAME resource record.
In order to realize step inquiry, need the mapping of realization from IP to AS.Therefore the corresponding relation that contains IP address and AS number in the AS PATH attribute of bgp routing table item need obtain bgp routing table to realize this mapping.The present invention selects for use the route software Zebra that increases income to build bgp router, obtains whole bgp routing table in real time by communicating by letter with education network trunk bgp router.
The present invention selects for use open source software BIND (Berkeley Internet Name Domain) that DNS is provided service.User's inquiry is responsible for resolving and handling by BIND.For this reason, BIND need obtain bgp routing table, promptly realizes communicating by letter of BIND and Zebra, and this method is come communication between implementation process by shared drive.Routing table among the Zebra is left in the shared drive, and BIND visit shared drive can obtain routing table.Obtained the affiliated AS of IP, BIND only need inquire about the MySQL database can obtain Website server information.
The user is when the query web server info, earlier the counter-rotating of IP to be checked address is embedded in the nslookup, the domain name of IPv6 is ip6server.sasm4.net, and the domain name of IPv4 is ip2server.sasm4.net, and the authoritative server of these two domain names is central server S.Fig. 2 is for being the querying flow figure of example with the IPv6 inquiry.Be the use-case of IPv4 and IPv6 inquiry below:
The IPv4 inquiry:
nslookup?1.1.111.166.ip2server.sasm4.net
Server：166.111.8.28
Address：166.111.8.28#53
Non-authoritative?answer：
1.1.111.166.ip2server.sasm4.net?canonical?name＝www.edu.cn.
Name：www.edu.cn
Address：202.205.109.205
Name：www.edu.cn
Address：202.205.109.208
Name：www.edu.cn
Address：202.112.0.36
The IPv6 inquiry:
nslookup-q＝aaaa?250.2001.ip6server.sasm4.net
Server：115.25.86.250
Address：115.25.86.250#53
Non-authoritative?answer：
250.2001.ip6server.sasm4.net canonical name＝www.cau.edu.cn.
www.cau.edu.cn?has?AAAA?address?2001:250:209:208::8025
As from the foregoing, Website server information can be correctly transmitted in the DNS service.Advantages such as the DNS service has and can expand, and load is light, but can only return finite information at every turn.For more information is provided, the present invention adopts the website that service is provided, as: domain name is search.sasm3.net.
Can step S106, central server judge whether inquiry is effective, promptly extract correct IP address from inquiry, if invalid, execution in step S107, if effectively, execution in step S108.
Step S107, ignored request.
Step S108, inquiry MySQL database obtains the Website server information in this AS, preferably obtains the best server info of performance.
Step S109 returns Query Result, promptly returns the best server info of performance in the AS.
Step S110 utilizes the HTTP functional module to inquire about the information of more Website servers on the search.sasm3.net of website.The service that the website provides has:
Return all Website server information in the place AS of described IP address according to the IP address;
According to all Website server information of inquiring about in the described AS for AS number;
According to all the Website server information in the corresponding IP place AS of inquiry of the domain name domain name.
The user submits the interface of Website server information to.
The information of returning also comprises Dmoz and measures interface in real time except website domain name and IP address.Above all functions are all supported IPv4 and IPv6 fully.
Step S111 utilizes the Website server information that obtains among described S109 and the S110 that network is carried out two-way link and measures.Network topology schematic diagram with Fig. 3 is the principle that example illustrates twice measurement below.
User A and B lay respectively at AS1 and AS3, and A passes through AS1, AS2 to AS3 to the path of B, and B passes through AS3, AS4 to AS1 to the path of A.Two paths might overlap, and also may not overlap, and this is because the opening of the Internet determines, each AS formulates the route in policy management oneself zone respectively, and this has just caused A not necessarily identical to the routing condition between the A to B and B.This reason has caused A different to the network link performance possibility of A with B to B just.For generality more being arranged, the different situation of the round route of having drawn here.Web1～web4 is respectively the Website server that is deployed in each AS.
The first step, user A use the traceroute instrument find from A to B each hop router of process; In second step, the DNS service that user A uses native system to provide is mapped as Website server in the corresponding IP place AS with each hop router, and that user A obtains among this figure is exactly Web1, Web2 and Web3, and user A passes to user B with this information; In the 3rd step, user B uses instrument such as wget to download webpage from Website server successively, can obtain the link performance from Web1, Web2 and Web3 to B, get wherein the poorest performance as A to the one way link performance between the B.In like manner, B adopts identical step, measures B to the link performance between the A.The process of Here it is bidirectional measurement.By measuring, the user can not only obtain A to the two-way link performance between the B, can also obtain the performance of each section link simultaneously, and the poorest link of performance is exactly the bottleneck place.
In some cases, have only a user to need the measure link performance, promptly can't find out a partner user B at network to be measured.In this case, A uses native system, can measure the one way link performance, obtains to have the result of certain guidance meaning.
As from the foregoing, use the present invention can measure the two-way performance of end-to-end link, and find out the bottleneck place, and do not need to dispose any measurement server, the cost of paying is that user both sides will measure.If have only a side user, then can only measure the one way link performance.Compare to dispose and measure the required cost of server, the method that native system uses has more practicality.
Above execution mode only is used to illustrate the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the spirit and scope of the present invention; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
