Embodiment 2
The embodiment of the present invention additionally provides a kind of method for configuring route exclusively enjoying cloud main frame, as shown in Figure 3, comprising:
201, the request message that request end sends is received; Request message is used for request and carries out network activity.
202, according to request message, the IP address of request end is obtained.
203, according to routing table rule, the IP address of request end is forwarded on the host of carrying cloud main frame; Host is physical server and the network of application Intranet 172 network segment.
204, on host, private network is set up; Wherein, host is on IP address of internal network.
Concrete, during initial design internet, for the ease of addressing and stratification tectonic network, each IP address comprises two identification codes (ID), i.e. network ID and host ids.And the All hosts on same physical network all uses same network ID, the main frame (comprising work station on network, server and router etc.) on network has a host id corresponding with it.The Internet committee defines 5 kinds of IP address class types with the network of applicable different capabilities, i.e. category-A ~ E class.
Wherein this 3 class IP address class type (as shown in table 1 below) of A, B, C is distributed unitedly in the world by InternetNIC, and D, E class is special address.
Table 1
Concrete, public address (or being called public network address), so-called IP address is exactly to 32 bit address of each connection host assignment on the internet.
And IP address class is like telephone number (address code): the telephone number having had someone, you just can converse with him.Equally, there is the IP address of certain main frame, this main-machine communication that can be corresponding with this IP address.
According to TCP/IP (Transport Control Protocol/Internet Protocol, transmission control protocol/Internet protocol) agreement regulation, IP address binary system represents, each long 32bit in IP address, bit is converted into byte, is exactly 4 bytes.Such as one the IP address adopting binary form is a string very long numeral, and such user deals with hard and bothers.The conveniently use of user, IP address is often written to metric form, the middle byte using symbol ". " separately different.So IP address above can be expressed as " 10.0.0.1 ".This representation of IP address is called " Dotted decimal notation ", and this is obviously than 1 with 0 easily remember many.
At present, the computer that most of user thinks can only have an IP address, and this viewpoint is wrong.We can specify a computer to have multiple IP address, therefore when accessing the Internet, do not think that an IP address is exactly a computer; In addition, by specific technology, multiple servers also can be made to share an IP address, and these servers seem just as a main frame user.
IP address be divide into network number and host number two parts, designer just must determine every part comprises how many positions.The figure place of network number directly determines the network number (computational methods 2^ network number figure place) that can distribute; The figure place of host number then determines host number (computational methods 2^ host number figure place-2) maximum in network.But, the network size comprised due to whole the Internet may be larger, also may be smaller, designer is finally clever have selected one scheme flexibly: IP address space is divided into different classifications, and each class has different network number figure places and host number figure place.
IP address is the foundation of transfer of data in IP network, and it identifies a connection in IP network, and a main frame can have multiple IP address.IP address in IP grouping remains unchanged in Internet Transmission.
The basic format of IP address: IP network of today uses 32 bit address, represents, as 192.168.0.1 with dotted decimal notation.
Address format is: the IP address=network address+host address or the IP address=network address+subnet address+host address.
The network address is that the ICANN (the Internet Corporation forAssigned Names and Numbers) of Internet Society distributes, under to have the InterNIC of responsible north America region, be responsible for the RIPENIC of European Region and the APNIC object of the responsible Asian-Pacific area be global uniqueness in order to ensure the network address.Host address is distributed by the system manager of each network.Therefore, in the uniqueness of the network address and network, the uniqueness of host address ensure that the global uniqueness of IP address.
The address assignment of IP address:
According to the difference of purposes and security level, IP address can also be roughly divided into two classes: public address and private address.Public address uses in Internet, arbitrarily can access in Internet.Private address can only use in internal network, only has and could be communicated with Internet by proxy server.
IP address is divided into five classes, and category-A is reserved to government organs, and category-B distributes to medium scale company, and C class distributes to the people of any needs, and D class is used for multicast, and E class is used for experiment, and all kinds of open ended address number is different.
A, B, C tri-feature of class IP address: when being write IP address as binary form, first of category-A address always 0, the front three always 110 of the front two of category-B address always 10, C class addresses.
Category-A address
(1) category-A address the 1st byte is the network address, and other 3 bytes are host address.First of its 1st byte is fixed as 0;
(2) category-A address network scope: 1.0.0.0---126.0.0.0;
(3) private address in category-A address and reserved address:
1. 10.X.X.X is private address (so-called private address is exactly do not use on the internet, and is used in the address in LAN).
Scope (10.0.0.0---10.255.255.255).
2. 127.X.X.X is reserved address, is used as loop test.
Category-B address
(1) category-B address the 1st byte and the 2nd byte are the network address, and other 2 bytes are host address.The front two of its 1st byte is fixed as 10.
(2) category-B address network scope: 128.0.0.0---191.255.0.0.
(3) private address of category-B address and reserved address:
1. 172.16.0.0---172.31.255.255 is private address.
2. 169.254.X.X is reserved address.If your IP address is automatic acquisition IP address, and you do not find available Dynamic Host Configuration Protocol server on network.One of them IP will be obtained.
191.255.255.255 be broadcast address, can not distribute.
C class address
(1) C class address the 1st byte, the 2nd byte and the 3rd byte are the network address, and the 4th byte is host address.The front three of other 1st byte is fixed as 110.
(2) C class address network scope: 192.0.0.0---223.255.255.0.
(3) private address in C class address:
192.168.X.X be private address, scope (192.168.0.0---192.168.255.255)
D class address
(1) D class address is regardless of the network address and host address, and first four of its 1st byte are fixed as 1110.
(2) D class address realm: 224.0.0.0---239.255.255.255.
E class address
(1) E class address is regardless of the network address and host address, and the first five position of its 1st byte is fixed as 11110.
(2) E class address realm: 240.0.0.0---247.255.255.255.
If IP address only uses category-A, category-B, C class, D class and E class to divide, a large amount of wastes can be caused: a network having 500 main frames, cannot use C class address.If but used a category-B address, more than 60,000 host address would only have 500 to be used, and causes a large amount of wastes of IP address.Therefore, VLSM (Variable LengthSubnet Masking: VLSM) technology is also supported in IP address, can on the basis of category-A, category-B and class c network, Further Division subnet.
Based on above-mentioned thought and design concept, in the present embodiment, specifically the IP network based on every class is divided into subnet, and each subnet is defined; Wherein, described IP network and described subnet include category-A, category-B, C class, D class and E class;
Then new subnet address is distributed for each described subnet; Wherein, described subnet address is that the host machine part of using based on the network address of every class creates.
Concrete, sub-network division is defined as follows: Internet organization defines five kinds of IP addresses, has A, B, C tri-class address.Class A Network has 126, and each Class A Network may have 16777214 main frames, and they are in same broadcast domain.And in same broadcast domain, having so many nodes to be impossible, network can be saturated because of broadcast communication, and result causes 16777214 address major parts not dispense.IP network based on every class can be divided into less network further, each subnet is defined by router and distributes a new subnet network address, and subnet address is that the host machine part of using based on the network address of every class creates.
Further, in the application, specifically the IP network based on every class is divided into subnet, and after each subnet is defined, automatically distributes new subnet address for each described subnet; Wherein, automatic distributing IP is dynamic IP, and the manual setting in correlation technique is static IP, in the application, use dynamic IP to be to solve the not enough problem in IP address, or computer environment is not fixed, such as often having external staff to come company needs with network, each all want webmaster to go to the complicated operation of setting and loaded down with trivial details, and at webmaster not in case, namely this Migrant women can not use the problem of network.
Static IP is more stable network environment, and use when the abundance of IP address, certain the application also can use static IP.
205, in private network, be cloud host assignment private network IP address.
Concrete, in described private network, in every platform host, be described cloud host assignment C class private network IP address with subnet; Wherein, private IP address scope is: 192.168.0.0--192.168.255.255, and maximum host number has 255.
Such as, C class address is belonged to the IP of host distribution to when, public ip address scope is: 192.0.1.1-223.255.254.254, maximum host number has 2,090,000, in every platform host with subnet to cloud host assignment C class private network IP address, private IP address scope is: 192.168.0.0--192.168.255.255, and maximum host number has 255.A private network IP=532950000 IP address, 2090000 public network IP × 255, the Class C IP address that altogether can use just has 532950000.Therefore the collocation method available IP-addresses aboundresources more of the prior art of dynamic routing in use the present embodiment, and saving resource.
206, according to routing table rule, the IP address of request end is forwarded on the IP address of the privately owned Intranet of cloud main frame from the work IP address of internal network of host, so that the cloud main frame request message corresponding to the IP address of request end processes; Wherein, the IP address of the privately owned Intranet of cloud main frame is that it creates by host, and host and cloud main frame are in the different Intranet network segments.
A kind of method for configuring route exclusively enjoying cloud main frame that the embodiment of the present invention provides, comprising: receive the request message that request end sends; Request message is used for request and carries out network activity; According to request message, obtain the IP address of request end; According to routing table rule, the IP address of request end is forwarded on the host of carrying cloud main frame; Host is physical server; According to routing table rule, the IP address of the request end on host is forwarded on cloud main frame, so that the cloud main frame request message corresponding to the IP address of request end processes; Wherein, host and cloud main frame are in the different Intranet network segments, with in correlation technique because cloud host number is a lot, need to take a large amount of public network network segment IP, make IP resource inadequate, and a large amount of cloud main frames take whole network segments, also result in the waste of resource; And, underaction, when the cloud host ip of on host needs migration time, all cloud host ips on server all need the routing configuration scheme adjusted to compare, its host and cloud main frame (are private Intranet network segment IP cloudlike main frame not in the same network segment, host is the Intranet network segment IP of work, the IP address of host can not become), save public network IP resource, and when there is migration in the IP of cloud main frame or IP needs to adjust, can not affect routing rule and host IP, flexibility is better.
Advantage of the present invention:
1, to cloud host assignment is subnet net IP, is dynamic IP allocation, and does not need staff's manual assignment cloud host work network segment IP;
2, saved IP resource: cloud main frame is Intranet IP, host is public network IP, and the IP address of host can not become, and when migration occurs the IP of cloud main frame or IP needs to adjust, can not affect routing rule and host IP;
In traditional method, host and cloud main frame are in the same network segment, and such as host and cloud main frame all distribute C class public network IP address, then the most multipotency of host quantity together with cloud main frame reaches 2,090,000; If host distributes the public network IP address of C class, the public network IP according to C class sets up private network, and to cloud host assignment private network IP address, then the most multipotency of host and cloud host number reaches 53,295 ten thousand.
