Description
Technical field
The invention belongs to data communication technology field, more particularly to a kind of network address conversion port distribution method and it is
System.
Background technology
NAT (Network Address Translation, network address translation) is proposed within 1994 for special
The internal host assignment of net arrived local ip address (specific address only used in this private network) afterwards and with internet
Main-machine communication (and need not encrypt) a kind of method.This method needs to be connected on the router of internet in private network
NAT softwares are installed.Router equipped with NAT softwares is called NAT router, its at least one effective external Global IP
Location.So, all main frames using local address will turn its local address on NAT router when being communicated with the external world
Change Global IP addresses, ability and Internet connection into.In addition, this represent more private by using a small amount of public ip address
There is the mode of IP address, it will help slow down the exhaustion of available IP address space.NAT can not only solve lP address shortages
The problem of, but also the attack from network-external can be effectively prevented from, hide and protect the computer of network internal.NAT
Implementation have three kinds, i.e. static conversion Static Nat, dynamic translation Dynamic Nat and port multiplexing
OverLoad.Static conversion refers to the private IP address of internal network being converted to public ip address, and IP address is to being one-to-one
, it is unalterable, some private IP address is only converted to some public ip address.By means of static conversion, it is possible to achieve
Access of the external network to some particular devices (such as server) in internal network.Dynamic translation refers to the privately owned of internal network
When IP address conversion is public IP address, IP address is uncertain, be it is random, it is all to be authorized to Internet's
Private IP address can random transition be any legitimate ip address specified.As long as that is, specify which home address can be with
Changed, and during by the use of which legal address as external address, it is possible to carry out dynamic translation.Dynamic translation can use
Multiple legitimate external address sets.When the legitimate ip address that ISP is provided is slightly less than the number of computers of network internal.It can use
The mode of dynamic translation.Port multiplexing (Port address Translation, PAT) refers to change outgoing packet
Source port simultaneously carries out port translation, i.e. port address conversion (PAT, Port Address Translation) is more using port
Road multiplex mode.The All hosts of internal network can share access of the legitimate external IP address realization to Internet,
So as to save IP address resource to greatest extent.Meanwhile the All hosts of network internal can be hidden again, effectively avoid coming from
Internet attack.Therefore, it is exactly at most port multiplex mode to be applied at present in network.NAT is used for private net address
When dynamic translation is public network address, it will usually substantial amounts of private net address is converted into one or several public network addresses, each is private
Network users can be assigned to a port number under a shared public network address and the address, and pass through the address and port numbers pair
Public network conducts interviews, and realizes access of a large amount of private users to public network.NAT servers can use five when carrying out port assignment
Tuple mode constructs mapping relations, as long as i.e. source address, source port, destination address, destination interface, protocol number any of which one
Difference, resource contention would not be caused.Five-tuple mode, which constructs mapping relations, can solve the resource contention of normal conditions, but
In the case that some comparisons are extreme, in such as application of common C/S model, the address and port of server are fixed or collected relatively
In, then private user source port, destination address, destination interface, protocol number all same, the now corresponding interior entoilage of a port
Location, a public network address only have 65535 ports, and wherein many ports will also be left special applications in addition, therefore can divide
The quantity matched somebody with somebody is very limited, and existing following two technologies carry out the acquisition of port resource：NAT servers are using the method traveled through
To obtain port, by port designations to have taken after acquisition, such a method can be taken a substantial amount of time to be traveled through, and Intranet
User is more, and performance is poorer, can have a strong impact on the performance of NAT servers.NAT servers are obtained using the method for stochastic searching
Port (CN200810239058.6 [1]) is taken, it is a problem of hit rate occurs in the technology, more in Intranet Intranet user
In the case of still repeatedly to search and could realize hit, and all of the port can not be distributed, be reduced again in the case of resource-constrained
Available resources.
