Abstract
A method and device for connecting broadband network user into internet includes: to receive a request information of connecting user end devices into the Internet, to respond the said user end devices to connect it to the Internet according to the identifying information in the said request information. The invented method and device can realize correct networking, not changing network allocation of connecting user PC device, especially when turning a connecting technology to another one, against the rather complicated connecting technology at present IP network.
Description
Technical field
The present invention relates to a kind of method and apparatus with the broadband network user Internet access, relate more specifically to a kind of the configuration more complicated of existing IP network access technology, particularly when when a kind of access technology is used another access technology instead with the method and apparatus of broadband network user Internet access.
Background technology
At present, the method for user Internet access mainly contains three kinds, promptly passes through: (1) static configuration; (2) DHCP (DHCP); (3) point-to-point protocol that on Ethernet, realizes (PPPoE).Respectively they are described briefly below.
(1) static configuration (as shown in Figure 1).The user is to IP address, subnet mask and the dns server address of the ethernet nic configuration appointment of own computer, then this network card is connected to the access device 102 of local side, the access device 102 of local side also needs will be configured to corresponding to the network interface of this network interface card interface be in same subnet with the user, data forwarding with ustomer premises access equipment 101 arrives the Internet 103 then, simultaneously the user's interest data is sent to this user.The advantage of this cut-in method is: for access device 102, do not need too many agreement support just ustomer premises access equipment 101 can be inserted the Internet 103, reduced the complexity of access device 102, make this access device 102 that higher performance can be arranged.But the defective of this cut-in method also is tangible: first, for the user, these parameters of configuration of IP address, subnet mask, gateway address and dns server address fully, and need to understand these notions, this has just increased the requirement to user knowledge, for for the unfamiliar user of computer network, this is a relatively more disagreeable task; The second, for the equipment supplier, also need correctly to dispose these parameters, this has just increased the requirement of the technology that equipment management personnel is had, and has also increased the fund expenditure to equipment management personnel; The 3rd, when user's improperly-configured, often think that local side apparatus is out of order, usually inquire that this carries out the phone answer with regard to needing the equipment provider to need special personnel, has increased equipment provider's manpower by the mode of making a phone call; If problem still can not get solving, also need equipment provider personnel assigned to go to fix a breakdown, this has more increased equipment provider's expenditure cost.
(2) DHCP (as shown in Figure 2).The user need not give the parameters such as address of network interface card configuration of IP address, subnet mask and the dns server of own computer, and be to use DHCP (DHCP) technology to come to obtain the address of IP address, subnet mask, dns server, thereby be connected into Internet network 103 from Dynamic Host Configuration Protocol server.The advantage of this cut-in method is: for the user, do not need to compare complicated configuration, compare fairly simple with preceding a kind of cut-in method; The shortcoming of this cut-in method is: need the support of 102 pairs of DHCP agreements of access device, need to keep corresponding data record simultaneously, the complexity that this has increased equipment has reduced the performance of equipment.
(3) PPPoE (as shown in Figure 3).Because Ethernet is the network media of a shared bandwidth, to the controlled of unique user is not fine, and PPPoE (point-to-point protocol that is realizing on the Ethernet) is by the realization of simulation PPP on Ethernet, thereby strengthened on Ethernet individual consumer's control, in its solution, often needed to realize controlled function the user in conjunction with the Radius server.The advantage of this cut-in method is: the first, and can realize the checking of more intense user validation, can carry out charging unique user according to flow or duration to the user; The second, can realize more intense controlled function to independent user.The shortcoming of this cut-in method is: first, the configuration of this agreement is quite complicated, will be referred to a large amount of relevant configuration such as PPP, PPPoE, RADIUS, IP address pool, high to the computer network requested knowledge of equipment management personnel, this just need compare big expenditure to equipment management personnel; The second, therefore make mistakes extremely easily because configuration is complicated.
Comprehensive analysis to top 3 access technologies, as can be seen, no matter for being access in user 101 still is for the access device 102, configuration wherein all is a more complicated, if an access technology needs the user to change its network configuration, tend to so cause some mistakes, and this just causes the raising of access device 102 provider's maintenance costs, also can cause being access in the discontented of user.If do not change the correct configuration before the user so can try one's best, cause that so wrong chance will reduce greatly, also just means and has reduced maintenance cost.Therefore, if realized not changing access, have significant practical applications very much to what use the different access technologies Internet user.
Summary of the invention
In order to have realized that the different access technologies Internet user's do not change access to using, the objective of the invention is: no matter which type of broadband access technology the user who is inserted used be connected into the Internet in the past, as long as the once successful access the Internet of his/her PC, so under the prerequisite of the network configuration of not revising his/her PC, as long as the network interface of his/her PC and the network interface of access device of the present invention are correctly coupled together, his/her PC just can successfully insert the Internet so, obtains his interested resource.
In order to achieve the above object, the invention provides a kind of method that is used for the access device of broadband network user Internet access, wherein said method comprises: (1) receives the solicited message that ustomer premises access equipment inserts the Internet; (2), respond described ustomer premises access equipment, and it is inserted the Internet according to the type of the address information that comprises in the described request information.

In the present invention, concrete operational environment comprises a plurality of network nodes 104 of ustomer premises access equipment 101, access device 102, the Internet 103 and the desired visit of user.As long as on each interface of access device 102, enable whole 3 kinds of access technologies that surface analysis is crossed, the plug and play of the access customer that just can achieve a butt joint online.
For the ustomer premises access equipment 101 that has disposed IP address and gateway by static method, the IP address that is disposed, gateway and dns server address information all are invalid for access device 102, for such user can be surfed the Net, the IP address transition of ustomer premises access equipment 101 must be become so for access device 102 effective I P addresses, access device 102 must be with own as user's gateway pointed, and access device 102 also needs the DNS request of issuing invalid dns server (not shown) is effectively replied.As long as finished above-mentioned 3 work, ustomer premises access equipment 101 just can normally have been surfed the Net so.
In this case, angle from ustomer premises access equipment 101, because access device of the present invention is provided, the network parameter no matter this ustomer premises access equipment 101 disposed (local ip address, network ip address and subnet mask etc.) whether effectively, whether correct, all can realize having surfed the Net without barrier.
Below in conjunction with accompanying drawing the present invention is described in detail by the specific implementation that static configuration method inserts the Internet.
Fig. 4 is the schematic flow diagram of working as the source IP address that is disposed user Internet access 103 when invalid according to the present invention by static configuration method.Wherein arrow is represented the flow direction of datagram (packets of information that promptly comprises solicited message and other resource information) among the figure.
The invalid source IP address that the user disposed has very big difference, and this address may be privately owned address, also might be invalid public address, and luckily also might be identical, so this address does not possess in all senses.For an equipment (for example router) of realizing the 3rd layer of forwarding, be to use route to transmit, and the method for using the main frame route merely also is not enough to address this problem, so for subscriber equipment to be accessed 101 employed IP addresses, access device 102 all needs to use NAT (network address translation device, being used for an invalid IP address transition is an effective I P address in the TCP/IP network) technology is converted into a significant IP address in access device 102, and this address and this user 101 to be accessed are associated, and use this IP address that itself and other user to be accessed is distinguished.
In the present invention, when access device 102 receives that the user is sent to the datagram of the network node that is positioned at the Internet 104 of his desired communication, access device 102 replaces with the source IP address of the user datagram received in access device 102 can this user's IP address of unique identification, and in address correlation table (not shown) of before will changing and the IP address after conversion adding, then the network node 104 of this datagram to the desired visit of user sent.
When sending datagram, might carry out NAT conversion once more to this datagram, this will look access device 102 is used for discerning the IP address of inserting user 101 is the effective I P address the Internet in, still is invalid IP address.If effectively, when sending, can not send the NAT conversion so; If invalid, and the upstream equipment (not shown) that is positioned at access device 102 more close internet locations does not wish to receive that access device 102 also needed to carry out the NAT conversion before datagram is sent so when comprising invalid source IP address.
When after the network node 104 that is positioned at the Internet 103 is being received this datagram that is access in user 101, replying, the purpose IP address of its response packet will be the IP address after access device 102 conversions, so this reply data newspaper will send to access device 102, access device 102 takes out the invalid IP address that is access in user 101 that this datagram should send to again from the address correlation table of oneself setting up, replace the purpose IP address of this datagram and be correspondingly processed (NAT operation), send to then and be access in user 101.
Be access in sending datagram that user 101 just can success like this to the network node 104 that is positioned at the Internet 103, simultaneously can be from these network node 104 reception datagrams, thus communicate.
Fig. 5 is the gateway ip address that is disposed user Internet access 103 when invalid is worked as in explanation by static configuration method according to the present invention a schematic flow diagram.
For the invalid gateway address that the user disposed, when the user needs the access internet resource, because the node that institute's access resources is positioned at 104 and oneself be not on same subnet, so datagram needs gateway to carry out transfer, because inserting medium is Ethernets, the user need at first get access to the MAC Address of gateway again.If user's PC 101 does not have MAC (medium access control) address (the being physical address) information of gateway, the PC 101 that is access in the user so can send ARP (address resolution protocol) request of a purpose IP address for the gateway address that it disposed.Obtain the MAC Address of gateway when the arp reply of receiving gateway after, user's PC 101 is just understood the actual data of wanting to send to the network node 104 of his desired communication is sent to gateway, is transmitted by gateway again.
Because this gateway address is user configured invalid address, so there is not the network equipment can carry out arp reply, so the PC 101 that is access in the user can't obtain the MAC Address of gateway, this is access in the main frame that is positioned at the Internet that user 101 also just can't visit required with it and communicates so.
In this case, in the present invention, on access device 102, enable the ARP proxy function, although access device 102 does not know what user configured gateway address is, because the ARP request is broadcasting, so access device can be received this ARP request.Though the address of access device 102 is not the IP address in this ARP request, but this access device 102 is still made arp reply with the MAC Address of access device, and ARP proxy is all carried out in all IP addresses replys, the user will think that the MAC Address of access device 102 is exactly the MAC Address of the gateway of oneself like this, this access device 102 is access in the MAC Address that the data to the network node 104 of his desired communication that send after the user 101 all will send to this access device 102 like this, so just can carry out forwarding of data.
Fig. 6 is the IP address of the dns server that an is disposed embodiment of user Internet access 103 when invalid is worked as in explanation by static configuration method according to the present invention a schematic flow diagram.
When the application program of subscriber's main station 101 during, be based on that the IP address transmits because in IP network, communicate by letter, so must at first domain name be converted to the IP address by the network node 104 in the Internet of domain name access (Internet).Therefore user's main frame 101 at first can send the domain name mapping request to his name server (not shown) address that PC disposed, dns server returns lookup result then, if lookup result is for can not find, user 101 can not set up with this network node 104 and communicate by letter so.
If user configured dns server address is invalid, the user wants to communicate by letter with which network node that is positioned at the Internet 103 and will fail so.
In this case, in the present invention, in access device 102, enable the dns server function, make it with own dns server as user 101, after receiving the domain name mapping request, return DNS and reply to the user, soon the pairing IP of this domain name address returns to and is access in user 101, be access in user 101 like this and know the pairing IP of this domain name address, just can send datagram to this network node 104.
Fig. 7 is the IP address of the dns server that is disposed another embodiment of user Internet access when invalid is worked as in explanation by static configuration method according to the present invention a schematic flow diagram.
Under situation shown in Figure 7, access device 102 also can be realized the DNS relay function.As shown in Figure 7, the DNS request with the user is transmitted to a legal dns server (not shown).But because user's dns server address is invalid, so need to change the purpose IP address of datagram, with the purpose IP address modification in this DNS request is the correct IP address of configuration on the access device 102, behind the IP address of changing correct (effectively) into.Simultaneously because user's source IP address also is invalid, so also need to use the method for the invalid IP of said change user address, front that the inactive source IP address transition in the DNS request package of transmitting is the effective I P address.Then, this DNS request is sent to correct dns server (not shown).
The dns server (not shown) is searched after receiving request, and returns the result who finds.
Below in conjunction with accompanying drawing the present invention is described by the specific implementation that the DHCP method inserts the Internet.
Fig. 8 is the schematic diagram that the user inserts the Internet 103 by the DHCP method according to the present invention.
For the user who uses the DHCP online, because such user itself is without any the information about source IP address and gateway ip address etc., so solving his method of online is exactly the function that enables Dynamic Host Configuration Protocol server on the interface of access device 102,, ustomer premises access equipment 101 gets final product for distributing the information such as IP address of effective source IP address and gateway.At this moment, access device 102 need possess the function of Dynamic Host Configuration Protocol server or DHCP relay device.
In this case, the interface that is connected with subscriber equipment 101 in the access device 102 should be arranged in same subnet.
Below in conjunction with accompanying drawing the present invention is described in detail by the specific implementation that the PPPoE method inserts the Internet 103.
Fig. 9 is the schematic diagram that the user inserts the Internet 103 by the PPPoE method according to the present invention.
Use the user of PPPoE online, because PPPoE client 101 IP address is from the PPPoE server-assignment, so if the network type that user's PPPoE client software is bound is the type that access device 102 is supported, access device 102 can use address pool automatically to be user's distributing IP address so, like this, the user also just can surf the Net with not making any modification.
