Abstract

The invention relates to a port self-mapping routing technology. The application of internet is improved by adding a port self-mapping function to a router which is a key device of the internet. When external communication of an internal network host needs a port corresponding relation, the internal network host only needs to file an application to the router which automatically distributes a reasonable external network or public network port to the internal network host, requests a mapping relation between an internet protocol (IP) of the host and the port, and tells the distributed port and the external IP to the internal network host. By means of the port self-mapping routing technology, dependence on a server and management during internet application can be reduced, management complexity is reduced, safety is improved, pressure and waste of internet traffic, the server and a client side caused by using the polling technology are reduced or avoided, cost and threshold can be reduced and lowered for middle and small-sized enterprises and software designers, and flexibility is increased.

Description

Port is from shining upon route technology

Technical field:

Patent of the present invention belongs to electronics, the Internet and software field, by Interworking GateWay button apparatus---and-router increases port and improves internet, applications from mapping function, and the development of more low-cost promotion software and the Internet more.(note: port mapping also claims port repeat, a certain port that is about to router correspondence with foreign country is set up one-to-one relationship with internal a certain IP and port of communicating by letter, below identical)

Background technology:

1. existing route device all provides port mapping function, but can set after generally needing to know the account executive of router and password login, simultaneously because this is based on unified management pattern, keeper or know arbitrarily account and password can set per capita arbitrary port and any mapping relations of Intranet IP, there is in a way certain potential safety hazard, and can have more complicated management and safety problem when multiple route.

2. there is in the market Intranet port mapping software, but its most principle of products are set after being still and realizing software login by the acquiescence account of known various brands router and password, this situation can not be effective after account password is revised, although some software is even used the technology of decryption inadvisable standard.

3. current internet, applications majority needs the support of server, but more application can adopt point-to-point pattern, as application such as video conference, chat, file transfer, and this class application at present still needs the early support of reliance server, as technology such as typical " UDP burrow ", and most employing " poll " technology keeps, and communication link middle port is known all brings burden and waste to a certain degree with linking up to internet traffic, server and client side.

4. existing dynamic territory analyzing technology can solve dynamic IP to a certain extent on the impact of writing to each other, but still needs server support and domain name and poll.

Summary of the invention:

The present invention increases a kind of port from mapping function to existing route device technology, when intranet host correspondence with foreign country needs port corresponding relation, intranet host only need be filed an application to router, and router can according to request, from trend, it distributes rational port mapping relation the port of getting that can accuse and external IP.

Technical solution of the present invention:

1. the built-in request-reply handling procedure of router, when intranet host gives reply process when it is sent to request.As: when the main frame that Intranet IP is 192.168.0.5 sends " http: // 192.168.0.1/duankou.cgi localport=10000 & hopeport=20000 " access, router attempts setting up the mapping relations of " outer net IP:20000<==>192.168.0.5:10000 " automatically, if the information such as these intranet host mapping relations of successful announcement and outer net IP, if accuse failure otherwise 20000 ports take or do not meet standard, above formula is only example, reality can be processed as the case may be, if press standard designated ends slogan by router as omitted hopeport parameter in above formula.

2. in the expanded application of multiple route, bottom route can possess Forward-reques function, also can be to upper strata routing forwarding from mapping request when the outer net Intranet port mapping of setting up self is related to, and overlying roaduay is by similar processing, finally can be to public network IP: port.

3. intranet host can be set up the effect of similar service device by the fixedly mapping relations of the outer net IP that obtains and port, outer net main frame can carry out direct communication by this IP and port and this intranet host, the communications such as typical as can tell the other side by modes such as phone, mails by outer net IP and the port of this acquisition, the other side can transmit file after connecting, participate in a conference.

4. router can be set and can carry out between the ports zone of mapping, and as acquiescence from 10000 to 30000 Wei Zi mapped port districts, all the other are Random Maps ports zone.

5. it is spendable from mapped port quantity that router can be set every main frame of restriction, as limit 1000 in case maliciously take.

6. router can be set the recovery time from mapped port inactive state, as 30 minutes.

Port from map operation can give tacit consent to without account, password without login router direct control.

8. port is taked by router from intranet host IP in mapping parameters in communication process, has man-to-man fail safe.

Even for part router also can be based on managerial demand monitoring from mapped port district or convergent-divergent quantity close this function.

Beneficial effect of the present invention: the present invention utilizes port can reduce the dependence to server and management in internet, applications from shining upon route technology, can reduce management complexity and improve fail safe, also can reduce or avoid because using polling technique to internet traffic, server and client side's pressure and waste simultaneously, for medium-sized and small enterprises and software developer, also can reduce costs and threshold, increase flexibility.

Claims

1. port is from shining upon route technology, by to Interworking GateWay button apparatus----router increases port and improves internet, applications from mapping function, when intranet host correspondence with foreign country needs port corresponding relation, intranet host only need be filed an application to router, and router can according to request, from trend, it distributes the mapping relations between rational outer net or public network port and requesting host IP and port the port of getting that can accuse and external IP.

2. according to the port described in right 1, certainly shine upon route technology, emphasis is characterised in that: without account, password or login, intranet host only need send easy access request or order to router can completing port mapping relations.

3. according to the port described in right 1, certainly shine upon route technology, what have eigen is one of its embodiment: at port router in mapping process, can distribute corresponding outer net port also can freely distribute port according to intranet host request.

4. according to the port described in right 1, certainly shine upon route technology, what have eigen is one of its embodiment: port can have transfer characteristic from mapping, in multiple routed environment, may need to carry out multiple mapping and just can reach demand.

5. according to the port described in right 1, certainly shine upon route technology, what have eigen is one of its embodiment: port can be applicable to localized network as enterprise network, metropolitan area network etc. from shining upon route technology, also can be applicable to wide area network, the Internet etc.
