Description
Technical field
The present invention relates to network communications technology field, particularly relate to a kind of method for ensuring quality and device thereof by different network messages.
Background technology
IPv6 is the abbreviation of (Internet Protocol Version 6), also is known as the Next Generation Internet agreement, and it is a kind of new IP agreement that is used for substituting existing IPv4 agreement.What the Internet great majority of today were used is IPv4 (Internet Protocol Version 4) agreement, and still along with the continuous expansion of internet, applications scope, it also is faced with the crisis that more and more can not be ignored, for example address scarcity or the like.IPv6 proposes in order to solve the more existing problem and shortage of IPv4 just, and it has also proposed improvement, for example route aspect, configuration aspect automatically in many aspects simultaneously.But IPv6 also can not substitute IPv4 at once, IPv4 and IPv6 can co-exist in the environment in the quite a while, therefore must provide a kind of transit mechanism stably, existing transitional technology has IPv4/IPv6 dual stack technology and IPv6 tunneling technique etc.
Along with the development of IPv6, the local I Pv6 network (isolated IPv6 site) that some backbone networks that moved the IPv4 agreement are kept apart has appearred, in order to realize the communication between these IPv6 networks, must adopt tunneling technique.The IPv6 tunneling technique be exactly with the IPv6 packet as data encapsulation in the IPv4 packet, make the IPv6 packet go up transmission in existing IPv4 infrastructure (mainly being meant the IPv4 router).The tunnel is transparent for Source Site and purpose website, porch in the tunnel, router is encapsulated in the packet of IPv6 among the IPv4, the IPv4 address that the source address of this IPv4 grouping and destination address are tunnel portal and outlet respectively, at the tunnel exit place, the IPv6 grouping is taken out be transmitted to the purpose website again.The advantage of tunneling technique is the transparency in tunnel, and the communication between the IPv6 main frame can be ignored the existence in tunnel, and the tunnel only plays the effect of physical channel, so tunneling technique is used very widely to the initial stage of IPv6 evolution at IPv4.
Prior art is by QoS (Quality of Service, service quality) show that the performance that information is obtained when transmitting guarantees in data communication system, IPv4 and IPv6 network all have independently QoS quality assurance separately, for example the IPv4 separate network passes through eight TOS field (Type of Service octet, type of service field) the sign message priority reaches corresponding service quality; The IPv6 separate network reaches corresponding service quality by TrafficClass field (traffic class octet, stream type field) sign message priority.
The shortcoming of described prior art is to guarantee that IPv4 and IPv6 separate network can finish the quality message of corresponding message, but when the IPv6 message passes through the IPv6 network by IPv4 network or IPv4 message, whole packet as data encapsulation in new packet, and in new header, use the priority of acquiescence, and original priority can be dropped, and therefore can not reach the quality assurance of existing client requirement.

The network equipment 1 by the embodiment of the invention is at the heterogeneous networks intersection, it is the mapping that IPv6 and IPv4 network tunnel interface have been realized former message priority and new message priority, make original priority of messages still can be retained and embody, guaranteed the service quality of message.
Wherein, new message generation module 11 comprises that message encapsulation submodule 111 and/or message recover submodule 112, message encapsulation submodule 111 is used for when first network message enters the tunnel, and first network message is encapsulated as second a new network message as payload; Message recovers submodule 112 and is used for passing through second network at second network message, and the payload with second network message when going out the tunnel reverts to first a new network message.
Wherein, this network equipment 1 also comprises judge module 13, be used at first network and the second network intersection, judge whether first message priority is corresponding with second message priority, when judged result when being, then notify new message generation module to encapsulate, the new message that encapsulation produces has and former message corresponding priorities.

Wherein, this network equipment 1 also comprises corresponding relation preservation module 14, be used for preserving the message priority of first network of setting and the mapping table of the message priority in second network, the priority that new message generation module 11 is resolved according to priority parsing module 12 is preserved the message corresponding priorities that finds the module 14 by first network and the second network intersection from this corresponding relation, can satisfy the user wishes to use different priorities in heterogeneous networks requirement like this, for example the user wishes high priority in the IPv6 network and can allow to use lower priority in the IPv4 network.
As shown in Figure 2, be the flow chart of the embodiment of the invention by the method for ensuring quality of different network messages, the embodiment of the invention can not only be implemented in carries out the setting of message priority when former message enters the tunnel, also can carry out the setting of message priority when former message goes out the tunnel.This embodiment may further comprise the steps:
Step S201: when first network message enters second network by first network, resolve this first network message and obtain first message priority.
, promptly during the intersection of IPv6 and IPv4 network, resolve first network message and obtain first message priority by first network and the second network intersection at message.For example the IPv6 message need pass through the IPv4 network, then after the IPv6 message enters the tunnel, resolves the Traffic Class field of this IPv6 message, obtains the original priority of this IPv6 message; For example after the IPv6 message went out the tunnel by the IPv4 network, the TOS field that can resolve this IPv4 message obtained the original priority of this IPv4 message; If the IPv4 message passes through the IPv6 network, the TOS field of resolving this IPv4 message obtains the original priority of this IPv4 message.
Step S202: first network message is encapsulated as second network message, and second network message contains second message priority corresponding with first message priority.
When first network message enters the tunnel, first network message is added switching network or other heading that can transmit as payload in switching network, be encapsulated as second network message, this second network message contains second message priority corresponding with first message priority, wherein the realization in various tunnel is the heading difference owing to encapsulation, so the embodiment of the invention all can be used at various tunnels.When for example the IPv6 message is by the IPv4 network, the tunnel interface at IPv4 network place adds IPv4 or other heading that can transmit with the IPv6 message as payload in the IPv4 network, this newly-generated IPv4 priority of messages is corresponding with former IPv6 priority of messages.
Step S203: in second network, transmit described second network message according to second message priority.
For example the IPv6 message enters the IPv4 network, the TOS field of new IPv4 message then is set according to former IPv6 message priority, corresponding like this IPv6 priority of messages just has been mapped to the IPv4 header of encapsulation, therefore new IPv4 message together carries out corresponding queue scheduling and transmits control with other common IPv4 messages in the IPv4 network, guaranteed the service quality of relative users, for example original IPv6 message is that high priority message ef stream (reaches low delay, low packet loss ratio), the IPv4 message of the mapping corresponding encapsulation in back also is a high priority message ef stream, can accomplish preferentially to guarantee this user's quality requirement when passing through the IPv4 network; In like manner when the IPv4 message passes through the IPv6 network, the Traffic Class field of new IPv6 message is set according to former IPv4 message priority.
Step S204: when after second network message passes second network, returning first network, first message priority is set according to second message priority.At first resolve second network message and obtain second message priority, then the second network message decapsulation is generated first network message, the load restoration that is about to second network message is first network message, and this first network message contains first message priority corresponding with second network message.For example the IPv6 message returns the IPv6 network by the IPv4 network, and former IPv4 message is to leave the tunnel, then removes heading, and the payload of former IPv4 message is reverted to a new IPv6 message.When the IPv6 message passes through the IPv4 network, the tunnel interface at IPv4 network place adds IPv4 or other heading that can transmit with the IPv6 message as payload in the IPv4 network, by behind the IPv4 network this heading being peeled off payload to recovering the message of IPv6, so that in the continuous transmission of IPv6 network trunk, the new IPv6 priority of messages of this moment is corresponding with former IPv4 message priority.
The invention process also proposes a kind of situation that enters the 3rd network after second network message passes second network, need to the 3rd network message of this generation priority be set according to second message priority equally, be provided with regard to the step with regard to concrete, enter the 3rd network and to enter second network from first network identical from second network, promptly all be suitable for the setting of step S201-step S202.
Realized that by the embodiment of the invention original priority of messages still can be retained and embody, and has guaranteed the service quality of message after the heterogeneous networks conversion.
The embodiment of the invention is not limited only at the heterogeneous networks intersection, when entering the tunnel, first network message carries out the setting of message priority, carry out the setting of message priority in the time of also can after first network message is by second network, going out the tunnel, it is identical that both priority are provided with flow process, and difference is when first network message enters the tunnel first network message to be encapsulated as second network message as payload; Remove the heading of second network message when after first network message is by second network, leaving the tunnel, payload is reverted to first network message, so following examples describe when all message being entered the tunnel, and be example with IPv6 network and IPv4 network.
As shown in Figure 3, be the flow chart of the embodiment of the invention, may further comprise the steps for the method for ensuring quality that passes through different network messages of user's selection:
Step S301: judge whether second message priority is corresponding with first message priority.
Judge whether second message priority is corresponding with first message priority, when judged result when being, then carry out first network message is encapsulated as second network message, described second network message contains the step of second message priority corresponding with described first message priority, i.e. step S302-S303.At the heterogeneous networks intersection, when first network message enters the tunnel, whether whether the inquiry user needs according to this first message priority second message priority to be set, selected to reset by the user, the ensuring method that makes the user use the embodiment of the invention more flexibly to be proposed.
Step S302:, then resolve first network message and obtain first message priority if second message priority is corresponding with first message priority.
At the intersection of heterogeneous networks, after first network message enters the tunnel, resolve first network message and obtain first message priority.When for example the IPv6 message is by the IPv4 network, promptly after the IPv6 message enters the tunnel, resolve the Traffic Class field of this IPv6 message, obtain the original priority of this IPv6 message; If the IPv4 message passes through the IPv6 network, the TOS field of resolving this IPv4 message obtains the original priority of this IPv4 message.
Step S303: first network message is encapsulated as second network message as payload, and second network message contains second message priority corresponding with first message priority.
When first network message enters the tunnel, first network message is added switching network or other heading that can transmit as payload in switching network, be encapsulated as second network message, this second network message contains second message priority corresponding with first message priority, wherein the realization in various tunnel is the heading difference owing to encapsulation, so the embodiment of the invention all can be used at various tunnels.When for example the IPv6 message is by the IPv4 network, the tunnel interface at IPv4 network place adds IPv4 or other heading that can transmit with the IPv6 message as payload in the IPv4 network, this newly-generated IPv4 priority of messages is corresponding with former IPv6 priority of messages.
Step S304: in second network, transmit second network message according to second message priority.
For example the IPv6 message enters the IPv4 network, the TOS field of new IPv4 message then is set according to former IPv6 message priority, corresponding like this IPv6 priority of messages just has been mapped to the IPv4 header of encapsulation, therefore new IPv4 message together carries out corresponding queue scheduling and transmits control with other common IPv4 messages in the IPv4 network, guaranteed the service quality of relative users, for example original IPv6 message is that high priority message ef stream (reaches low delay, low packet loss ratio), the IPv4 message of the mapping corresponding encapsulation in back also is a high priority message ef stream, can accomplish preferentially to guarantee this user's quality requirement when passing through the IPv4 network; In like manner when the IPv4 message passes through the IPv6 network, the Traffic Class field of new IPv6 message is set according to former IPv4 message priority.
Step S305: when after second network message passes second network, returning first network, first message priority is set according to second message priority.Judge at first whether first message priority is corresponding with second message priority, when judged result when being, carry out that then second network message is encapsulated as first network message, wherein, first network message contains first message priority corresponding with second message priority.Judged result is for being, then resolve second network message and obtain second message priority, then the second network message decapsulation is generated first network message, the load restoration that is about to second network message is first network message, and this first network message contains first message priority corresponding with second network message.For example the IPv6 message returns the IPv6 network by the IPv4 network, and former IPv4 message is to leave the tunnel, then removes heading, and the payload of former IPv4 message is reverted to a new IPv6 message.When the IPv6 message passes through the IPv4 network, the tunnel interface at IPv4 network place adds IPv4 or other heading that can transmit with the IPv6 message as payload in the IPv4 network, by behind the IPv4 network this heading being peeled off payload to recovering the message of IPv6, so that in the continuous transmission of IPv6 network trunk, the new IPv6 priority of messages of this moment is corresponding with former IPv4 message priority.
Step S306:, then use default priority that first network message is encapsulated as second network message as payload if second message priority is not corresponding with first message priority.
When the same embodiment of the invention had also proposed to return first network after second network message passes second network, whether the inquiry user needed to be provided with according to second message priority method of first message priority.
Realized after the heterogeneous networks conversion by the embodiment of the invention, original priority of messages still can be retained and embody, guaranteed the service quality of message, and whether new message priority has been set according to the former message priority that obtains by user's decision, convenient for users.
The embodiment of the invention has also proposed two kinds of methods of resolving former message and obtaining former message priority, and accurate Analysis or fuzzy the parsing select to resolve former priority of messages for the user, further improve the flexibility that this access device uses.As shown in the table, corresponding relation for priority title, 8bits control bit and corresponding TOS and DSCP numerical value, DSCP (Differentiated Services CodePoint wherein, [0] distinguish code point) be the QoS criteria for classification of the Diff-Serv (Differentiated Service, [0] Differentiated Services) of IETF issue. it utilizes 6 bits and untapped 2 bit bytes that have used to distinguish priority by encoded radio.Wherein [0] cs and af/ef/be are that different modes carries out the mode that priority is represented, cs only uses front three to carry out a kind of mode that priority is represented, af/ef/be then uses six in the middle of eight to carry out priority to represent.
| Title | 8bits | TOS | Traffic Class | DSCP |
| be | 00000000 | 0 | 0 | 0 |
| ef | 10111000 | 184 | 184 | 46 |
| af11 | 00101000 | 40 | 40 | 10 |
| af12 | 00110000 | 48 | 48 | 12 |
| af13 | 00111000 | 56 | 56 | 14 |
| af21 | 01001000 | 72 | 72 | 18 |
| af22 | 01010000 | 80 | 80 | 20 |
| af23 | 01011000 | 88 | 88 | 22 |
| af31 | 01101000 | 104 | 104 | 26 |
| af32 | 01110000 | 112 | 112 | 28 |
| af33 | 01111000 | 120 | 120 | 30 |
| af41 | 10001000 | 136 | 136 | 34 |
| af42 | 10010000 | 144 | 144 | 36 |
| af43 | 10011000 | 152 | 152 | 38 |
| cs1 | 00100000 | 32 | 32 | 8 |
| cs2 | 01000000 | 64 | 64 | 16 |
| cs3 | 01100000 | 96 | 96 | 24 |
| cs4 | 10000000 | 128 | 128 | 32 |
| cs5 | 10100000 | 160 | 160 | 40 |
| cs6 | 11000000 | 192 | 192 | 48 |
| cs7 | 11100000 | 224 | 224 | 56 |
As above shown in the table because the priority of IPv6 Traffic Class field and IPv4 TOS field is one to one, as the be of IPv6 and IPv4 stream all be 00000000, ef stream all is 10111000.Wherein, accurate Analysis is among whole parsing IPv6 whole 8 characters of TOS among the Traffic Class and IPv4, obtains precedence information accurately, as af31; Also can only resolve the front three character of TOS among the front three character of Traffic Class among the IPv6 and the IPv4, for example for the priority tag mode of af/ef/be, if to be resolved to the front three character be 001 then can judge that this precedence information is that af1 or front three character are 100 then can judge that this precedence information is af4.
Further strengthened the flexibility of this method on priority is resolved by present embodiment, be user-friendly to.
As shown in Figure 4, the flow chart of the corresponding relation of message priority in first network and the message priority in second network is set for the embodiment of the invention, can satisfy the different requirements of user by this embodiment to different networks, for example the user is in original IPv6 network, it is low and packet loss is low to require message can reach time-delay, yet the user only requires but in the IPv4 network that packet loss is low get final product, therefore also needs according to customer requirements the former message priority and the new corresponding relation of message priority to be set.This embodiment may further comprise the steps:
Step S401: according to customer requirements the corresponding relation of message priority in the message priority and second network is set in first network, generates a mapping table.
Step S402: after first network message enters the tunnel, resolve first network message and obtain first message priority.
At the intersection of heterogeneous networks, after first network message enters the tunnel, resolve first network message and obtain first message priority.When for example the IPv6 message is by the IPv4 network, promptly after the IPv6 message enters the tunnel, resolve the Traffic Class field of this IPv6 message, obtain the original priority of this IPv6 message; If the IPv4 message passes through the IPv6 network, the TOS field of resolving this IPv4 message obtains the original priority of this IPv4 message.
Step S403: search the corresponding relation tabulation according to first message priority that obtains, obtain second message priority.
Search above-mentioned corresponding relation tabulation according to the first message message priority that obtains, obtain second message priority according to customer requirements, for example the user wishes in the IPv4 network priority transmission be stream, and the priority transmission of in the IPv6 network, flowing with ef, therefore the corresponding relation of ef stream and be stream is set at the network equipment of IPv6 network and IPv4 network intersection, and can obtain second message priority according to this mapping table is be stream.
Step S404: first network message is encapsulated as second network message as payload, and this second message priority obtains according to mapping table.
First network message is added switching network or other heading that can transmit as payload in switching network, recover former message by behind the switching network this heading being peeled off, so that former message is in the continuous transmission of former network trunk, wherein the realization in various tunnel is the heading difference owing to encapsulation, so the embodiment of the invention all can be used at various tunnels; When for example the IPv6 message is by the IPv4 network, the tunnel interface at IPv4 network place adds IPv4 or other heading that can transmit with the IPv6 message as payload in the IPv4 network, by behind the IPv4 network this heading being peeled off the message that recovers IPv6, so that in the continuous transmission of IPv6 network trunk; In like manner, the IPv4 message is identical with said process by the process of IPv6 network.
Realized after the heterogeneous networks conversion by the embodiment of the invention, original priority of messages still can be retained and embody, guaranteed the service quality of message, and by the corresponding relation of message priority in the message priority and second network is set in first network, can also satisfy the different requirements of user, can further facilitate the user and use heterogeneous networks.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
