Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to the implementation method of balanced home agent load among a kind of mobile network.
Background technology
At present, mobile IP v 6 is a kind of communication protocol that is applied in the mobile communications network.Can realize the mobility of mobile node in the IPv6 network based on this agreement.For example, when the IPv6 node when home network moves to field network, still can under the situation that does not change its home address, keep accessibility.
Down, generally include three kinds of entities in the mobile IP v 6 network environment, as shown in Figure 1, be respectively: mobile node, home agent and communication node will describe three kinds of entities respectively below.
Described mobile node is changed into another link access for inserting from a link, but still can keep the node of the accessibility of its home address.
Described home agent is the router on the moving nodes local link; Mobile node need be registered present care-of address to it, like this, left at mobile node under the situation of home link, home agent is intercepted and captured the message that mails to the moving nodes local address that sends on the home link, and the encapsulation back is dealt into the Care-of Address of mobile node registration by the tunnel.
Described communication node is the opposite end of communicating by letter with mobile node, and communication node can move, and also can fix.
In the mobile IP v 6 network, need find by home agent, processing procedures such as registration and data transmission guarantee that the mobile communication of mobile node normally carries out.
In the agent discovery process of local, when mobile node has moved out home link, the mobile node home agent on the home link that can try to find out.
In registration process, mobile node can be registered to the home agent of finding and select, be registered in the corresponding home agent with home address and address information, and can transmit the tunnel based on the data that described address information is set up between mobile node and home agent with oneself.
In data transmission procedure, mobile node and communication node carry out the exchange of data by the tunnel between the home agent of mobile node and discovery.
Find that for the dynamic home agent of supporting the phase I need to safeguard the Global Address List of all home agent on the home link on the described home agent, described tabulation is called home agents list.When mobile node transmit a request to the anycast address of home agent, any one receives that the home agent of request can send whole home agents list to mobile node.
Receive that the mobile node of described home agents list need select hometown-agent-address from this tabulation, afterwards, then register to corresponding home agent.Certainly, if registration failure, mobile node also can select next hometown-agent-address to register from this home agents list, that is to say that mobile node is a home agent that need to select registration in home agents list successively.
In the mobile IP v 6 network, the priority of home agent is configurable, in home agents list according to the priority descending of each home agent.Concrete processing mode is: all be provided with priority at each home agent, described priority value is propagated by the local proxy information option in the router advertisement message, in home agents list, the global address of the home agent that priority is the highest comes first of tabulation.
Because mobile node obtains home agents list by the home agent discovery procedure, and therefrom select hometown-agent-address successively, therefore, if the priority set-up mode is a static configuration, the home agent that priority is high always comes the foremost so, will cause all mobile nodes always to select same home agent, make the load meeting of this home agent constantly increase, and then become the bottleneck of mobile IP v 6 system.
Usually there is home agent to exist on the home link more than one, when wherein some (be arranged in home agents list first) reached the upper limit of the mobility binding number that can support, but in the agent discovery process of local, mobile node obtains home agents list, this home agent still comes first, mobile node still can select this home agent to register so, sends the Binding Update message.Because the mobility binding table is full, can refuse this register requirement so receive the home agent of this registration message.Mobile node can be filed a request by the next address in home agents list after receiving binding acknowledgement.This address might still be other global addresses or other home agent of same home agent.If same home agent, registration message still can be rejected so, if other home agent, registration can success so.
Like this, not only may cause mobile node can't choose suitable home agent in a long time, also make and to have introduced a large amount of extra message among the mobile network, increase the weight of the burden of the network and the network equipment.
Therefore, the order of each home agent just seems very important in home agents list, because it has determined mobile node to select the selection result of a home agent in proper order in numerous home agent.For effectively adjusting the order of home agent in tabulation, corresponding network manager normally bears unbalanced situation by manual inspection to find home agent, and avoids certain home agent overwork by the priority that reconfigures home agent.
Yet, mode one side layoutprocedure by manual configuration home agent priority is comparatively loaded down with trivial details, and in addition, the mode of this manual configuration can't in time be adjusted the order setting of each home agent in the tabulation, thereby, can't guarantee effectively still that at present each home agent load balancing shares.

Embodiment
Core concept of the present invention is in mobile communications network, dynamically adjust the priority of home agent according to the current load parameter of the home agent on the same link, thereby adjust the ordinal position of each home agent in home agents list, like this, when mobile node carries out the home agent selection, just can select different home agent, realize that each home agent load balancing shares.Described load parameter comprises the priority and the load information of home agent, and described load information can adopt the percentage load of home agent to weigh.
In the method for the present invention, the priority of home agent has determined its ordinal position in home agents list, and promptly the home agent that priority is the highest is arranged in first of home agents list.
Usually, the parameter information of the priority of decision home agent comprises:
1, the priority of home agent self;
2, the percentage load of home agent self, described percentage load are the current percent value of having selected the mobile node number and the mobile node number that home agent can be supported of this home agent;
3, the priority of other home agent self;
4, the load of other home agent self.
In the above-mentioned priority parameters, except the load of other home agent, other each parameter is the known parameters information in the home agent, and therefore, the load that the present invention only needs to obtain other home agent on this basis gets final product.
The present invention is the information on load that obtains described other home agent, just in router advertisement message, increased a new load option, can get access to the load parameter information of other home agent by described load option, thereby conveniently determine the priority of home agent.
Owing to mention in RFC2461: increasing a new option in router advertisement can not influence existing function, requires the later release of agreement may define new option type, and the recipient must ignore any option that can not discern, continues to handle this message.Therefore, the router in the mobile communications network can comprise described load option in router advertisement.Receive that for the home agent of supporting the dynamic priority configuration router advertisement that has this option should carry out predetermined process process of the present invention; For the router of not supporting the home agent function or do not support the router of dynamic priority configuration, receive the router advertisement message that comprises this option, this option can be left in the basket.
Among the present invention, the effect of the load option that increases in described router advertisement message comprises:
1, is used to declare the load parameter information of current home agent, promptly notifies the load parameter information of other home agent oneself;
2, ask other routers to carry this option to obtain corresponding load parameter information;
3, require other routers to adjust priority.
For this reason, the form of described load option comprises following field as shown in Figure 3:
The type field: type field, confirm whether be the load option by this field;
Length field Length:8 position signless integer, the length of user record option comprises type and length field, the value in this territory must be 1;
The S field: the request flag position, other home agent that are used for informing network send the router advertisement message of bringing onto load option;
The M field: the M position, priority adjustment sign, other home agent that are used for informing network increase its priority;
Reserved field Reserved: this territory is not fixed temporarily, and the sender must be initialized as 0, and the recipient ignores this position;
Load-factor field Load Factor: i.e. percentage load information field, be used to write down the current percentage load information of home agent, be specially: (the maximum mobile node number that can support on the quantity/home agent of the mobile node of having supported on the home agent) * 100.
In the method for the present invention,,, then trigger dynamic home agent priority layoutprocedure in case its percentage load has reached corresponding warning value for any one home agent in the mobile communications network.In this process, home agent just can utilize the load option in the described route announcement message, to other home agent request load parameter information of this home link, and can adjust the priority of this home agent based on the algorithmic rule of setting.
For the present invention there being further understanding, be described further below in conjunction with the specific implementation of accompanying drawing to method of the present invention.
The specific implementation of method of the present invention specifically may further comprise the steps as shown in Figure 2:
Step 21: home agent obtains the percentage load of home agent self;
The value of the percentage load of described home agent is: (the maximum mobile node number that can support on the quantity/home agent of the mobile node of having supported on the home agent) * 100;
In this step, mainly be whether the load information of checking home agent surpasses predetermined value, described load information can be percentage load, also can be the mobile node number (at this moment, each home agent load-bearing capacity unanimity) of setting quantity, or the like.
Step 22: home agent judges whether its percentage load surpasses predetermined warning value, if surpass, then execution in step 23, otherwise, continue execution in step 21;
The warning value of the percentage load of home agent can be configured according to actual needs, and for example, the default value of described warning value can be set to 75%;
Suppose, the percentage load warning value higher limit 75% of an acquiescence all is set on each home agent.Reached 75% when comparing with maximum mobile node numbers that it can be supported to the mobile node of its registration, then triggered the automatic priority of corresponding home agent and adjust mechanism, promptly execution in step 23.
Step 23: other home agent on the home link at this home agent place send the load parameter solicited message, with the load parameter information of other home agent of acquisition request, so that carry out the adjustment of home agent priority in view of the above;
In this step, can obtain the load parameter information of other home agent by route announcement message, the home agent that promptly triggers the dynamic priority adjustment at first can send the non-request multicast router declaration of carrying new load option;
In described load option, " s " bit (promptly asking bit) is set, be provided with this bit after, other home agent of receiving this load option can respond route announcement message;
For the router that receives this route announcement, if this router also is a home agent, and can support dynamic priority to adjust mechanism, so, just this load option information can be processed;
When receiving this router advertisement message, all home agent on home link all can be handled described load option, can check " s " bit, send router advertisement in response; In response RA (route announcement), can comprise the load option of the percentage load that has current response router.
Step 24: after obtaining the load parameter information of described other home agent, just can be according to the load parameter information of other home agent (being information such as the priority of home agent and percentage load), each home agent on the same home link is carried out the adjustment of priority, and the adjustment of each home agent being carried out priority is to realize by the priority of adjusting each home agent;
Usually, trigger the home agent that priority is adjusted for sending a request message, after waiting for largest request route announcement delay interval time MAX_SOLICITED_RA_DELAY_INTERVAL duration, just can start corresponding priority level and adjust processing procedure, promptly the priority of home agent be adjusted;
The processing method of concrete adjustment priority is as shown in the table:
| The priority of this local agency's priority and other home agent of receiving is compared | This local agency's the load and the percentage load of other home agent are compared | Adjust processing mode | |
| 1 | High | High | The priority of self is changed to minimum value, for example, the minimum value in minimum value or all home agent. |
| 2 | High | Equate | The priority of self subtracts 1 |
| 3 | High | Low | Need not revise |
| 4 | Equate (non-0) | High | The priority of self subtracts 1 |
| 5 | Equate and be 0 | High | The unicast router that sends the bringing onto load option is declared to the minimum node of load." M " bit is set in the option." S " bit is not provided with.If many home agent that identical load percentage (for example 0%) is arranged select one of them to send unicast router declaration so at random. |
| 6 | Equate | Equate | Need not revise |
| 7 | Equate | Low | Need not revise |
| 8 | Low (non-0) | High | The priority of self subtracts 1 |
| 9 | Low (0) | High | The unicast router that sends the bringing onto load option is declared to the minimum node of load." M " bit is set in the option." S " bit is not provided with.If many home agent that identical load percentage (for example 0%) is arranged select one of them to send unicast router declaration so at random. |
| 10 | Low | Equate | Need not revise |
| 11 | Low | Low | The priority of self is added 1 |
Any home agent of the load option that is provided with the M bit of receiving all will add 1 to the priority of oneself.Before increase, can also once check again, whether see that the load of oneself is lower than the load of the home agent that sends this option.Have only when the load of oneself is lower than the home agent that sends this load option, priority adds 1 again.
The above-mentioned adjustment process of process can be that each home agent on the same home link carries out the adjustment of priority again, and can adjust the order of the home agent in the home agents list based on the priority of new home agent.
Step 25: through after the above-mentioned processing, mobile node is selected corresponding home agent successively according to the ordinal position of each home agent in the home agents list after obtaining described home agents list by the home agent discovery procedure.
In sum, if the router of mobile communications network can be supported the dynamic priority adjustment, realization then of the present invention can effectively dynamically be adjusted as the load on the router of home agent, and no longer need the network manager manually to follow the tracks of, adjust network load by the priority that reconfigures home agent.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
