When an access service gateway (AGW) transmits data messages, the last byte carries out the mod onthe number of a plurality of next hops according to IP addresses of IP-CS users or MAC addresses of ETH-CS users, thereby obtaining the numbers of the next hops. By adopting the invention, the data stream load can be shared according to the user granularity when the AGW starts a plurality of interfaces.
Description
Technical field
The present invention relates to the communications field, relate in particular to the method and the device of the data flow load sharing when enabling a plurality of interface of IAD in a kind of WiMAX system.
Background technology
WiMAX (Worldwide Interoperability for Microwave Access, micro-wave access global inter communication) is a wireless access wide band technology.Fig. 1 shows WiMAX network architecture reference model, by terminal (travelling carriage/fixed station)/access business network (ASN) be connected three logic entities of business network (CSN) and form.Terminal is the final service person of benefiting from; ASN is a common entity sets relevant with access service in the WiMAX network system; CSN is a service supplier for terminal provides the diverse network business.
Be connected by the R3 mouth between ASN and the CSN.(Base Station BS) forms with ASN gateway A GW (ASN GateWay, Access Service Network Gateway) ASN, is connected by the R6 mouth between BS and the AGW by the base station.Connect by the R4 mouth between the ASN.
In WiMAX uses, support the IP user to insert at present, support that also the ethernet user inserts simultaneously.Be used for Internet protocol convergence sublayer (Intemet Protocl convergence sublayer, IP-CS) during scene, the R3 mouth generally all connects Intemet by fire compartment wall, privately owned address field is adopted in the networking of fire compartment wall and AGW, AGW receive user-dependent access session request at first load sharing to corresponding fire compartment wall, and then via delivering to Intemet after the firewall network address conversion processing such as (NAT).
As shown in Figure 1, there are two kinds of user data messages in the R3 mouth: the user uplink data message receives after AGW handles from the R6 mouth and transmits from the R3 mouth; User's downlink data message receives after AGW transmits from the R6 mouth after handling from the R3 mouth.
When AGW adopted big capacity networking, AGW was configured to a plurality of interfaces, and the required fire compartment wall linking number of its capacity and user has surpassed the ability to bear of general low side fire compartment wall, needed this moment the high-grade fire compartment wall of configuration could satisfy actual requirement.And when networking is disposed, because the cost of high-grade fire compartment wall is too high, so in the actual application, consider to use many low fire compartment walls that dispose to reach the effect of high configuring firewalls with regard to being necessary.
When using many fire compartment walls to carry out networking, need to guarantee the consistency of user conversation, promptly AGW need guarantee that also the access request of a series of associated can keep being assigned on the fire compartment wall when multilink is carried out load balancing.Be the user on the whole AGW, can be according to user's granularity, user's message shared on a plurality of fire compartment walls transmit.
The present load sharing mode of operation of AGW in networking, the general relevant user information of not paying close attention to the message that sends, but each message is shared on many conversion links one by one, be that granularity is determined the load sharing strategy with the message when promptly transmitting, any like this fire compartment wall all might be received all users' message, and can't perceive user's whole transmission session (TCP, UDP session).
Fig. 2 has provided AGW separate unit fire compartment wall and has disposed and data flow load sharing situation.
As shown in Figure 2, in this networking was disposed, AGW had disposed two interfaces, and is connected to same fire compartment wall, promptly had two links between AGW and the fire compartment wall.AGW does not pay close attention to the relevant user profile of concrete message when data stream is carried out load sharing, according to the message granularity with polled ground of the data flow load sharing of user A and user B to each bar link.Though fire compartment wall can perceive user A and the whole transmission session of user B like this, but work as number of users more for a long time, the throughput of AGW will if continue to use this networking mode just need replace with high-end fire compartment wall, improve the cost that networking is disposed above the ability to bear of general fire compartment wall.
Fig. 3 has gone out many fire compartment walls of AGW to be disposed and data flow load sharing situation.
In networking shown in Figure 3 is disposed, adopt two low side fire compartment walls to replace high-end fire compartment wall required among Fig. 1, AGW does not change (still adopt and press message granularity poll) to the load sharing pattern of data flow, so the message of user A and user B all has been forwarded on the different links according to the order of sequence, cause each user's message all to be dispersed on the different fire compartment walls, fire compartment wall can receive all users' message like this, but can not receive all messages of certain user, so whole transmission session that can't the perception user.
In the practical application scene, when carrying out networking as if many fire compartment walls of employing, must realize the consistency of session like this, AGW need be distributed to specific user's session on the same fire compartment wall, externally will expose an address through the user behind the fire compartment wall NAT.
In addition, be transmitted to terminal use's downlink data message in the R6/R4 side for AGW, if all select stable forward-path at each user's message, also can make user's message flow obtain better QoS characteristic to a certain extent, and the message of same subscriber is gone out from same interface all the time, has also reduced the message that mails to terminal out of order possibility takes place.
The deployment scenario of actual AGW has certain characteristics, routed environment is simple relatively, route entry is less relatively, and route changes less, very little (the AGW interface and outreach switch and break down and just can produce route oscillation of the route oscillation of the last generation of AGW, the probability of routing change, belong to the concussion that fault causes), so AGW can simple process when selecting conversion link, only consider the processing under the route stable case.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method and device that is used to realize data flow load sharing when the WiMAX IAD is enabled a plurality of interface, be used for solving when adopting many fire compartment walls to carry out networking, the access request of a series of associated can't be kept be assigned on the fire compartment wall, realize technical problem based on the load sharing of user's granularity.
