Abstract
The invention relates to a seamless interface switching method for PMIPv6 (Proxy Mobile Internet Protocol v6) multi-connection mobile nodes, belonging to the field of PMIPv6. A mobile node is provided with a plurality of network interfaces which simultaneously access to the same PMIPv6 domain, when one network interface (assumed as IF1) of the mobile node is accessed to an MAG3 (Mobile Access Gateway 3) in the same PMIPv6 from an MAG1, data transmitted on the interface is firstly transmitted onto the MAG connected with other network interfaces of the mobile node, and then transmitted to the non-switching interface of the mobile node; and when an LMA (Lightspeed Memory Architecture) detects that the mobile node is leaving the MAG1, the LMA directly transmits the data flow onto the MAG connected with other network interfaces of the mobile node, thereby realizing seamless data transmission in the interface switching process of the mobile node.
Description
Technical field
The invention belongs to proxy mobile IPv 6 (PMIPv6) field, relate to the multi-link mobile node seamless interfacing of a kind of proxy mobile IPv 6 changing method.
Background technology
Along with the fast development of the Internet access technology and mobile terminal device, network-termination device often is equipped with a plurality of network interfaces, and the network domains that terminal accesses a plurality of isomeries has simultaneously become possibility.Simultaneously, increasing user wishes to enjoy anywhere or anytime the network insertion service, therefore is the inevitable requirement of Future Internet agreement development to ambulant support.Present IETF MIF(Multi-interface) working group is devoted to formulate the standardization of many interfaces related protocol mechanism.And be to satisfy user's demand of access network whenever and wherever possible, IETF has set up a series of related work groups to promote the standardization of mobile IP technology, be devoted to respectively the standardization of mobile IPv 4/IPv6 technology such as MIP4/MIP6 working group, Netext working group is devoted to standardization of network side mobility management protocol PMIPv6 etc.
With the mobile IPv 4 protocol class seemingly, mobile IPv 6 protocol has increased mobility support on the basis of IPv6 agreement.But Mobile IP needs the support of mobile node itself, needs to revise the protocol stack of mobile node, in actual applications, is difficult to determine whether mobile node supports mobile IP protocol.In order to guarantee that client need not any modification and also can enjoy the Mobile IP service, proxy mobile IPv 6 needs mobile management work to be processed to transfer in the network mobile node in the mobile IPv 6 protocol, network is all transferred in these work processed.Just can in network, move freely so that client need not any modification, and node address remains constant that node is to mobile complete unaware.At present the proxy mobile IPv 6 agreement is as next-generation full-IP mobile network's hot technology and by extensive concern.
RFC 5949 " the quick handoff technique of proxy mobile IPv 6 " has done standardization to proxy mobile IPv 6 mobile node interface switching flow, and this manuscript has proposed two kinds of quick handoff techniques of quick handoff technique: reactive and the quick handoff technique of predictive.These two kinds of handoff techniques all are by the Mobile Access Gateway (MAG) that connects before the mobile node interface switches and set up the mode of bidirectional tunnel between the MAG after switching, with the data cached soon MAG of access of node that is forwarded to that is detained in the mobile node switching process, to realize the seamless transmission of data flow.The main distinction of two kinds of handoff techniques is that the quick handoff technique of reactive is after mobile node is linked into new MAG, and is related with the MAG foundation before the switching again; And the quick handoff technique of predictive is the information that mobile node is about to switching that obtains before mobile node switches, and sets up in advance the association between two MAG.
The people such as Haisheng jiang have proposed " the interface handoff technique of multiple interface mobile node fault tolerant in the proxy mobile IPv 6 network ", this handoff technique has utilized the multiple interfaces of mobile node characteristic, other usable interface by mobile node, assist interface between MAG, to switch, main switching mode is, again pass the data buffer storage of the interface that switching back local mobile anchor (LMA), then by LMA data flow is redirected on other interface of this mobile node.
Generally speaking, the interface handoff technique among the relative RFC5213 of handoff technique that the people such as RFC 5949 " the quick handoff technique of proxy mobile IPv 6 " and Haisheng jiang propose has very large lifting in performance, but it has certain deficiency.For two kinds of handoff techniques among the RFC 5949, the data of transmitting in the mobile node interface switching process need to be at the enterprising row cache of MAG, this has increased the requirement to the storage capacity of MAG, when in the MAG coverage, having a plurality of mobile nodes to switch simultaneously, may cause the phenomenons such as loss of data that cause not because of the MAG storage capacity, because data need first buffer memory to transmit again, data transfer postpones also will greatly increase simultaneously, and this uses the transport latency sensitive class is fatal.Although the fault-tolerant multiple interface mobile node interface handoff technique of support that the people such as Haisheng jiang propose has utilized the characteristic of a plurality of interfaces of mobile node to assist data transfer in the interface switching process, but be forwarded to LMA by the data pack buffer that will mail to switching interface, then in the mode that is redirected to other interface of mobile node, two kinds of technology among ineffective solution RFC 5949 are to the too high problem of MAG buffer memory Capability Requirement, further, data are forwarded to first LMA, and then the data retransmission mode that is forwarded to other interface of mobile node may cause larger delay.
