Description
Technical field
The present invention relates to networking technology area, relate in particular to a kind of lisp (Location/ID Separation Protocol, identity and position separated protocol)-control method for movement and Lisp-MN and the mobile node of MN (Motion Node, mobile node).
Background technology
The size of DFZ (Default Free Zone, acquiescence free zone) routing table increases with the speed that increases gradually, and it has damaged the extensibility of route and the execution of route assemblage.The route scalability problem has caused industry and the very large interest of academia.
IAB (Internet Architecture Board, Internet Architecture Board) member discusses and thinks that underlying causes that the DFZ routing table increases is that the dual semanteme of IP address causes, and identifier is not only done but also do the position in the IP address in existing network.
Present IRTF RRG (Internet Research Task Force Routing Research Group, study Internet task groups route working group) is devoted to develop new route and the address framework is supported many caves property, traffic engineering and mobility.
Lisp is a new routing architecture framework that according to RRG the demand of route and address research is proposed with headed by the Cisco System Co., by current IP address being separated into terminal iidentification (EIDs, End-identifiers) and route position (RLOCs, Routing Locators) alleviates the size of DFZ routing table, increased expansion and reduced overall visible, route prefix number.
The network configuration of Lisp as shown in Figure 1.The basic thought of LISP is to encapsulate one deck IP heading in IP layer outside again, and the route that produces for the increase that reduces the edge network user keeps the stable of backbone network (BGP) routing table to the impact of backbone network routing table.Lisp is divided into terminal iidentification (EID) and route position (RLOC) with existing IP address system, and introduced the concept of tunnel router (" Tunnel Routers "), tunnel router is divided into entrance tunnel router (Ingress Tunnel Router, ITR) and exit tunnel router (Egress Tunnel Router, ETR).ITR and ETR all need to register the binding of EID and RLOC in mapping server (Map-Server, MS).Concerning the main frame of ETR side, ETR is responsible for registering EID and the RLOC binding of this main frame, and ITR is responsible for the binding of the EID/RLOC of buffer memory ETR side main frame.Concerning ITR side main frame, ITR registers the binding of EID and the RLOC of this main frame equally.In addition, ITR is responsible for the encapsulation of data and searching of mapping among the Lisp, according to RLOC information corresponding to purpose EID information searching.ETR is responsible for carrying out the decapsulation of data message among the Lisp.
The original intention that the LISP agreement proposes is the scale that solves routing table, can not solve the mobility of network, and along with the development of network, the mobility of network is necessary, and the demand of Lisp design must solve mobility, many caves property.
Lisp-MN is a kind of mobility solution of Lisp.Lisp-MN is to be lisp-MN with the node definition in the lisp network, and lisp-MN is different from common MN, and lisp-MN has the function of ETR/ITR, and Fig. 2 is based on the schematic network structure of Lisp-MN.When lisp-MN moved to other networks, lisp-MN registered the mapping of its EID/RLOC to its MS.
At the communication process of lisp network, if when lisp-MN moves to reposition A from position A, when the downlink data of this lisp-MN sent, Correspondent Node sends to the packet of lisp-MN can lose or exist delay.
Summary of the invention
