An element in the set of interfaces domain of item E6, then checks forwarding table, and title thresholding is selected to be equal to the request message received
Title forwarding-table item E7, then select eligible 3 interface z8, forward the request message that receives from interface z8, hold
Row step 305;
Condition 3: the interface is both in the set of interfaces of the element and forwarding-table item E7 in the set of interfaces of interface entry E6
Element;
Step 310: if data C2 cannot be provided from the mobile node that interface z6 receives the request message, abandoning the request
Message, otherwise, the mobile node create a response message, and the message format of the response message is 1, title thresholding and data block
ID set thresholding is respectively the title thresholding and data block ID set thresholding of the request message received, type of message 3, load
The data block set defined for each data block ID in data block ID set;Then the response message is sent from interface z6;
Step 311: if mobile node U1 is known as interface z8 from the interface of oneself to response message, by the interface, then holding
Row step 313, it is no to then follow the steps 312;
Step 312: the infrastructure equipment being connected with the mobile node or infrastructure equipment link for forwarding the response message
From the interface of oneself to response message, which is known as interface z9, then checks convergence table, selects all title thresholdings
Equal to the convergence list item of the title thresholding of the response message, for the convergence list item of each selection, under infrastructure equipment executes
State operation: if the data block ID intersection of sets collection S2 of the data block ID set of the convergence list item and the response message received is not
For sky, then infrastructure equipment constructs a response message, and the message format of the response message is 1, and title thresholding is the convergence
The title thresholding of list item, data block ID collection are combined into the data of data block the ID set and the response message received of the convergence list item
Block ID intersection of sets collection S2, type of message 3 load the data block set defined for each data block ID in intersection S2,
Then the response message of building is sent from the interface domain of the convergence list item, infrastructure equipment is simultaneously from the data of the convergence list item
Intersection S2 is deleted in block ID set to delete the convergence list item if the data block ID collection of the convergence list item is combined into sky, execute step
Rapid 311;
Step 313: the mobile node U1 for receiving response message from interface z8, which checks required list and deletes title thresholding, is equal to this
Title thresholding and data block the ID set of response message are equal to the request list item that the data block ID of the response message gathers, if moved
It is equal to the request list item of the title thresholding of the response message in the required list of dynamic node U1 there is no title thresholding, thens follow the steps
314, it is no to then follow the steps 311;
Step 314: all data blocks received are built into data C2 by mobile node U1;
Step 315: terminating;
In step 310, if being capable of providing data C2, and the movable joint from the mobile node that interface z6 receives the request message
Interface z6's point fails before sending the response message, which then selects the interface x3 for being in effective working condition,
A response message is constructed, sends the response message from interface x3, step 311-315 is executed and completes to obtain data procedures.
4. a kind of new generation network implementation method based on multipath according to claim 3, which is characterized in that in movement
Node U1 has N number of interface, interface f supported protocol pfAnd the supported protocol p with infrastructure equipment I2fInterface link be connected, 1
Under conditions of≤f≤N, if mobile node U1 detects that interface f1 fails, 1≤f1≤N then executes following handoff procedures:
Step 401: starting;
Step 402: mobile node U1 checks required list, selects interface thresholding to be equal to all request list items of interface f1, for every
A request list item, mobile node U1 execute operations described below: mobile node U1 selects eligible 4 interface f2, by the required list
The interface thresholding of item is updated to interface f2, constructs a handover request, and the message format of the handover request is 0, and entitled sky disappears
Ceasing type is 4, loads as the request list item, then sends the request message from interface f2;
Condition 4: in the total interface of mobile node U1, the request list item number of the set of interfaces thresholding comprising interface f2 is most
It is small;
Step 403: after infrastructure equipment I2 receives handover request from interface f3, check convergence table, select title thresholding and
Data block ID set thresholding is equal to the title thresholding and data block ID set of the request list item in the handover request load received
Convergence list item, the interface thresholding of the convergence list item is then updated to interface f3;
Step 404: terminating.
