Step S45, through step S44, lookup result has two kinds, has the Bundle corresponding with local terminal EPD in the Bundle information table, does not perhaps exist, thereby has two to select branch:
There is branch in Bundle:
Step S45-11 finds the Bundle corresponding with local terminal EPD, supposes that its name is called Bundle1;
Step S45-12 is tied to this ppp link among the Bundle1, thereby exists branch to accomplish the MLPPP dynamic binding process of ppp link at this.
There is not branch in Bundle:
Step S45-21 owing to do not find corresponding Bundle, therefore need create a Bundle for this link is new, supposes that the new Bundle name of creating is called BundleN.
Step S45-22 upgrades the Bundle information table, and the corresponding relation of this EPD and BundleN is updated in the table, after having the link LCP consistent with EPD to consult successfully, can walk to exist branch next time.
Step S45-23 is tied to this ppp link among the BundleN, thereby does not exist branch also to reach the MLPPP dynamic binding function of ppp link at this.
Step S45-24, owing to be a new Bundle who creates, this Bundle need carry out NCP to be consulted
More than after two branches accomplish, the step S46 of end:
Step S46, this finishes just to represent the end of MLPPP dynamic binding flow process, and follow-up flow process is consistent with the static MLPPP binding flow process that exists at present.
In sum; The present invention is on the basis of following the PPP/MLPPP agreement; Make full use of this option of Endpointdiscriminator, make its distinguishing mark that becomes Bundle, let the identical link auto-polymerization of all EPD together; Need not to bind carrying out static MLPPP in advance, thereby reached the dynamic binding function of MLPPP.
