Abstract
A technology is disclosed for reducing the burst of DAD messages which may be triggered due to the change of the network prefix when using the technique of the neighbor discovery proxy. According to this technology, in roaming from the access network linkto the access network link, MRreceives advertisement of a new prefixfrom AR. MRselects and informs, for example only MR, that it is necessary to change the prefix. Thus, MRand VMNconfigure new addresses, respectively. When address configuration is completed at the mobile network of MR, MRinforms another MRthat it is necessary to change the prefix, and then MRand VMNconfigure new addresses, respectively. This can prevent DAD messages generated along with the address configuration from flocking in a short period.
