Certain example embodiments, however, it is to be appreciated that may be realized in various forms the disclosure without the reality that should be illustrated here
The mode of applying is limited.On the contrary, these embodiments are provided so that the disclosure is more thorough and complete, and can be by this public affairs
The range opened completely is communicated to those skilled in the art.
Fig. 1 shows conventional access network system structure, the network equipment in legend in user network can directly or
Pass through various different modes, such as optical distribution network (0DN), xDSL, PON network, point-to-point fiber link or WiFi radio chains
Road etc. is linked into access node AN, accesses the wideband network gateway BNG in network system as a border router, is responsible for connecing
Enter network devices in system address configuration management, pass through the router solicitation RS between subscriber's main station and wideband network gateway BNG
With router advertisement RA messages, subscriber's main station is gathered around there are one global unicast address.
Two stages are included typically for an IPv6 shaftless drivings process：Link local address is matched
Put the configuration with global unicast address.When the network interface of a host equipment in user network enables, host equipment can be first
First according to local prefix FE80：：/ 64 and EUI-64 interface identifiers generate a link local address for the interface, if
Address conflict occurs in subsequent repeat to address (RA) conflict inspection (DAD), then must to the interface manual configuration link-local address,
Otherwise the interface will be unavailable.With reference to the address configuration flow chart under conventional access network system illustrated in Figure 2, in user network
Host equipment on global unicast address configuration step it is as follows：1. host equipment after link local address has been configured, is sent
Router solicitation RS messages ask the prefix information of router.After 2. BNG receives router advertisement RS messages, send unicast road
RA messages are noticed by device, carry the prefix information for shaftless driving.3. BNG also can periodically be sent simultaneously
Multicast router notices RA messages, carries the prefix information for shaftless driving.Later, host equipment receives road
After noticing RA messages by device, an interim global unicast address is generated according to prefix information and configuration information.Start simultaneously
DAD sends the uniqueness of NS authentication of message temporary address, and the address is in transitory state at this time, on user network link
After other network nodes receive the NS messages of DAD, if without user using the address, otherwise dropping packets generate response
The NA messages of NS.If host equipment does not receive the NA messages of DAD, illustrate address be it is globally unique, then with this provisionally
Location initialization interface, at this time address enter effective status.
As previously mentioned, under conventional access network system, host and BNG Switch Router request/routing in user network
Device notices (RS/RA) message direct transparent transmission access node, and this address configuration mode, which is accessed in SDN under the network architecture, to be existed
