Limit.Because number of network users is very big, core layer uses multiple stage BRAS to realize load balancing, by two layers of ring between BRAS equipment
Net connection.SW A transmits the data traffic of user A by VLAN 10, and BRAS A is pooled VLAN by Super VLAN
100, the information such as the record IP address of user A and MAC Address, and realize certification and mandate, now this is had no perception by BRAS B.
After user A migrates, being connected on AP B, the data vlan of this user becomes 20, by the looped network of core layer, the stream of user A
Amount is eventually returned to BRAS A, Super VLAN pool VLAN 100, thus realize this flow without re-authentication forwarding.
Because core layer BRAS equipment constitutes two layers of looped network, all users are at a broadcast domain, for separate unit BRAS
For equipment, need to learn the ARP request message sent when the MAC Address list item of all users, such as user B are reached the standard grade, at core
Flood in central layer forwarding, and BRAS A and BRAS B can learn the MAC Address to user B.When number of users reaches hundreds of thousands level
Not, after exceeding BRAS equipment mac address table specification capacity, the MAC Address having a large number of users cannot be learned to, and causes this type of
Customer flow all forwards in the way of flooding, and causes network paralysis under serious conditions.
In order to avoid prior art defect, the present invention passes through broadcast domain isolation technology, stops broadcasting packet and two layers of the unknown
Flooding of unicast message, only allows the forwarding of unicast message.The ARP request message sent when user B reaches the standard grade is straight by BRAS B
Connecing absorption, therefore miscellaneous equipment in double layer network, such as BRAS A will not receive this ARP request message, also avoids the need for study
The MAC Address of user B, thus solve that core layer equipment needs to learn all user's MAC address and the mac address table that causes holds
Problem that amount is not enough.
After user A migrates, surf the Net owing to connecting BRAS A by AP A before migrating, connected by AP B after migration
BRAS B surfs the Net.Owing to BRAS B does not has the Certificate Authority information of the user A in BRAS A, the ARP request message that user A sends
Cannot be broadcast to BRAS A, therefore the flow of user A must be forwarded by BRAS A and could realize forwarding without re-authentication.At this
In invention, when user A reaches the standard grade from BRAS A certification, BRAS A can be by the MAC ground of the MAC Address of this user A with this BRAS A
The corresponding relation of location is sent to BRAS B.The gateway of user A is the IP address of BRAS A, and after migration, gateway address keeps constant.
After BRAS B receives the ARP request message of the user A after migration, obtain the source MAC in this message, then search in this locality
The MAC Address of the BRAS A that this source MAC is corresponding.Then by ARP proxy technology, using the MAC Address of BRAS A as response report
The source MAC of literary composition replies to user A, and after completing above-mentioned ARP message interaction, follow-up flow purpose MAC of user A is all BRAS
The MAC Address of A, can be delivered on BRAS A by bis-layers of unicast forwarding of BRAS B, thus the nothing realizing user's A flow is recognized again
Card forwards.
