S106. according to ip, source, the source mac of ARP request message or ARP reply message, outer vlan, internal layer vlan, port, upgrade arp entry in ARP table, and the main frame route entry of upgrading exchange chip, S107 entered;
S107. upgrade arp entry timing, because ARP reply message does not need counting, so zero clearing sends ARP request message entry number counting, end.
Concerning ARP table, if do not carry out arp entry timeout treatment, ARP table can infinitely increase, and corresponding exchange chip main frame routing table also can infinitely increase.Therefore carrying out ARP table while safeguarding, not online ip terminal is deleted to corresponding arp entry.Because CPU disposal ability is limited, while adopting each timing to travel through arp entry, the arp entry of some is sent to ARP request message request, see whether ip terminal is also online.The alarm of ip address conflict, when there is no ip address conflict, be eliminated the alarm of ip address conflict.Therefore adopt and every a period of time, enable timer and carry out timeout treatment.Timeout treatment is divided two functions, and one is the timeout treatment of ip address conflict, and another is the timeout treatment of arp entry.
As shown in Figure 7, for ip address conflict is overtime and the overtime treatment mechanism of arp entry, concrete handling process is as follows:
C101. travel through successively three layer interfaces of OLT, by there being three layer interface ip addresses of ip address conflict alarm, be labeled as and there is no ip address conflict; The ip address of ip address conflict alarm is sent to ARP request message simultaneously.Object is to see that the ip equipment whether connecting also exists same ip address, and source ip, the object ip of ARP request message is the ip address that has the alarm of ip address conflict.
C102. judge whether three layer interfaces have traveled through, and if not, enter C101, continue traversal three layer interfaces; If so, enter C103, carry out the processing of arp entry timeout mechanism.
C103. travel through successively the entry in ARP table, the entry in ARP table is divided into multistage and travels through.
C104. judge whether all arp entrys in ARP table have traveled through, if enter C115, process, and enter if not C105 and process.
Whether the arp entry that C105. judgement will travel through traveled through, and if so, entered C103; If not, enter C106.
The arp entry that C106. will travel through is designated as and travels through, and the counting of traversal arp entry adds 1.
Whether the timing of the arp entry that C107. judgement is traveling through is overtime, if so, enters C108 and processes; If not, enter C103 and continue the next arp entry of traversal.
C108. after judging that this arp entry is overtime, whether sent three ARP request messages and asked the corresponding mac of ip address, if so, entered C109 and process, entered if not C113 and process
C109. judge whether arp entry is double-deck vlan, if so, enter C110 and process; If not, entering C112 processes.
C110. judge whether to exist the double-deck vlan of other arp entrys and this arp entry to identical, if so, enter C112 and process; If not, entering C111 processes.
C111. from tri-layer of three layer interface table of exchange chip vlan, delete double-deck vlan tri-layer interfaces, keep not having arp entry to use this three layer interfaces entry, just from exchange chip, delete; And delete double-deck vlan tri-layer interfaces from three layers of vlan interface table of exchange chip.
C112. from exchange chip, delete the main frame route of this arp entry; From ARP table, delete this arp entry, enter C103;
C113., after overtime to arp entry, what do not send three ARP request messages continues to send request message, the corresponding mac of request ip address; The message number counting that sends request of arp entry adds 1, identifies this overtime arp entry and has sent how many ARP request message numbers.
C114. judge in this Timing Processing, ARP request message sends the normal process ability whether number surpasses cpu, if so, enters C115; If not, enter C103;
C115. whether the counting of judgement traversal arp entry number is more than or equal to all entry number in ARP table, if so, enters C116; If not, enter C117;

C117. finish this timing and process, wait for timing processing next time.
As shown in Figure 1, by specific embodiment, describe in detail between main frame and ip bearer network and between host A and host B, be intercommunication how.Suppose that host A is configured to outer vlan1000, internal layer vlan10, host B is configured to outer vlan1000, internal layer vlan20.When host A is communicated by letter with host B, send ARP request message, the mac address of requesting host B, OLT acquires the mac of host A, outer vlan1000, internal layer vlan10, in exchange chip three layer interface tables, create double-deck vlan tri-layer interfaces, dose the route entry of host A to exchange chip.OLT replys ARP reply message to the ARP request message of host A, the ip address that in ARP reply message content, ip address, source is host B, and source mac is OLT main control unit mac.Host B sends the mac address of ARP request message request host A, OLT learns the mac of host B, outer vlan1000, internal layer vlan20, in three layers of vlan interface table of exchange chip, create double-deck vlan tri-layer interfaces, add main frame route B to exchange chip.OLT replys to the ARP request message of host B the ip address that ARP reply message source ip address is host A, and source mac is OLT main control unit mac.The mac that host B has been learnt host A is like this on main control unit, and the data flow object mac that host B sends to host A is main control unit.Main control unit receives that the object ip address that host B is sent is the data flow of host A ip address, and through the route of exchange chip, data flow object mac is replaced by the mac of host A, and internal layer vlan is replaced by 10 and is forwarded to host A; The data flow that host A is come is replaced to the mac of host B by main control unit exchange chip, internal layer vlan replaces to 20 and is forwarded to host B; Between host A and host B, double-deck vlan data flow can intercommunication like this.The intercommunication of host A and ip bearer network, upstream is forwarded to ip bearer network through gateway 20.1.1.254, the data flow of getting off from ip bearer network, forwarding through OLT main control unit exchange chip, changing object mac into is host A, outer vlan1000, and the forwarding data flow of internal layer vlan10 is to host A.
Shown in Fig. 2, by specific embodiment, describe in detail between ONU and voice bearer net and between ONU1 and ONU2, be intercommunication how.For example the outer vlan of ONU1 is 1000, internal layer vlan is 10, ip is 20.1.1.53, gateway is 20.1.1.254, and the outer vlan of ONU2 is 1000, and internal layer vlan is 20, ip is 20.1.1.55, gateway is 20.1.1.254, and OLT joins the supervlan that a subvlan is 1000, and vlan1000 is all joined in the joint side of ONU side and OLT.Between ONU and voice bearer net, communicate by letter, OLT is as two-layer equipment, and data message directly for example, carries out intercommunication between ONU and gateway (20.1.1.254), does not use the ARP module of OLT.Intercommunication between ONU1 and ONU2, ONU1 sends the ip address of ARP request message request ONU2, OLT receives ARP request message, add outer vlan and internal layer vlan in three layers of vlan interface table in exchange chip, interpolation ip is 20.1.1.53, the mac that mac is ONU, and outer vlan is 1000, internal layer vlan is that 10, port receives that OLT receives that the main frame route entry of ARP request message port numbers arrives exchange chip.Receive after the ARP request of ONU1 request ONU2, OLT transmission source ip is the ip of OLT supervlan, source mac is ARP request message request ONU2ip mac corresponding to address of OLT supervlan mac, ONU2 sends ARP reply message and replys ARP request message, and OLT has acquired the ip(20.1.1.55 of ONU2 like this), the arp entry of mac, outer vlan1000, internal layer vlan20, port add in exchange chip and (comprise and add double-deck vlan tri-layer interfaces and interpolation main frame route).OLT carries out ARP proxy to ONU1 request mac corresponding to ONU2ip address, transmission source ip is the ip of ONU2, source mac is the ARP reply message of the mac of OLT supervlan, mac corresponding to ip that ONU1 acquires ONU2 is the mac of OLT supervlan, ONU1 sends to OLT to the ip stream of ONU2 like this, through tri-layers of routing forwarding of OLT, arrives ONU2.ONU2 replys the ip stream of ONU1, sends the mac of ARP request message request ONU1, and OLT carries out ARP proxy, transmission source ip is the ip of ONU1, source mac is the ARP reply message of OLT supervlan mac, and ONU2 acquires the mac that ONU1ip is corresponding, is also the mac of OLT supervlan.The ip stream packet that ONU2 replys ONU1ip stream also sends to OLT, through tri-layers of routing forwarding of OLT, sends to ONU1, and the voice ip stream of ONU1 and ONU2 can intercommunication like this.
As depicted in figs. 1 and 2, described host A is hung race business under the ONU of line card 1, be switched to the lower time of ONU of line card 2, the inbound port that OLT main control unit detects the ARP message of host A transmission changes, therefore the route entry of original host A has been deleted, again the host A route entry of new port is write in exchange chip, the business of host A and ip bearer network or main frame and voice bearer net can continue intercommunication like this.
The present invention is not limited to above-mentioned execution mode, for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, within these improvements and modifications are also considered as protection scope of the present invention.The content not being described in detail in this specification belongs to the known prior art of professional and technical personnel in the field.

C102. judge that whether three layer interfaces have traveled through, and if so, enter C103; If not, enter C101;
C103. travel through successively the arp entry in ARP table, the arp entry in ARP table is divided into multistage and travels through;
C104. judge that whether all arp entrys in ARP table have traveled through, and if so, enter C115; If not, enter C105;
Whether the arp entry that C105. judgement will travel through traveled through, and if so, entered C103; If not, enter C106;
The arp entry that C106. will travel through is designated as and travels through, and the counting of traversal arp entry adds 1;
Whether C107. judgement is traveling through the timing of arp entry overtime, if so, enters C108; If not, enter C103;
C108. after judging that this arp entry is overtime, whether sent request message three times, the corresponding mac of request ip address; If so, enter C109; If not, enter C113;
C109. judge that whether arp entry is double-deck vlan, if so, enters C110; If not, enter C112;
C110. judge whether to exist the double-deck vlan of other arp entrys and this arp entry to identical, if so, enter C112; If not, enter C111;
C111. from the three layer interface tables of exchange chip vlan, delete double-deck vlan tri-layer interfaces, and delete double-deck vlan tri-layer interfaces from three layers of vlan interface table of exchange chip.
C112. from exchange chip, delete the main frame route of this arp entry; From ARP table, delete this arp entry, enter C103;
C113., after overtime to arp entry, what do not send three request messages continues to send request message, the corresponding mac of request ip address; The message number counting that sends request of arp entry adds 1;
C114. judge in this Timing Processing, request message sends the normal process ability whether number surpasses cpu, if so, enters C115; If not, enter C103;
C115. whether the counting of judgement traversal arp entry number is more than or equal to all entry number in ARP table, if so, enters C116; If not, enter C117;
C116. the arp entry that travels through ARP table, empties and travels through sign, zero clearing traversal arp entry counting number, and this timing that is through with is processed, and waits for timing processing next time;
C117. finish this timing and process, wait for timing processing next time.
