S309: current MCC management packets, by the two PCIe passage corresponding with the VLAN of current MCC management packets, is sent to field programmable gate array by management crosspoint; Field programmable gate array is, after current MCC management packets increases inner VLAN ID label, current MCC management packets is forwarded to operation exchange unit;
S310: after the inner VLAN ID label of the current MCC management packets of operation exchange element deletion, according to the corresponding network port of the content choice of MCC management packets, MCC management packets is passed to the website equipment of below by operation exchange unit by current network port;
S311: the MCC management packets that in network port identification, a site apparatus transmits; The network port rule decided at the higher level but not officially announced according to VLAN is, after current MCC management packets increases inner VLAN ID label, current MCC management packets is sent to field programmable gate array;
S312: field programmable gate array identification after deleting the inner VLAN ID label of current MCC management packets, current MCC management packets is sent to management crosspoint, and management crosspoint determines the source of MCC management packets according to the outside VLAN ID of current MCC management packets;
S313: MCC management packets is sent to management crosspoint by Fast Ethernet passage by central processing unit; Management crosspoint is by the Fast Ethernet passage corresponding with the VLAN of current management data bag, and current management data bag is sent to management interface by administrative unit, and current management data bag is sent to computer by management interface, terminates.
10. data protocol retransmission method in ip ran as claimed in claim 6, it is characterized in that, step S4 comprises the following steps:
S401: the SCC signaling data bag of band VLAN is sent to signaling interface by central processing unit, and current SCC signaling data bag is transferred to control unit by signaling interface; Current SCC signaling data bag, by high speed gigabit Ethernet passage, is sent to management crosspoint by control unit;
S402: current SCC signaling data bag, by the Fast Ethernet passage corresponding with the VLAN of current SCC signaling data bag, is sent to field programmable gate array by management crosspoint; After field programmable gate array deletes the inner VLAN ID label of current SCC signaling data bag, by current SCC signaling data Packet forwarding to operation exchange unit; Operation exchange unit directly carries out the forwarding of route to SCC signaling data bag and business packet, terminate.
