Specific embodiment
Present embodiment is by PON+EOC, especially EPoC Opto-electronic system, when an optical port of OCU is corresponding
When multiple ports RF, i.e., when an OCU equipment connects multiple CDN, pass through multiple passive optical network media access controls on OCU
(PON MAC) and multiple ports RF correspond；Or a PON MAC on OCU corresponds to multiple ports RF, builds on OCU
The mapping relation information of vertical CNU and the port OCU.Downlink message is filtered by the mapping relation information, to make corresponding
Downlink message can reach corresponding CNU, complete the efficient forwarding of downlink message by the corresponding port RF, i.e. CDN.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Example 1:
As shown in figure 3, comprising a light-receiving sending module, a PON MAC in OCU, while multiple ports RF are corresponded to,
The CDN connection CNU connected by each port RF, the sending method of downlink message in the Opto-electronic system of present embodiment,
Include:
S301:CNU1 (purpose CNU), which is powered on, completes initialization procedure, and the control module of OCU passes through the initialization of CNU1
Journey establishes the mapping relation information of the LLID of CUN1 and the mark of the corresponding port RF in PON MAC；
In initialization procedure, OLT is that CNU1 distributes unique LLID.Since centre of the OCU1 between OLT and CNU1 is set
Standby, OCU1 can get the LLID (LLID1) of CNU1.
Meanwhile the related MPCP protocol interaction message in CNU1 initialization procedure reaches OCU1 by the specific port RF,
Therefore OCU1 will be seen that the corresponding port RF CNU1 by internal hardware mark, and then know the corresponding port RF LLID1
Identify RFID1.
OCU1 establishes LLID by the mark of the port RF passed through the LLID and the CNU1 message interaction of the CNU1 obtained
With the mapping relation information of the mark of the port RF, i.e. LLID1 corresponds to RFID1.
S302:OLT sends downlink message, has LLID1 in downlink message leading character；
The downlink message that S303:OLT is sent is received by the light-receiving sending module of OCU1 first, then via OCU1's
PON MAC processing, PON MAC search the mapping relation information of the LLID that control module is established and RFID, and it is corresponding to find LLID1
RFID1；
The message of corresponding LLID1 is sent to corresponding CNU1 by RF1 by S304:OCU1.
Complete the filtering repeating process of entire downlink message.
Embodiment 2:
As shown in figure 4, including a light-receiving sending module, multiple PON MAC and multiple ports RF, PON in OCU
MAC and the port RF correspond, the CDN connection CNU connected by each port RF, in the Opto-electronic system of present embodiment
The sending method of downlink message, comprising:
S401:CNU1, which is powered on, completes initialization procedure, and the control module of OCU is by the initialization procedure of CNU1 in PON
The mapping relation information of the mark of PON MAC1 and the mark of the port RF is established in MAC1；
In initialization procedure, OLT is that CNU1 distributes unique LLID.Since centre of the OCU1 between OLT and CNU1 is set
Standby, OCU1 can get the LLID (LLID1) of CNU1.
Since each PON MAC and the port RF are corresponded, it can guarantee the downlink message into PONMAC from hardware
Can only by the port RF corresponding with the PON MAC forward or uplink the message from some port RF can only via with this
The corresponding PON MAC in the port RF is handled, therefore only needs to carry out packet filtering by the LLID of CNU.LLID1 only can
It is obtained by PON MAC1.
S402:OLT sends downlink message, has LLID1 in downlink message leading character；
S403:OLT send downlink message first by OCU1 light-receiving sending module receive, then PON MAC1 according to
The mapping relation information of the mark for the LLID1 and PON MAC1 that control module is established is filtered, and PON MAC1 is determining downlink
When message belongs to itself received downlink message, downlink message is transmitted to by CDN1 by the port RF1 being connected.
Since PON MAC1 and RFID1 are corresponded on hardware, which is forwarded via RF1 into CDN1.
The downlink message of corresponding LLID1 is sent to corresponding CNU1 by RF1 by OCU1, and the filtering for completing entire downlink message is forwarded over
Journey.
