Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not
For limiting the present invention.
A kind of method for supporting PON system port isolation of the present invention, core concept is: port isolation passes through creation
Port isolation group realizes that port isolation group includes two kinds of roles: master port and from port, port isolation group master port with
It is mutually isolated from port；Then with no restrictions from the relationship between port.
Fig. 1 is the default configuration of passive optical network PON system, and PON system includes n first line of a couplet port and n PON mouthfuls, is write from memory
Recognize under configuration, is intercommunication between n first line of a couplet port, is mutually isolated between n PON mouthfuls, between first line of a couplet port and PON mouthfuls
It is then intercommunication.
Fig. 2 is the functional schematic of middle port of embodiment of the present invention isolation group, and in this embodiment, port isolation group includes
Master port and from port, port isolation group has and only one master port, but may include one or more from port, master port
Either PON mouthfuls, it is also possible to first line of a couplet port with from port；Master port in port isolation group is mutually isolated with from port；
Then with no restrictions from the relationship between port, from being that isolation or intercommunication have followed system default configuration or system between port
Some other configurations values, are not controlled by port isolation group.
PON system can support multiple port isolation groups, PON system GEPON, 10GEPON, GPON, XGPON system simultaneously
One of.
When a port isolation group is configured with master port and after from port, master port is mutually isolated with from port, i.e. main side
Mouth is also isolated with master port from port with from port isolation, creates another port isolation group no longer to configure from port and master
Port isolation.
Fig. 3 is the example of middle port of embodiment of the present invention isolation group.In this embodiment, the master port of port isolation group is
First line of a couplet port GE8 is PON1, PON2, first line of a couplet port GE1 and first line of a couplet port GE2 from port.
The effect that port isolation group reaches is: master port is mutually isolated with from port, i.e. GE8 and PON1 is mutually isolated, GE8
It is mutually isolated with PON2, GE8 is mutually isolated with GE1, and GE8 is mutually isolated with GE2.
From being that isolation or intercommunication follow system default configuration between port, defaults between PON mouthfuls and be mutually isolated, because
This PON1 and PON2 is mutually isolated；It is intercommunication between first line of a couplet port, therefore GE1 and GE2 intercommunication；First line of a couplet port and PON mouth
Between be intercommunication, therefore PON1 and GE1 intercommunication, PON1 and GE2 intercommunication, PON2 and GE1 intercommunication, PON2 and GE2 intercommunication.
The usage scenario example that Fig. 4 is applicable in for the present invention.There are two OLT, respectively OLT1, OLT2；OLT1 connects
Three servers, respectively server 1, server 2, server 3, support three kinds of business.OLT2, can not because of resource constraint
Server is connected, the first line of a couplet port GE8 of OLT1 can only be cascaded to be connected to server, but need to only support the business of server 3.Cause
This, needs for GE8 to be isolated with GE1 and GE2；It is connected to ONU1 and ONU2 respectively under the PON1 and PON2 of OLT1, to avoid business mutual
It disturbs, also needs for GE8 to be isolated with PON1 and PON2.OLT2 need to be connected to server 3 by GE8, therefore GE8 cannot be isolated with GE3.
According to the above demand, a port isolation group can be configured on OLT1, the master port of port isolation group is GE8, from
Port is GE1, GE2, PON1, PON2.In this way, OLT1 can connect server 1, server 2 and server 3；OLT2 passes through OLT1
First line of a couplet port GE8 be connected to server 3；And the business of OLT1 and OLT2 is not interfere with each other.
