Description
Technical field
The present invention relates to (the Gigabit-CapablePassive Optical Network of gigabit passive optical network in the communications field, be called for short GPON) technology, particularly, the method and system that relate to GPON system medium access control (Media Access Control is called for short MAC) address filtering configuration.
Background technology
GPON is the light access technology of a kind of point to multiple spot, and the network architecture that GPON inserts as shown in Figure 1.Wherein, optical line terminal (Optical Line Terminal is called for short OLT) is the GPON local side apparatus; Optical Network Terminal (Optical Network Terminal is called for short ONT) or optical network unit (Optical Network Unit is called for short ONU) are ustomer premises access equipment; Be connected by the light distributed network of forming by the passive optical splitters part (OpticalDistribution Network is called for short ODN) between OLT and the ONU; ONT management control channel (OMCC) provides management and the control channel of OLT to ONU.
G.984 series is the standard of formulating at GPON, wherein G.984.4 specifically defined ONT management control interface (ONT Management Control Interface, be called for short OMCI) general mechanism of standard and relevant management entity (Management Entity, be called for short ME) etc., OLT is configured relevant ME by OMCI, thereby realize Remote configuration and the management of ONU, wherein, solid line is a service channel among Fig. 1, dotted line is an OMCI management control channel, and the OLT left side is SNI (Service Node Interface is called for short SNI), the ONU right side is User Network Interface (User Network Interface is called for short UNI).
Fig. 2 (a) is a GPON uplink traffic transmission schematic diagram in the prior art, shown in Fig. 2 (a), uplink service adopts time-multiplexed form, and OLT distributes specific timeslice for the ONU uplink service, synchronization only allows specific ONU to send uplink service, avoids bumping; Fig. 2 (b) is a GPON downlink traffic transmission schematic diagram in the prior art, shown in Fig. 2 (b), the form of the descending employing broadcasting of GPON, downlink business identifies by different port-mark (PortId), PortId under same OLT is unique, and each ONU receives one's own data;
The GPON business data transmission is divided into clean culture and multicast, the GPON system is exactly the system of descending point-to-multipoint, and descending multicast service adopts unified PortId sign, the shared multicast PortId of the ONU under the same OLT, as shown in Figure 3, x is the PortId sign that descending multicast service uses.The fail safe of GPON downlink business can guarantee by mechanism such as cipher key change; Because the distinctive network topology architecture of GPON, uplink service can not be stolen usually.But still exist the disabled user to disturb the problem of network operate as normal, for example in user side access server, illegal adding and receiving multicast business etc. privately.
With the multicast service is example, and as shown in Figure 3, ONU goes up GPON MAC with whole receiving multicast datas usually, transmits in the Ethernet switching chip of ONU inside.For avoiding the inundation of multicast in Ethernet switching chip, need on exchange chip, enable the IP multicast management protocol and intercept (Internet Protocol Internet Group Management Protocolsnooping, be called for short IGMP snooping), control the forwarding of multicast.Flux of multicast is only transmitted to the port that adds multicast group.
But so still can not stop disabled user's receiving group flow, as shown in Figure 3, suppose that OLT is just sending the descending multicast service of multicast group G1, at this moment IGMP of ONU user A transmission joins message (illegally adding bag as G1 among Fig. 3), the multicast group G1 that adds lack of competence, the last IP multicast management protocol of ONU listens to this and joins message, and will be transmitted to user A to flux of multicast.
Because each multicast service all has a definite MAC Address, the manufacture-illegal method user of exceeding receives certain multicast group business, can realize by the mac address filter of configuration ethernet user port.G.984.4 Ding Yi MAC bridge port filter table (MAC bridge portfilter table data) management entity can be used to the mac address filter by the OMCI configurating subscriber port, defined data relationship in the MAC bridge port filter table management entity of the prior art, the management entity sign, and MAC filter table, the MAC filter table has been listed the target MAC (Media Access Control) address relevant with bridge port and has been had the information such as sign transmitted of whether allowing, and each in the MAC filter table filtered clauses and subclauses and comprised filtering rod purpose entry number (or filtering rod purpose index), filter byte and (comprise filtration/forwarding, interpolation/deletion equipotential information), and MAC Address.
Between MAC bridge port filter table management entity example and MAC bridge port configuration management entity (the MAC bridge port configuration data ME) example is one to one, and ONU can automatic establishment have the MAC bridge port filter table management entity example that identical ME identifies with it when creating MAC bridge port configuration management entity instance.MAC bridge port configuration management entity instance has one and points to physical channel destination node Ethernet UNI (Physicalpath termination point Ethernet UNI, be corresponding ethernet user's port) pointer of ME, be associated with ethernet user's port.Three's incidence relation as shown in Figure 4.
OLT is configured MAC bridge port filter table management entity by OMCI, can realize the mac address filter of ethernet user's port.For example, the attribute of MAC bridge port filter table ME example is set for the MAC bridge port related with ether user port 1, MAC bridge port filter table clauses and subclauses: entry number is 1, (be set to filter, add clauses and subclauses), MAC Address are 01:00:5e:01:01:01 to filter byte.
After MAC bridge port filter table management entity example is created, though the last IP multicast management protocol of ONU is intercepted still can be with multicast forwarding to the user port 1 that adds multicast group, but configuration: filter and be set to filtration in the byte according to MAC bridge port filter table management entity, do not transmit, therefore, descending target MAC (Media Access Control) address is the ethernet frame of 01:00:5e:01:01:01, to can not be forwarded to ether user port 1, the authority of ether user port 1 this multicast group business of reception that this has filtered configurable limit.
The definition of MAC bridge port filter table management entity is from the mac address filter of the Ethernet service of MAC bridge port striking out in the prior art, the user is received professional authority to be controlled, but the business datum that can't limited subscriber sends, the user still can arbitrarily send the request that adds certain multicast group, ONU still can be it as a multicast member, thereby to user's forwarding multicasting flow of illegal adding multicast group.Therefore, in fact MAC bridge port filter table management entity does not control user right fully, and reliability and fail safe are lower.
