Hi,
GPON series products include the OLTs at the central office and the ONUs at the user side. Through the GPON access, the services such as the VoIP, Internet, VOD, IPTV, CATV, and E1 private line services can be provided concurrently over a single optical fiber. The services like VoIP require the real-time performance, which imposes high requirements on the delay of the packet transmission. If the delay of the packet transmission is too long, the VoIP service is unacceptable to the users. Comparatively, email and FTP services are delay-insensitive. To support voice, video, and data services that have different service requirements, the GPON system must be able to differentiate communication types and provide relevant services accordingly. By adopting the quality of service (QoS) technology, the GPON system can solve such problems to the full extent, thus improving the satisfaction of the user perception.
Triple play is a service provisioning mode in which integrated services can be provided to a user. Currently, the prevailing triple play application is the integrated high-speed Internet service, VoIP service, and IPTV service.
Configuring the VoIP ServiceStep 1: Create a VLAN.For example: MA5600T(config)#vlan 1001 smartStep 2: Add an upstream port.For example: MA5600T(config)#port vlan 1001 0/20 0Step 3: Configure a traffic profile.For example: MA5600T(config)#traffic table ip index 11 cir 512 priority 6 priority-policy local-SettingMA5600T(config)#traffic table ip index 12 cir 512 user-cos 6 priority-policy tag-in-packageNote: The voice service requires stable symmetrical upstream and downstream rates and high priority.Step 4: Configure a DBA profile.For example: MA5600T(config)#dba-profile add profile-id 11 type1 fix 512Step 5: Bind the DBA profile.For example: MA5600T(config-if-gpon-0/2)#tcont bind-profile 0 0 2 profile-id 11Note: Bind a fixed bandwidth of 512 kbit/s to VoIP T-CONT 2.Step 6: Specify VLANs for ONT ports.For example: MA5600T(config-if-gpon-0/2)#ont port vlan 0 0 iphost 101MA5600T(config-if-gpon-0/2)#ont port native-vlan 0 0 iphost vlan 101Step 7: Add a GEM port.For example: MA5600T(config-if-gpon-0/2)#gemport add 0 gemportid 151 eth encrypt onStep 8: Bind the GEM port to the ONT T-CONT.For example: MA5600T(config-if-gpon-0/2)#ont gemport bind 0 0 151 2 gemport-car 512 512Step 9: Create a mapping between the GEM port and the traffic stream.For example: MA5600T(config-if-gpon-0/2)#ont gemport mapping 0 0 151 vlan 101Step 10: Add a service port.For example: MA5600T(config)#service-port vlan 1001 gpon 0/2/0 gemport 151 multi-service user-vlan 101 rx-cttr 12 tx-cttr 11Step 11: Configure an ONT.Note: Currently, two software versions of the HG850 support MGCP and SIP respectively (V100R001C02B028 supports SIP and V100R001C02B031 supports MGCP). Select the configuration according to the actual environment.For example: MA5600T(config)#interface vlanif 1001MA5600T(config-if-vlanif1001)#ip address 192.168.100.100 255.255.255.0telnet 192.168.100.1 Default user name/password: root/adminNote: Configure the L3 interface address for VLAN 1001 to be in the same subnet of the default management address of the HG850.MGCP: TERMINAL>enable TERMINAL#configure terminal TERMINAL(config)#ipaddress static 190.1.1.201 255.255.255.0 190.1.1.1 TERMINAL(config)#mgcp mg-domain-name iad-2.comTERMINAL(config)#mgcp mg-port 2427TERMINAL(config)#mgcp mgc 1 address 190.1.1.1 port 2727TERMINAL(config)#mgcp user 0 1 aaln 0Note: The first "0" indicates "user start endpoint number", and the second "1" indicates "user end endpoint number", corresponding to two POTS ports of the HG850. Here, two VoIP users are added. The actual project is configured according to the service provisioning principles.SIP:TERMINAL(config)#ip address static 190.1.1.201 255.255.255.0 190.1.1.1 TERMINAL(config)#sip server 2 address 190.1.1.1 port 5060Note: Configure the IP address of the server to 190.1.1.1 and the port ID to 2727.TERMINAL(config)#sip user 0 id 88889999 password abcxyz name JackNote: Configure the SIP user ID of port 0 to 88889999, authentication password to abcxyz, and user name to Jack.Step 12: Save the data. huawei(config)#saveRemarks: For the QoS traffic classification, the principle of single T-CONT/single GEM port for single service is adopted in this case. According to the VLAN ID mapping mode, different services can be mapped to different GEM ports based on the VLAN IDs contained in the packets, thus implementing the rate limitation and scheduling based on the traffic stream.The rate limitation and priority strategy are implemented on the device near the source of the traffic. Therefore, in this case, the rate of the upstream traffic is limited by the gemport-car on the ONT, and the rate of the downstream traffic is limited by the limitation on the account performed by the BRAS. If no BRAS exists, the rate is controlled by the traffic table.For the priority strategy, it is recommended that you use the method in this case. That is, with the traffic table, the priority of the upstream traffic is re-marked, and the priority of the downstream traffic adopts the CoS copy. In this case, the queue strategy and queue depth require no modification. The scheduling strategy adopts PQ+WRR. After the scheduling strategy is configured, the configuration takes effect on the GPBC board and the SCUL control board of the OLT.
