•   Traffic is single-tagged with an S-Tag throughout the aggregation network
•   The S-tag may be common to more than one user port.
•   The ONU always add an S-VID or translate am incoming S-VID for upstream traffic.
•   In downstream the OLT will use MAC- address and priority bits to determine the proper
    downstream GEM port

• Translation of the VID value: C-VID is translated to S-VID in
  upstream and from S-VID to C-VID in downstream.
• Translation of the p-bit value: C_p-bit must be translated into
  S_p-bit in the upstream direction and S_p-bit into C_p-bit in the
  downstream direction.

 • The ONU maps 1:1 VLAN into a unique U interface.
 • For single tagged VLANs at V, the ONU add or translate a S-VID.
 • For double tagged VLANS at V, the ONU is provisioned to assign a C-VID or
   translate an incoming tag into C-VID, and the OLT adds the S-VID.

VLANs for Business Ethernet Services (VBES)

•   In a VLAN for Business Ethernet Services architecture, the traffic at the U interface can
    be untagged, tagged, double-tagged and priority tagged.

•   For Transparent LAN Service (TLS) the ONU has to add always an S-tag or translate
    an incoming S-tag into a new S-tag for upstream traffic.

•   Assignment of unique S-VLANs tags by the ONU for TLS:
       –   For single-tagged, priority-tagged or untagged, the ONU will add an S-tag in upstream
           traffic. For downstream the S-tag is removed at the ONU. Optional, non-TLS traffic can be
           identify by Q-tags.
       –   For double-tagged, the ONU will accept only valid S-tags (that could be translated), the
           others will be silently discarded. For downstream, the S-tag may be translated back before
           being forwarded to the U interface.

•   In the VBES picture:
       –   Subscriber 1: Uses Q-VID (100) for Internet access (non-TLS) in the 1:1 model; uses Q-VID
           (101) for Internet or ASP (non-TLS) in the N:1 model, Q-VID (x) is used for TLS traffic and
           S-VID (102) is added.
       –   Subscriber 2: Q-VID (101) as subscriber 1; Q-VID (x) for TLS, however it has 2 ports and
           the OLT will need to learn VLAN/MAC addresses.
       –   Subscriber 3: Double tagged port, frames with S-VID (105) are accepted.

                                                  TR-156 Monitoring features




•   VLAN Tagging check
•   VLAN filtering
•   Traffic prioritizing
•   TCONT-GEM port-Ethernet flow relationship
•   Efficient use of bandwidth resources
•   Multicast channel supervision as well as its associated
    control flows

How GPON Doctor validates TR-156?




•   GPON Doctor 8000 generates the TCONT+GEMport+VID+TC+PPTP association map
    based on the OMCI messages exchanged between the OLT and the ONUs.
•   GPON Doctor 8000 extracts the user traffic (already decrypted) belonging to an
    specific TCONT+GEM port to a protocol analyzer where it is verified its compliance
    with the VID+TC shown in the association map.

How GPON Doctor check resource usage?



•   GPON Doctor 8000 identifies the BWMaps and generates a real time bandwidth allocation map
    per ONU.
•   The information provided by the GPON Doctor allows to verify if the OLT is assigning bandwidth
    efficiently and according to the agreements with the Service providers.

GPON Doctor and Multicast traffic


•     Multicast traffic, consisting of a set of multicast groups and downstream IGMP messages, is
      forwarded using one or more N:1 VLANs.
•     The multicast-VLAN traffic required by all ONUs is transported within a Multicast GEM port.
•     The Multicast GEM port is unidirectional (downstream) and GPON AES encryption is disabled.
•     As Multicast GEM port is unidirectional, upstream control flows use existing bidirectional data
      GEM port with appropriate TC.

•     GPON Doctor 8000 functionality of TCONT+GEM port traffic extraction allows to monitor the
      Multicast GEM port simultaneously with its related control flows.
•     Multicast traffic can be extracted, downstream/upstream IGMP messages could be analyzed and,
      with the appropriate player, multicast content can even be viewed.

  • 13. VLANs for Business Ethernet Services (VBES) • In a VLAN for Business Ethernet Services architecture, the traffic at the U interface can be untagged, tagged, double-tagged and priority tagged. • For Transparent LAN Service (TLS) the ONU has to add always an S-tag or translate an incoming S-tag into a new S-tag for upstream traffic. • Assignment of unique S-VLANs tags by the ONU for TLS: – For single-tagged, priority-tagged or untagged, the ONU will add an S-tag in upstream traffic. For downstream the S-tag is removed at the ONU. Optional, non-TLS traffic can be identify by Q-tags. – For double-tagged, the ONU will accept only valid S-tags (that could be translated), the others will be silently discarded. For downstream, the S-tag may be translated back before being forwarded to the U interface. • In the VBES picture: – Subscriber 1: Uses Q-VID (100) for Internet access (non-TLS) in the 1:1 model; uses Q-VID (101) for Internet or ASP (non-TLS) in the N:1 model, Q-VID (x) is used for TLS traffic and S-VID (102) is added. – Subscriber 2: Q-VID (101) as subscriber 1; Q-VID (x) for TLS, however it has 2 ports and the OLT will need to learn VLAN/MAC addresses. – Subscriber 3: Double tagged port, frames with S-VID (105) are accepted. © 2009 TECNALIA - TELNET-RI

  • 16. How GPON Doctor validates TR-156? • GPON Doctor 8000 generates the TCONT+GEMport+VID+TC+PPTP association map based on the OMCI messages exchanged between the OLT and the ONUs. • GPON Doctor 8000 extracts the user traffic (already decrypted) belonging to an specific TCONT+GEM port to a protocol analyzer where it is verified its compliance with the VID+TC shown in the association map. © 2009 TECNALIA - TELNET-RI
  • 17. How GPON Doctor check resource usage? • GPON Doctor 8000 identifies the BWMaps and generates a real time bandwidth allocation map per ONU. • The information provided by the GPON Doctor allows to verify if the OLT is assigning bandwidth efficiently and according to the agreements with the Service providers. © 2009 TECNALIA - TELNET-RI
  • 18. GPON Doctor and Multicast traffic • Multicast traffic, consisting of a set of multicast groups and downstream IGMP messages, is forwarded using one or more N:1 VLANs. • The multicast-VLAN traffic required by all ONUs is transported within a Multicast GEM port. • The Multicast GEM port is unidirectional (downstream) and GPON AES encryption is disabled. • As Multicast GEM port is unidirectional, upstream control flows use existing bidirectional data GEM port with appropriate TC. • GPON Doctor 8000 functionality of TCONT+GEM port traffic extraction allows to monitor the Multicast GEM port simultaneously with its related control flows. • Multicast traffic can be extracted, downstream/upstream IGMP messages could be analyzed and, with the appropriate player, multicast content can even be viewed.
