Configuring Your SmartRG™ - Common Use Cases
Use Case: Setting Up Wireless Distribution System (WDS)
When deployed in a larger home or office, a single wireless access point may not be able to provide adequate Wi-Fi coverage. Wireless Distribution Systems (WDS) provides a solution for this problem. WDS combines multiple gateways to act as a single larger wireless access point allowing Wi-Fi clients to seamlessly roam all access points plus it provides wired access to the entire network.
Two or more SmartRG gateways can be configured for WDS operation. The example below depicts a WDS deployment with three SmartRG gateways in a large home or office – one primary gateway in the center of the building and one remote gateway at either end of the building.

Configuring Your SmartRG™ - Common Use Cases
Use Case: Creating IPTV Service Configurations
The SR350N, SR350NE, SR500N and SR500NE SmartRG gateways are designed to meet the demands of IPTV service deployments.
Typically IPTV services have been deployed using bridged architectures with public IP addresses assigned to the IPTV Set-top-boxes (STBs) connected to the gateway’s LAN ports. A typical bridged IPTV service configuration is shown below.
Figure 25 Bridged IPTV Configuration
Recently service providers have begun deploying routed IPTV services with STBs being assigned private LAN IP addresses by the gateway. A typical routed IPTV service configuration is shown below.

SmartRG™ Residential Gateways
SmartRG gateways are designed to exceed the high bandwidth demands of either IPTV service architecture. Refer to the appropriate section below to configure the SmartRG gateway for your particular IPTV deployment architecture.
Bridged IPTV Configuration
A bridged IPTV configuration is comprised of:
one (or more) WAN connections one (or more) LAN connections –and- an interface grouping structure to bind all of the connections together
The more generalized bridged IPTV service configuration with multiple WAN connections is shown below.

Creating Bridged WAN Connections
To configure the SmartRG for bridged IPTV service deployments (with one or more WAN connections) start by creating the bridged WAN connections:
1. Create a Layer 2 interface following the instructions detailed in:
a. “Configuring the Layer 2 Interface (Ethernet)” b. “Configuring the Layer 2 Interface (ADSL)” or c. “Configuring the Layer 2 Interface (PTM – Supported on ADSL and VDSL)”
as appropriate for your particular SmartRG (Ethernet or DSL).
2. Select Advanced Setup -> WAN Service.
Figure 28 Selecting a Bridged WAN Service’s Layer 2 Interface
3. Select the Layer 2 Interface (created in step 1 above) from the drop down list and click
Next.
S m a r t R G © 2 0 1 2 C o n f i d e n t i a l P a g e | 37
NOTE
Some DSLAMs require multiple WAN connections to support IPTV services. Contact your DSLAM vendor for IPTV configuration details.
IMPORTANT NOTE
The IGMP bridged WAN connection MUST be the last bridged WAN connection created.
SmartRG™ Residential Gateways
4. Select “Bridging” and click Next.
Figure 29 Creating a Bridged WAN Service
5. Review the bridged WAN service summary and click Apply/Save if you are satisfied.
6. Repeat steps 1-5 as necessary to support your particular IPTV configuration (i.e. single or
multi-WAN connection).
7. Ensure “IGMP Snooping” has been enabled on the LAN as detailed in the “Use Case: Setting
Up the LAN” section.
8. Check “LAN(1-4)” – (This segments the four LAN ports into separate interfaces instead of a
single switched block of ports).
9. Click Apply/Save.

Configuring Your SmartRG™ - Common Use Cases
NOTE
The generalized (more complex) IPTV bridge group is detailed here. The majority of DSLAMs require only a single WAN connection to support IPTV services. In that typical case:
The “atm0” interface would provide routed WAN access for Internet services and
remote management –and-
The “atm1” interface would provide bridged WAN access for all IPTV related
services (multi-cast streams, middleware server access and IGMP signaling)
At the conclusion of step 9 your Layer 2 Interface summary (Advanced Setup -> Layer 2 Interface) will look similar to:

Creating Vendor ID Based Interface (Bridge) Groupings
To provide greater flexibility when connecting set-top-boxes to LAN ports SmartRG gateways support “Vendor ID Based” bridge groupings. Instead of adding specific LAN ports to the bridge group, you can specify the Vendor ID of the set-top-box. Any traffic received on any LAN port containing the specified Vendor ID will be bridged to the designated bridged WAN connection.
To configure Vendor ID based interface groupings, add only the WAN interface(s) to the bridge group and then specify the required Vendor ID(s) in the following list:

Configuring Your SmartRG™ - Common Use Cases
NOTE
The SmartRG family of gateways employs “Differentiated Services” (RFC 2474) to provide IP traffic QoS. When configuring QoS for various traffic categories the following Differentiated Services Code Point (DSCP) values or suggested:
Internet data – Best Effort (DSCP 0) IPTV – AF21 (DSCP 18) VoIP – Expedited Forwarding (DSCP 46)
NOTE
Some STBs pre-mark their IP traffic making classification a relatively straightforward task for the gateway. If your STB pre-marks its traffic, passing the DSCP mark through
Routed IPTV Configuration (Single WAN Connection)
The common routed IPTV configuration is virtually identical to the WAN connection configuration for Internet data services with one notable exception; the addition of quality of service (QoS).
While not an absolute requirement, applying QoS to LAN traffic (with higher priority given to STBs) ensures the timely and deterministic delivery of IPTV related uni-cast requests and IGMP signaling through the gateway. This provides repeatable, shortest time possible channel changes in the presence of other LAN traffic. A typical routed IPTV service configuration with only one WAN connection is shown below.
Figure 36 Routed IPTV Configuration (Single WAN Connection)
To configure the SmartRG for routed IPTV service deployments:
1. Ensure “IGMP Snooping” has been enabled on the LAN as detailed in, “Use Case: Setting Up
the LAN.”
2. Create a routed WAN connection as detailed in, “Use Case: Creating WAN Connections for
Internet Access and Remote Management.”
3. (Optional) Create traffic classifiers and priority queues for the various traffic categories on
your LAN (e.g. Internet data, IPTV and VoIP) as detailed in, “Use Case: Applying Quality of S.”

unchanged is suggested.
SmartRG™ Residential Gateways
Routed IPTV Configuration (Multiple WAN Connections)
It is also possible to create routed IPTV configurations with multiple WAN connections. The notable difference to typical routed IPTV configurations is the addition of one or more bridged WAN connections to support multiple multicast IPTV streams. Again QoS is suggested. A typical multi­WAN connection, routed IPTV service configuration is shown below.
Figure 37 Routed IPTV Configuration (Multiple WAN Connection)
To configure the SmartRG for multi-WAN connection, routed IPTV service deployments, follow the single WAN connection, routed IPTV configuration instructions above –plus- add bridged WAN connections using the instructions detailed in, “Creating Bridged WAN Connections.”

Configuring Your SmartRG™ - Common Use Cases
NOTE
The residential gateway plays no part in the prioritization of downstream traffic.
NOTE
Mediaroom based IPTV STBs place the DSCP18 mark on all upstream traffic.
Use Case: Applying Quality of Service (QoS) to VoIP and IPTV LAN Traffic
When deploying time critical services such as VoIP and IPTV comingled with common data services, it becomes necessary to prioritize the time critical, upstream LAN traffic over common data traffic (e.g Internet data and file transfers). Time critical traffic commonly includes SIP signaling (VoIP call setup/teardown) and IGMP signaling (IPTV channel change). The SmartRG line of gateways prioritizes time critical traffic using the “Differentiated Services Code Point” field in the IP header as defined by RFC 2474.
Traffic generated by LAN hosts such as VoIP phones, IPTV STBs and PCs is identified by “classifiers”
and placed into prioritization “queues.” Queues are emptied through the routed WAN connection
based on queue priority. Classifiers can identify traffic based on a number of criteria including: source/destination MAC address, source/destination IP address, protocol, DSCP mark, etc. This section describes a typical QoS configuration to prioritized upstream VoIP and IPTV traffic.
A typical VoIP/IPTV/data QoS configuration is shown below:
Figure 38 Typical QoS Configuration to Support VoIP and IPTV Services
VoIP traffic is identified by its source MAC/Mask (VoIP user agent OUI) and IPTV traffic is identified by the DSCP mark in its IP header. All remaining traffic is placed in the data (default) queue.
The QoS configuration process is comprised of three main steps:
Enable QoS on the routed WAN connection and enable QoS processing Create traffic queues to prioritize the different types of traffic –and- Create traffic classifiers to identify the different types of traffic
