Multicast is delivered to the customer’s port under a static subscription on a continuous basis. No setting up of PIM, MSDP or MP-BGP is required.

An easier and more reliable way to get television signals is to set up TV VLAN from the point of reception to the destination point. IGMP snooping must be disconnected. For OS Linux, disconnecting rp_filter may be necessary.

If the customer needs to receive television signals via router, make sure a successful RPF Check is conducted. One option is to request IP address from the 194.85.188.0/24 sub-network from MSK-IX technical representatives.

IP multicast technology is used to deliver and receive streams through dedicated communication channels (or isolated VLANs). If it is necessary to increase the reliability of delivery and reception of data transmission, by agreement of the parties, the use of Forward Error Correction (FEC) technologies are possible.

To deliver streams to consumers through the public Internet (in unicast mode), HLS, DASH, RTMP and SRT streaming technologies are used. To optimize network connectivity when delivering over the Internet, it is recommended that the consumer connect to public peering VLAN MSK-IX.

Note: if you have a need to transmit or receive streams in other formats, contact the administrative and technical representatives of the Medialogistika project.

Check the monitoring data for the television signal in question in the MY.IX.RU Customer Portal, in the section TV VLAN / Your TV VLAN. The data are updated in real time. If the data match your monitoring, please contact the MSK-IX 24/7 Technical Support.

If MSK-IX monitoring does not identify any problems, note that Multicast is transmitted using UDP, and so it is very important to ensure no loss during transmission. Throughout the route from the junction with MSK-IX to the reception point, the following conditions must be ensured:

• Switchboards and routers must be free of CRC errors (and other errors cased by the data transmission environment).
• There must be no errors caused by switchboard/router buffer threshing. Using QoS successfully tackles the problem.
• Storm-control multicast must be set up correctly.
• Communication channels must not be overloaded with traffic which has a priority equal to or higher than the priority of multicast streams with television signals.

If there is a transit operator between MSK-IX and the customer, these requirements are also valid for transit.

You can use both a designated and a shared switch port to connect to TV VLAN. A designated port ensures best quality thanks to better isolation and prevents the impact of other services. Therefore, a designated switch port is recommended.

• Designated switch port. Set it up in access mode.

• Shared switch port (common peering VLAN, private VLAN). In this case, the switch port must be in trunk mode. Numbers for TV VLAN and the services need to be agreed with the MSK-IX Technical Support.

You can use both a designated and a shared switch port to connect to VLAN Multimedia. A designated port ensures best quality thanks to better isolation and prevents the impact of other services. Therefore, a designated switch port is recommended.

• Designated switch port. Set it up in access mode.

• Shared switch port (private VLAN). In this case, the switch port must be in trunk mode. Numbers for VLAN Multimedia and service need to be agreed with the MSK-IX Technical Support.

Note: VLAN Multimedia does not match with common peering VLANs.

TV signals can be connected and disconnected in the MY.IX.RU Customer Portal, in the section TV VLAN / TV signals list.
