## Multicast Update 

- NISN Quarterly Customer Videocon
- January 26, 2009
- Ken White

## Multicast 

- Multicast is enabled on the NISN routed data network.
- Included several examples of requirements which have been recently implemented.

## University of Delaware Implementation

- Customer Requirements
- -  Provide MSFC ISS Video via IP connection to the University of Delaware in support of InSPACE-2

## NSSTC Implementation Overview

- Customer Requirements
- Configure and implement multicast peering between NISN and NSSTC on an existing BGP session in support of MSFC Desktop TV.
-  NSSTC would like to communicate with MSFC via multicast with the destination join being MSFC TV.
- Implementation Requirements
- Configure mBGP and MSDP on the MSFC SIP core router as well as the NISN managed NSSTC border router.

## Engineering Solution Overview

- BGP session between NISN WAN and NSSTC currently exists
- Multicast extensions for BGP need to be configured on NISN SIP core router at MSFC and NISN managed NSSTC border router.
- Once configuration is completed, MSFC (which already is configured for multicast with NISN), will be able to communicate with NSSTC via multicast.
- Configuration of multicast extensions for BGP will be handled via an NMCC request.

## MCDTV Implementation Requirements Overview

- Customer Requirements
- Enable multicast and increase PSLA bandwidth by 1.5-2.0 Mbps
- Summary:
- MCDTV would like to create two contingent backup sites.
- Enable Multicast routing on PIP interfaces facing MCDTV equipment
- In the event that HQ could no longer be the focal point of the MCDTV transmissions from other centers, enabling multicast would allow the data stream to also be sent to the backup sites, GSFC and JSC, at the same time
- Increase PSLA bandwidth for MCDTV on each encoder throughout the network by ~2Mbps to allow for all encoders to stay up passing keep alive type traffic.
- Implementation Requirements:
- PIP core is already multicast enabled
- Activate multicast on MCDTV interfaces.

## MCDTV  Solution Overview

- MCDTV is an existing NASA service.
- Currently HQ is the centralized point for all transitions
- A broadcast is sent from a MCDTV center, (Red Center), to HQ where the video decoder is located.  The stream is decoded at HQ and then sent across a leased line to GSFC for uplink to the satellite.
- The project requested that the service be transitioned from unicast to multicast so their streams can also be delivered to GSFC and JSC (Blue Centers) as secondary and tertiary sites in the event that the decoder at HQ fails.
- Multicast routing is an existing service/protocol on the PIP network
- To meet this requirement, multicast would be enabled on the MCDTV interfaces.

## Other Implementations

- The ISS Video feed is being multicast to other sites which have agreements with NASA
- University Colorado of Mines
- A second MIT implementation
- Canarie Multicast to support the Canadian Space Agency
- There is also a HOSC multicast feed into Marshall Space Flight Center
