3. NASA MSFC Mission Operations Laboratory MSFC Page 3 Ku Forward Capability Summary  The ISS Ku Forward capability (a.k.a. OCA) used internally by MCC-Houston to support systems activities (e.g. plan uplinks) is being extended for use by the POIC Cadre and PD teams  Ku Forward allows users access to devices connected to the Payload LAN  Ku Forward uses standard Internet Protocol (IP) communication protocols.  Primary communication (command) path for majority of payloads is still S- Band commanding, and Ku Forward commanding will be assessed on case- by-case basis  Ku Forward “commands” are not defined in the Command & Telemetry Database and do not go through command server or any MDM for uplink/execution.  Hazardous and Critical commands will not be sent via Ku Forward and can only be sent by the PRO via S-band.  ISS Program has defined an approved set of standard IP communication protocols that are allowed

7. NASA MSFC Mission Operations Laboratory MSFC Page 7 Packet Routing Example  This diagram shows the process to get packets properly routed from the user to the onboard destination and back to the user  To make the connection possible without violating security requirements, the HPEG uses a process called Network Address Translation (NAT) to automatically change the addresses in the user’s source IP packet from the secret address to the public address  During the uplink, the HPEG Proxy IP address is changed to the Onboard Destination IP address  During the downlink, the Onboard Source IP address is changed to the HPEG Proxy IP address

8. NASA MSFC Mission Operations Laboratory MSFC Page 8 Verification and Testing Results  Phase I testing summary  DMC verified Ping functionality to the PEHG-1, PEHG-2, and COL PEHG  PRO verified Ping and RDP on Express Laptop 1  AMS will use SSH to the AMS Laptop as a pathfinder  At this time, ER1 and ER2 laptops have completed Phase 1 checkout. It is likely that by the time this presentation is read by a trainee, more laptops will have completed Phase 1 checkout.  Phase II testing summary  DMC verified Remote Desktop functionality following install of Network Monitoring System onboard  PRO verified CFDP functionality on the Express Laptop Computers by uplinking and downlinking files to and from the laptop.  PRO verified drive mapping functionality on the Express Laptop Computers by uplinking and downlinking files to and from the laptop.

9. NASA MSFC Mission Operations Laboratory MSFC Page 9 Cadre Use Cases  PRO will use Ku Forward to perform file uplinks to EXPRESS Laptops during Phase II  DMC plans to execute pings to onboard equipment as necessary during phase II operations and beyond. Additionally, DMC expects to utilize Remote Desktop to access the Network Monitoring System laptop following its install in late-2014/early-2015  If a user is having difficulty connecting to their destination, DMC and PRO will attempt to identify whether the issue is an onboard configuration issue or a ground systems issue. If the issue is onboard, PRO and DMC will use standard anomaly resolution methods and procedures to identify and correct the problem. If the connection problem is identified as a ground systems issue, the problem will be turned over to Marshall Data and the IST  After doing Phase I checkout on an EXPRESS laptop, these operations are possible:  Start/stop payload applications on EXPRESS laptops  Copy/rename/delete files as needed  Troubleshooting laptop connectivity (ping or just trying to log in)  In the future:  When RIC Release 9.2 is loaded on a rack, we will have to use Ku Forward for file downlinks from that laptop (this should be fixed in Release 10)  File uplinks for PDs that do not have File Authorization Table (FAT) names or that have files to big to go through PLMDM (8MB limit)  Payload Application installation on laptops  Virus definition updates on laptops
