2What is IPNOC?
- Manages IP Operational Networks (IONET)
- 24x7 Staffed Operations Center
- Pro-Actively Monitors Network Devices
- Troubleshoots Network and WAN Problems
- Troubleshoots Connectivity and Dataflow Problems
(end users) - Works with other CSOC and Code 290 Organizations
to Engineer and Implement New Routed Data
Services on IONET
3IP Operational Networks (IONET)
- IP Transition (real-time mission critical)
- IONET Closed LAN (at GSFC)
- IONET Open LAN (at GSFC)
- IONET Open WAN
- EOSDIS Backbone Network (EBNET)

5IPNOC Troubleshooting Tools
- Network Management System (NMS)
- COTS software
- Custom IPNOC apps to supplement COTS
- Network Sniffer/Protocol Decoders
- WAN Circuit Troubleshooting viaTech Control and
Host Center Support - End User Input and Assistance
- Vendor Support
6Commercial-Off-The-Shelf (COTS) Issues
- The priority for fixing bugs and adding features
is determined by COTS Vendor, not NASA IPNOC - Our demands for performance, redundancy,
recovery, and manageability frequently exceed
those of the vendor and its typical customer - Vendor can chose to drop support, product line,
change focus, or go out of business possibly
leaving us without vendor support
7IP Transition Network
- Mission Real-Time Critical Network
- UDP Multicast Data
- WAN or Network Errors will result in Lost
Commands or Telemetry - High Levels of Redundancy in order to ensure
availability - NASCOM 4800 bitblock encapsulated in IP
- 94 Routers, 70 WAN lines

10What makes IONET different(than average IP
network)
- heavy use of udp multicast data flows for
critical data - serialized data (encapsulated in IP) requires
very consistent timing in order for spacecraft
and end-users to maintain lock on the data - high performance requirements (very low tolerance
for errors) - high redundancy and desire for immediate
fail-over - critical nature of operations (manned
spaceflight, billion dollar spacecraft) - high-level of coordination required with users
before taking any actions which may impact user - little room for mistakes
