• Keep machines running
• Security Issues
• Monitoring Issues
• Challenges
• Milestone

3
Current Situation

• Connection
• Full time
• Part time
• Network Vulnerability
• Security Issues

4
Basic Network Composition
C-band UDL Network
SONY-BOX
Receiver-Router
SOI-Server
Gateway-Router
Campus LAN / INTERET
Terrestrial Link / Satellite Link

Commodity Traffic (1)

• Question
• Can commodity traffic for SOI-ASIA partners flow
  into the C-band UDL??
• Requirement
• Highest priority for SOI-ASIA lectures

6
Policy for using UDL (re-visited)
priority
SOI-ASIA Lecture
SAKURAFUBUKI
Policy Routing
UDL Prefix
Commodity

• We will learn requirements and problems, and more
  from monitoring traffic
• Improvement will be made based on experience

7
Commodity Traffic (2)

• HTTP traffic using proxy (SOI-Server) can flow
  into the UDL
• And any traffic regarding SOI-ASIA Project
• sometimes other traffics prioritized rather than
  your commodity traffic

8
Keep machines running

• Important services should not be shut down
• Domestic (local) Services
• Keep monitoring something
• To make routers and servers running
• Physical machine protection from surge, heat
• Uplink availability
• But you may have downlink every time

9
Security Issues

• Application Vulnerability
• Too old OpenSSH, SSL
• NetSNMP (UCD-SNMP)
• Other services?
• Does any service you use have its vulnerability?
• Check and Update

10
Monitoring

• Is pull method best for us in C-band UDL
  Network?
• Can RO sites respond every time?
• Redesign of MWD in UDL Network
• In the scope of my master thesis

11
Challenges

• OSPF
• Store the tips and try
• Multicast
• While the SOI-ASIA lectures are not scheduled, we
  can try pimd
• IPv6
• IPv6 capable SONY-FEED will be installed in SFC
