Operation BOF
husni
tokyo, 2003/06/21
Agenda
• Usage of UDL(15minutes)• Redundancy of satellite routers(10minutes)• IPv4 Address assignment policy(15minutes)
– request based– return not used address -> use it in each satellite link– each satellite link use /29
• multicast(10minutes)– Let's use PIM
• policy routing(10minutes)• Zebra• Security
Multicast
• PIM on UDL: – SFC, AIT, ASTI (4th week of July), ITB (after 7/
2, in July), IOIT (need to check)
• PIM on c-band BDL:– sfc-sat is ready for PIMD, but not operated– USM: need assistance to configure
• No PIM on Ku-band BDL
Announce
UDL Usage Situation
• The UDL is getting fully utilized
• Need a clear policy for maintaining QoS
• Issues:– Shared link– SOI-ASIA use (lectures, sakurafubuki3rd)– Commodity traffic
Toward The Best UDL Usage
• Classify traffic– Multicast / Unicast– Partners / SOI-ASIA
• Identify priority requirements
• Define QoS policy
• Technical issues
Traffic Classification
[S1] SOI-ASIA lectures
[S2] SOI-ASIA related traffic (web, etc.)
[S3] Sakurafubuki3rd
[P1] Policy routed traffic
[P2] UDL prefix’s generated traffic
Priority Considerations
• SOI-ASIA multicast traffic [S1][S3] is for everyone– not 24x7
• Policy routing [P1] is to be operational
• There is no need to generate unnecessary traffic from UDL prefixes– can be policy-routed easily [P2]– limit the use to certain clients [S2]
QoS Policy Proposal
• Priority order1. [S1]
2. [S3]
3. [P1]
4. [P2][S2]
• How much bandwidth?
• Implementation schedule?
Technical Issues
• What software to use?– DUMMYNET– altq
• Partner’s experience?
What we want
• Priority control– DUMMYNET– Altq
• Traffic shaping– Limit unicast when there is multicast
• Bandwidth reservation
Satellite Routers Redundancy
• Current:– Cisco bridging mode (except SG: schedule Mid. July
~ Aug)– sfc-sat serves as the single router (use 4-port etherne
t)– P2P netmask /30
• Next:– Cisco bridging mode (except SG)– Add another sat router: sfc-sat2– P2P netmask /29
Redundancy: Issues
Add sfc-sat2
IPv4 address usage– some sites have low address utilization
Address Change Schedule
• JPN:– /29 x 7– Change /30 x 7 into /29 x 3– Need /29 x 4 = /28 x 2
• DNS issues– USM: no problem– IOIT: no problem– AIT: no problem– ITB: no problem– ASTI: no problem– TP: no problem
Ku-band Address Change Plan
• NARA-AIT 24.232 /29• NARA-ITB 24.224/29• Relocate NAIST-SFC ATM P2P VLAN (24.240/3
0)• Grab ITB’s latter half (24.64/28)• Move AIT to ITB’s latter half (24.80/28)• Schedule (need to coordinate)
– Naist: 2 weeks from now– AIT: wait for Yoo comes back from France– ITB: after 7/2– After 7/2, plan through ai3-ix@
C-band Address Change Plan
• Needs /29 x 5• NUOL: reserve address, postpone action• ASTI: 26.96/29 (it’s up to SFC)• TP: 26.104/29 (it’s up to SFC)• USM:25.176/29 (no expected date for link to
come back, do it right after 7/2 is ok?)• IOIT: 25.184/29 (it’s up to SFC)• Schedule: after 7/2 (let’s work on schedule!)
C-band Address Change Plan
• Reclaiming, New prefix:– 202.249.25.32/28 ASTI NOC– 202.249.25.64/28 USM NOC– 202.249.25.48/28 TP NOC– 202.249.25.80/28 IOIT NOC
• Schedule: same time with satellite link renumbering if it is convenient
Policy Routing
• ASTI: HTTP traffic; updates from bio-mirror (need specifics)
• ITB: no change on request
• IOIT: no request at this moment
Multicast
• PIMD on UDL: AIT, ASTI (July), IOIT (need to check), ITB (July)
• PIMD on C-band BDL:– sfc-sat is ready for PIMD– USM needs assistance on PIMD
• No PIMD on Ku-band BDL
USM EGP Routing
• No issues in IPv4
AI3 Website• No detailed from Jun
– Events?– Activities?– Publications?– Kotaro will confirm with Jun
• SFC will give content example– esp. in operational– propose a template in July
• Need topology map from partners– Want the latest version in July– Please renew at site update session
• Operational information– Topology map– Tips– Policy routing?
• Requests from Suguru– Webdav, for sharing PPT– Contact information (MoU, operators)– For visitors:
• Products and Publications• Mission statement• Organization structure• Contact info• Events
Web
• For US:– Related organizations & contact points (APAN, Intern
et2, Star*– Holidays & important days in each country– Operational information
• Persons:– Kotaro : in charge for web remake?; confirm with Jun; – Ayumi : helps kotaro– Baba : design?
• Easy to update• File uploading areas (webdav)
