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
