Agenda

Agenda

  • UDL Operation

  • UDL 13Mbps bandwidth extension

  • IPv4 Routing on UDL

  • Other Routing Issues

  • New network design in SFC

  • Security


Udl operation

UDL Operation


Topics

Topics

  • Report

    • UDL13Mbps extension and UDstation installation done

    • Keio establish maintenance contracet with UDcast for UDstation and UDbox

    • Backup UDstation and UDboxes will arrive soon

  • Backup UDStation box

    • Coming Soon

    • TBD Later

  • MTU 1500 on UDL

    • MTU 1452 on UDL should be legacy (SONY Feed problem)

    • TBD Later

  • Issues on UDstation 13Mbps Performance

    • Configuration is 13Mbps but actual output by MRTG is around 10Mbps

    • TBD Later

  • IPv4 routing on UDL

    • Install Private IPv4 for routing on the UDL (schedule and design)

    • TBD Later


Backup udstation and udbox

Backup UDstation and UDbox

  • Expected arrival date

  • Direction of operation

  • Expected topology including backup UDstation


Mtu 1500 on udl

MTU 1500 on UDL

  • Current status

    • 1500 on sfc-udl-feed and ITB

      • ospf6dではipv6 ospf6 mtu 1452

    • 1452 on others

    • OSPFv2 with ITB is okay

    • OSPFv3 with all uses if mtu 1452 definition in ospf6d.conf

  • AI3 Meeting後にOperator Meetingを開催して変更をします。

    • 各サイトのRRにて、UDL I/FのMTUを1500に変更します。

    • スケジュール未定

    • TSペイロード長を考慮したMTUを設定


Issues on udstation 13mbps performance

Issues on UDStation 13Mbps Performance


Udstation 13mbps performance

UDStation 13Mbps Performance

  • TCP tests on UDL:

    • Multiple wget sessions on SFC RO2:

      • web server is sfc-cpu, output is /dev/null

      • MTU is 1500

  • Output is around 10Mbps (less than smartbit results)


Comparing the results

Comparing the Results

iperf TCP results:

Around 11Mbps

Wget results:

Around 10Mbps

MRTG

Sfc-udl-feed:bge1


Testing direction and announcement

Testing direction and announcement

  • Do more tests to confirm

    • iperf vs wget

    • Smartbit UDP vs iperf UDP

  • If wget or iperf is less than Smartbit:

    • Why?

    • Contact UDcast?

  • Use tcpdump, then gets more accurate number

  • UDL maybe blocked for testing


Ipv4 routing on udl

IPv4 routing on UDL


Routing for ait and itb

Routing for AIT and ITB

  • BDL bandwidth changes due to UDL 13Mbps migration

    • SFC-ITB and SFC-AIT are 128kbps

  • OSPFv2 is running on UDL

    • Neighbor: ITB, AIT should be neighbor, too.

    • Prefer routes via UDL than BDL


Install private ipv4 for routing on the udl

Install Private IPv4 for routing on the UDL

  • Background

  • Discussion

  • Design

  • Schedule


Other routing issues

Other Routing Issues


Sfc installed a cisco router

SFC installed a Cisco Router

  • SFC installed Cisco with 5 I/Fs

  • Show current status and changes made in the routing /topology

  • Current status:

    • Tunnel with RENATER using sfc-c7200-gate

    • Failure on advertising AI3 prefix to RENATER

      • Trouble shooting is on-going

  • Next:

    • Move c7200 to AI3 rack

    • BGP peers Fujisawa cisco 12000

    • Push APAN-JP and TEIN2 to activate PIM-SM and MBGP


Freebsd specific issues

FreeBSD-specific Issues

  • Routing socket issue FreeBSD 4.10 ~

    • Kernel doesn’t inform all route deletes if too many deletes in a small period

      • Ex: route flush

    • Result: Zebra doesn’t reinstall all routes deleted by, e.g., route flush

  • Husni patched zebra code

    • Already run on some routers in AI3

    • Should let others know


Multicast routing xorp issues

Multicast Routing: XORP Issues

  • SOI Asia is using XORP 1.1

    • Some bugs. E.g.: doesn’t update MRIB if there are changes in kernel

  • Should upgrade to XORP 1.3 + patches

    • Unpatched XORP 1.3 has next-hop interface problem in MRIB


Ai3 sfc network middle term design

Todos for preparation

Todos for preparation

  • Show the final topology

  • Show the intermediate topology for the near future (Change topology with current cisco) and discuss routing and addressing

Generic requirement

Generic Requirement

  • Less operational cost and more stability

    • Integrate some PC routers to Cisco routers

    • Distinguish challenge and stable operation (ex. sfc-udl-feed)

  • Capability of fiber optic connections in backbone

  • Redundancy against hardware troubles

    • Backup for core routers

    • Backup for UDstation

  • Interoperability between challenge and stabile operation IPv6 deployment


Less operational cost and more stability

Less operational cost and more stability

  • Integrate some PC routers to Cisco routers

    • Decrease the risk for hardware trouble

  • Trials with PC router like sfc-udl-feedv.s backup using Cisco router

    • Need to clear out the minimum interoperability between challenge and stable operation


Capability of fiber optic connections in backbone

Capability of fiber optic connections in backbone

  • For the future operation, routers and switches connecting to the backbone may need gigabit Ethernet interface


Redundancy against hardware troubles

Redundancy against hardware troubles

  • Duplicate some important routing entities

    • sfc-gate

    • sfc-udl-feed

    • sfc-sat

    • sfc-udstation


Ipv6 deployment

IPv6 deployment

  • Server upgrade

    • WEB Cache

    • DNS

    • SOI-Asia applications?

  • Routing in the UDL network

    • IPv6 for all SOI-Asia partners

    • Private IPv4 for a part of partners

      • BDL partners
