54 Services QoS VoIP VConf IPTV Security

55 Challenges Connectivity problem management BGP policy Open access of the NOC information Shared trouble system Security Level 2 services Advanced services

56 Possible Paths policy based routing and politics based routing

57 The Real World Routing

58 Meet requirement by user AS network Policy Under the framework of TEIN2 Database IRR (who) Configuration AS-path prepend Predefined community Fine tune Traffic and flow monitoring End-to to-end performance tools AS A AS B AS C AS D

59 BGP Routing Under the framework of TEIN2 Try to provide the BGP routing as more flexible as possible to the connected networks Provide the online access to the routing, traffic and flow information

60 BGP Implementation (draft) Implement BOGON filters Implement prefix length filtering Implement authenticated BGP sessions Implement maximum prefixes Implement route dampening Implement route filtering (prefix-list or access-list or/and filter-list) Accept community tag Accept MED Accept aggregated prefixes, except for the policy based routing

61 Open Access of the NOC Information Access policy Under the framework of TEIN2 Tools and user interface Open software tools APAN NOC Abilene Observatory etc. In-house developed tools status/performance/routing/traffic/flow/equipment

62 Remarks

63 Remarks Under the framework of the TEIN2, we welcome suggestions and comments for the TEIN2 NOC operation SLA BGP routing Monitoring and measurement

64 Thoughts Global Academic NOC meeting NANOG, APRICOT, RIPE Video phone no time zone problem Shared trouble ticket system trouble shooting Shared end-to to-end measurement data optimize routing

65 On Network Operation Be Patient Knowable, Controllable Loging Redundance,, Backup Policy and Procedures One time one thing Loose Coupling Make Allowance
