    1. Broadband Networks, Integrated Management & Standardization Nobuo FUJII ITU-T SG4 Vice Chairman NTT Network Innovation Laboratories nobuo@exa.onlab.ntt.co.jp

    2. Broadband Networks and Services- Network Technologies - • Home Network • Access network • Transport network • Server network • IP network Residential Gateway Centric Ether network base 10Mbps-100Mbps Access BPON, DSL base 10Gbps Link, IP routers GMPLS enbaled OTN Cluster Network, GbFC,iSCSI, 10G standard IP routing Muticast, Diffserve,etc. Braadband Networks , Integrated Management & Standardization

    3. Broadband Services • Contents Delivery Applications • Archived Contents (Point-to-point) • Streaming Contents (Multicast) • Uni-directional to Bi-directional Contents holder SV RG CDN Home ntwk RG HN RG HN user user Braadband Networks , Integrated Management & Standardization

    4. Server Network IP Network Transport Network Broadband Network Architecture Contents Delivery, User Data Cash Portal Gateway, Multimedia com. Streaming, Archiving, Cashing Distributed Processing engine Home network ASP networks ISP networks Various CoS support, IP multi-cast Low latency, Bandwidth Guarantee Bandwidth allocation, Secure transport Reliable transport. Cut through, etc. Network Operator networks Braadband Networks , Integrated Management & Standardization

    5. Calling Party Call Controller Network Call Controller Called Party Call Controller 1.Call request 2. Call indication 3. Call confirmed 10. Call confirmed 9. Connection confirmed 4. Connection request Routing Controller 5. Route query Connection Controller 6. Route info. 7. Link connection request 8. Link connection confirmed 7. Link connection request Link Resource Manager Link Resource Manager End-to-end Management of Transport Network- connection control procedure- • Connection establishment component in ASON Braadband Networks , Integrated Management & Standardization

    6. Connection request E C A B D Connection request msg. Equipment Node Established connection Subnetwork End-to-end Management of Transport Network- routing aspect - • Source and Step-By-Step Routing for ASON provides an end-to-end connections of the transport network. (alternative: Hierarchical routing) Braadband Networks , Integrated Management & Standardization

    7. Home- network CDN network 1.Service request 3.Service grant (Set up information) 2.User authentication Multi-channel Contents stream (program info) 4.Set-up request (Set up information) IP network 7.Contents delivery 5.Multi-cast configuration 6.Bandwidth request/allocation 8.Performance report Transport network Case study: CDN service management • Scenario: User receives a stream contents from CDN network Braadband Networks , Integrated Management & Standardization

    8. Management of the broadband networks • Goal: End-to-end management of sub-networks: • Service management rather than network management. • Requirements for sub-networks: • Rapid service provisioning; • Autonomous service restoration; • QoS sensible application acceptance. • Management areas of importance: • Configuration: service provisioning, autonomous systems configuration, • Performance: QoS report. Braadband Networks , Integrated Management & Standardization

    9. Design method for the broadband network management • Conditions • Diversified(& ing) Management Protocols • SNMP, CORBA, CMIS/P, XML… • Diversified(& ing) SDOs • cf.SDO(Standard Development Organization) • Approach • Protocol Independent Interface Design • Use of UML method • Electric document exchange between entities Braadband Networks , Integrated Management & Standardization

    10. Issues on the design method • UML • What are the protocol independent common services, naming and addressing methods? • Conversion to SNMP, CORBA, GDMO models • Use of XML for document exchange • What are Rules, Objectives and Guidelines of XML use? • Development of the GTDD • cf. Global Telecommunications Data Dictionary Braadband Networks , Integrated Management & Standardization

    11. tML Framework Scope Complete Trading Partner Spec. Business Process Scenario Trading Partner Profile/Agreement Implementation Infrastructure Profile security Message Structure Data & Vocabulary Header & Encoding Rules tML Framework Rules, Objectives, Guidelines for Development of tML Schema Business Document Spec. Payload Business Rules tML Schemas tML Document Structured according to tML Schemas Developed according to tML Framework Reliable Connectivity Implementation Infrastructure Profile Braadband Networks , Integrated Management & Standardization

    12. Conclusions • The broadband network as integration of sub-networks: • Home network, ASP networks, ISP networks, and Operators networks. • Vertical integration of the broadband network management: • Protocol independent management interface design: • Naming, Addressing, Common Service issues need to be solved. • There are standardization efforts in ITU-T: • ASON (Automatically switched optical network) Rec.G.8080/Y.1304 • tML (Telecommunications Markup Language) Rec.M.3030 • TMN methodology amendment Rec.M.3020 Braadband Networks , Integrated Management & Standardization
