  1. Dynamic Connection Management System for Optical Networks: Applicability in a TINA environment Sten Hubendick, Leif Byström Broadband Networks, Telia Research AB Sten Hubendick, Leif Byström

  2. Introduction • Have an IP over WDM network testbed implemented in the Stockholm area. • Evaluating how to provide network services and integrating connectivity with higher layers (ATM,SONET/SDH,IP) • Here TINA can fill the role as the enabling network management architecture Sten Hubendick, Leif Byström

  3. Purpose • Purpose of Winchester • Realize Network Services in Physical Layer • Traffic Driven Reconfiguration (WLS) • Protection Switching • VPN • IP over Gigabit Ethernet over WDM • Evaluate Distributed Management Concepts • Show the applicability of TINA in an IP over WDM network. Sten Hubendick, Leif Byström

  4. Winchester Network • Each node consist of OEXC, WDM transmission equipment and Router/Switches • OEXC: 16x16 1,2Gb/s • WDM: 8 2,5Gb/s channels Accelar 1200 Acclear WDM OEXC 12000 Ericsson , Kista WDM OEXC Telia, Östra Vasa Acclear 12000 WDM OEXC Juniper M40 OEXC WDM Telia, Farsta Ericsson, Cisco 12000 Kungens Kurva Sten Hubendick, Leif Byström

  5. Kista Östra Vasa Farsta Kungens Kurva Testbed Location • 4 nodes in Stockholm area • Part of EURESCOM P1014 Sten Hubendick, Leif Byström

  6. WDM WDM WDM WDM NMS Central Agent x 4 nodes WDM MUX/DEMUX SNMP Interface Agent CORBA Network Node Agent XPS Physical Fiber NMS Distributed Agent TCP/IP Opt Rx/Tx UDP/IP CORBA/IIOP Architecture • Physical network • CORBA environment • Network Node Agent • NMS Central Agent • NMS Distributed Agent NMS Distributed Agent Sten Hubendick, Leif Byström

  7. Network Manager • Automatic path provisioning • Multicast by manual path selection • Protection/Fault restoration • Preemption of low priority trails • Disjunctive protection path Sten Hubendick, Leif Byström

  12. TINA Informational Mapping • The OEXCUnit object inherits from the ManagedNetworkElement in the RIM v4.0. ManagedNetworkElement (from TINA NRIM 4.0) << CORBAStruct>> OEXCUnit (from WIM) Sten Hubendick, Leif Byström

  14. Summary • Need for Architecture enabling interactions with other LNW Architectures • TINA can be used as enabling technology • Well specified model for connection-oriented network technologies • IPCM WG scope enables interactions with connectionless network technologies Sten Hubendick, Leif Byström
