Dynamic Connection Management System for Optical
Networks Applicability in a TINA environment

• Sten Hubendick, Leif Byström
• Broadband Networks, Telia Research AB

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

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.

Winchester Network

• Each node consist of OEXC, WDM transmission
  equipment and Router/Switches
• OEXC 16x16 1,2Gb/s
• WDM 8 2,5Gb/s channels

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
