Model for E2E Links

• E2E Links are dedicated optical multi-gigabit
  connections
• Essentially P2P links (circuits) framed as
  SDH/SONET or Ethernet
• Cooperation of several NRENs needed to operate
  E2E Links
• Users need Single Point of Contact (SPOC)
• E2E Link Coordination Unit (E2ECU) brings
  together Users and NRENs

Basic Characteristics of E2E Link Monitoring

• Status information corresponds to network layer 1
  and 2
• Status information is logical abstraction
• Multiple technologies and vendors used to provide
  a e2e service.
• No information about physical devices necessary
• Domain and Interdomain (ID) link status provided
  by NRENs
• E2E link status aggregation of NREN and ID links

5
Technical Building Blocks for E2E operations

• E2ECU as Single Point of Contact (SPOC)
• 30 NRENs participating
• Several hundreds of E2E links expected
• Common Tools
• E2E Monitoring System
• CMDB
• perfSONAR compliant monitoring data exchange
• XML registry file schema integrated within the
  NMWG XML schema

6
Status Information for E2E Monitoring System

• Operational States
• Up link is available
• Degraded link is up, but has reduced
  performance
• Down unavailable
• Unknown state is unknown
• Administrative States
• NormalOperational
• Maintenance
• TroubleShooting
• UnderRepair
• Unknown

Data Exchange for E2E Monitoring Archive
scenario
Connect. Communicate. Collaborate

• NREN in charge of retrieving the data from the
  NMS/DB to analyse them and pass the information
  to a java class.
• About 700-1000 lines of code for GÉANT 15 days.
• JRA1
• Provides the mySQL MA service code
• maintains it.
• Provides the script to write into the DB
• JRA4 in charge of the E2E NOC visualisation.

Other Data Exchange (for information)

• Measurement Point Service for Alcatel NMS
• Can currently retrieve SES, UAS, ES, BBE from
  Alcatel NMS via IOO module
• On demand
• Reference implementation
• Beta version of software available for download
• Measurement Point Service for SNMP
• SNMP.get
• On demand
• Beta version of software available for download

Data Exchange for E2E Monitoring proxy Scenario

• JRA4-WI3 part
• Retrieve data from NRENs
• Aggregate states for E2E links
• E2E link status visualisation (and other) tools
• NREN part
• Retrieve data from NMS/DB
• Calculate states for links
• Write data into XML registry file
• Done in real-time
