Model for e2e links
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
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


Technical building blocks for e2e operations
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


Status information for e2e monitoring system
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


Agenda1
Agenda

  • Use case

  • Providing the data

  • Visualisation

  • Achievements

  • Next Step


Data exchange for e2e monitoring archive scenario

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.

Data Exchange for E2E Monitoring – Archive scenario

Connect. Communicate. Collaborate


Other data exchange for information
Other Data Exchange (for information) analyse them and pass the information to a java class.

  • 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: analyse them and pass the information to a java class.

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
