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

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)
  • 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
