Overview

• Transport Middleware• Performance Measurement Requirements• Measurement Tools (active)• perfSONAR PS Motivation• Services

• SNMP Based MP/MA• Lookup Service• Topology/Status Service• Pinger Based MP/MA• Visualization

• perfSONAR Releases

Transport Middleware (Phoebus)

• Session-Layer transport abstraction• Improves end-to-end throughput for users• Depots on the ingress/egress points of

backbone networks mitigate the effects of misconfigured hosts and edge networks

• Allows transparent use of network features like cross-domain dynamic circuits

Phoebus - Deployed

• Allocate dynamic circuits using DRAGON

• Password authentication

• Configuration per route/host/user

• UDT for inter-depot communication

• Transparent operation (library, iptables)

Phoebus - Current Work

• Separating front-end (control plane) from back-end (data plane)• Allows creation of new front-end services

• Constructing a web services based front-end• Andy Lake for Google Summer of Code

Phoebus - Future

• Simple file transfer tool • Transparently use Phoebus/Dynamic

Circuits• Utilize Measurement Infrastructure• Help find best routes, provide information

about paths and achievable bandwidth• Leverage Control Plane• Allocate dynamic circuits across HOPI

• Authentication and Authorization

Performance Measurement Requirements (Internet2 network support)

• Deployed on Internet2 Network• Software: perfSONAR, BWCTL, NDT, OWAMP• Goals: IU NOC Support *, proof of performance for Application Community

• Meet the needs of the LHC Application Community (T0-T3)• Partnership with GEANT2 JRA1, ESnet, RNP to meet that need

• Packaged perfSONAR solution for US connectors and universities• Ease of deployment is key *• Veneer on existing NOC solutions rather than a new solution *

• Integrated into a Cyberinfrastructure Solution• Support DRAGON• Rely on common AA infrastructure• Common elements (AA, Discovery, Topology)

• * Drives the need for a perl-based packaged solution, perfSONAR-PS

Measurement Tools (active - at all router locations)

• OWAMP (latency)

• 3.0c (RFC 4645 version) available now

• Regular tests between all routers, and on-demand

• BWCTL (throughput)

• New version with more ‘testers’ available Aug

• (Testing on Internet2 network July)

• Regular tests between all routers, and on-demand

• NDT (User Diagnostic)

• 3.4.1 available now

• Latest version added better logging and error handling

NPToolKit

• Recent versions of Measurement tools installed and pre-configured

• Knoppix Live-CD bootable system

• Current Version: 1.7

• http://e2epi.internet2.edu/network-performance-toolkit.html

perfSONAR Motivation

• Most organizations can do monitoring and diagnostics of their own network

• Networking is becoming an increasingly cross-domain effort

• Monitoring and diagnostics must also become a cross-domain effort

perfSONAR

• A set of protocols and schemas for implementing a SOA for sharing and controlling network performance tools

• A community of users and developers• A set of software (the sample implementation)

perfSONAR-PS Motivation

• Create separate implementation of perfSONAR standard

• Use same protocol/standards

• Proof of interoperability (strengthens the standard)

• Targeted for University NOC deployments

• Lightweight

• Easier to deploy/manage

• (We were unable to convince our primary users to deploy

Java services due to the complexity of dependencies)

perfSONAR-PS Services

• Focus on development of major perfSONAR components• SNMP Based MP/MA• LS• Topology• Link Status

• New additions• OWAMP/BWCTL• Traceroute• Pinger (SLAC)

• Contact Jason or Jeff if you are interested in testing pre-releases

SNMP Based MP/MA

• Pre-release Versions Deployed• Internet2 Network• ESNet• Georgia Tech/SLAC/University of Delaware

• Compatible with perfSONAR-UI

Lookup Service

• Single Domain Only

• Features same XQuery based interface

• Currently being tested for compatibility with perfSONAR Java LS.

Topology

• Topology registration/query system in development

• Actively being updated w/ Control Plane partners

Status Service

• Status MP/MA to provide E2EMon functionality in development

• Different architecture• Smaller ‘status’ service, with a transformation

service to combine Topology/Status for E2EMonMP/MA interface

Pinger Based MP/MA

• Joint effort between Fermi Lab and SLAC• Present views of historic Pinger data• Expose interface to schedule live tests

• Development and integration into perfSONAR-PS based on LHC-OPN requirements

Visualization

• Utilizing the plugin architecture of perfSONAR-UI• Data visualization beyond network utilization

• Google Maps• Utilization by physical location• 'Weather Map' of Internet2 Network

• Web based speedometer to interact directly with MA code

Other Services (in development)

• Traceroute MP/MA• Joint effort between UD and SLAC• Integrate into visual traceroute tools

• Ping MP/MA• Features interface for on demand and scheduled

tests.

• OWAMP MA• Make regular results available

• BWCTL MA• Make regular results available

perfSONAR-PS Releases

• Currently exploring testing and packaging strategies• Releases will ultimately be CPAN based• Standing issues include configuration/automation

help.

• Versions of SNMP MA and LS will be available this fall

• Pre-CPAN versions will be available for LHC commitments in August (using CPAN conventions)

Summary

• Tools to leverage new network capabilities from an ‘end-user’ application (phoebus)

• Tools to do network monitoring and diagnostics

• Tools to federate network monitoring and diagnostics
