perfSONAR Workshop

• Various network services use a common "Information Services plane" that allows users to discover network topology and the location and capabilities of network services within that topology. As global federation of network services occurs, the standardization and flexibility of the network-centric Information Services becomes even more critical

• Currently, the same infrastructure is used by– DCN– perfSONAR– Phoebus data movement service

• In order to help catalyze and focus the development of these common information services, the Internet2 Network Advisory Committee (NTAC) has commissioned the creation of this working group

• The group will work to – further define the role and functionality of Information Services– drive design and development– Interface with standards and community organizations (IETF, OGF, GLIF)

Introduction

• Control Plane– Host discovery– Service discovery– Pathfinding

• Performance Measurement– Archived data discovery– Measurement point discovery

• Network topology abstractions– “What is close?”– This includes proximity to the querier, proximity to a path,

proximity to another resource

8 – 04/20/23, © 2009 Internet2

Use Cases – Closest MP

9 – 04/20/23, © 2009 Internet2

Use Cases – Dynamic Circuits and IS

• OGF 27 (March 2010)– NM – Discussion on the base document. Will enter WG last call

and be ready for OGF Sheppard process by OGF 28– NMC – Progress on ‘base’ document. Discussion on Result codes.

Will be adding a new document to describe transport medium (e.g. HTTP over SOAP)

– NML – First document published. Working on ‘objects’ and schemas.

• OGF 28 (Late June 2010)– NM – Finalization of document– NMC – First complete draft of base for WG comment

OGF Update

• Utilizing UNIS schema in the ‘RSpec’ (ProtoGENI description language)

• perfSONAR being used to measure ProtoGENI's switches at Internet2 PoPs (SNMP MA installed at UDel)

• Interacting with the I&M working group to recommend perfSONAR use within ProtoGENI– Integration of perfSONAR with other measurement projects– New uses cases to consider, including migration of data from

experiments to long term storage.• Implementing ProtoGENI testbed at UDel for I&M development• LAMP Project is integrating perfSONAR monitoring into the

ProtoGENI infrastructure and experiments– Demo at GEC8

ProtoGENI Update

• Use of information services (NML/UNIS) in circuit monitoring.• Defining a schema extension that incorporates ESCPS-specific

elements (e.g. flow entities, network rules). • Next Steps:

– Looking at the TS to track topology resources at the end-site– Development of statistics collection ("Measurement Collectors")

for hosts– Active circuit monitoring

ESCPS Update

• Using Netlogger to find weaknesses in the gLS/hLS• Early results:

– Not CPU/IO/Memory Bound– Potentially blocking on threads in the XML Database

• Roadmap– Construct a simulator to test in a controlled environment– Evaluate transaction subsystem– Speed up certain aspects (summarization, registration)– Explore new databases (last resort)
