Network Service Development (JRA4) Objectives

• JRA4 will provide common interfaces between
• Grid middleware and Network Resources

Grid Middleware
Consumer of Resources Information

• OGSA requirements
• Self contained
• Modular entity

Network Services
JRA4

• IP Premium
• MPLS paths tunnels
• Light paths
• Network Metrics
• Performance

Network Resources Information

• Advertising Resources
• Publishing Information

JRA4 Tasks and Context

• Main sub-activities
• Bandwidth Allocation and Reservation
• Network Performance Monitoring and Diagnostic
  tools
• IPv6 uptake
• DANTE already deploying basic infrastructure in
  GEANT (current GN1 and the coming GN2 projects)
• Introduction of Layer 3 differentiated services
  (Premium, BE, LBE)
• Instrumentation for network measurement
• JRA4 Partners
• UCL
• CNRS / UREC
• DANTE
• DFN
• GARR

Bandwidth Allocation Reservation

• Network Resources
• Layer 3 - diffserv based traffic IP Premium,
  Scavenger,
• Layer 2 VLAN, MPLS
• Layer 1 lightpaths
• Allocating network resources
• immediate
• advance
• Features
• Multiple domains
• Users as part of Virtual Organizations
• Authorization, Authentication and Accounting of
  end users
• Policy derived from SLA (input from SA2 Geant,
  NRENs)

Network Performance Monitoring

• Grid Performance closely linked to Network
  Performance
• Network Performance?, what for?
• Problem diagnostic and rectification
• Facilitate resources allocation
• Performance monitoring and SLA adherence

IPv6 Uptake

• Study of the advantages of using IPv6 in Grid
  context
• DANTE deploying IPv6 (already started)
• IPv6 is effective if deployed in all domains
• The report will cover
• Study of features of IPv6, highlighting the ones
  of interest for Grids
• Availability of IPv6 in NRENs and access networks
• EGEE internal awareness of IPv6
• Also
• Collaboration with 6NET
• Possibility of building a testbed, needs to be
  agreed

Initial Milestones Deliverables

• Bandwidth Allocation Reservation
• DJRA4.1 (M6, Sep/04) Specification of Interfaces
  (network control plane global resource
  reservation middleware)
• MJRA4.4 (M12, Mar/05) Prototype Implementation
  of bandwidth allocation and reservation service
  at specific network ingress points using static
  network configuration
• Network Performance Monitoring Diagnostic
  tools
• MJRA4.1 (M3, Jun/04) Definition of initial
  network performance metrics and composite
  measurements required
• MJRA4.2 (M6, Sep/04) Requirements and use cases
  for users, mw ops
• DJRA4.2 (M9, Dec/04) Definition of standardised
  network measurement query/response interfaces

Sub-Tasks in Progress Bandwidth Allocation and
Reservation

• DJRA4.1 (M6)
• ST-2.1.1 Analysis of Existing Interfaces and
• ST-2.1.2 Survey of Software available today
• Partners UCL/CNRS/DANTE
• In Cork

Sub-Tasks in Progress Network Performance
Monitoring

• MJRA4.1 (M3)
• ST-1.1.1 Study of Performance Standards and
• ST-1.1.2 Selection of the appropriate Metrics
• Partners CNRS/DANTE/DFN/GARR
• In Cork,
• Some documents from standard bodies listed (IETF,
  GGF)
• Need for reviewed in detail
• Pointing to previous projects as starting point
  (DataGrid, DataTAG)

11
Sub-Tasks in Progress Network Performance
Monitoring

• MJRA4.2 (M6)
• ST-1.2.1 Requirements and Use case for end
  users
• Partners UCL/CNRS
• ST-1.2.2 Requirements and Use case for
  Operations
• Partners CNRS/DFN
• In Cork,
• Identifying contact points to gather requirements
  and uses cases
• End users -gt applications -gt start discussion
  with NA4
• Operations
• Brainstorming sessions for identification of uses
  cases and impact over the network

12
Meeting JRA4 with JRA1-Integration

• We (Alberto Di Meglio) had a good overview of the
  JRA1-Integration activity
• Reviewed different options for platforms and
  compilers/libraries to use
• Identify a JRA4 contact person with
  JRA1-Integration

13
Amends to the TA

• Milestone for M3 (MJRA4.1) Definition of
  initial network performance metrics and composite
  measurements required
• Nature of the Deliverables (R Report, P
  Prototype)

14
Summary

• Plenty of discussion and brainstorming inside the
  activity
• Better understanding of the activity for the JRA4
  team
• Good discussions between JRA4 and other
  activities
• SA2 (talks about having even closer
  collaboration mailing, conf calls, f2f meetings)
• JRA1 and NA4
• Clearly agreed to work closely with projects GN1
  and GN2
• Agreed to contribute to forums such as GGF
• Still some key decisions to make for the
  products, very much related to the design and
  architecture
• Pragmatic approach in the execution of the
  activity. It is ambitious and we have to avoid
  getting lost in details. Make it simple.
• IPv6 uptake not yet started
• Overall, very positive meeting
