3. WIS DATA-COMMUNICATIONS FUNCTIONS AND SERVICES (for weather, water, climate and related data and products)
DAR
Data pull
Data push
WIS
IGDDS
GTS
WIS/GTS: for time and operation-critical data & products
WIS/IGDDS: for space-based data & products
WIS/DAR: data discovery, access and retrieval
Data push: routine distribution of data & products
Data pull: access to and retrieval of data & products

4. Brings new challenges to ET-CTS
Paradigm Shift
Focus moves from “communications centric” to “information management centric”
Brings new challenges to ET-CTS
Information management is in other ET
ET-CTS recognizes need for closer relationship for development of future material

5. Definitions as per ET-CTS
Telecommunication Networks
GTS Network
IMTN
Internet
Satellite dissemination (and IGDDS)
Time Critical and Operational Critical
Globally
Bilaterally

6. Exchanges between functional elements
Obvious requirements at this time

7. GISC Synchronization Telecommunication Network
Data Communication Technique
MPLS
Speed
Presumed high
Need clarification of traffic volumes and latency requirements
High availability
Security
One of several protocols (needs further investigation)
SIMDAT
Peer to peer protocol
Other
Need GISC sync only picture

8. TCOC Routine Collection
Telecommunication Network
Data Communication Technique
GTS Network
Speed
Presumed low to medium
Assumed to be current GTS traffic
Network priority mechanism
CoS
Separate network
Use existing GTS techniques
Build priority mechanism for new 2 mins delivery requirement of priority traffic
Clarify which traffic is priority
Define recommendation (specification) for switches
Need TCOC only picture

9. Adhoc DAR Telecommunication Network Data Communication Technique
Internet
Speed
Presumed medium to high
Uneven usage
Specify considered protocols
What are they?
HTTP based
DCPC holder of information
GISC can answer as well, but needs to redirect to DCPC for actual data delivery
Can they be used for queries on TCOC 24h archives?
Need Adhoc DAR only picture

10. GISC to DCPC Catalog Harvesting
Telecommunication Network
Data Communication Technique
MPLS
Speed
Presumed medium
Need clarification of traffic volumes and latency requirements
High availability
Specify considered protocols
What are they?
ET-WISC responsibility?
Need Adhoc DAR only picture

11. Procedures to be defined
User Registration
Required at all levels
Although data access often open to anonymous users, registration required for bandwidth management (especially in full mesh networks such as MPLS)
Procedures to be defined
Registration may be required for network management and data management
Requires an application
Consider SIMDAT authentication method
Anonymous service would be offered only if no service level guarantees
What can ET-CTS do to advance:
Procedures for managing of access rights
identification of users
Or do we state that this is application level responsibility?

12. Other General considerations
Short time frame in WIS plan
In order to realize technical standards in short time, needs resources to be more focused
12-15 people 1 week/2 years not enough
Compounded by parallel work issues
Parallel development such as “Development of new standards and guidelines” versus “Pilot projects (e.g. RA VI VGISC ITT)”
Need for more collaboration
Sharing of specifications
Defining essential specifications
Defining core standards
Wherever there is a choice of techniques or protocols, establish criteria for selecting technique
