Notes
Reviewing Past Items
There has been no progress on certain use cases in many weeks. Those who have outstanding promises should try to get work complete by IS-WG meeting on Tuesday at the Member Meeting.
Member Meeting Prep
Martin will be extracting some of the common needs from the use cases thus far (reminder: finish your use cases this week) in anticipation for the SMM. From these use cases we will start building the requirements document.
MS: Other topic that has been hot recently (in this group and other related projects) is the need to add authority to datasets. Ideas that were tossed around:
- Signed SOAP messages (e.g. authenticate the message itself - not the data. Would be done ad-hoc service to service.
- Chain of trust (commonly applied to the data itself - IDC method)
- Hybrid methods that borrow elements from the two (signing messages and not data sets - still maintaining a chain of trust)
MS: Mentioned that some folks have concerns about the above including that we need to be able to prove the providence of the data and whom was the signer no matter where it may be passed from. Martin has the action to put some of these thoughts to paper before the Member Meeting.
Summarization Update
Chris Small talks a little about the modifications to Netflow/sFlow that IU has experimented with. Basic idea is to inject the AS number, netmask info, and netblock info back into the saved summaries. This information could be mined later.
MS: Likes the idea of trying to mine the advertisements for necessary info. Could try to find a student to work on such a project.
MP: Updates the group a little on his summarization work. Last couple of tweaks that were made to the algorithm (to give 'weight' to each of the summaries) did not work out too well. Encourages people to see the outcome on the google code page .
Marcos mentions that he will ask some questions about the Netflow/sFLow ideas on the mailing list. Also has some questions and thoughts regarding ipv6 summarization.
Member Meeting Update
Those attending from this group:
- Jeff Boote
- Martin Swany
- Aaron Brown
- Andy Lake
- Jason Zurawski
- Evangelos Chaniotakis
Some others will be in town after Tuesday.
Conclusions
Finish the use cases by Member Meeting. First draft of requirements doc to be presented at meeting.
ACTIONS:
- ALL will finish Use cases they were assigned for next week
- Martin will extract useful bits of info to start making requirements document.
- Martin will start writing down thoughts on AA and what it means to information services.
