Re: Bandwidth on Demand questionnaire]

["Eugene Yeh" <c00jsy00@xxxxxxxxxxx>]

Dear Victor,

   Many thanks for informing me this good news. And I apologize for the very
late response. We have lunar new year holidays the whole week last week.

   I am Eugene Yeh of NCHC (The National Center for High-performance
Computing), Taiwan. My email is cyeh@xxxxxxxxxxxx We collaborated a
videoconferencing with CANARIE last year.

   We are interested in using BoD service. But we have not identified a
particular project to use it yet. So I was wondering whether or not I should
answer your questions, even though I know some of our needs. I think I wait
until we identify a project and when we request a service from you. I'll
inform you when we identify a project to use your service. Please keep me
posted. Thanks.

Eugene

> Here is the questionnaire:
>
> 0. Are you interested in using BoD services? What is your name and
> e-mail address in case more information is needed?
>
> 1. Please describe briefly your project objectives.
>
> 2. How would you like to control the service? (automatic - through web
> service or API; manually - through web page or application)
>
> 3. Do you need any response from a reservation system? (any events
> notification, failures, start/stop messages, status reports; which way
> of communication suits you best - email, messages through reservation
> service, etc)
>
> 4. What may be BoD usage scheme in your project? (how often; how long a
> reservation may be established)
>
> 5. What may be your bandwidth requirements? (minimum and maximum
> bandwidth; granularity - 1Mbps, 10Mbps, 100Mbps, 1Gbps, etc)
>
> 6. Could you describe traffic pattern for a single reservation? (bulk
> transmission or separated bursts; packet size)
>
> 7. Could you shortly describe network resources you are already using or
> envisage to use? (Network infrastructure resources   data transport
> connection (type and speed), logical network topology (number of end
> points, single or multiple domains) Customer side equipment - router,
> Ethernet switches, PC, etc. Physical interface - GE, 10 GE, SDH, SONET,
> etc. Planned locations   Organizations, countries, continents)
>
> 8. Do you need any bandwidth usage monitoring? (through specific
> application, web page)
>
> 9. Do you consider or use applications that needs BoD service which have
> latency constraints? Please consider here also other reliability
> associated parameters. (Latency constraints - sensitivity to the one-way
> delay or the round trip time Sensitivity on discontinuous changes in
> latency - e.g. when a protected service re-routes during a network
> failure condition Reliability associated parameters - round trip time,
> loss, reordering, etc.)
>
> 10. Could you describe if any level of additional security from network
> infrastructure would be helpful for the project. (Need for additional
> security provided by BoD service   e.g. application itself does not
> provide necessary security Need for traffic separation   e.g. some level

> re-establishment decision   made by user or application Restoration time
> preferred - <50 ms; 50 ms 0.5 s; 0.5 s 5 s; 5 s 1 hr; 1 24 hrs; 1 day 1
