1 FIBRE-BR Meeting GENI I&M Marcelo Pinheiro

2 Agenda GENI Overview GENI User groups GENI I&M Use Cases GENI I&M Services

3 GENI Overview Run experiment (repeatability, realistics environment, virtualized management interfaces) Credentials management (Authentication, Authorization and Accountability) Privileges and roles definition Integrity control among all aggregates (in case of crash/restart)

4 GENI Overview Federation support & Trust relationship Inter-aggregate monitoring Experiment monitoring in order to avoid infrastructure misusage Debug facility (Operation and User level) Status monitoring Policy Management (i.e., cannot reserve more than 40% of any aggregate)

5 Type of users Experimenters: Users that run Internet-scale experiments in slices comprising of multiple GENI resources to address research problems of the future- Internet. Opt-In Users: Users within the GENI suite or general Internet users who participate or “opt-in” to a GENI experiment to utilize resources, applications or services that are hosted within the GENI experiment. Central (i.e., GMOC) Operators: Group that monitors the GENI facility resources and processes in order to bring consistency, reliability and repeatability to GENI’s federated infrastructure.

6 Type of Users (II) Aggregate Providers and Operators: Groups that provide a set of network or computing components to GENI experiments along with software to manage the components, and allow users to check the availability and status of the various components. Archive Providers and Operators: Groups that catalog indexes of GENI-related measurement datasets in a repository and provide tools for users to share, annotate, search and cite the measurement datasets. Researchers that use Archived Measurement Data: Users that utilize the measurement datasets provided by Archive Providers in order to test hypotheses, and promote reproducible research.

7 Experimenters Make sure all resources are reserved accordingly “Are all the resources with the performance expectations that were specified in the RSpec? For example: 2 Mbps available bandwidth connection between Nodes A and B, run a 2 Mbps UDP Iperf test so that I can check there is no packet loss.” Provide a dashboard of resource performance measurements as the experiments are run (real-time). Allow to query the status of user slice resources

8 Experimenters (II) Allow to setup up TCPdump passive measurement taps Allow to setup Netflow measurements collection Allow to setup vendor-specific measurements collection Allow to Setup up active measurement capabilities on paths x, y, z using p, q, r tools

9 Experimenters (III) Allow to Setup one-way delay active measurements Notify anomalies and forecasts of system and network performance at hops a, b, c on paths x, y, z pertaining to tools p, q, r Provide an archive of some or all of the slice resource performance measurements Provide an archive of the slice resource performance measurements

10 Experimenters (IV) Generic “I am running an experiment to deploy a novel IPTV system protocol, provide me with PSNR measurements of video quality between paths x, y, z (e.g., Evalvid tool that will need source and destination packet captures)” Provide access to the experimenter opt-in users who want to query measurement data within the experiment slice using web-service clients Provide mechanisms to share slice measurements archive with researchers and opt-in users at different levels of permissions sharing (i.e., whitelist/blacklist, sign-in, public)

11 Opt-In Users Provide the end-to-end delay and loss characteristics of the network paths Show whether the Opt-in user got all the resources (e.g., CPU, Memory, Disk space) with the performance expectations Allow the Opt-In user to query the latest status of his/her application resources so that he/she can know the reason for the poor performance

12 Central Operators Setup vendor-specific measurements collection Setup up active measurement capabilities on paths x, y, z using p, q, r tools Provide capabilities for looking at the measurements being collected via a weathermap interface (Flack) Provide an archive of some or all of the slice resource performance measurements

13 Central Operators Monitor slice behavior (Clearinghouse) Notify status of user slice resources via a dashboard with some or all of the resource performance measurements in the user slice; Keep meta-data of all the experiments Setup Netflow measurements collection

14 Aggregate Providers and Operators Have an authentication mechanism based on the privileges assigned to the different user roles (Clearinghouse) Monitor the slice behavior Notify status of the user slice resources via a dashboard Keep meta-data of all the running/expired experiments Setup Netflow measurements collection

15 Aggregate Providers and Operators Setup vendor-specific measurements collection Setup up active measurement capabilities on paths x, y, z using p, q, r tools Provide capabilities for looking at the measurements being collected via a weathermap interface (Flack) Provide an archive of some or all of the slice resource performance measurements

16 Archive Providers and Operators Publish measurement archives with suitable keywords Have an authentication mechanism based on privileges Provide policies relating to the measurement archive sharing permissions (i.e., whitelist/blacklist, sign-in, public) Allow users to use tools and transformation libraries that deal with various data formats to: share, annotate, search and cite the measurement datasets in my repositories Contribute various tools that will allow researchers using the archived measurement data to analyze and visualize their corresponding published data sets more effectively

17 Researchers that use Archived Measurement Data Search results and access to measurement archives published by the experiment researchers, aggregate providers and GMOC Share (e.g., , post on Twitter), annotate, search and cite the measurement datasets in repositories of several Archive Providers

18 Types of I&M Services Type 1: Service contained within a slice. Type 2: Common service platform plus multiple slivers dedicated to multiple experiments. Type 3: Common service with shared data provided to multiple experiments. Type 4: MDA service with a portal for sharing data

19 I&M Services – Type 1 A Type 1 I&M service is completely contained within a slice, where the slice is owned and managed by an Experimenter to instrument and measure an experiment, or by a Service Provider or an Operator to instrument and measure GENI infrastructure.

20 I&M Services – Type 2 Includes a common service platform that is assembled, configured and managed by a Service Provider plus multiple slivers that are acquired, configured and managed by multiple slice owners, e.g., Experimenters and/or Operators.

21 I&M Services – Type 3 Includes a common service that is assembled, configured and managed by a Service Provider and that provides measurement data to multiple slices, e.g., those owned by Experimenters and/or Operators.

22 I&M Services – Type 4 It is a Measurement Data Archive (MDA) service that is assembled, configured and managed by a Service Provider and that archives data for multiple slices, e.g., those owned by Experimenters and/or Operators. The MDA service includes a portal that allows a Slice Owner to access their MD and share it with others.

23 Pergunta (provocativa) Devemos e/ou podemos ter serviços de configuração de experimentos customizados (genéricos) pelos experimentadores no I&M (mesmo que seja num planejamento mais longo que o FIBRE)?
