NDN Testbed Status Update March 2017

John DeHart Washington University jdd@wustl.edu

NDN Testbed

 Shared resource for running NDN experim ents  Each node runs an NDN softw are router:

» nfd : NDN Forw arding Daem on » NLSR : NDN Routing Daem on

• Recently updated to do Hyperbolic Routing

» Other assorted NDN daem ons

 Participating sites:

» Dedicate a m achine ( real or virtual) to host a node » Designate a person as local operator for rare m anual intervention and for site-based certificate approval

 Managed by NDN team at W ashington U.  Usable by All

» Site-based certificates » Netw ork guest certs » Many sites support local guest certs

W hat happens next?

» A questionnaire to fill out w ill be em ailed to you » Request is review ed by an NDN project com m ittee » W hen approved w e w ork w ith you to install and connect your node.

Status Monitoring Sites

 Node and Prefix Status

 Bandw idth » http:/ / ndnm ap.arl.w ustl.edu/

Routing Status

Cacti graphs

» http:/ / ndndem o.arl.w ustl.edu/ cacti/ » Expanded, but continues to be a w ork in progress » Data collected through NDN I nterest/ Data packets. » Monitors things like:

• Load average, / and / boot disk usage
• NFD process size, uptim e, PI T counter, Nam eTree counter
• Etc...

» User: guest » PW : ndnTest » Exam ples on next slide…

Management Change: Ansible

 Previous Managem ent

» Via git, ssh and lots of hands-on updates.

 New Schem e: Ansible

» https:/ / w w w .ansible.com / » Managem ent, Provisioning and Deploym ent engine » One point of control

• Uses ssh to connect to rem ote nodes.

» Playbook for m aintaining NDN Testbed

• Defines tasks:

– I nstall packages and daem ons – Configure – Start/ Restart

» Each node has a defined set of variables

• Used as param eters to Tem plates to generate conf files

Coming Soon: Expansion into Amazon AWS

AW S AMI for NDN gatew ay node and client.

» Develop for use across range of AW S instance sizes.

Maintain 1 NDN GW in each of 1 2 regions

» Regional gatew ay nodes m aintained via Ansible

Develop Ansible playbook for

» Deploying NDN clients in AW S » Deploying NDN GW s in AW S

All Ansible playbooks for AW S and all AW S

AMI s to be m ade available to the NDN com m unity
