Master/master replication. However, both nodes arenot used at the same time. Replication keeps allnodes as close to being up to date as possible(although the asynchronous nature of the replicationmeans a fully consistent state is not possible).Connections to the database only happen through aPacemaker virtual IP, ensuring that most problemsthat occur with master-master replication can beavoided.

Not heavily considered. Onceload on the MySQL serverincreases enough thatscalability needs to beconsidered, multiple mastersor a master/slave setup canbe used.

Campus-Scale OpenFlow Testbed

Possibility• SDN/NFV Labs to Research Center

• SDN/NFV Testbed antar campus di Indonesia

SDN/NFV Labs• Laboratorium SDN/NFV

• Proof of concept for SDN/NFV application

• Start from the labs, experiment across campus

• Expanding to SDN/NFV Research Center

SDN/NFV Test Bed• Experimental test bed across campus

• Extending test bed between campus/research group

• Leveraging Indonesia Research Education Network

What’s Next: Collaboration

But don’t forget the human• Pengembangan human resource

• SDN/NFV community in ITB

• Activity: discussion, small labs, seminar

• Next step: meetup, small workshop

• Extending to: seminar, workshop, training

SDNRG ITB• SDN Research Group at ITB

• http://sdnrg.itb.ac.id

• sdnrg@itb.ac.id

• twitter.com/sdnrgitb

• facebook.com/sdnrgitb

• Special Interest Groups on Networking and Connected Services (e.g. OpenStack, Internet of Thing)

But why?

• SDN & Cloud Computing is multidiscipline topics

• No entities can understand it all completely

• Academics, Operators & Vendors needs each others:

• Academics need real use case for their research

• Operators need help for their problems

• Vendors need customers to propose their solutions

SDNRG ITB can bridge the gaps

• Academic can get real use case from practitioners

• Networkers can get help understanding SDN tech

• Vendors can promote SDN tech to educated community

After the gaps is small, whats next?

• Educated researchers can build SDN tech solutions for practitioners that fit to the real use case

• Educated networkers can architect better SDN solutions that leads to better network, with help from researchers & vendors

• Educated vendors can propose SDN solutions to the right customers

The Message• Saya tunjukkan bagaimana sebuah perguruan tinggi

teknologi membuat jaringan dalam kampus menjadi platform riset teknologi SDN/NFV tanpa mengganggu jaringan production

Let’s make it happen!
