Outline
• Introduction
• Content-Centric Networking concept
• A Prototype of CCN
• Experiments
• Conclusions

Introduction
• Healthcare and hospital are the most complex service
systems.
• The trend of healthcare data usage is more collaboration.

Introduction : Healthcare Communities
• Medical staff working together to treat the patients
• Healthcare services should not be limited by network
infrastructure
• Patients should receive the best services in anywhere
5
Introduction : Network Infrastructure
• A huge of data are exchanged
on distributed system over the
medical cloud
• Give more bandwidth for the data
transmission
• dedicated networking
• Scheduling control
DCN (Dynamic Circuit Network)
6
Introduction : CCN networking
• DCN – Dynamic Circuit Network
• Need specific devices to support the dedicated mechanism
• Need professional to support and complexity for maintenance
• DCN – Difficult to support mobility services
• CCN – New approach for networking
CCN (Content-Centric Network) - simplified to use, reliability, and
flexibility to use anytime and anywhere
7
Content-Centric Network concept
• Content-centric networking (CCN) is an alternative approach to
the data approach on the network rather than the location
approach, based on concept of what rather than where.

Prototyping of medical network over CCN
• Hub and spoke model
12
Accessories of network prototype
• Hub and spoke model
• 1 core node
• 2 sub-networks
• 3 end-nodes
• H/W
• PC – Dual-Core CPU 2.8 GHz with
2GB RAM
• Cisco 2960 switch
• S/W
• Vmware ESXi 5.0
• Linux Ubuntu server 10.04
• CCNx® open source project
(CCNx-0.4.2) http://www.ccnx.org/
13
Testing topics & Testing Diagram
• Testing topics over the
prototype
• Connection (by ccnchat)
• Data transmission (by
ccnputfile/ccngetfile)
• Number of CCN node on the
network affect the
transmission time
• Simple performance
comparison between FTP
and CCNx protocol
Use “medical” as a prefix name of the content

Experimental Result : Number of node
• The number of CCN router on the network does not
significantly affect the transmission
16
Experimental Result : Concurrent data usage
• Comparison of FTP on IP networking and data transmission
over CCN network

Conclusions
• A distributed location and multiple site accessibility of data in
•
•
•
•
healthcare services are supported through the CCN
infrastructure.
CCN suitable to implement and less time consuming to
develop the system.
The system administrator is easier to manage and classify the
data.
The patients have the opportunity to receive better services in
anytime and anywhere.
The healthcare communities have a more collaboration.
18
Future work
• Integrate the real world application of Healthcare Information
Services into the Content-Centric Network.
• More investigate in security of patient’s data.
