HEALTHCARE INFORMATION SERVICES TESTBED THROUGH CONTENT CENTRIC NETWORK: A PROTOTYPE

Advisor: Asst.Prof.Dr.Panjai TantatsanawongPresented by: Prasertsak U-Aroon.Department of Computing Silpakorn University, Thailand.

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

2

Introduction• Healthcare and hospital are the most complex service systems.

• The trend of healthcare data usage is more collaboration.

Data evolution in theHealthcare System

Data Collaboration

3

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

4

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)

5

• 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

Introduction : CCN networking

CCN (Content-Centric Network) - simplified to use, reliability, and flexibility to use anytime and anywhere

6

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

11

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)

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

13

Experimental Result : Connection & Data transmission

14

Experimental Result : Number of node• The number of CCN router on the network does not

significantly affect the transmission

15

Experimental Result : Concurrent data usage

• Comparison of FTP on IP networking and data transmission over CCN network

16

Content size

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.

17

Future work• Integrate the real world application of Healthcare Information

Services into the Content-Centric Network. • More investigate in security of patient’s data.
