1 HEALTHCARE INFORMATION SERVICES TESTBED THROUGH CONTENT CENTRIC NETWORK: A PROTOTYPE Advisor: Asst.Prof.Dr.Panjai Tantatsanawong Presented by: Prasertsak U-Aroon. Department of Computing Silpakorn University, Thailand.

2 Outline Introduction Content-Centric Networking concept A Prototype of CCN Experiments Conclusions 2

3 Introduction Healthcare and hospital are the most complex service systems. The trend of healthcare data usage is more collaboration. Paper format Electronic Data (Own Formatted) Standardization Formatted (e.g., HL7, DICOM) Data evolution in the Healthcare System Data Collaboration 3

4 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

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) 5

6 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

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. 7

9 Information Hierarchy 9

10 Name Convention & Discovery Unique for reference and easy to manage. [protocol]:/[group-name][hospital]/[division]/[domain]/[personal-id]/[data] [protocol]:/[group- name]/[hospital]/[discovery]/[patient-id]/[data] Should well known for the requestor 10 ccnx:/medical/hospital-1/division-1/xray/patient-id/dataxxx ccnx:/medical/hospital-1/discovery/patient-id/dataxxx

11 Prototyping of medical network over CCN Hub and spoke model 11

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 CCNx® open source project (CCNx-0.4.2) 12

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 13

14 Experimental Result : Connection & Data transmission 14

15 Experimental Result : Number of node The number of CCN router on the network does not significantly affect the transmission 15

16 Experimental Result : Concurrent data usage Comparison of FTP on IP networking and data transmission over CCN network 16 Content size

17 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

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. 18
