HEALTHCARE INFORMATION SERVICES TESTBED THROUGH CONTENT CENTRIC NETWORK

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

3 Introduction • Healthcare and hospital are the most complex service systems. • The trend of healthcare data usage is more collaboration. Data evolution in the Healthcare System Paper format Electronic Data (Own Formatted) Standardization Formatted (e. g. , HL 7, DICOM) Data Collaboration

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

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.

9 Information Hierarchy Hospital division Patient [Name] [Name]

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

11 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 2 GB RAM • Cisco 2960 switch • S/W • Vmware ESXi 5. 0 • Linux Ubuntu server 10. 04 • CCNx® open source project (CCNx http: //www. ccnx. org/ -0. 4. 2)

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

14 Experimental Result : Connection & Data transmission

15 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 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.

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.
