3Human Casualty and Infection
From 16 Nov 02 to 3 Jun 03 Infected
Cases 5327 Deaths 349 Fatality 7
Political and Social Impact
- Mistrust in Central Government
- Declined confidence on global stage
- Unstable mass public
- Global Anxiety, Job less, Isolation
Economic Impact
Expected Loss Consumer Expenditure 170 billion
yuan Tourism 210 billion yuan National Bureau
of Statistics, PRCChina Centre for Economic
Research at Beijing University,
4Why the outbreak breaking China
Unmanaged case reporting Decentralize case
record Hidden reports
SUPER SPREAD
Slow acting isolation policies Mobilized
infected cases
Limited Info-communication No efficient channel
to dissimilate Central policies Localize update
on SARS treatment and diagnosis
Why the outbreak breaking China
5Underneath Problems in China
Limited coverage 40M phone user out of 1.6B
population Dominant operator own 70 of national
network Coverage concentrated in urban
area Insufficient Bandwidth PSTN low bandwidth
for voice and fax only ADSL limited upstream
data rate Main communications between
hospitals Demand on Quality of service No
guaranteed service for mission critical
communications
Telecom Infrastructure
Discarded Security Unsecured medical data
transmission over PSTN or Internet
Underneath Problems in China
6Underneath Problems in China
Limited Medical Coverage Inadequate medical
support for most rural area Decentralized
Monitoring No dedicated escalation and case
reporting scheme Undeveloped reporting channel
(Voice, fax, letter, etc)
Medical Framework
No common management platform Independent
disaster management Localize and Isolated
medical policies Overlooked risk
management Delayed report Hidden infection
status Mistreat SARS carriers
Underneath Problems in China
7Proposed Solution China Defensive Network of
Health
- Basic Concept
- Ethernet-based network
- LAN technology specified in a standard, IEEE
802.3. - Multiple Access with Collision Detection
(CSMA/CD) - High Speed - Up to 1 billion bps (Giga Ethernet)
10-Gigabit Ethernet
- Characteristics of our proposed solution
- High Speed
- High Security
- Flexible provisioning method
- Diversity
Proposed Solution CDNH
8Basic concept of CDNH
- 3-layer network in service provider network
- Core Layer
- Distributed Layer
- Access Layer
Proposed Solution CDNH
9Security
- VLAN
- No point to point leased lines are required
- Independent operations
- Fully controlled by the service provider
- Support IP, IPX, unicast, multicast and
broadcast packets
Proposed Solution CDNH
10Flexible Provisioning Method
Through 3rd ISP
No limitation of service provider's coverage
Proposed Solution CDNH
11CDNH A 5-layer Design
Proposed Solution CDNH
12Applications
- E - case
- E cure
- Data Warehouse
- IP Phone
- Video Conference
- Video Broadcasting
Proposed Solution CDNH
13Suppression of further Super-Spread
A Super-Spread Reference in Beijing
37 patient stay away from infection
Suppress the infection from 2nd generation
Infection Rate
?48
Expected outcome of CDNH
14Reduction of infectious case
Accumulated Case in Beijing
Actual
Expected Reduction
?48
Reduced Human Casualties and Infected Cases
15Shorten the infectious period
Expected curve under CDNH
Infection trend of SARS, Beijing 2003
Reduced Human Casualties and Infected Cases
16Prevent Social and Political Problems
Build up confidence internally and externally
United the public, join force against outbreak
Uphold mental health, maintain productivity
17Future Development of CDNH
- E-Government
- e.g. identity card application, land registry
and appointment booking - E-Education
- e.g. Joint-university library network, academic
discussion, - seminars and lectures
- Security
- e.g. crime monitoring and information exchange
- Live Monitoring of Road Traffic Condition
- e.g. Live webcast of road traffic condition
- Weather Monitoring Forecasting
- e.g. View the live local weather by video format
Future Development of CDNH
18Conclusions
Through this project, we learnt. How to use
telecom products to improve our living
environment How to design a network from a
carriers point of view How to expand the uses
of telecom products
Past, Great Wall Today, China Defensive
Network of Health
Conclusion
