Table 2–4 Quality-of-Service Requirements for the Reference Configuration
Service Quality |
Requirements |
---|---|
Performance |
Response time under two seconds for default portal channels at peak load levels. |
Availability |
Service availability with both user session availability and application session state availability. No single points of failure. |
Security |
Protected services in separate network subnets. Firewall protection for Internet access and for portal service subnet zone. Encrypted Internet transport over SSL. |
Scalability |
