Network Architecture Flashcards
four basic characteristics that network architects must address to meet user expectations:
Fault Tolerance
Scalability
Quality of Service (QoS)
Security
Fault Tolerance
A fault tolerant network is one that limits the number of affected devices during a failure. It is built to allow quick recovery when such a failure occurs.
Scalability
A scalable network expands quickly to support new users and applications. It does this without degrading the performance of services that are being accessed by existing users.
Quality of Service
. New applications available to users over networks, such as voice and live video transmissions, create higher expectations for the quality of the delivered services.
Network Security
two types of network security concerns: network infrastructure security and information security.
Securing the network infrastructure includes physically securing devices that provide network connectivity and preventing unauthorized access to the management software that resides on them
