Topic 18 - Network Choice And Performance Flashcards
What are Networks?
Networks are all around us are as unique as the users who use them.
There are many factors and reasons for selecting the arious components that make up a network
What are the 10 factors affecting choice of network?
User experience
Users needs
Specifications
Connectivity
Cost
Efficiency
Compatibility
Implementation
Productivity
Security
What is User experience?
Is ease of use, performance, availability, accessibility
What does Users needs mean?
speed, reliability, way of working (fixed/mobile)
What does Specifications mean?
Manufacture, standards, functionality required
What is Connectivity?
Physical connections
for example choice of cabling (copper, fibre, DSL), and location
What is Cost?
Ongoing costs (Total Cost of Ownership, or TCO)
What does Efficiency mean?
Performance, expansion room, expected utilisation
What does Compatibility mean?
Manufacturer, standard, interoperability
What does Implementation mean?
(timescales, testing, downtime) limiting factors schedule limitations)
What is Productivity?
Is it suitable for the intended purpose
e.g. able to support speed required for video editing?
State What Security features are included?
Firewall, malware protection, intrusion detection, monitoring facilitates
What 2 things to consider about for Manufacturer? (choosing components
Manufacturer - Is there an affinity to a particular manufacturer?
What is the corporate policy?
What to consider about for Specification?
(choosing components)
Specification - What kit meets the needs and supports required features?
What 3 things to consider about for Warranty/ongoing support?
(choosing components)
Warranty/ongoing support - corporate level of support?
SLA?
Response time?
What to consider about for Adherence to standards?
(choosing components)
Adherence to standards - Will it work well with existing components?
What to consider about for Familiarity?
(choosing components)
Familiarity - Are there specific skills that in-house staff possess?
What to consider about for Infrastructure? (choosing components)
Infrastructure - What does it have to fit into
For example incorporate existing Cat6 cabling
What 4 things to consider about for Performance factors?
Available band width and connection methods
Load dash is the most likely to be 100% loading the components (how much ‘wiggle room’ is there)?
Professional level equipment SOHO equipment?
Infrastructure – is it being used on aging infrastructure
