Answer to Question #174417 in Algorithms for Jean Claude

Question

Question 3

(a) Using the AIT Lemass as an example, discuss practically the Quality of Service (QoS) levels in the areas that are measured when determining 3 the performance of a system. If any of the areas measured has a poor quality of service, discuss what could be done to improve upon its quality of service.

(b) Discuss practically the server form factor(s) you would consider for AIT and justify your choice with reasons

(c) Using the AIT Internet provision for lectures to be streamed online as a case study, discuss the kind(s) of challenge(s) faced by lecturers (e.g IT101) using the Internet service(s) provided by the school for the online streaming and its impact on students (both on campus and at home/hostel). Discuss what you think could be done to resolve such challenge(s).. 

Answer 1

a) Quality of service (QoS) is the description or measurement of the overall performance of a service, such as a telephony or computer network or a cloud computing service, particularly the performance seen by the users of the network. To quantitatively measure quality of service, several related aspects of the network service are often considered, such as packet loss, bit rate, throughput, transmission delay, availability, jitter, etc.

In the field of computer networking and other packet-switched telecommunication networks, quality of service refers to traffic prioritization and resource reservation control mechanisms rather than the achieved service quality. Quality of service is the ability to provide different priorities to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow.

b) I would consider for AIT Blade servers: Blade servers are designed to save even more space than rack-mount servers. A blade server is a server on a single card that can be mounted alongside other blade servers in a blade chassis, which itself fits into a standard 19-inch equipment rack. A typical blade chassis holds six or more servers, depending on the manufacturer.

One of the key benefits of blade servers is that you don’t need a separate power supply for each server. Instead, the blade enclosure provides power for all its blade servers. Some blade server systems provide rack-mounted power supplies that can serve several blade enclosures mounted in a single rack.

c) Students encounter technical difficulties which is the main block of online training limitation. There are operating systems, browser's, smartphones and network connectivity problems.

To resolve such challenges: update operating, systems, install modern network equipment (routers, switches, etc.), update passwords to access network.
