Answer

Introduction
With this project, the three tasks that will be performed are the illustration of the socio-technical concept, SNMP v3 configuration, and Wireshark capture. In order to discuss the illustration of socio-technical system design, both the social and technical systems will be discussed and software engineering will be considered as an example. In the second task, a network topology has been designed by using 4 routers and 4 switches, and the RIP 2 protocol has been introduced. Then the routers have been configured with SNMP v3 and the SNMP tasks have been performed on PCs using the MIB browser. However, the data packet has been captured using the Wireshark tool in task three.

Task 1
STSD (Socio-technical system design) approach is a design technique that takes into account physical, social, and institutional factors as well as technological elements in the design of organizational structures. It has a lengthy history and is designed to guarantee that a system's technological and functional characteristics are taken into account simultaneously. The use of these methodologies results in a greater knowledge of how personal, social, and institutional aspects influence, how the process is completed and technological systems are used. This knowledge may help with the creation of business structures, business operations, and hardware resources [4]. The socio-technical system includes various functions that are social system, technical system, system integration, and managing the system.In order to evaluate the socio-technical system, all the above functions need to be illustrated. Most business organizations are developing their business operations following the socio-technical systems.

Therefore, it is important to develop the socio-technical architecture for the business organizations which must consider the two design components that are social system and technical system. In this report, software engineering has been selected as an example of a socio-technical system. Both the social and technical aspects are considered in software engineering. Most of the software applications are developed to meet the requirements of society and some specific organizations. There are several factors that can be considered to develop the software engineering operations that can be identified as peoples, hardware, software, laws & regulations, and data design. The use of technical resources and their usages can be enhanced in the software development process. Here, both the social and technical aspects have been illustrated to describe the socio-technical system design.

Social system:The social systems can be improved by considering the requirements of the users.Business organizations are developing software applications considering the latest social trends and market demands.Persons are the first priority to identify the user requirements from the system developed [5]. Here, the user feedback is collected from the existing system and the development process can be initiated following the user requirements.Various social issues can also be mitigated by introducing new features into the software. The smart alarm is an appropriate example that responds against critical situations and the system is developed considering emergency situations. Users share the login credentials on the software interface and most software stores the personal details of the users. Here, data and information protection is a social consideration that must be ensured by the developers. However, the goal and On the other, various rules and regulations are also associated with software engineering services. Here, the process of software development is also responsible for protecting user’s privacy and sensitive information from unauthorized users. Therefore, the developers must consider the ethical considerations to develop a system [6]. The socio-technical system is also restricted by a few laws and regulations that must be followed by the developers. Data and information protection is a major aspect that must be followed by the software engineers and various protective features are enabled into the system developed.

Technical system:
The technical system refers to the technical requirements that are required to develop the software application and other business operations. Various factors need to be considered to identify the technical specifications of the business operation. Both the hardware and software components are accounted for in the technical system.

On the other hand, the data sets are also designed to fulfil the technical requirements of the system. Data sets are protected by using a protective measures like passwords and authentication protocols. Various workstations, frameworks, connecting devices, and other peripherals are associated with the socio-technical system [7]. Without adopting the technical components, no software system can be developed. However, the technical components are also implemented to check the system quality and monitor the entire operational process. The socio-technical system can be implemented into the software engineering process by considering both the social and technical aspects.

However, the socio-technical system is mainly developed to utilize the technical resources in the system development. The socio-technical aspects are also considered to improve the user experience in a particular field. The operational cost of the system could be increased to execute the socio-technical aspects, but, the performance potential can be enhanced by introducing the socio-technical system design.

The above figure illustrates the through graph of the captured packet files. Here, the y-axis represents the segment length that is calculated in bytes while the x-axis represents the time that is calculated in second [3]. The above graph mainly shows how much data is transferred from the server in per second interval.

Time Sequence (Stevens) graph

The above figure illustrates the time vs sequence (Stevens) graph of the captured packets. Here, the sequence number is increases with the increase of time.

Network Topology in supply chain management

The above figure illustrates the time vs sequence (tcptrace) graph of the captured packets. Both the time sequence diagram mainly shows a data stream over time [2]. These two graphs are very useful to see that the traffic is moving without interruption, long delays, or packet loss. Here, for every 1 byte of TCP data delivered, the sequence number rises by 1.

Conclusion
Three tasks have been completed as part of this project on networking assignment that includes depiction of a socio-technical concept, SNMP v3 configuration, and Wireshark capture. Both social and technological systems have been examined, with software engineering as an example, in order to explain the illustration of socio-technical system design. In the second challenge, a network architecture was created utilising four routers and four switches, as well as the RIP 2 protocol. The routers were then configured with SNMP v3 and SNMP operations were done using MIB browser on PCs. However, in task three, the data packet was collected using the Wireshark programme.
