Discussion
The network architecture of ABC Web Design comprises of a central server at the headquarters that is linked to satellite offices as well as remote workers by a "virtual private network (VPN)". The firm employs "Transmission Control Protocol/Internet Protocol (TCP/IP)" and "Simple Mail Transfer Protocol (SMTP)" as its communication protocols.
Although the VPN is a safe and economical solution to link satellite offices and remote workers to the main server, it might not be able to cope with the traffic created by the expanding business with the remote workforce of the firm (Eridani et al., 2019). The capacity of the present network design to meet the rising demands made on it could be constrained.

Furthermore, ABC Web Design's communication methods can be obsolete and unsuitable for the demands of the business. For instance, the commonly used SMTP protocol for delivering emails is known for its security and dependability concerns (Yeh et al., 2021). Emails may be misplaced or delayed, resulting in a breakdown in client communication and harming the company's brand.
ABC Web Design may take into account a hybrid network design, which combines the VPN using a cloud-based solution, to enhance the network architecture. This would ease the strain on the VPN by enabling distant workers as well as satellite offices to connect to resources from the cloud. The cloud-based solution could be more scalable, enabling the business to manage more traffic as it expands.
The existing network design and communication protocols have been found to have issues with sluggish and unstable network service, communication breakdowns with consumers owing to lost or delayed emails, and challenges gaining access to the tools needed to complete tasks (Ahad et al., 2019). Numerous things, such as a lack of bandwidth, old technology and software, and bad network architecture, might be blamed for these issues.
We advise ABC Web Design to update its hardware and software, enhance the network's architecture, increase bandwidth, and put in place stronger and more reliable communication protocols in order to solve these issues. The following is specifically suggested (Chen et al., 2020). To accommodate the demands of satellite offices and remote workers, the network design has to be enhanced. To guarantee that all staff members have access to the tools they require for their jobs, this involves utilizing a hybrid network design that combines a VPN alongside a cloud-based solution. To guarantee that emails are sent quickly and securely, ABC Web Design should integrate more reliable and safe communication protocols, like "Transport Layer Security (TLS)" and "Internet Message Access Protocol (IMAP)".
ABC Web Design could think about introducing more dependable and secure protocols, including TLS and IMAP, to address the problems with the current communication methods. IMAP enables users to see their emails from many devices, boosting accessibility and convenience, while TLS offers secure communication across the internet and may be used to encrypt email communications (Huang et al., 2019). The efficiency and effectiveness of ABC Web Design's present network architecture as well as communication protocols may be constrained. The business may guarantee smooth and efficient operations, enhance network performance, and prevent client communication failures by improving the network architecture and employing more dependable and secure communication protocols.
