Reasons for choosing SONET ring as the packet switched service while redesigning a WAN
The reason for choosing the SONET ring is because it has the ability to carry other kinds of traffic like Ethernet, ATM and IP. SONET basically refers to the underline technology that conveys information through the WAN. As such, SONET is also selected because it utilizes fiber optic in a series of rings that are interlinked all through the SONET network. They are usually 2 rings for each connection. Data flows in one direction on one ring, and another direction on another ring (Dean, 2019). Gadgets join both rings together and separate rings as well. If there was a breakage in one ring, data can be routed through the other ring. This way, there is a redundancy of service all through WAN. Other reasons for choosing SONET ring can be attributed to the fact that it has better network reliability, better connectivity, lower equipment investment and is highly flexible architecture meaning that it is able to carry multiple applications (Kenneth, Mansfield & Antonakos, 2019).
Design considerations while redesigning a wired LAN to include Wireless LAN
One of the design challenges pertains to identifying challenges associated with the redesign. These could be physical challenges like thick concrete walls and ceiling heights. There could also be possible physical challenges to the Radio Frequency environment. It is also important to put the number of wireless devices into consideration. The number of users and user gadgets affects the number of access points required for the wireless LAN (Roshan & Leary, 2014). Therefore, as more gadgets link to the network and augment capacity requirements, the need for extra access points also augment. Performance expectations should also be considered. This entails establishing and defining the expectations of the customer for performance. Wireless LAN’s performance is based on the number of infrastructure gadgets installed, encompassing access points and bridges.
