In the previous upgrade five years ago, the school administration chose cabling with a view to make subsequent upgrades to faster networking technology, simpler and more cost effective.
The majority of users in the current network are desktop users; the desktops have Gigabit network interfaces. The current network cabling is Category 6 Twisted Pair Ethernet cabling, connecting to Ethernet network switches. These switches are capable of Gigabit connectivity. Cat6 Ethernet cable is commonly used as it offers stability. The choice of Cat6 Twisted Pair Ethernet intended to run at Gigabit speeds meant that the cabling, network cards and network cards and network switches needed to be aligned with this choice of cabling(DeSanti--Cisco …show more content…
It terminates the internet connection in each office. There is a site to site VPN tunnel between the two devices, connected over the internet. The SonicWALL is the default gateway (router) in each office that routes traffic either to the internet or between offices and acts as the firewall between LAN and WAN. This device also enables VPN tunnels for telecommuters (Implementation Consultants) to connect to the office as necessary. In both the current and proposed network; the logical typology is a star as describe below:

Logical topology: Star (switched Ethernet)

This is because the design is a switched based Ethernet approach. The switch at the centre manages (is connected to) the sets of separate point to point circuits (Fitzgerald et al. 2012 p208). The advantage withthis approach is that the circuit connecting the switch and the device does not need to be shared. Ideally this will allow the circuit to realise its full potential. In both the current and proposed network the physical topology is a Star.
This topology accurately represents the current and proposed network because the way the network is physically installed is replicated below, that is; each device is connected to a switch (FitzGerald and Dennis, 2005). Servers Domain Controller (runs DHCP and DNS functions) all

...ASSIGNMENT-3 NETWORK ARCHITECTURE-1 Submitted by: YENUGU SATHYADHARI 16190296 Compare GBN, SR and TCP(no delayed ACK).Assume that the timeout values for all three protocols are sufficiently long such that 7 consecutive data segments and their corresponding ACKs can be received( if not lost in the channel) by the receiving host(host B) and the sending host (host A) respectively. Suppose Host A sends 7 data segments to Host B, and the 2nd segment (sent from A) is lost. In the end, all 7 segments have been correctly received by Host B. How many segments has Host A sent in total and how many ACKs has Host B sent in total? What are their sequence numbers? Answer this question for all the 3 protocols? Sol: Given 3 protocols...
