Why is the bandwidth of the pre-established reserved link divided on multiple new connections?
I am reading Kurose Computer Networking book 8e, on page number 57, under 1.3.2 Circuit Switching Because it link has $4$ circuits, for each link used by the end-to-end ... in circuit switching affect the network's scalability compared to packet switching, where bandwidth is shared dynamically?

GO Classes Test Series 2024 | Mock GATE | Test 12 | Question: 35
Consider two TCP connections $\text{A}$ and $\text{B}:$ The RTT for connection $\text{A}$ is $100$ ms while the RTT for connection $\text{B}$ is $200$ ms. Let $\textsf{ssthresh}$ denote the threshold at which the congestion ... end up sending $65$ more packets than connection $\text{A}$ in interval $[\text{T}, \text{T}+1]$ seconds.

U = set-up time for circuit switch (seconds) Y = transmission delay per link (seconds) (also called “transfer delay”) L = message length (bits) >0 R = transmission rate (bits per second) >0 (also called “placement rate”) H = header size (bits) =>0 P = packet size (bits) >H (note that this is the total packet size, i.e. header + data) X = decision time per packet (also called “packet routing delay”) 1. If L=1000, Y=1, R=4000 and U=1, choose a value of X. What is the total transmission time in the circuit switch network and packet switched network? Consider P=125 and H=25. (3 marks)
