Question $2.$ The bisection width is the minimum number of links that must be

removed to partition the network into two equal halves $($or two sets that differ by at most

one node in size$).$ The bisection bandwidth is the minimum sum of bandwidths of these

links among all possible partitionings. What is the bisection bandwidth of the following

$5$x$5$ mesh, assuming the bandwidth of every link is $1$Gb per second? A planar $2$D

mesh is just like a $2$D toroidal mesh, except that it doesn$$t have the $$wraparound$$ links.

$($a$)5$Gb$/$s $($b$)6$Gb$/$s $($c$)7$Gb$/$s $($d$)8$Gb$/$s $($e$)$ None of them is correc
