Unformatted text preview: Segmentation fault when you try to access a portion of memory when youre not allowed to. Not allow to touch other ppls process. instantaneous throughput at time t is w(t)/RTT, almost assuming RTT is infinitesimal If TCP is working the window size can normally increase by one full size packet for every RTT. MTU- maximum transmission unit, size of the max packet of the network TCP: When theres a loss the window size goes to 1/2, actually goes to 0 but exponentially increases so say its What determines your throughput when you do a file transfer. Function of throughput Can say there is some average window size W T=avg throughput = W / RTT Rate at which w increases = rate at which W decreases MTU/RTT rate at which it increases = (W / 2 ) x (T/MTU) x p = (W /2) * (W / RTT) *(1/MTU)*p W = sqrt(2/p) T=(MTU/RTT) * sqrt(2/p)...
