Consider a packet of length l, which begins at source and travels over seven links to a destination. these links are connected through six routers. let di, si, and ri denote the length, propagation speed, and the transmission rate of link i, for i = 1 to 7. the processing delay at each router is d-proc. the queuing delay at each router is d-que. what is the total end-to-end delay for the packet in terms of di, si, ri (i = 1 to 7), and l?

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
