1. The achievement of a client-server order is strongly influenced by couple elder network characteristics: the bandwidth of the network (that is, how multifarious fragments/sec it can rapture) and the latency (that is, how multifarious prevents it interests restraint the pristine fragment to acquire from the client to the server). Produce an pattern of a network that exhibits exalted bandwidth not attributable attributable attributable attributable attributable attributable attributable attributablewithstanding also exalted latency. Then produce an pattern of undivided that has twain abated bandwidth and abated latency.
2. What are couple reasons restraint using layered protocols? What is undivided practicable hindrance of using layered protocols?
3. What is the ocean disagreement among TCP and UDP?
4. An effigy is 1600 × 1200 pixels with 3 bytes/pixel. Assume the effigy is uncompressed. How desire does it interest to cast it aggravate a 56-kbps modem document? Aggravate a 1-Mbps cable modem?
5. Calculate the end-to-end transit term restraint a packet restraint twain GEO (altitude: 35,800 km), MEO (altitude: 18,000 km) and LEO (altitude: 750 km) satellites.
6. Three packet-switching networks each comprise n nodes. The pristine network has a triton topology with a accessible switch, the prevent is a (bidirectional) ring, and the third is amply interconnected, with a wire from complete node to complete other node. What are the best-, average-, and worst-case transmission paths in hops?
