Here are the questions to which I need an answer and a comprehensive explanation within the next 48 hours.
Question 1 : Consider a packet-by-packet fair
queueing system with three logical buffers and with service rate of one unit/second.
Show the sequence of transmissions for this system for the following packet arrival
pattern. Buffer 1: arrival at time t = 0, length 2; arrival at t = 4, length 1. Buffer 2:
arrival at time t = 1, length 3; arrival at t = 2, length 1. Buffer 3: arrival at time t = 3,
length 5. You need to find out the finish tag, order of transmission and actual
packet completion times for each packet arrival.
Question 2 : Consider a user that can be in several
places (home networks) at different times. Suppose that the home networks of a user
contain registration servers where users send updates of their location at a given time.
[url removed, login to view] how a client process in a given end system can find the
location of a given user to establish a connection, for example, Internet
telephone, at a given point in time.
[url removed, login to view] that proxy servers are available, whose function is to redirect
location requests to another server that has more precise location information
about the callee. For example, a university might have such a server, which
redirects requests for PERSON-X-EMAIL to departmental servers. Explain how a
location request for PERSON-Y-EMAIL might be redirected to PERSON-Y-ALTERNATE-EMAIL
Question 3 :
[url removed, login to view] does RTSP differ from HTTP (a) in maintaining client state
information; (b) in terms of in-band, out-of-band traffic?
[url removed, login to view] RTP RFC and find out how to calculate the inter-arrival
time jitter in the RTCP reception report.
Question 4 : Two hosts want to communicate with each other. Each host is
protected by a firewall that filter packets based on packet header. Explain the rationale
for having an AH tunnel between gateways and using ESP in transport mode between
the two hosts.
Question 5 : The CEO of a medium size company noticed the emerging
market of using Internet phone. As chief information officer in the company, you are
asked to investigate and write a report on using Internet phone and the company’s
existing LAN to replace the company’s PBX. Incorporate feasible financial projects and budget as justifications and decisions for new systems.
