Computer Dynamics is a microcomputer software development company that has 300-computer network. The company is located in three adjacent five-story buildings in an office park, with about 100 computers in each building. The current network is a poorly designed mix of Ethernet and token ring (Ethernet in two buildings and token ring in the other). The networks in all three buildings are heavily overloaded, and the company anticipates significant growth in network traffic. There is currently no network connection among the buildings, but this is one objective in building the new network. Describe the network you would recommend and how it would be configured with the goal of building a new network that will support the company's needs for the next 3 years with few additional investments. Be sure to include the devices and type of network circuits you would use. You will need to make some assumptions, so be sure to document your assumptions and explain why you have designed the network in this way.
Assume that airliner carries 10,000 kg of those floppies at speed of 1000 km/h over distance of 5000 km. Compute data transmission rate in bits per second of this system?
A typical signal sequence in synchronous connection contains significant amount of information in addition to just intended message or data.
What is the system development life cycle and what are the best ways to bring social networking to life within this cycle?
Research network address translation (NAT). While conducting your research, consider purpose of NAT, compatibility with IPv6, and functions of automatic IP assignment and automatic name resolution.
What occurs if office in Baton Rouge, Louisiana, also should be connected to both Memphis and Laramie at a rate of 512 kbps? Which solution is cheaper now?
Assume that N Ethernet stations, all trying to send at same time, need N/2 slot times to sort out who transmits next. Describe available bandwidth as function of N.
Packet switch receives a packet and determines outbound link to which packet should be forwarded. Determine the queuing delay for packet? Show work.
Consider transferring an enormous file of L bytes. What is the maximum value of L such that TCP sequence numbers are not exhausted? Give proper justification?
Suppose there is a 10 Mbps microwave link between a geostationary satellite and its base station on earth. What is the propagation delay of the link?
Consider transferring a large file of L bytes from Host A to Host B. Assume a MSS of 1460 bytes. What is the maximum value of L such that the TCP sequence numbers are not exhausted?
Assuming that switches user store-and-forward packet switching, what is the total end-to-end delay to send a packet of length L? (Ignore queuing, propagation delay, and processing delay.)
Discuss the role of Technology in improving the relationship building process Do you think that the setting of a PR department may be helpful for the ISP provider? Why?
