What happens when the packets sent from a computer (at the application layer) reach various network nodes – local computers, remote computers, local attached routers/switches, remote routers/switches, hubs, etc.? Please discuss what network nodes of different types know about the application file being transmitted (based on what information is provided in the header at the OSI layer at which that node operates) at each level of reassembly (i.e., viewing the frame packet only, reassembling frame packets to recreate the IP...

Determine which layer(s) of the seven layers of the OSI model has (have) the following functions. List all the layers if more than one layer have the function, e.g. PL (Physical Layer), DL (Data Link Layer), NL (Network Layer), TL (Transport Layer), & AL (Application Layer – OSI layers 5 - 7). (10 points – 1 points for each sub-question) modulation flow controls error detection & error controls multiplexing collision detection addressing end-to-end network packet delivery connection-oriented or connectionless segmentation...

Consider a packet switching network. Packets from origin host travel over H hops to reach the destination host. Supppose that the origin host wants to transmit a message that is M bits long. The bit rate of all links is C (bits/sec), and the propoagation delay over every link is D seconds. The message will be broken into packets. Suppose that each packet has a constant overhead of V bits. Let L be the fixed payload of each packet. Thus,...

A 1198 byte fle needs to be transmitted using the following packet switching network with the data rate on each link R 17 kbps. Assume that the packets are transmitted one after another without waiting for any acknowledgements from the receiver. Once whole packets are received at the intermediate router they are transmitted immediately on the outgoing link. Assume that this network use a packet size of 101 bytes, of which 20 bytes are headers. How many packets are required...

Which of the fallowing characteristics of a data network is never a correct of a packet-switched network? A. A transmitted packet contains source and destination address coding, information, and error control bits. B. Individual packets of a long message can be routed under different paths by the switching exchange equipment. C. The address coding is transparent to a user d. A transmitted packet contains only information bits

Problems 1. [40 pointsl Consider a three layer protocol in which Layer 3 encapsulates Layer 2 and Layer 2 encapsulates Layer 1. Assume minimalist headers with fixed length packets. Assume the following characteristics of the layers: Layer 1, 6 octet address length, 512 octet payload; Layer 2, 4 octet address length , 256 octet payload; Layer 3, 8 octet address length, 1024 octet payload. Note that in the minimalist header arrangement no error detection or correction will be used; however,...

After traversing a wireless error filled channel packets arrive at a network node according a Poisson Process with rate λ . These packets could have corrupted bits due to the wireless channel which has a bit error probability p . A packet is said to arrive at the node successfully if no bits are in error. The number of bits in a given packet is Poisson distributed with mean μ . Assume that packets are not retransmitted. Find the rate...
