IPV4 is the most Commonly used version because in the IPV4 it is relevant and faster processing and Compered to IPV 6 is less in cost . • IPv4 - 32 bits • IPv6 - 128 bits A. Briefly describe the following four technologies: circuit switching, packet switching, frame relay and ATM ? 1. Circuit Switching : Circuit-switching is a network in which a physical path is obtained for and dedicated to a single connection between two end-points in the network for the duration of the connection.…

and it can forward up to 40 Megabits per second for all packet dimensions. It uses a consolidated route lookup engine, common memory and the Packet Forwarding Engine is applied in application explicit integrated circuits. Usage of ASICs encourages effectual measure of data packets through the system. Packets run over the Packet Forwarding Engine in sequence. First packets reach at a receiving PIC interface. Then the PIC permits the packets to flow to the input and output administrator on the…

RTP) Time stamping allows for the synchronization of data packets. While RTP doesn't actually provide the synchronization, it does provid the necessary information to the…

packets. This will drain the battery of the Zigbee module and can be used to disable the device [9]. The second and most overlooked attack is a physical attack on the actual Zigbee device. Zigbee devices are not very secure. They often store the network key information in plain text without encryption or password protection. Simple AT commands can often be used to retrieve this information if the device is physically accessible. All Zigbee devices in the network have access to the encryption…

Evaluating the Feasibility: Should Cities Have City-Wide Wi-Fi Many cities around the world have considered implementing a form of public city-wide free Wi-Fi, whether it is in the better interest of the city is another topic. Implementing a city-wide Wi-Fi network is a logistics nightmare, the amount of planning and men required to do such a task is impressive. If done properly, this task is an impressive feat. Some cities have managed to accomplish it, and along with the wonder and awe of…

have a MAC address. For example: a switch, a computer, and a hub would all have their own MAC address and that address is permanent to each individual device. 2. (5 points) How is TCP different from UDP? TCP – Using TCP a computer will send packets to a website and in return the…

whether or not to forward or ignore a packet. The Purpose of a Bridge are isolating networks by Mac address, manages network traffic by filtering packets and translate from one protocol to another. Hub is like a repeater. When a packet goes in one of the port, it gets duplicate inside…

knows how many packets can be safely transmitted. The congestion window is a state variable for each connection which is used by the sender to limit how much data a sender can transmit into the network before receiving an acknowledgement. This report consist of the simulation of different model of TCP transmission which demonstrates the congestion control using the variation of dynamic window size implemented by TCP (Transmission Control Protocol). Various models are considered where packet drop…

of network software? The three functions of the network software are: To make sure that the information is addressed properly. To organise information into packets (a series of messages that a file is broken down into) on the sending workstation and putting the packets back to make a file on the receiving workstation. To check that each packet reaches the designated workstation. 4. What are the…

2.5 Proposed Architectures for SDN in WSN The novel idea of exploiting OpenFlow technology to address reliability issues in sensor networks was presented by (Arif Mahmud and Rahim Rahmani, 2011) at the IEEE International Conference on Computer Science and Network Technology while the first architectural proposal was presented by (Luo et al., 2012) in the form of Software Defined Wireless Sensor Network (SD-WSN). Up until now, very limited research work is carried out in this area. Some of the…
