Known as the "Twin City" and the city for arts and innovation, Winston Salem continues to attract many people within its city limits and surrounding areas. The city has even made appearances on top ten lists of cities to live in throughout America. With such a great reputation, it's no surprise that Winston Salem is one of the largest cities within the state of North Carolina. As many people continue to move in, internet providers in Winston Salem have increased as well. This is good news for anyone

Transmission Media Cables & Media Selection etc In order to provide a network infrastructure to over 600 users on the TaxiPixi network infrastructure, Fiber optic cabling system will be implemented in the LAN design because it is one of the best transmission media options. Fiber optic cables will be installed and configured on the physical star network topology spread throughout the 600 user network infrastructure. The main equipment that will be used during the implementation of the physical star

lab was to set up a basic network which includes a Linux server and a Pfsense router. The basics were implemented so that the following labs can build off of the original architecture in order for there to be a base topology to work off of. First a router was installed with Pfsense and both is NIC’s were configured. One NIC was configured to connect to the local area network and the other was configured to connect to RIT’s servers in order to connect the virtual network to the World Wide Web, and

Statistical Analysis of Network Traffic The use of statistical features of network traffic for detection of DDoS attacks had made good contributions. They can also be used for trace back schemes. The use of Regression Analysis where strength of DDoS attack is estimated and compared with actual strength. The comparison results were promising, indicating that this method is applicable for DDoS strength evaluation in router or a separate unit communicating with the router. Another type of approach named

Figure 1 23 shows the proposed network arrangement between the nodes and their associated roles within the ZigBee network. The roles within the network are in accordance with the functionalities and requirements of each type of device as specified by the ZigBee networking standard. The PC/base station has been appointed the role of coordinator since its functions include hosting the SLAM and GUI processes. Therefore the PC/base station is required to transmit GUI data commands and receive updated

Link Quality Based Hierarchical Routing Algorithm for 6LoWPAN INTRODUCTION Wireless sensor network (WSN) is one of the fastest growing areas in networking world today. In order to convert WSN from personal area network (PAN) into low power personal area network (LoWPAN), IEEE standard 802.15.4 was introduced. However, future WSNs would consist of thousands of nodes and these networks may be connected to others via the internet. Hence, IPv6 over LoWPAN (6LoWPAN) is defined by Internet Engineering

A typical data center harbors many thousands of hosts. The architectures of data center networks are of two types. Data center network designs are Server-routed networking design Switch-routed networking design Server-Routed Networking Design: The server-routed networking design of a DCN consists of Core (layer 3) switches, TOR (top of the rack or layer 2) switches and server racks. It basically has two tier switching involved for routing a packet. It has a recursively defined structure. In general

has seen huge advancement in the devices that we use for the access of the networks, applications and services that we have become so dependent on. But the underlying network has not seen any change in the same time frame. SDN & NFV represent the

understand the performance of the proposed approach to detect DDoS attack. The real experiments conducted on the testbed to evaluate the performance of the IDR system shows that it is a very effective solution in protecting the network against DDoS attacks. Other network based DDOS defense mechanism is the effectiveness of the probabilistic packet marking for IP traceback [5]. The simplest way of identifying the physical source of DOS attack is eliminating the IP address spoofing but this approach
