Introduction The current information technology (IT) infrastructure consists of a mix of 2008 and 2008 R2 servers, with two legacy Windows 2000 servers, and four Windows Server 2012. In addition to the Windows server environment, the network consists of routers, switches, and security appliances, such as firewalls. The environment also consists of important services to ensure the security, and stability of the network. The identity infrastructure is contained within Active Directory, which…
While ubiquitous Internet access is extremely convenient and enables marvelous new applications for mobile users, it also creates a major security vulnerability—by placing a passive receiver in the vicinity of the wireless transmitter, that receiver can obtain a copy of every packet that is transmitted! These packets can contain all kinds of sensitive information, including passwords, social security numbers, trade secrets, and private personal messages. A passive receiver that records a copy of…
Design Analysis A connection is recognized in the optical layer regulates to carry the information among the clients in the network. The optical connection is preserved between a source node, s and destination node, d is known as an light path. The problem in finding a route for a light path with wavelength assigned to the light path is submitted as the routing and wavelength assignment problem (RWA). The problem of RWA is divided into two parts : Routing and Wavelength Assignment. In the…
OMIS 660 Business Computing Environment and Network Lab - 1 REPORT TCP: Transmission Control Protocol SUMMARY: The idea of TCP congestion control is for each sender to determine the available capacity in the network so that it 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…
UML 91.561 Computer & Network Security I HomeWork 1 Name – Nrupen Abnave Student ID -01382247 1.1 (a) Describe the major structure of a TCP packet and explain the main functions of the TCP headers. - TCP is a transport layer protocol and is connection oriented. Its reliable connection, has error checking and flow control. TCP Headers: 32bits Source and Destination Ports – Each 16bit number. Indicate which application is using the communicating stream. Used by most common…
There are many technical requirements. One requirement is to have a internet connection. The environmental requirements are power source, operating latitude and an operating system platform. Table 4: Technical Requirements of HWD (Weng M. , 2016) Environment Temperature: -4° to 113°F Operating altitude: less than 30,000 feet Compatibility Iso Android Windows Sync Method Bluetooth 4.0 or 4.1 Bluetooth Low Energy 2.7 Leading Healthcare Wearable Device Brands Wearable continues to develop…
3. Results and discussion 3.1. Grafting of CNT on the ramie fabric The schematic representation for the mechanism of ramie fiber surface treatments is shown in Fig. 2. For the alkali treatment of ramie fiber, the NaOH reacts with the hydroxyl groups of the ramie fiber as shown in Fig. 2(a). During silane treatment, the hydrolysis of silane takes place initially (Fig. 2(b)) which then reacts with the active hydroxyl functionalities in ramie fiber (Fig. 2(c)). Each silane molecule has three…
can be processed. The congested routers can discard queued packets to make room for those that are arriving. 4. This layer divide the data into segments and also ensures that data must be received in the same sequence in which it was sent. The protocols that are used are TCP and UDP. The data link layer is responsible for encapsulation of packets into frames and then transferring them to the physical layer. It is also responsible for flow control and addressing. 5. A three-way handshake is…
support and enable. The northbound API is not standardized and often allows fine-grained control of switches. Applications should and do not need to process details of the southbound interface, such as details about the network topology [14]. OpenFlow protocol provides an interface that allows a control software to program switches in the network. Basically, the controller can change the forwarding behaviour of a switch by altering the forwarding table. This is where network programming…
