Software Defined Networking A Literature Review

SOFTWARE DEFINED NETWORKING A Literature Review Presented to Prof. Sharmin Khan Department of Computer Science San Jose State University In Partial Fulfillment Of the Requirements for the class CS200W By Hina Mohare April 2016 ABSTRACT Software Defined Networking (SDN) is a rapidly growing technology which has received lot of attention. It addresses some of the long-standing challenges in the field of computer networks. It simplifies and makes it easier to management network. The core idea behind SDN is to pull out the intelligence from network devices like switch and router so that entire network can be controlled from a centralized single controller. The SDN controller has the global view of entire network devices. The controller can be customized by the network administrators or by the engineers as per the need of the business. The SDN technology makes the network programmable, agile, dynamic, scalable, flexible and centrally controlled. This paper initially focuses on the need of SDN. In the later part consists of architecture of the SDN enabled network, its different applications, challenges in implementing SDN. Table of Contents 1. Introduction 1 2. Need of SDN 4 3.

3D Printing Free Essay Example, 1250 words

ZPrinter 350 developed the latest 3D printing technology in 2009 that defined improved accessibility, speed, usability, efficiency, and affordability (Bogue, 2013). Materials and Processes 3D printing technology uses different types of materials depending on the required product. Some of the materials used in 3D printing include alloys, polymers, glass, metal, and plastic. Notably, 3D printing involves arranging the materials in different layers and designing different shapes to complete the additive process (Lipson & Kurman, 2013). In 3D printing, manufacturers use standard inkjet printing technology to develop layered parts by depositing a liquid binder onto thin layers of powder (Z Corporation, 2005). Consequently, the print heads moves over powder and prints cross-sectional data sent from. stl, .wrl, .ply, and. sfx files through a feed piston and platform (Z Corporation, 2005). Indeed, 3D CAD software export 3D models as standard and printable file formats for 3D printing (Z Corporation, 2009). Evidently, the 3D printing process aims at transforming a digital model or design into a physical product of any geometrical dimensions. Using the standard and printable fi le formats for 3D printing, manufacturers launch ZPrintâ„ ¢ software in a PC that slices the 3D model file into various digital cross-sections, or layers (Z Corporation, 2009). We will write a custom essay sample on 3D Printing or any topic specifically for you Only $17.96 $11.86/pageorder now Consequently, the ZPrinter prints every layer and places the layers on one another to develop a unique product. A short drying cycle culminates the 3D printing process by drying the multi-layered products (Z Corporation, 2009). The joining of cross-sectional layers develops the final shape of the physical product (Lipson & Kurman, 2013). Ideally, the 3D printing technology enhances visualization, automation, and cost-effectiveness of 3D data or digital models. The process enhances the production of highly customized products and designs since manufacturers will only feed the ZPrintâ„ ¢ software with relevant 3D data (DAveni 2013). As such, the manufacturer controls the 3D printing process and can initiate changes and incorporate creativity where necessary. Clearly, 3D printing defines an effective, flexible, and modern manufacturing process that applies in various industries. Examples of 3D Printing Applications Printed Car (Strati) The Strati depicts 3D printing innovation and the world’s first 3-D printed car (Kurczewski, 2014). Local Motors designs and builds the two-passenger car. The 3D printing innovation uses carbon fiber-reinforced thermoplastic material to manufacture the Strati.

Autumn Journals Mary Yocum How does the use of multiple perspectives change your understanding of the characters and plot in this section? The first part of this section is told by Claudia. In this part she describes her early memories and what it was like to grow up for her. In her description the reader starts to get an idea of how life for the black characters was at that time. Claudia tells about how she encounters the idealized standard of white beauty, both from her perspective as a child and later in life. The reader is able to see Claudia’s confusion with society’s ideals and how she reacted to them as a child, with hate towards the ideal. Then Claudia’s view as an adult who fully understands the ideals gives the reader a wider view of her experiences as a child. By writing this part from Claudia’s perspective, child and adult, the author lets the reader understand how life was for Black Americans in a society that was idealized towards the white middle class. The next part of the section is told from the viewpoint of a narrator. In this section the reader is introduced to the Breedlove family.

A Night to Remember Decadence of The Titanic Essay

The Soap ad in the 1958 film A Night to Remember is one of the first implications of social class that is illustrated throughout the entire film. It begins by first introducing the viewer to the middle class hero, Lightoller and his view of the class system of 1912 where he mocks the discrepancy of class aboard the Titanic amongst the elites and the lower class passengers (Bruce). And despite this, the advertisement seems to better illustrate the idea of decadence that is found on the ship. As already noted, the scene seems to mock the elite class as Lightoller states that the soap is â€Å"for the first-class passengers, mark you. The rest don’t wash† (A Night to Remember). It is here, that class is clearly evident through the reaction of the†¦show more content†¦By advertising these social embellishments, it advertises the high class sophistications of the ship and is therefore attempting to attract the upper class with its promise of arriving to lavish desti nations on one of the most technologically advanced and its luxury living accommodations. The fact that Lightoller pokes fun at this single line demonstrates his social standing as a middle class citizen. The contrast the social classes in this film by this single scene is also evident through the reactions of the characters. As already noted the elite couple is stiff, uptight and are humorless towards Lightoller’s reaction to the Titanic’s embellishments. As opposed to Lightoller and his wife’s reaction whose is mocking and giggling at the elitist notion of luxury. And also makes a note saying â€Å"soap is no laughing matter† (A Night to Remember). As a means to not offend the upper class passengers, Lightoller remarks that he is not necessarily poking fun at the elite social class but he is only mocking â€Å"of the embellishments† (A Night to Remember). Although the viewer is given a clear distinction as it allows us to believe that he is inde ed making fun of the upper class treatment of the lower class. It is clear that even at the beginning of the film, the motif of decadence amongst the elite classes is evident throughout the entire film.

Masculinity vs. Femininity Free Essays

Masculinity vs. Femininity Geert Hofstede Here you can see four persons, three of them are adults and the other one is a student. One of the adult seems to be the principal of a school, the other two seem to be the parents of that student. We will write a custom essay sample on Masculinity vs. Femininity or any similar topic only for you Order Now Those people are in a room, which seems to be the bureau f the principal since the sign on the door says â€Å"principal†. The reason why the parents of the student and the principal meet is because the student is not good in school. The principal is about to tell them their son will fail the third grade. Then the father says that he doesn’t understand why his son is so bad in school, and asks what they, himself and his wife, did wrong. The wife answers then that her husband is the one that owns a gun. Therefore you can say that the reason why the student is so bad is due to â€Å"family problems†: His father having a gun. The way the wife says â€Å"You’re the one that owns the gun† seems as if the father uses his gun as a warning, this could lead to fear of the son and this would affect the son’s results in school. In this picture you can say that the father has the power in the family especially showed by him owning a gun, and the mother and wife is only his subordinate. That is why this picture is an example for the masculinity versus femininity by Hofstede’s model. This dimension indicates the extent to which dominant values in a society tend to be assertive and look more interested in things than in concerning for people and the quality of life. â€Å"Masculinity is the opposite of femininity; together, they form one of the dimensions of national cultures. Masculinity stands for a society in which social gender roles are dearly distinct: men are supposed to be more modest, tender, and concerned with the quality of life. † (Source: Hofstede, page 262) â€Å"Femininity stands for a society where gender roles overlap: both men and women are supposed to be modest, tender and concerned with the quality of life. † (Hofstede, page 261) The Masculinity and Femininity dimension describes how cultures differentiate between gender roles. Masculine cultures tend to be ambitious and need to surpass. Members of these cultures have a tendency to polarize and consider big and fast to be beautiful. In workplaces employees emphasize their work to a great extent and they admire achievers who accomplished their tasks. Feminine cultures consider quality of life and helping others to fulfill theirselves and help others to achieve their goals . Working is basically to earn money which is necessary for living. In business as well as in private life they strive for consensus and develop sympathy for people who are in trouble. How to cite Masculinity vs. Femininity, Papers

Principles Of Microeconomics A Sample of Economics Solution

Questions: 1. For the pizza seller whose marginal, average variable and average total cost curves are shown in the diagram What is the profit-maximising level of output and how much profit will this producer earn if the price of pizza is $1.18 per slice? 2. Think about the demand for the three popular game consoles: XBox, PS3, and Wii. Using supply and demand diagrams to illustrate your answers, what is the effect on the demand for XBox games or the quantity demanded of XBox games (other things remaining the same) as a result of the following: a. The price of an XBox falls? b. The prices of a PS3 and a Wii fall? c. Programmers who write code for XBox games become more costly to hire? 3. Kim can produce 40 pies or 400 cakes an hour. Liam can produce 100 pies or 200 cakes an hour. a. If Kim and Liam spend 30 minutes of each hour producing pies and 30 minutes producing cakes, how many pies and cakes does each of them produce? b. Who has a comparative advantage in producing pies, and in producing cakes? c. If Kim and Liam specialise and trade, what is the highest price of a pie at which Kim and Liam would agree to trade pies and cakes? What are the gains from trade? Answers: 1. Here at quantity 435, the price is greater than average total cost, which implies that the firm is making profit. At quantity 260, the price is just equal to average total cost. Hence the profit maximizing output is 435 slices. PROFIT= Total revenue (TR)-Total Cost (TC) We find FC : TC= 260*1.18=306.8, AVC= 0.69*260=176.8 ... FC= 306.8-176.8= $130 TR FOR 260 SLICES= 1.18*260= 306.8 Profit= 306.8-30.8= 0 Now for 435 slices: TR= P*Q= 1.18*435= $513.3 TC=FC+VC At output 435 slices, average variable cost (AVC) = $0.77/ slice; VC= AVC*Q= 0.77*435= $334.95 Now, TC for 435 slices= 130+334.95= $464.95 Profit= TR-TC= 513.3-464.95= $48.35 Hence we get higher profit for 435 slices, which makes it the profit maximizing output. The firm earns $48.35 profit. 2. (a) If the price of Xbox falls, then the demand for it rises. The demand curve shifts upward from D0 to D1, with rise in equilibrium quantity Q0 to Q1. (b) As prices of PS3 and Wii falls, the demand for Xbox decreases, and D0 shifts downward to D1. Quantity falls from Q0 to Q1. (c) As the programmers become costly to hire, the cost of producing Xbox games increases, which makes producers decrease supply of Xbox games, hence the supply curve shifts from S0 to S1, so the market equilibrium now shifts to E1 with lower equilibrium output and higher prices. 3. (a) Kim produces 20 pies and 200 cakes whereas Liam produces 50 pies and 100 cakes when given 30mins for each. (b) Liam has comparative advantage in producing pies with a lower opportunity cost of 200/100=2 cakes for baking 1 pie compared to Kims 400/40=10 cakes. Whereas Kim has a comparative advantage in baking cakes with lower opportunity cost of 40/400=1/10 pie per cake compared to Liams 100/200=1/2 pie. (c) In trade Liam sells pies to Kim for cakes at a maximum price of 10 cakes per pie, whereas Kim sells cakes to Liam for pies at a price of 0.5 pies per cake. Each trading at their opportunity costs.As the trade takes place, total production of pies and cakes increase which is the gains from trade.
