...EXECUTIVE SUMMARY MPLS, or Multiprotocol Label Switching, is a next generation, more intelligent nnetwork that will enable companies to expand their current infrastructures to do a wide variety of services. Since MPLS is independent of access technologies, it will allow subscribers to access differing access links without changing their current environment. MPLS takes the control of IP routing and combines it with layer 2 switching to give a seamless solution to the many needs of companies today (Semeria, 1999). The goal of MPLS was to standardize protocols that used label-swapping forwarding techniques to support unicast and multicast routing (Yuan, 2002). Many ISP networks today are built using an overlay model, in which IP’s topologies run independent of layer 2 switch topology, such as ATM and Frame Relay (Semeria, 1999). MPLS took advantage of the rapid advances in semiconductor components and focused on separating the routing and forwarding problems from each other; layer 2 switches provide high-speed connectivity, while IP routers, interconnected by a mesh of layer 2 circuits, provide intelligence to forward IP datagrams (Semeria, 1999). With these two topologies combined, you are able to get a fast, intelligent network. MPLS is used by many network operators today because it can support a diverse legacy system as well as modernize them for next-generation applications (Cisco, 2013). Because of its many uses, MPLS can be used to facilitate many different forms of...

...A report on MPLS-VPN VIT Submitted By Sameer Narula FMG19C 191169 Multiprotocol Label Switching (MPLS) is a mechanism in high-performance telecommunications networks which directs and carries data from one network node to the next. MPLS makes it easy to create "virtual links" between distant nodes. It can encapsulate packets of various network protocols. MPLS is a highly scalable, protocol agnostic, data-carrying mechanism. In an MPLS network, data packets are assigned labels. Packet-forwarding decisions are made solely on the contents of this label, without the need to examine the packet itself. This allows one to create end-to-end circuits across any type of transport medium, using any protocol. The primary benefit is to eliminate dependence on a particular Data Link Layer technology, such as ATM, frame relay, SONET or Ethernet, and eliminate the need for multiple Layer 2 networks to satisfy different types of traffic. MPLS belongs to the family of packet-switched networks. Customer site Large customer site Customer Network (C-Network): the part of the network still under customer control Provider Network (P-Network): the Service Provider infrastructure used to provide VPN services Customer Site: a contiguous part of customer network (can encompass many physical locations) MPLS operates at an OSI Model layer that is generally considered to lie between traditional definitions of Layer 2 (Data Link Layer) and Layer 3 (Network Layer), and thus is often...

...You are experienced in information management and its benefits and challenges. You manage online accounts across multiple mobile devices and computers—and social media, texts, photos, videos, music, docs, address books, events, downloads, and other content that make up your digital library. Not being able to transfer and synchronize whenever you add a device or app is annoying and inefficient. To simplify add-ons, upgrades, sharing, and access, you might leverage cloud services such as iTunes, Instagram, Diigo, and Box.net. At some point, a user may want to start over with the latest mobile device—and re-organize everything to make dealing with information and devices easier. That's a glimpse at the information management situations facing organizations today—and why a plan is needed to guide, control, and govern IT growth. As with building construction (e.g., Figure 2.1), blueprints and models help guide and govern IT assets. Image from book Figure 2.1: Blueprints and models, like those used for building construction, are needed to guide and govern an enterprise's IT assets. To better reflect organizational content, the term information management is used instead of data management. The most potentially valuable and challenging type is human information—the semistructured or unstructured content generated by humans from social media, mobile devices, search engines, and sensors as well as texts, images, audio, and video. To function in the big, cloudy, mobile and social world...

...Gevork Darakhchyan NT 2640 Unit 10 assignment1 Frame relay migration to MPLS Frame relay | MPLS | Frame Relay is based on the PVC or Permanent Virtual Circuit. You access the network using a specialized piece of customer premises equipment called a FRAD or Frame Relay Access Device. Within the network frame routers are configured by the network operator to create your PVCs from a list of sources and destinations and your desired bandwidth or Committed Information Rate (CIR). | MPLS or Multi Protocol Label Switching is also a private network arrangement. It's designed to run on the newer IP based networks that are replacing traditional circuit switched or TDM (Time Division Multiplexing) networks. The multi-protocol aspect allows all sorts of traffic to be carried on the network simultaneously. What MPLS layers over the core IP network is a specialized label system. Each label specifies source and destination and quality of service. The labels work something like the virtual circuits of Frame Relay in that they identify where packets are coming from and where they are intended to go. | Benefits * Keeping cost of ownership and technology complexity low at point-of-sale and branch endpoints, ensuring fast service activation. * Deploy products to enable simultaneous delivery of private line, Frame Relay, and MPLS services during the transition phase to avoid service interruption. * Build MPLS-compatible traffic quality classification, performance, and quality standards...

...Frame Relay Migration to MPLS Frame Relay is a standardized wide area network technology that specifies the physical and logical link layers of digital telecommunications channels using a packet switching methodology. Multiprotocol Label Switching (MPLS) is a mechanism in high-performance telecommunications networks that directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table. Frame Relay aimed to make more efficient use of existing physical resources as clients were unlikely to be utilizing a data service 100 percent of the time. In more recent years, Frame Relay has acquired a bad reputation in some markets because of excessive bandwidth overbooking by these telcos. Telcos often sell Frame Relay to businesses looking for a cheaper alternative to dedicated lines; its use in different geographic areas depended greatly on governmental and telecommunication companies' policies. Many customers are likely to migrate from Frame Relay to MPLS over IP or Ethernet within the next two years, which in many cases will reduce costs and improve manageability and performance of their wide area networks. Multiprotocol Label Switching (MPLS) enables Enterprises and Service Providers to build next-generation intelligent networks that deliver a wide variety of advanced, value-added services over a single infrastructure. This economical solution can be integrated seamlessly over any existing infrastructure...

...fiduciary duty to either, or both of SB and MPL, ultimately depends on the nature of its relationship at any given time with the parties in question. For this I consider the situation with each of the counterparties to OB individually, and throughout the various stages of the financing deal. Relationship with MPL A fiduciary relationship is one of confidence and trust whereby one party assumes particular obligations to act in good faith and not against the interest of another (i.e. counterparty). Fiduciary duty arises automatically when the relationship is one of agent and principal; trustee and beneficiary; director and company; partner and partner; or employer and employee. In its dealings with MPL, OB appears to be primarily engaged in a banker and customer relationship. As this does not fall under any of the categories of relationships specified above, there is no inherent fiduciary relationship. That being said, OB may have assumed a fiduciary capacity under common law, subject to satisfying the conditions arising from the Hospital Products Ltd vs United States Surgical Corporation (1984) 156 CLR 41 case. OB would be a fiduciary to MPL if it can be shown that it was acting in its interest and in a dominant position rendering MPL vulnerable to potential abuse. On the given facts, there is no clear-cut case to suggest that MPL, by virtue of its directors’ expertise, is vulnerable to abuse by the dominant OB. Therefore OB does not owe MPL a fiduciary duty on the basis of this...

... b. Find an expression for the marginal product of labor, MPL, when the amount of capital is fixed at 81 units. Instruction: The second response is the exponent on L in the expression. Round your responses to 2 decimal places. MPL = *L ^ Then, illustrate that the marginal product of labor depends on the amount of labor hired by calculating the marginal product of labor for 16 and 81 units of labor. Instruction: Round your responses to 3 decimal places. MPL when L = 16: MPL when L = 81: c. Suppose capital is fixed at 81 units. If the firm can sell its output at a price of $200 per unit and can hire labor at $50 per unit, how many units of labor should the firm hire in order to maximize profits? Instruction: Enter your response as a whole number. Explanation: a. When K = 81 and L = 16, Q = (81)0.75(16)0.25 = 54. Thus, APL = Q/L = 54/16 = 3.375. When K = 81 and L = 256, Q = (81)0.75(256)0.25 = (27)(4) = 108. Thus, APL = 108/256 = 0.422. b. The marginal product of labor is MPL = (1/4)*(81)0.75(L)-3/4 = 6.75*(L)-0.75. When L = 16, MPL = 6.75*(16)-0.75 = 0.844. When L = 81, MPL = 6.75*(81)-0.75 = 0.25. Thus, as the number of units of labor hired increases, the marginal product of labor decreases MPL(16) = 0.844 > 0.250 = MPL(81), holding the level of capital fixed. c. We must equate the value marginal product of labor to the wage and solve for L. Here, VMPL = (P)(MPL) = ($200)(6.75)(L)-0.75=1350(L)-0.75....

...function. Workers (days) Total Output 1 9 2 17 3 24 4 30 5 35 6 39 7 42 1. Explain, in your own words, the meaning of MRP. Starts with Marginal Product Labor (MPL) the amount of additional worker adds to your total output. Usually the MPL falls when you add an additional worker. So when working with Marginal Product Labor, it depends on the cost of wages and how much you are willing to spend on wages. The higher the wages the there are fewer workers. The lower the wages, you will have more workers and this leads to more output but can also be less productive workers. 2. How is MRP computed? You take MPL and multiply with the going price of the unit. 3. Using the data presented, in the short run, how many workers would you recommend Sullivan's hire per day to maximize profits? I would recommend four workers. 4. Explain how you arrived at this number. I made a chart and first figured out the MPL and with the MPL I multiplied the unit price to find the answer for the MPR. If the going rate of labor is $30 a day, you will want to use the workers as the long as the MRP is greater than or equal to the wage you will pay the employee. We can use four workers and still get $30 in return. You will not see any profit with $25 in return using 5 workers if you pay the worker $30. # of workers Output MPL MPR 1 9 9 45 2 17 8 40 3 24 7 35 4 30 6 30 5 25 5 25 6 39 5 20 7 42 3...

...Introduction (P1) STO State Trading Organization (STO) was established in early 1960’s. When they first start the organization the only resource available was tuna. At that time the development of the country was slow so there is no banking system, no available funds for major investments and no commercial industries as well. After some days in 1994 a fully-funded business was set-up by the government which is named “Athireemaafannu Trading Agency (ATA)”. Their main aim was to provide essential food items to the nation. 9th June 1979 is the day which ATA became STO with so much improvements. After that they kept growing and growing. Now the organization is a highly appreciated company which almost sells all the items. STO can be considered as the best organization in the retail industry in Maldives. STO is a very huge organizations which all the board of directors are set by the government. This is a partnership business. They have 6 subsidiaries in Maldives. At first this organization was a fully government organization but now this organization is partly government and partly managed by an individual. Their main purpose is to enriching lives through expansion and accessibility. Which means letting people purchase their goods freely and openly. They have a very huge shop in male’. And the customer service of the organization is very good. Which is why most of the people select STO as their best place to buy their goods.
