...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...

...Solution Scope Our network solution will be MPLS IP VPN; MPLS IP VPN is a fast, packet data transport service that uses high speed switching architecture instead of the typical routers. This type of network will be a change from your traditional network; it will make sure that packet-forwarding decisions are made solely on the contents of this label, without examining the packets. It will also allow all individuals to create end-to-end circuits across any type of transport medium, while using any protocol. MPLS will allow distinct VPNs to use the same address space in turn can also be allocated for private address space. The way this happens is due to its ability in adding a 64-bit route distinguisher (RD) to each IPv4 route, making VPN-unique addresses also unique in the MPLS...

...Structure of WAN After much deliberation it has been decided that all ABC Company’s (ABC) main design centers in: San Francisco, Detroit, Paris, Tokyo and Sao Paulo and sales offices in: Washington, Indianapolis, Tampa and Liverpool, will each have their own Local Area Network (LAN) setup. These LAN’s will be designed to best facilitate their intranet needs and will have the inclusion of internet access. Each site will include switches and routers with other networked devices and will be designed off Star topology. The Star Topology is a common network configuration in which workstations and other network devices connect to a single point called the hub. (Exforsys, 2008) We will be installing Fiber optic cabling in all the main building design centers including San Francisco, Detroit, Paris, Tokyo, and Sao Paulo. The rest of the sales offices be taken into consideration since there are plans of opening other sale offices as the business continues to grow. The fiber optic will run from the backbone cabling, vertical cabling, and horizontal cabling. It will run to the telecommunication closet connecting to the switches. The fiber optic cabling will help provide the necessary speed for all the workstations and expansion for future growth. The connections from device to device will be done through a Layer 3 switches. A layer 3 switch is a high performance device that differs very little from routers. The layer 3 switch has the same IP routing table for lookups and it forms...

...Running head: NETWORK DESIGN FOR ACME Network Design for Acme Manufacturing Learning Team A: [your team members] University of Phoenix Intro To WAN Technologies NTC/242 Acme Manufacturing Network Design Introduction As a network consultant hired by Acme Manufacturing, the company has asked Team A to develop a new networking design for their expanding business. The description below describes the key steps involved in developing a WAN for Acme Manufacturing. The company has six different buildings in six different locations throughout the world which need to be networked collectively. All the remote locations need to be able to communicate effectively with the main headquarters which is located in Atlanta, Georgia. The two buildings which house the headquarters are located across the street from each other. One building is used solely for corporate operations while the other building is used for staffing the sales and engineering department. Network Topology The best choice for the company would be to use a LAN with routers and Ethernet cables. This is a logical choice because the speeds of the network will be far superior and will help to reduce the total cost of the network. The three distribution buildings are located in Chicago, Phoenix, and New York. It is not feasible to run cabling to theses locations due to cost, so using T3 leased lines to communicate is the recommended method to connect the buildings with headquarters...

...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...

...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...
