The campsite reservation system changed from carbon-copy forms to a data based information system. The park firstly applied was Reservation Operating System (ROS). However, problems of park reservation system emerged constantly. Measures had been taken during 2007 to 2010 to improve the system. Nevertheless, some serious issues are still remained, and need to be resolved urgently, and find out a permanent solution to improve the overall operational process. In 2010, Saskatchewan Provincial Park renewed the reservation system, and applied Online Reservation Administration System (ORAS). However, the system crashed on January 1st, the same day it went live. Saskatchewan Provincial Park reservation system is currently facing the following problems: 1) the problem of the reservation software, and the problem of centralized process operation; 2) the problem of intensive-labor, and employees are lacking in trainings; 3) trust and loyalty issues from customers; 4) the bad effect on provincial economy for the failure reservation...

...A. Integrity of Network Security Introduction New security policy created for e-mail will ensure e-mails are used for business purpose and limits personal usage of e-mails. Policy also permits Softsearch to monitor employee’s e-mails if required. Controls implemented by e-mail policy will help prevent confidentiality breach. However, e-mail policy does not govern attachments within e-mails. Policy should be enhanced to include e-mail attachment specific statement to prevent employees from opening attachments from unknown source & forwarding such attachments within the company network. Internet policy prohibits employees from visiting indecent, illegal and pornographic sites, participate in online gaming, streaming videos, download pirated software. These measures will reduce Softsearch network’s exposure to virus and hacking attempts. In addition to these prohibitions for internet usage, policy should be enhanced to include prohibitions for social media websites (Facebook, Twitter etc.), online blog, online document stores (Google Drive, DropBox etc) to ensure no private company information is shared. This may expose that can be sent to external e-mail addresses. This may expose Softsearch with confi confidentially if private information is sent to external e-mail addresses. E-mail policy should be enhanced to include statement regarding no attachment policy for external e-mail addresses. Employee’s can e-will be able to and internet usage addresses softsearch...

...The network that I will explain is my home network, which internet connectivity is provided by Comcast. Wireless connection comes from a wireless connectivity access modem from Comcast which gives access to our devices (computers, television, smartphones and tablets). The information that is communicated through my network is mainly music, videos, web browsing, and video chat. Most of the times the usage is mostly at night time, our network has never gotten a slow connection. Each Comcast wireless modem comes with accessibility password to access the wireless connection; this prevents unauthorized usage of the internet connection. Comcast also provides internet security software through McCaffe which monitors user activity, antivirus, spam and pop up blocker. Also firewall it is provided by the operating system in the computers, and tablets. For smartphones I found that lockout security mobile app is working decently to keep the phones secure and clear from memory clutter. Some other software I have tried has always ended up finishing their trial version or was limited in because they were free. On tablets I have had similar problems but since I have found lockout mobile, I have not had any issues. It is a fact that internet security it is critical in today’s technology world. Hacking has become a business and networks have to adapt and become more complex to be up against hackers. It is important to maintain your passwords and important information secure from any break in...

...Activity 1 New Building New building network setup, tools, medium, etc. List of Tools: * Crimpers * RJ-45 ends/ Connectors * Cable Toner * Toner Probe * Continuity Tester * Fish Tape * Patch Cords List of E equipment: * Cat 5e & 6 * Racks * Conduit Design and Configuration We will begin in the telecommunications room, ensuring we have enough space to set up all our required equipment need for network setup. From there we will map out all other room required to be configured into the network. The cabling of choice is Cat5e. It’s inexpensive, easy to maintain, test, run, and supports the required data transmission rates. Fiber would be great but it is much more costly and susceptible to 90 degree bends. Continuity tester will tell us if the cable to be bun is in good working condition before we actual setup the network. Easier to prevent problems before they have the opportunity to occur. Crimpers are essential to terminate runs at their desired locations with RJ-45 connectors, thru out the building. Whether they be at a work station, hub or server. Configuring connectors vs. wall jacks saves time and cost, and work just as well with the proper crimper. Patch cords will be used to connect ports to servers/ switches in the telecommunications room to ensure connect ability. Cable toners will help us identify cable runs from end to end. This will help us in preventing connectivity issues thru out the system, ensuring all ports...

Method Status Protocol GigabitEthernet0/0 192.168.40.254 YES NVRAM up up Answer: The problem is that either the IP address is wrong or the subnet mask is wrong. That is because the 192.168.40.9 IP address is not in the same subnet as the default gateway IP address (192.168.40.254). Changing the subnet mask to 255.255.255.0 or changing the IP address to 192.168.40.129 – 192.168.40.253 would resolve the problem. The ping command can be used to check for connectivity, and it was. The tracert command could have been used to see where the ping failed. Scenario 2: One user complains of lack of connectivity to certain resources...

...Unit 4 Assignment 1: Create a VPN Connectivity Troubleshooting Checklist 1. Find out who is affected The first step in troubleshooting any VPN problem is to determine who is affected by it. That information can go a long way toward helping you figure out where to start looking for the problem. For example, if everyone in the company is having problems, you might look for a hardware failure on your VPN server, an incorrect firewall rule, or perhaps a configuration problem on your VPN server. On the other hand, if there is only one person who is having a problem who can never seem to remember his/her password or Some other person who insists on connecting from their home computer, that too can tell you a lot about what may be going on 2. Check to see whether users can established VPN connectivity When you begin the actual troubleshooting process, you might want to start by determining whether the affected users can establish VPN connectivity. Not all VPN problems involve connection failures. Sometimes users can connect, but they can't access the network’s resources. 3. Look for policies preventing connectivity If you find that certain users are having trouble establishing connectivity, have them try to log in from a known good machine. If that doesn't work, there may be a policy in place preventing them from logging in. For example, if you are operating in a Windows Server environment, one should check the Active Directory Users and Computers console to verify...

...Network Connections Loribeth Santiago NTC/415 March 2, 2015 Mark Baker Network Connections Providing a sufficient network architecture is an important part of network administration. A good network architecture will provide reliable connectivity for its end users. The most common modes of connectivity are copper, fiber, DSL, coaxial cables, and wireless. Different protocols are used to move data based on the type of connectivity. Each also has a different cost and this plays a big part of the final network design decision. Speed is another factor administrators must look at in order to implement a successful network. Speed will help the company maintain business operations and lends to their overall success. Internet Service Providers (ISPs) use connectivity modes like DSL, Cable TV (CATV), and Fiber to the Home (FTTH) to provide internet access to customers at home. Each option changes as personal and business needs dictate what speed and cost customers require. Network Connectivity Issues Ethernet supports unshielded twisted pair cables, fiber optics and coaxial cable. Ethernet can be subject to physical limitations such as the length of the cable and collisions that can happen on the network. Most twisted pair cabling has a maximum length of 100 meters and supports 1024 users on a single subnet. Carrier Sense Multiple Access/Collision Detection (CSMA/CD) is the access method used in Ethernet. If the network is free and two devices transmit at the same time there...

... Haggard, J. (2014). America’s Embrace of the Mobile Internet : Analyses and Issues. New York: Nova Science Publishers, Inc. In this collection of articles, the editor brings together papers covering three different topics - adoption of mobile internet and how it differs between demographic groups; how culture is able to impact design and usage of mobile devices; and how text and multimedia messaging present new challenges for policymakers. With regard to this proposal, the first article discusses how mobile internet usage in rural areas has lagged behind the rest of the population. The article also points out that while there have been improvements in coverage, the build-out of mobile networks has typically been less extensive than in urban areas. Solution: Mobile/Wireless Internet Its Use: Mobile Internet service could potentially be used in conjunction with site-to-site VPN connections, in order to establish connectivity from the remote locations to the hospital. Application: Mobile Internet hotspot devices could be used to get Internet access in Northeastern Health Services’ remote offices. In conjuction with these hotspots, firewall appliances can be used to establish a site-to-site VPN connection from each of the offices to the hospital’s radiology department. However, because of the lower levels of network build-out in rural areas, there is an increased likelihood of poor network coverage in some or all of these rural locations.

...Network Design Following the acquisition of new premises comprising a two-story office in Adeplhi, Maryland this provides UMUC with the ability to revise and improve their network topology accordingly and ensure that not only is connectivity provided in a consistent fashion but also to provide the required security for information accordingly. One of the fundamental requirements is to ensure that data is segregated in terms of staff and students so this will require the creation of dedicated subnets accordingly to follow through and implement the solution, while there is also a requirement to provide wireless connectivity for students in the lobby area. Given that there is a specific opportunity to develop a comprehensive infrastructure it is important that the fundamental basis in terms of cabling is of a sufficiently high quality to support current and future operational requirements. Due to the size of the building there would be limitations if using Cat 5 based Ethernet cables for example and so therefore there should be a requirement to utilize Cat 6 based Ethernet as this will support a maximum cable length in excess of 300 ft without there being any connectivity or performance issues (Mitchell, 2014). Each of the two floors will have a designated server room that is designed to provide a central point of connectivity for all locations on that floor, and each of the rooms on the first and second floor will require a certain number of data ports based on their expected utilization...

...Network Topologies are in essence the way the network is laid out as it relates to the devices that are connected to it. If you could view all the devices connected to the network, the arrangement would suggest which type the network topology it falls within. The topologies can be described as either a physical or logical design in their defined layout. Network topologies are grouped in the following design categories, Mesh, Bus, Ring and Star Topologies. A mesh topology comes in two varieties, Full mesh and Partial mesh. Full mesh consists of connectivity between every node on the network, meaning each has a direct path to the other. A partial mesh topology consists of the same type of connectivity as a full mesh except you may have to cross nodes to reach another, meaning that direct connectivity may not exist. Mesh topologies rely on routing to be able to choose the correct path between the hosts. One of the largest mesh topologies is the Internet itself. While you may not have a direct connection to a web server, the routers in the path know exactly the best path to get you there. Mesh topologies are considered highly available or redundant. With multiple paths to a destination, one can fail and your connectivity will remain. This leads to mesh networks being very complex. Being complex makes them harder to troubleshoot when issues arise. Along with additional routing overhead and connections, mesh topologies tend to be the most expensive to deploy of the topologies listed...

...Integrative Network Design Project James Warren NTC/362 July 30, 2012 Andrew Carpenter Integrative Network Design Project This paper will discuss Kudler Fine Foods desire to upgrade their current outdated infrastructure with current technology that will let them stay competitive in today’s market. In order to do this they will need to tie all three of their existing sites together using wireless and VOIP technology. Distributed Computing Currently all three of the Kudlers facilities utilizes a distributed computing system using the same configuration of single server and multiple pc’s, each with a single UPS and 56k modem for connectivity. The computers are connected to an Ethernet backbone (typically a hub that is not very efficient in handling network traffic for many computers) and the 56k modem is the only external connectivity that the sites have. Centralized Computing In order to bring this system up to standards they will need to update to a more centralized computing system which all computing is done on a centrally managed computer system and the users use a dumb terminal (thin client) to connect to these central computers. The cost associated with this has been reduced over the years and was only used previously in enterprise environments but now more businesses are moving over to this type of system. Network Topologies Kudlers three offices use almost identical setups for their servers, POS systems and their site connectivity. They all use...

...computers connected to a network of distributed middleware (software connecting client and database: software that manages the connection between a client and a database) . This allows the computers to communicate to each other and also share resources. While allowing the user to use the computer as he or she would use a single integrated computing facility. Examples of failures in a distributed system include, stop failure, Halt failure, Network Failure, and Distributed File System Namespace access failures. Distributed File System Namespace access failures in Windows On Windows Vista and later one of the following error messages may occur: Windows cannot access \\\ The connection may fail due to any of the following reasons: Failure to connect to a domain controller to obtain a DFSN namespace referral, Failure to connect to a DFSN server, Failure of the DFSN server to provide a folder referral. This error typically occurs because the DFSN client cannot complete the connection to a DFSN path. To resolve the issue , evaluate network connectivity, name resolution, and DFSN service configuration (How to troubleshoot Distributed File System Namespace , 2010). Evaluate Connectivity "connectivity" refers to the client's ability to contact a domain controller or a DFSN server.
