Kudler Fine Foods Network Overview University of Phoenix Introduction The Kudler Fine Foods is one the best fine food stores around They have come a long way in such a short period of time However Kudler has out grown the old network infrastructure and is in dire need of an enterprise wide upgrade The strategic goals of the enterprise network are to introduce new technologies in data collection company communication and information protection while providing the best data speeds and network access This is very important because if this is done correctly this will increase revenue and reduce the costs of operation in all the Kudler Fine Foods stores The new network will bring Kudler Fine Foods back up to technological speed while as the same time improving the way they keep track of inventory and sales by using data mining techniques which will be collected and analyzed in real time Network Overview After reviewing of the network at Kudler Fine Foods the network topology that is being used is the bus network The bus network is setup in such a way that all the network nodes are connected via CATS to the bus or communication line All of the sites in the corporation are using the same configuration of workstations servers and standalone ups All of the networks have one way of communicating to the internet and that is by 56k modem The bus network is very cost effective to setup but it can very difficult to trouble shoot because if the backbone goes down the entire network will have an outage The other aspect of this network that is a pain is that fact that if two systems are sending a signal at the exact same time to one another the network will have signal collision meaning that both signals will drop In order to prevent this from happening CSMACD or carrier sense multiple access with collision detection will be setup This in effect will put the network into a listen mode to prevent the collisions from taking place Network Response time One of the major goals is to improve the lack of response time and latency which is currently being experienced on the network due to the 56k modem s installed at all the sites This is a very critical issue because it is very slow and if one modem s goes down there is no other means of communication to the intemet or other sites The first problem of response times latency and jitter that are being seen on the entire network are all related and are being caused by not only the slow network speeds but the out of date systems being used The response time is measured by the time that it takes for a system to respond to user input command This is happening because all the host systems at all sites are running Window 98 and a Pentium II processor which is over 10 years old The latency and jitter issues that are being seen over the network are directly related to the bandwidth available and Jitter is the amount of variation in latencyresponse time in milliseconds What is jitter 2006 This is being caused by the low bandwidth provided by the 56k modem which can only receive up to 56000 bps slow speed means slow response time This is also being caused by the fact that all of the servers on the Kudler network are running Windows NT with Pentium III processors Once these have been replace with new systems and a Tlline which can receive up to 1544 Mbps 27 times faster than the old modem the response time latency and jitter will be significantly reduced This means that the network performance will be able to keep up with all the real time feeds coming from all the Kulder Fine Foods locations for better sales and inventory tracking This will be a great improvement from the existing network and it will ensure that the network has little to no outages and will provide availability 97 of the time Traf c Analysis This of course can only be achieved by conducting traffic analysis on the network Traffic analysis is good for a multiple of reasons from detecting network intrusion to discover response time and latency issue taking place We are concerned about the security of the network and will brie y go over security protocols but this will be covered more in detail in the following papers The traffic analysis that we are concerned about now is that ability to detect when and where a latency issue is taking place There is a multitude of command line tools that one can used but there is one tool that stands out and can provide this vital information This tool is called Wire Shark which allows for a deep packet level analysis of the network so that these problems can be mitigated as soon as they are discovered Some other tools such as Ping provide the user the ability to check network conductivity with a specific node or internet site Trace Route is another command line utility that will show the full connection path between the users system and the determined destination system that is trying to be reached This is very important because this can decrease the outage times on a switch and routed network by identifying which devices is not passing on the packets and where the packets drops are taking place This brings up another important issue and that is the ability monitor network systems Traffic analysis is important but the fact is that system outages are just one of the many things that occurs Having the ability to detect an outage before it becomes an issue would be the best overall scenario for any network This is why Nagios will be implemented within the Kudler network Nagios Is a powerful IT management system that enables organizations to identify and resolve IT infrastructure problems before they affect critical business processes Nagios 2012 and will be crucial to the new network Nagios provides an alerting system whenever a network device is detect so that it can be fixed immediately Without traffic analysis the ability to discover what systems or network devices are causing problems on the network would be possible but would take a large amount of man hours to pin point were the problem system is on the network Networking Standards One important factor to any network is following the standards that have been set What I meant by this is the ability to connect and share information Open standards allow for this to happen because it allows everyone using different technology such as NIC cards to connect to the internet via CATS If Kudler decided to use a new technology they would be unable to do this because all the networks out there are using the open standard There is no reason to reinvent the wheel so following the standards that have been set is vital to any network The following list of a few originations that provide networking standards which will be followed on the new enterprise network for Kudler Fine Foods 0 Institute of Electrical and Electronics Engineers IEEE 0 Wireless Ethernet Compatibility Alliance WECA 0 Internet Engineering Task Force IETF The Institute of Electrical and Electronics Engineers is the organization that set the standards for all networks across the board This means that wireless networks also fall into this category The IEEE has a massive amount of information and standards that will become valuable information for this new network This is not the only organization this is important when it comes to standards because WECA is one that is vital as well Since there is a WLAN incorporated into this network it is important to understand what WECA does The Wireless Ethernet Compatibility Alliance was setup to ensure the crossvendor compatibility of 80211b wireless networking hardware and software Kozierok 2005 This is vital because if everyone had their own was to communicate in terms of wireless devices then nothing would work Last but not least is the Internet Engineering Task Force which plays a very important role when it comes to releasing the standards in networking The way we communicate via TCPIP is standard that was set by this group Though there are many more groups that provide standards out there it is always important to remember that they all have to work together as well This is why incorporating these standard are imperative to follow Protocol a nd Security overview One of the most important factors to any company is the security of their network Even if Kudler Fine Foods spent a million dollars on the new enterprise network it would be render useless if it did not provide the protection to the information it was designed to collect This is why it is very important to choose the correct communication protocols which should be based on the equipment being used with the network infrastructure and making sure that within the communication protocols that the correct individual protocols are chosen to provide the security that is needed For instance TCPIP is a communication protocol but within the TCPIP stack are protocols that allow for communication to take place such as port 80 or HTTP Depending on the technology on the network these communication protocols will differ The TCPIP operates at layer 3 and 4 of the OSI model The OSI model is the standard for the way communication takes place Since the new enterprise network will be incorporating a wide area network to connect all the sites which will have their own individual wireless local networks Choosing the correct communication protocol stack is vital to the security and availability of both the WAN and WLAN network The fact that the wireless local area network will be providing vital data the WPA2Enterprise option has been selected for authentication and is one of the most recommended ways to secure a WLAN WPA Enterprise utilizes 8021 X authentications by means of a RADIUS server The RADIUS server Is a clientserver protocol and software that enables remote access servers to communicate with a central server to authenticate dialin users and authorize their access to the requested system or service Thomas amp Oosten 2006 This will provide user account certificate based authentication to take place and will for signal based authentication sign on to the wireless network The one vital protocol that is very useful with this implementation is port 443 or HTTPS This protocol uses SSL over HTTP which will encrypted any communication going over this port This is very important to prevent network sniffing from unwanted personal and will provide DLP or Data Loss Prevention Once WPA2 Enterprise is in place it will provide not only the secure access that is needed but the security protection as well when it comes to access control for Kudler Fine Foods One other major piece to be implemented is that each site will have the ability to connect to one another via VPN This will allow a secure communication tunnel to all of the sites The VPN connection will have the ability to be accessed through an additional high speed internet being implemented The VPN will become vital to the operation because it will allow systems to backup on a central server and provide redundancy if the other internet connection goes down With all of the new technology that is planned to be replaced other aspect of the network that needs to be taken into consideration is the phone line There are a couple of choices that can be used from VoIP or Centrix VoIP or Voice Over Internet Protocol uses RTPUDP and IP tofrom a Skinny Client for audio RADCOM Academy 2012 The skinny protocol is used by cisco devices VoIP systems can cost a little more just due to the fact that the systems are owned once they are purchased This is extra overhead that is not needed for Kudler and because of this the CentriX system is the best option CentriX is better due to the fact that the company would not be taking on the cost of the system but only the cost of the service which means when the equipment breaks the service provider is responsible and not the company This provides less overhead and saves money in the long run In conclusion Kudler Fine Foods is one the best fine food stores around They have come a long way in such a short period of time but Kudler has out grown the old network infrastructure The new enterprise network will bring Kudler to a whole new standard with the quality of service and the way that every site is able to collect data communicate and protect information collected The new enterprise network will increase revenue and reduce the operational costs at all the Kudler Fine Foods stores This will then in turn allow Kudler to lower their prices while still providing them the ability to offer only the best food products in the state of California References RADCOM Academy 2012 Voice over ip reference page Retrieved 15 January 2012 from httpWWWprotocolscompbookVoIPhtm What
