INTRODUCTIONNetwork operating system can be defined as a computer operating system that isdesigned to support different workstations of computer. It mainly includes remote access,connectivity of network devices as well as storage of data with fell network security. There aredifferent NOS used by organizations such as Artisoft's LANtastic, Banyan VINES, Novell'sNetWare, and Microsoft's LAN Manager etc. The present report is based on the Medium sizedcompany named as Cognizant. Company wants to establish a network system in Manchester,UK and also wants to span their network on two floors. Moreover, the overall planning anddesigning of the network connection is described in this report with the overall hardware andsoftware requirements. For this purpose, remote desktop support is essential and it is quiteessential for network manager to allocate the minimal amount of support. In addition to this,Cognizant can expand their business operations by setting their performance baseline as well assecurity and scaling aspects. Disaster recovery methods and security concerns are described inthe present report as per the selected network operating system.TASK 1 NETWORK OPERATING SYSTEM PRINCIPLES1.1 Selection of NOSAs a network manager it is quite essential for me to develop a best network operatingsystem for Cognizant through which company can expand their business operations effectively.There are different types of operating system some of which are open source or free of charge. Itis the best way to provide a platform to company to operate different application software. Withthe help of the Network operating system company can easily manage all their network resources(Cheng and et.al, 2011). There are different types of NOS such as:Artisoft's LANtastic:This type of NOS Mainly supports a wide variety of computeroperating system. These are the different computer operating system such as WindowsXP, Windows NT etc. It is a user friendly NOS and people can easily go through itsinstallation process. It also provides a chatting feature that allows all network PCs tocommunicate with each other. In addition to this, it is very easy and simple to maintainand it does not requires any extra cost for maintenance.4
Novell's NetWare:This network operating system is totally based on the XNS protocolarchitecture (Hart, 2013). There are various desktops available in the market and itprovide comprehensive support to all the system such as DOS, Windows, Macintosh,UNIX etc. One of the main feature is that it supports the open source and licensed bothoperating system.Open Network operating system:It is an SDN network operating system for all theservice providers. It was open sourced on December 5, 2014. It is basically architectedfor performance, high availability, scale out and well defined abstractions and interfaced.In addition to this, it can be stated that ONOS operating system comprises ON.Lab.Microsoft LAN manager:LAN manager is a NOS that is designed and supported by theMicrosoft and runs under the Microsoft OS. This system also supports a goodmultitasking functions as well as other OS such as DOS, Windows etc.As per the given scenario, Cognizant uses ONOS (Open network operating system) isbeing used as it is a open sources and it is based on the software define network. It bring out theinnovation and openness to the internet and cloud infrastructure with the help of the open sourcetools and platforms. It helps the company in establishing local area network and sharing all theinformation remotely. It also helps in distributing control platform for large scale networks andfocus on the reliability and scalability.1.2 Disaster recovery availability and security in context of NOSNowadays in any organization one of the major concern is to go through the best networkavailability. Disaster recovery can be define as a area through which company can go through thesecurity planning of all of the negative events. All such negative events includes anything thatputs an organization's operations at risk such as hacking, cyber attacks etc. At the time of usingany NOS the major problem is faced by the IT director is some sudden damages such asphysical damages to equipment like computer, routers as well as information loss. While usingONOS company can get secure and effective disc backups (Karsai and et.al, 2011). In order toovercome with the problems of sudden damages IT manager need to adopt best backup plans sothat they can keep their data secure. Managing and controlling the internal and external interruptsin the network system is define as a process of disaster recovery. Moreover, it can be stated that5
security is the major concern that company should follow and for this purpose they need to adoptvarious security controls in order to prevent unauthorized access. For this purpose, Cognizant hasdeveloped a disaster recovery and business continuity plan.1.3There are different types of NOS available in the market. As per the given requirementsand considerations Cognizant has adopted ONOS. The operational need of company can befulfill by adopting this system. They can easily go through the proper network implementationplan through which they can set up 30 and 40 computers on two different floors. This ONOSprovides them high features on low maintenance cost (LAWRENZ, 2013).There are differentservice provider networks are available as WAN core backbone, Metro networks, Cellular accessnetworks, wired access etc.In the present scenario, the disaster recovery practices for currentNOS company can further use disaster recovery module. It can further managed by the databasecloud backups as well as services. It is essential to recognize all the threats and issues thatoccurs. In order to prevent the damages a action plan should be developed. Security is the majorconcern of any company as they need to keep their data secure and protect. With the help offollowing several security issues company can manage all the damages and keep them secure.The ON.Lab is a non profit organization founded by SDN investor which brings innovative ideasfrom leading edge and deliver high quality service open source platforms. Due to the freeavailability it is quite essential to keep full security. For this purpose Denial of services (DOS)will be used when deserializing malformed packets in ONOS. When attackers try to exploit theDOS flaw they only need to be able to send malicious crafted packets through the switchedcontrolled by ONOS. In addition to this, most of the SDN controller includes the host tracking aswell as allow host to migrate between different physical locations in the network.TASK 22.1 Detail plan of implementation of ONOSFor the better implementation of the selected NOS it is quite essential for company tofulfill all the requirements such as hardware, software requirements as well as best backupmethods and security policies that company should use.6
