Network Management

NTC/411

Introduction
Today with technology evolving so does the system(s) that it affects. In the varied performances of each requirement there are also a set of protocols that are adhered to when information is transmitted across the network. In this paper a few of those protocols will be introduced along with how management of network traffic is performed through the use of out-of-band (OBM) and in-band methods. Managing a network involves various tools and knowledge of the organizations system in order to remain on top of the issues or problems that continue to plague the network which includes but not limited to hardware break downs, intrusions, disasters and security. Also addressed in this paper are the effects of enterprise systems and its influence by business intelligence (BI) as well as decision support systems. Out-of-band/In-band Network Management

Managing of networks may occur when network managers need to respond remotely or within the sites network. Two of the methods described here are the out-of-band and in-band network management. In-band management as defined by Tulman “An in-band management involves managing devices through the common protocols such as telnet or SSH, using the network itself as a media.” (Tulman, 2010) While the in-band management is most common and widely used it does have its drawbacks such as only being operational during full operation of the system. In-band basically is a way to manage locally through the site’s network utilizing telnet connectivity to a router. If the network is down there is no way for in-band to access the necessary components affected and for the manager to resolve the problem. A secure, remote emergency access to the network to manage as well as to troubleshoot is needed if the component is not available on the network. A method included in in-band management is Simple Network Management Protocol (SNMP) using HP’s OpenView suite as an example to handle such activities. Also for in-band its methods alone are insufficient in large or any mission critical networks. For this an alternate method of access is recommended and that source is the out-of-band management. Out-of-band management involves utilizing a dedicated channel of management to maintain its devices on a network. In its description provided by Microsoft System Center as “Out of band management allows an administrator to connect to a computer’s management controller when the computer is turned off, in sleep or hibernate modes, or otherwise unresponsive through the operating system.” (Overview of Out of Band Management, 2009) Out-of-band management is utilized when the first source, in-band management, is unavailable to access the network nodes that are experiencing the problems. OBM services for emergencies may include remote management consoles and Windows server software therefore one can manage the network if part of the system is down or turned off. When utilized with data network OBM is in place as a separate network (parallel) used to control and manage the network. An advantage for out-of-band is the network traffic is not impacted because it only runs when the primary source (in-band) of resolution is unavailable not when the network is up and running. Out-of-band management provides coverage to many devices that may not be directly connected to the network such as the Private Branch Exchange (PBX) system and uninterruptible power supplies (UPS). Both in-band and out-of-band network management supplement one another as both are utilized to resolve network issues in a timely manner. Influences of Enterprise Systems

Business strategy is vital to any organization for it develops competitive advantages for the company. Enterprise systems “overall combination of computer hardware and software that a business uses to organize and run its operations.” (Enterprise System, n.d.) The enterprise systems are utilized for...
