The term in-band and out-of-band would refer to whether if the solution would sit in the flow of data or out of the flow and analyzing some of the flow of live data. The first part of this paper will be from researching the internet about the topic and what I find. The second part of the paper will discuss the advantages, disadvantages, and differences of both.I will start off with what I have found from researching the topic. The one research page I found was from
The disadvantage of the out-of-band network management is that it is costly compared to in-band management. The one thing to consider is that each method has pros and cons, but obtaining a budget for the additional equipment for out-of-band management will be a struggle. You have to justify and show the need for the additional equipment by showing how it will save the company money and labor all the while keeping the network running at peak.Now let’s take a look and talk about each of the management types and the protocols used with each. From some of the research I have done is that the protocols used for each can range from SNMP (Simple Network Management Protocol). And with that there has been 3 versions released since its release.  MIB is a collection of managed objects, which stores information about them that can later be retrieved by the SNMP. Telnet is also one of the protocols that can be used for in-band network management but not for the out-of-band because it need an internet connection in order to use it from outside the office. This is due to it using the TCP/IP protocol which is good for the in-band management and is used in the command line window. This is an example of a telnet session command: telnet 192.168.0.22 80, the numbers are the IP address and the port for the access to the server.In-band network monitoring versus out-of-band network monitoring will have different effects to the performance of the network. Out-of-band will be in the a device or a way of connecting to the servers or the network without affecting the performance of the network and give the network administrator a way to connect and fix any connection problems if the network goes down. The traffic flow for this would be centralized at the access point and would have no effect to the regular flow of data on the network. In-band would be set somewhere in the flow of data and allow the administrator a way to see what is affecting the bandwidth and possibly any attacks on the network. If attacks were present they could be isolated and stopped with the in-band solution and this would have to use bandwidth of the network to stop the attack. The performance of the network using an in-band solution would degrade some of the performance of the network because of the constant monitoring, but can be setup to just gather data and not utilize to much bandwidth of the network. The use of in-band and out-of-band solutions for a network have many differences, it would be a good practice to have both implemented on a network so that if any problems should arise, the administrator would have access to fix the problem.Here are some examples of different devices used for both in-band and out-of-band network monitoring.
