I thought I deserved better for the time I put into it, but the teacher didn't understand it,. so he gave me a B -CMIP vs. SNMP : Network ManagementImagine yourself as a network administrator, responsible for a 2000 user network.This network reaches from California to New York, and some branches over seas. Inthis situation, anything can, and usually does go wrong, but it would be your job as asystem administrator to resolve the problem with it arises as quickly as possible. Thelast thing you would want is for your boss to call you up, asking why you haven't doneanything to fix the 2 major systems that have been down for several hours. How doyou explain to him that you didn't even know about it? Would you even want to tellhim that? So now, picture yourself in the same situation, only this time, you wereusing a network monitoring program. Sitting in front of a large screen displaying amap of the world, leaning back gently in your chair. A gentle warning tone sounds, andlooking at your display, you see that California is now glowing a soft red in color, inplace of the green glow just moments before. You select the state of California, and itzooms in for a closer look. You see a network diagram overview of all the computersyour company has within California. Two systems are flashing, with an X on top ofthem indicating that they are experiencing problems. Tagging the two systems, youpress enter, and with a flash, the screen displays all the statitics of the two systems,including anything they might have in common causing the problem. Seeing that bothsystems are linked to the same card of a network switch, you pick up the phone andgive that branch office a call, notifying them not only that they have a problem, buthow to fix it as well.Early in the days of computers, a central computer (called a mainframe) wasconnected to a bunch of dumb terminals using a standard copper wire. Not muchthought was put into how this was done because there was only one way to do it: theywere either connected, or they weren't. Figure 1 shows a diagram of these earlysystems. If something went wrong with this type of system, it was fairly easy totroubleshoot, the blame almost always fell on the mainframe system.Shortly after the introduction of Personal Computers (PC), came Local AreaNetworks (LANS), forever changing the way in which we look at networked systems.LANS originally consisted of just PC's connected into groups of computers, but soonafter, there came a need to connect those individual LANS together forming what isknown as a Wide Area Network, or WAN, the result was a complex connection ofcomputers joined together using various types of interfaces and protocols. Figure 2shows a modern day WAN. Last year, a survey of Fortune 500 companies showed that15% of their total computer budget, 1.6 Million dollars, was spent on networkmanagement (Rose, 115). Because of this, much attention has focused on two familiesof network management protocols: The Simple Network...

A basic connection is used for short and urgent management message. And a primary connection is used for delay-tolerant management messages. The secondary connection is used for IP summarized management messages such as dynamic host configuration protocol [DHCP], and simple network management protocol [SNMP]. Transport connections can be provisioned or can be recognized on demand. They are used for user traffic flows. Unicast or multicast can be used for transmission.
