11.2 Network-to-Network Communications 11.2.1 Methods for assigning an IP address Instructor Note By now the students have probably been convinced of the importance of IP addresses. But an important question about them has been left unaddressed -- how does a host obtain its IP address? Four

11.1 Layer 3 Devices 11.1.1 Routers Instructor Note This target indicator reviews a simple definition of router functionality -- a device which makes best path routing decisions based on layer 3 addressing. The students have just finished studying the dominant Layer 3 Addressing scheme -- IP

10.7 Creating a Subnet 10.7.1 Range of bits needed to create subnets Instructor Note The purpose of this target indicator is to correctly discern how many bits may be "stolen" or "borrowed" from the host fields to extend the network number. The first step in this process is identifying the IP

10.6 Basics of Subnetting 10.6.1 Classical IP Addressing Instructor Note The purpose of this target indicator is to show the wastefulness of classical, classful, non-subnetted IP addressing. The problem may be phrased as follows. A certain amount of large address blocks -- 127 class As -- were

10.5 Reserved Address Space 10.5.1 Purposes for network IDs and broadcast addresses Instructor Note The purpose of this target indicator is to introduce the concept of specially reserved IP addresses. Have the students work out the basic network numbers for all three classes of IP address. For

10.4 IP Address Classes 10.4.1 IP address classes Instructor Note The purpose of this target indicator is that the students recognize class A, B, and C IP addresses. Students should be able to classify IP addresses as A, B, or C. They should also be able to label the octets "network" and "host" as

10.3 IP Addresses within the IP Header 10.3.1 Network layer datagrams Instructor Note The purpose of this target indicator is to subdivide the IP datagram into two major sections: the header information, needed for delivery, and the actual data from the upper layers. World-Wide-Web references are

10.2 Path Determination 10.2.1 Path determination Instructor Note Of course you can make more complicated kinesthetic activities with multiple students acting as multiple routers with multiple paths, but the highway analogy is probably better. In other words, pose the problem to the students -- how

Overview The network layer is responsible for navigating the data through the network. The function of the network layer is to find the best path through the network. The network layer's addressing scheme is used by devices to determine the destination of data as it moves through the network. In

9.7 Range of Equipment for Testing Structured Cabling Projects 9.7.2 Network operation testing Instructor Note The importance of a baseline measurement of network performance is introduced. The baseline is the set of data about your network that you check periodically to ensure the network is still
