IPv6 subnetting reference

Abstract: All-optical multifiber networks may require large and expensive optical switches (i.e., optical switches with many inputs/outputs). To tackle this problem, the existing approach adopts an individual node perspective and focuses on designing the internal node architectures that require smaller optical switches (i.e., optical switches with fewer inputs/outputs). In this paper, we adopt an entire network perspective and propose a logical subnetting approach to further reduce the switch size required. We use multiple logical subnets to compose a network, where a subnet has the same physical topology as but smaller dimensions than the network. In each subnet, each node has fewer incoming/outgoing fibers and hence it requires smaller optical switches. A lightpath can be set up through any one of the available subnets. We propose two subnetting methods: (i) homogeneous subnetting in which all subnets are identical and (ii) heterogeneous subnetting in which different subnets may adopt different node architectures and dimensions. Logical subnetting has three advantages: (i) the resulting network requires significantly smaller optical switches, while its blocking probability can be nearly the same, (ii) logical subnetting can complement any existing node architectures to integrate their respective advantages and further reduce the switch size required, and (iii) an existing network can easily be scaled up by adding additional subnets without modifying the existing ones.

Abstract: By doing subnetting, network address can be broken down into several smaller subnets blocks to match the needs of the host address or subnet block. There are several known methods of subnetting ie VLSM and FLSM. In the application example in the case of this research, the results of the analysis indicate that the use of VLSM with a presentation method in terms of effective and efficient by 43% compared to the method of subnetting FLSM. With the same case will try to apply a new technique that is AFLSM. This technique is able to reduce the amount of wasted host better than VLSM, but this technique is not generic and can only be applied in certain cases. This technique also uses a subnet mask pattern is confusing and not in accordance with the standard value of CIDR. To overcome the shortcomings experienced by AFLSM, in this paper proposed a new technique that is HFLSM. HFLSM technique is a technique or a combination of the combined results VLSM and AFLSM. HFLSM techniques using pattern management IP addressing calculation as AFLSM but with a little addition of some rule. While the use of the subnet mask, this technique uses the pattern of use of VLSM subnet mask held that the use of subnet mask IP address will not overlap between the one with the other and the corresponding standard CIDR value. HFLSM more generic when compared with AFLSM, because the application of HFLSM can be done in several different instances. HFLSM also have reduced the ability of IP addresses are wasted or not used better than VLSM in a particular case.

Abstract: The phase teaching model subnetting IPv4 (PTMS-IP4) is an automated system which calculates the subnet of a network. It demonstrates step by step all the stages involved in subnetting. The PTMS-IP4 procedural model, implements the three phases that help the network or internet engineering people to grasp all the steps involved in subnetting. The system first computes the subnet mask into binary. The obtained binary is typically used on the formula 2 n – 2 to calculate both the number of subnets and hosts in a subnet. From the binary mask the ones (1s) are used to determine the number of subnets, whereas the zeros (0s) calculate the number of hosts. Thereafter the PTMS-IP4 calculates the subnet permutations that display the hosts in each subnet. Not only is the system useful as a teaching model, it could also help the network or internet engineers to easily subnet complex networks.

Abstract: This specification defines an extension to the IPv6 stateless address autoconfiguration procedure. New options with meta data are defined that describe the properties and other prefix class meta data associated with the prefix. The stateless address autoconfiguration procedure and end hosts can make use of the additional properties and class information when selecting source address prefixes for a particular uses and use cases. This specification updates RFC4862.
