ICCSA (3) - A VLSM address management method for variable IP Subnetting
Computational Science and Its Applications - ICCSA 2006, 2006Co-Authors: Seongkwon Cheon, Dongxue Jin, Chonggun KimAbstract:IPv6 have been examining at the next IP address standard. But IPv4 have to be used for a while by the following reasons: tremendous cost and efforts for converting to IPv6. One of the serious problems of the IPv4 addressing structure is the fact that is a shortage of IP addresses. The address shortage is derived by lots of unused addresses during IP distribution and IP topic-subnet/">Subnetting design. We propose an effective topic-subnet/">subnet IP address calculation method on VLSM. Also, with the proposed topic-subnet/">subnet IP address management method, a web based topic-subnet/">subnet address management system is introduced. The web-based topic-subnet/">subnet IP management system offers convenience in VLSM-based topic-subnet/">Subnetting. The proposed VLSM calculation method can give a simple and effective IP management.

IP Addressing & Subnetting INC IPV6 - Chapter 8 - Multicast Addressing
IP Addressing & Subnetting INC IPV6, 2000Co-Authors: Cameron Brandon, Ryan Russell, John Pherson, J.d. Wegner, Robert RockellAbstract:This chapter explains that multicast is a great technology that enables a group of computers sharing a multicast address to communicate together. The IP addresses used in multicast are from 224.0.0.0 to 239.255.255.255, defined as Class D addresses. Class E addresses are reserved for future addressing needs. With Internet Group Management Protocol (IGMP ) and multicast topic-routing-protocol/">routing protocols, a network with topic-subnet/">subnets as well as the Internet by the Mbone, can be configured to use and forward multicast packets. Hosts can report they are joining or leaving a group using IGMP. Although a few addresses, like 224.0.0.1 as all-hosts and 224.0.0.2 as all-routers, on the local network are defined in the protocol. IANA is the authority that assigns other multicast addresses. Scoping is an important issue of multicast. The traditional way uses the TTL IP header field to manage the scope, but it has some limitations depending on the need. A new range of multicast addresses have been assigned and defined as Local Scope and Organizational Local Scope to help organizations manage the scope of the topic-multicast-traffic/">multicast traffic. Multicast can be used for effective bandwidth usage, discovery, and efficient channels. IPv6 uses multicast in its core functions and industry is supporting it.

IP Addressing & Subnetting INC IPV6 - Chapter 6 - Routing Issues
IP Addressing & Subnetting INC IPV6, 2000Co-Authors: Cameron Brandon, Ryan Russell, John Pherson, J.d. Wegner, Robert RockellAbstract:This chapter discusses the purpose of routing and the issues that arise from routing in various network environments, from smaller networks to very large, complicated, and dynamic networks such as the Internet. This is evident with the Routing Information Protocol (RIP), which is a very popular topic-routing-protocol/">routing protocol that works beautifully in smaller, less complex networks, but is incapable of performing on a complex network such as the Internet. The threat of IP address exhaustion on the Internet and the concern for large global routing tables with the influx of new networks on the Internet is also discussed. One of the protocols responsible for addressing these issues is Classless Inter domain Routing (CIDR). CIDR can also implement supernetting to aggregate IP addresses into a large block that global routers can use instead of advertising each individual address.

IP Addressing & Subnetting INC IPV6 - Chapter 1 - Addressing and Subnetting Basics
IP Addressing & Subnetting INC IPV6, 2000Co-Authors: Cameron Brandon, Ryan Russell, John Pherson, J.d. Wegner, Robert RockellAbstract:This chapter focuses on addressing and topic-subnet/">Subnetting basics describing solutions for IP address basics, purpose of topic-subnet/">Subnetting, and the basic fixed length Mask. The classful addressing-structure and size of each type is discussed. The chapter highlights the concept of a network along with grouping of addresses. The largest grouping of addresses is the class A group. The next grouping of addresses is the class B group followed by class C group. One task of address management is address assignment. As one begins the process of address allocation, the addresses that are used in the network must be understood. Some devices are assigned a single address for a single interface. Other devices can have multiple interfaces, each requiring a single address. Still other devices have multiple interfaces and some of the interfaces will have multiple addresses otherwise known as multinetting. The purpose of topic-subnet/">Subnetting is discussed in brief here, and, the basic fixed-length mask is explained within the points : what the mask does, components of a mask, binary determination of mask values, decimal equivalent mask values, creating masks for various networking problems, addresses and mask interaction, reserved and restricted addresses, determining the range of addresses within topic-subnet/">subnets, determining topic-subnet/">subnet addresses given a single address and mask, interpreting masks, and finally, reserved addresses.

network Subnetting an instance of technical problem solving in kolb s experiential learning cycle
Hawaii International Conference on System Sciences, 2007Co-Authors: Arnold Kamis, Heikki TopiAbstract:How do we model and improve technical problem solving, such as network topic-subnet/">Subnetting? This paper reports an experimental study that tested three hypotheses, two derived from Kolb's experiential learning cycle and one derived from the advance organizer technique. The two hypotheses following Kolb's cycle were supported, and the one based on advance organizers was not supported. The results indicate that solving network topic-subnet/">Subnetting problems starts concrete, becomes more abstract, and ends concrete. The lack of support for advance organizers indicates that they are not a good fit for technical problem solving, or that they need to be designed differently for it. We draw some implications for research and practice. We also call for additional research to extend Kolb's cycle to other knowledge intensive problem solving domains

Synthesizing Huber’s Problem Solving and Kolb’s Learning Cycle: A Balanced Approach to Technical Problem Solving
The Journal of information and systems in education, 2009Co-Authors: Arnold Kamis, Beverly K. KhanAbstract:1. INTRODUCTION One of the most important skills in Internet Protocol (IP) network design and configuration is topic-subnet/">Subnetting, that is, dividing an IP network into smaller networks in a hierarchy, parts of which can be managed separately. topic-subnet/">Subnetting provides several advantages, such as improved security, ability to manage network resources locally, decreased overall need for unique IP addresses, decreased size of routing tables in core Internet routers, and reduction of broadcast traffic and thus improved utilization of available bandwidth. Without topic-subnet/">Subnetting, it would be impossible to manage organizational IP networks of any significant size. See Kamis and Topi (2007) for a primer on topic-subnet/">Subnetting. Solving topic-subnet/">Subnetting problems requires an in-depth understanding of IP addressing mechanisms. Once grasped, solving a topic-subnet/">Subnetting problem is not difficult, but for less experienced network designers and administrators, it is often a challenge. As most instructors of networking courses can attest, topic-subnet/">Subnetting and troubleshooting of topic-subnet/">Subnetting problems are among of the most difficult challenges for individuals who are new to networking. (Cigas, 2003; Greca, Cook et al., 2004). A substantial stream of research indicates that intensive laboratory practice is necessary for individuals to solve networking problems in general and topic-subnet/">Subnetting problems in particular (Cigas, 2003; Corbesero, 2003; Greca, Cook et al., 2004). With topic-subnet/">Subnetting, as with programming, one cannot solve problems by reading a book or listening to lectures. Research has shown that an active or problem-based learning approach works better (Roussev and Rousseva, 2004; Whittington, 2004). To investigate the solving of topic-subnet/">Subnetting problems, we considered two distinct streams of literature: 1) Kolb's Experiential Learning Cycle (Kolb, 1976; Cook and Swain, 1993; Cornwell and Manfredo, 1994; de Ciantis and Kirton, 1996) with the abstract/concrete distinction (Reeves and Weisberg, 1993a; Reeves and Weisberg, 1993b), and 2) problem solving in general (Newell and Simon, 1972) with emphasis on Huber's approach to problem solving (Huber, 1980). We chose Kolb's cycle because it is a comprehensive and influential model of experiential learning (Kolb, 1976) and because problem solving can be primarily mastered through experiential learning. Kolb's path-breaking work conceived of experiential learning as a four stage cycle, which, ideally, everyone would master. Within his seminal paper, setting that cycle as the ideal, Kolb claimed that few people could master the complete cycle. Instead, he argued that individuals tend to specialize in one of the four stages or styles of learning. Fortunately, organizations could manage an assortment of individuals, who, collectively, would constitute an organizationally balanced "meta-brain". Rather than follow Kolb's conclusions regarding learning styles, however, we focused on Kolb's distinction between abstract and concrete representations of problems and on an individual's movement between these representations as part of the learning process. Reeves and Weisberg have found that learning by analogy increases with the use of concrete rather than abstract representations (Reeves and Weisberg, 1993a; Reeves and Weisberg, 1993b). Sadoski et al (1993) conducted several experiments that showed that concreteness, i.e., the ease of imagery, had strongly positive impacts on comprehension and recall of information (Sadoski, Goetz et al., 1993). [FIGURE 1 OMITTED] Our domain of interest was network topic-subnet/">Subnetting, an instance of technical problem solving. Problem solvers learn a set of rules and apply these to solve a network topic-subnet/">Subnetting problem. Problem solving has been studied in linear, well-structured domains, such as chess (Chase and Simon, 1973; Charness, 1992) and in realistic, complex domains, such as the process control industry (Patrick, Gregov et al., 1999). Studies of problem solving can be descriptive (Srinivasan and Te'eni, 1995) or prescriptive (Patrick, Gregov et al. …
