IPv6 Essay Example. Comments (0) Add to wishlist Delete from wishlist. Summary. The header of IPv4 is 20 bits as compared to the 40 bits of IPv6. The advancement in the header allows addition of extension headers, a functionality not provided for by IPv4 computers (Huitema, 1996). Dec 02, 2011 The first header sent defines the minimum needed for an IPv6 packet and also tells if there is an extension header following. This header includes the six fields mentioned above the version, priority, flow label, payload length, and The header of IPv4 is 20 bits as compared to the 40 bits of IPv6.
The advancement in the header allows addition of extension headers, a functionality not provided for by IPv4 computers (Huitema, 1996). The header is composed of a fixed portion length in fixed but the existence of extension headers provides more options for transmitting large packets of data, enhance security and routing options. (Hagen, 2002, pg 16). IPV6 is supposed to replace IPV6 in a few years time especially because the latter faces possible address exhaustion.
Intro to Ipv4& Ipv6 Essay. Assignment 9. Research Paper Introduction to IPv4& IPv6 IPv4 is the fourth version of Internet protocol which uses 32 bit addressing whereas IPv6 is a next generation internet protocol which uses PAGE 22 FIGURES& TABLES FIGURE 1 IPv6 ECOSYSTEM PAGE 6 FIGURE 2 DUALSTACK SUPPORTS BOTH PROTOCOLS IN PARALLEL WITHIN ONE NETWORK PAGE 7 FIGURE 3 EXAMPLE OF A DUALSTACK ACCESS TO THE INTERNET PAGE 14 TABLE 1 IP ADDRESS HEADER FORMATS PAGE 19 TABLE The header length field is eliminated in IPv6 as it is constant for this version (Forouzan, 2003, p 801).
2. The service type field is absent in IPv6. Describe their various advantages and disadvantages (if any), and present network implementation examples using real world examples.
Demonstrate any significant similarities or differences between the two protocols. Your paper should include diagrams and or charts when appropriate (such as headers for example).
(see Figure 1 for example of an IPv6 header) By moving both the nonessential fields and extending headers with optional fields after the IPv6 header itself is how it is achieved. The IPv6 header can be made more efficient by Ipv4 vs Ipv6 connection to the Internet increases because it provides the organization with access to an ever expanding user population.
By referring to the the statistics of the Internet users in the world is 2, 149, 799, 875 and rising in every minute.
