IPv6- Advantages and Disadvantages
This world is a global village and its protagonists lauds this connectivity in myriad ways. Internet is the main actor when it comes to this global connectivity and here comes the role of t Internet protocols- set of rules governing internet connectivity. Previously ipv4 posed several challenges that were amended with the arrival of this ipv6. However, this new version of internet protocol has its own merit and demerits. The advantages of ipv6 are: more address space to accommodate internet users, SLAAC privacy extensions, added simplified processes, and more security and quality. The list of disadvantages is: more complexity in addresses, incapability issue with machines that have ipv4, and higher costs. This view is highlighted in the ADDIN ZOTERO_ITEM CSL_CITATION {"citationID":"l1rwYqt5","properties":{"formattedCitation":"(Chakravorty, 2008)","plainCitation":"(Chakravorty, 2008)","noteIndex":0},"citationItems":[{"id":15,"uris":["http://zotero.org/users/local/ZD9MNZ2P/items/KCHYI3I4"],"uri":["http://zotero.org/users/local/ZD9MNZ2P/items/KCHYI3I4"],"itemData":{"id":15,"type":"paper-conference","title":"Challenges of IPv6 Flow Label implementation","container-title":"MILCOM 2008 - 2008 IEEE Military Communications Conference","page":"1-6","source":"IEEE Xplore","event":"MILCOM 2008 - 2008 IEEE Military Communications Conference","abstract":"The Internet Protocol version 6 (IPv6) protocol represents an emerging networking capability designed to enhance transport, management and security of IP packets through the networks. IPv6 packet header required for this protocol is much larger than that of the current IPv4 protocol. The processing of IPv6 packets can be complex depending on how many packet header options are needed for a given mode of transmission. There are currently no standards available from Internet Engineering Task Force (IETF), the body that develops all Internet networking standards, related to the use of the flow label. The current IETF standards define the concept of flow of IP packets based on the three tuple of source and destination addresses and the flow label. This definition requires that the bit content of flow label be delivered unmodified at the destination end-system. However, this requirement has its disadvantages in that the network treats the flow label as a component of the fixed bit space of the packet header - not unlike the address bits. This paper discusses an emerging flow label technology called 6LSA and then examines the challenges associated with Flow Label implementation as originally conceived and the advantages of the current state of using the Flow Label.","DOI":"10.1109/MILCOM.2008.4753408","author":[{"family":"Chakravorty","given":"S."}],"issued":{"date-parts":[["2008",11]]}}}],"schema":"https://github.com/citation-style-language/schema/raw/master/csl-citation.json"} (Chakravorty, 2008). Nevertheless, ipv6 is an improved version of the ipv4 and definitely has amended the issue of the previous version but still it is not devoid of some shortcoming. The, challenges related to the flow label are still a part of the latest internet protocol ipv6.
Designing LAN- Some Considerations
Network is a unique and effective way to share digital resources. With the dawn of internet and its increasing complexity, the digital world devised a way to share its resources over a distance and with adequate amount of efficiency. LAN is one such type of network that can manage the limited resources in a better way. It is local area network which requires several significant considerations. It necessitates the harmonious balance between the shared information and the adequate amount of security.

The first part focuses on wide area networks; the second, which is entirely new, focuses on local area networks. Because Ethernet emerged victorious in the LAN war, the second section pays particular attention to Ethernet design and performance characteristics.The volume retains much valuable information from the first edition, and integrates and prominently highlights WAN information that is also relevant to the LAN design process.To maximize the book's utility, the authors include a number of practical networking problems and their solutions, along with examples of methods needed to perform economic comparisons among differing communications services and hardware configurations. The second edition provides a thorough understanding of major network design problems and is an invaluable reference for data communications professionals.","ISBN":"978-1-4398-3223-3","note":"Google-Books-ID: kHFe7wnjKpwC","title-short":"Practical Network Design Techniques, Second Edition","language":"en","author":[{"family":"Held","given":"Gilbert"},{"family":"Jagannathan","given":"S.

In short, the sound knowledge of emergency breakdown is necessary in designing LANs and the adjustment of all hardware and software resources.
