Status Analysis And Address Statistic On IPv6 Network

Nowadays, network information course is developing. Network scope islarger and larger, Networks are becoming increasingly complex . As businessusers of the technical support and management platform supporting platform ,The introduction of new, efficient means of communication, the Internet hasbecomeincreasinglyimportantrole.The Internet has experienced explosive development in the past 10 to 15years, connecttothe Internetnetworkatthetimewillbedoubledinlessthanayear. But even this is thepace of development has resulted in the late 1990s toaddress the shortage of IP. For IPv6, which is the greatst advantage of a hugeaddress space. Suited to the characteristics of IP traffic end-to-end IPv6supportahugenumberofusers,alwaysonlinefeatures.Based on the theory and characteristics of the network based on IPv6,First, the characteristics of IPv6 network data structure analysis address thesituation and then focus on IPv6 network analysis and statistics. IPv6 networktheoryto be able to further understand and grasp. Followingthe completion ofamajorresearchpaper:1.UnderstandandgraspthetheoryandcharacteristicsofIPv6.First, the structural composition of IPv6 data packets to understand andgrasp. IPv6 network layer and then the different agreements to analyze thecontents of the agreement and to take every feature and the characteristics ofthedatapackettransmissionandanalysis.2.DevelopmentofIPv6NetworkMonitoringSystemInthesystemdevelopmentwork,thefourmainmodulesinthedesignandrealization of the work completed. Statistics module are: Conversational statestatistics module, Statistics module status protocol, Performance statisticsmodulestatus,Statisticsmoduleaddressesthesituation.(1)Conversationalstatestatisticsmodule Automatic Test Equipment conversation by supporting informationnetwork can be realized by the designated network segment. Conversation onthe type of data packet statistics. Based on the conversation to the networksand network traffic statistics function of the upper packaging agreement. Alsoforthewholenetwork,whichwillprovideavarietyofdifferentoralagreementforstatisticalanalysis. Meanwhile,the receiving packages,thenumberofdifferent conversation,packettransmissionandrelatedbytecountandthetotalnumber of bytes can be used for statistical analysis. According to the basicdefinitionofthehash tabledescribes thestatus of oral applicationofstatisticalmethods to handle hash ICMPv6. IPv6 network address, such as establishingandidentifyingmainframetableindexingprocess.A hash table definition of a string of characters will be converted to afixed length of the numerical value or index, Hash called, also called hashmethod. Due to the shorter hash value faster than the original value of thedatabase search. This method is generally used in the database and build asearchindex,alsousedinvariousdecryptionalgorithms.Set up all of the possible keyword pool reporter for the U (CompleteWorks). Actuallyoccurs (that is, actual storage) keyword set to remember K (|H | |U| much smaller than that). | H | K is a set number of elements. U hash tohash functionis usedto mapthetableT[0..m-1] subscript (m=O(|U|)). Udoto the keyword as a variable, and the calculation result is a function hcorresponding to the storage node addresses. In order to achieve O (1) findtimetoaccomplish.A: Hash:Uâ†'(0,1,2,…, m-1}. usually called to hash function h (HashFunction). Hash function h to be dealt with the role of the subscript iscompressed,sobereducedtomof|U|valuetherebyreducingoverheadspace.B: TisHashTable.C: hash(Ki)(Ki∈U),hash(Ki)ismemoryaddressofkeywordKi.D: Node addresses will be stored according to the hash keys to theprocessisknownashashhashtable. In the hash table in the process of establishingand identifyingmainframeindexing would encounter conflicts. The so-called conflict of two differentkeys, the same hash function, it was mapped to the same table position. Thisphenomenonis knownas conflict or collisions. Thetwokeys tothe conflict asasynonymforhashfunction.Here is a similar method to resolve the conflictzipper.Zipper method:Synonyms are all keys to link nodes in a single chain list.If selected HashMap length m, Hashing may be defined as a component of the indicatorpointed m T[0 .. m-1] pointer array. I hash addresses for all nodes are insertedinto a single indicator for the first T[i] Linklist. T in the air, shall be the initialtarget weight. In zipper law, the loading can be more than one factor, butgenerallyα≤1.The methods used in this paper is the difference between law and thezipperisnotdirectlyinthehashtabletobuildasingle-chaintoresolveconflictdifferent IPv6 addresses; It includes line item in the conversation tables. astorage area for IPv6 addresses, In addition to a domain nIndex said aconversation with the same hash address the situation, and whether If there isno will nIndex home to 1, if there were noted in the conversation tables indexThis constitutes a static chain in the conversation tables hash table to resolvetheconflict.(2)Statistics modulestatus protocolStatistics module status protocol can be carried at all of the real-timestatistical agreement.
