而且,由於計算機在網路社會已經浸透到人們生活的各個領域,人們出於種種目的,將隱私自覺地(作為其他功能性信息的一部分寫入計算機,如網上購物時的家庭地址、電話等)或不自覺地(人們在正常利用計算機時,並未意識到自己將有隱私的記錄留在計算機里,如個人信件、日記等)暴露在網上,為擅自闖入者留下了侵權的可能。The directional routing protocol ds _ dsr put forward by the author is the improvement of the current protocol dsr, complete routine discovery and maintenance by directional neighbor nodes routing table, source routing and directional steering. the research discovers the application of the directional antenna, compare the omnidirectional antenna can increases the networks " total throughput, obviously reduces the co _ channel interference ( cci ), multiple access interference ( mai ), enlarges the nodes " signal and interference to noise ratio ( sinr ), and because of the high gain of directional antenna can realize the communication with farther distance and less jump, end to end delay can decrease deeply, simultaneously, security of networks can be improved partially, the node energy also can be saved easily by power control
本文提出的定向路由協議ds _ dsr是基於對現有協議dsr的改進下實現的,通過定向鄰節點路由表、定向源路由和定向搜索來完成路由發現與維護。研究發現,定向天線的應用,相比全向天線可明顯提高網路的總的吞吐量,減少通道干擾、多址干擾,提高信干噪比,且由於定向天線的高增益可實現較遠距離、較少跳數的通信,減少了路由發現時間,這樣大大減小了傳輸時延,網路的整體性能得到了不同程度的提高,同時部分地解決安全問題,通過功率控制還可較容易的實現節能的目的。Socket function mainly realizes setting up and initializing service unit socket, initializing service unit and service unit serial and so on. bind funcion primarily binds local address and port for the socket. listen function is to evaluate the max length of server ’ s listening queue. connect function and accept function set aside rate ahead, infrom user ’ s request of establishing virtual circuit to suna, cooperate with suna to establish the connection between client and server, return the result. we make use of three handshake with data protocol and virtual circuit mode, in this way, when we translate data, we can look up communication course according to virtual circuit number, at the same time, there aren ’ t source ip address and port, end ip address and port in the head of data package, the speed of translating data advances in a certain extent. send function and recv function is to send data collaborating with suna, and copy data from the receiving queue of socket to user ’ s buffer. close function cooperate
Socket ( )函數實現創建、初始化服務元套接字,初始化服務元及服務元序列等。 bind ( )函數為套接字綁定本地地址和埠號。 connect ( )和accept ( )函數主要是根據用戶要求預留帶寬,將用戶的建立虛電路請求轉達給服務元網路體系,協作服務元網路體系採用捎帶數據的三次握手協議建立虛電路,並告訴用戶處理結果,一方面,捎帶數據的三次握手協議在一定程度上可提高數據傳輸速度;另一方面,採用虛電路方式,使得數據通信可直接根據虛電路號查找相應的通信進程,而且數據包的包頭中省去了源ip地址、埠號和目的ip地址、埠號,提高了數據傳輸速率。In the internet, the aim host is accessed by the ip address
在internet網路中,必須通過ip地址來訪問目的主機。This paper is mainly studying the technology about the transition of ipv4 network to ipv6 network. we discussed clearly several solutions abut this problem, such as dual stack > tunnel and nat - pt

傳統的音頻系統中,音頻軌道都要與一條音頻電纜相連;多房間、長距離安裝復雜;音頻內容的管理和監控都需要附加硬體設備和電纜;音頻路由需要人工接線或昂貴的音頻路由器,系統的重新配置也是復雜而耗時的過程。 etheraudio音頻路由器可以利用5類線同時傳輸音頻和控制數據;音頻設備可以通過以太網獨立監控;音頻數據可以傳輸到單個或多個目的地;音頻路由可以通過更改地址信息輕易地完成。Article 6 china internet information center is responsible for the management of internet addresses, domain names and catalogues of network resources and shall provide relevant information services
第六條中國網際網路絡信息中心提供網際網路絡地址、域名、網路資源目錄管理和有關的信息服務。In sna, the forwarding of a message unit alonga particular path through a network, as determined by parameters carried in the message unit, such as the destination network address in a transmission header
在系統網路體系結構( sna )中,報文單位沿著特定路徑通過網路的轉發過程,該路徑由報文單位包含的參數(如傳送標題中的目的地網路地址)確定。( 5 ) the definitions, characteristics and all kinds of building algorithms of the voronoi diagram and the delaunay triangle are introduced. their applications in sdm are explored. that the voronoi diagram is an effective method to partition the influence regions between spatial objects and phenomena is put forward, and that the principle of building voronoi diagram is identical to the forming central place is proved
( 5 )系統研究了voronoi圖和delaunay三角網的定義、性質及各種建立演算法,並對它們在空間數據挖掘中的應用進行了探索性研究:提出voronoi圖是界定空間目標(現象)的空間影響范圍的一種行之有效的辦法;從理論上論證了voronoi圖的形成與城市中心地的形成是一致的,提出delaunay三角網是建立城鎮網路體系的最佳模型;研究了利用voronoi圖進行公共設施選址優化的演算法及實現。The purpose of this algorithm is to attempt to prevent non - unique addresses on the network
此演算法的目的是盡量防止網路上出現不唯一的地址。Nowadays, we can attain this goal through information filtering, but only using some simple ways such as keywords filtering, address base filtering, and so on
通過網路信息的過濾無疑可以達到這種目的。但現在採用的主要網路信息過濾方式還是簡單的關鍵詞,地址庫,以及針對協議、埠的過濾方式。Microsoft corp., yahoo inc. and america online inc., among others, are currently trying to retrofit the network so e - mail senders can be authenticated - a way to cut down on junk messages sent using spoofed addresses
微軟、雅虎、美國在線和其它公司目前正嘗試翻新網路系統,使發郵件的人能夠被識別,以此來減少通過偽造地址發送的垃圾郵件。Efm use ordinary ethernet frame to transport oam information but special destination address and type code field, considering epon protocols were standarded last year, most of the network device may not recognize the oam frame above data link layer, so we use linux access link layer method to construct / capture oam frame at l2
Ieee802 . 3ah協議規定使用標準的以太幀作為傳送oam信息的載體,但使用特殊的組播目的地址域和類型/長度域,以區別普通的以太數據。由於協議是2004年剛頒布的,所以現有的網路設備很可能不能識別新的oam幀,這就需要在數據鏈路層對數據包進行捕獲和構造。The new internet technology, mpls forwards data using labels that are attached to each data packet. intermediate mpls nodes do not need to look at the content of the data in each packet
新的網路技術, mpls在每個數據包上加一個標簽,中間的mpls站點只是通過交換標簽來實現數據的傳遞,而不需要關心數據包的實際內容,甚至連目標ip地址也不需要檢查。All the hosts in the ip multicast communication can join or exit from its multicast communication group freely because no matter how many target addresses there are, only one data package can be transferred on one data route
參與ip組播的主機可在任何位置、任何時間加入或退出組播組。組播可以大大的節省網路帶寬,因為無論有多少個目標地址,在整個網路的任何一條鏈路上只傳送單一的數據包。According to the basic principle of tcp / ip and the analysis results, the smtp protocol filtering, the port filtering, the address filtering and the kinds filtering can be achieved. e - mails can beattained by the analysis of the smtp protocol and pop3 protocol. the control on the visiting target address can be implemented by using the filtering system on the e - mails and the analysis on the http protocols
