IP tunnel (original) (raw)
IP 터널(IP tunnel)은 두 인터넷 프로토콜 (IP) 네트워크를 연결하는 대화 채널이다. 이것은 한 네트워크의 패킷을 캡슐화하여 또 다른 네트워크로 전달하는데 사용된다.

| dbo:abstract | IP-to-IP-Kapselung (IP in IP encapsulation, RFC 1853) oder auch Tunneling bezeichnet das Weiterleitungsverfahren für Mobile-IP-Anwendungen. Dabei werden die an einem speziellen Host des Heimatnetzwerkes (Home-Agent) gesendeten IP-Pakete als Nutzdaten eines anderen IP-Pakets verpackt, das im Header die sekundäre IP-Adresse des mobilen Hosts enthält. Die beim Home-Agent ankommenden IP-Pakete werden also nicht gelesen, sondern nur nochmal mit einem weiteren Header versehen und so an das Netzwerk geschickt, in dem sich der mobile Host gerade aufhält. Dabei wird das gekapselte IP-Paket gesendet: * direkt an den mobilen Host (Co Located Care-Of-Address) oder * an den Foreign Agent des Gastnetzwerkes (Foreign Agent Care-of-Address). (de) An IP tunnel is an Internet Protocol (IP) network communications channel between two networks. It is used to transport another network protocol by encapsulation of its packets. IP tunnels are often used for connecting two disjoint IP networks that don't have a native routing path to each other, via an underlying routable protocol across an intermediate transport network. In conjunction with the IPsec protocol they may be used to create a virtual private network between two or more private networks across a public network such as the Internet. Another prominent use is to connect islands of IPv6 installations across the IPv4 Internet. In IP tunnelling, every IP packet, including addressing information of its source and destination IP networks, is encapsulated within another packet format native to the transit network. At the borders between the source network and the transit network, as well as the transit network and the destination network, gateways are used that establish the end-points of the IP tunnel across the transit network. Thus, the IP tunnel endpoints become native IP routers that establish a standard IP route between the source and destination networks. Packets traversing these end-points from the transit network are stripped from their transit frame format headers and trailers used in the tunnelling protocol and thus converted into native IP format and injected into the IP stack of the tunnel endpoints. In addition, any other protocol encapsulations used during transit, such as IPsec or Transport Layer Security, are removed. IP in IP, sometimes called ipencap, is an example of IP encapsulation within IP and is described in RFC 2003. Other variants of the IP-in-IP variety are IPv6-in-IPv4 (6in4) and IPv4-in-IPv6 (4in6). IP tunneling often bypasses simple firewall rules transparently since the specific nature and addressing of the original datagrams are hidden. Content-control software is usually required to block IP tunnels. (en) IP tunnel adalah kanal jaringan komunikasi Protokol Internet (IP) antara dua jaringan komputer yang digunakan untuk transportasi menuju jaringan lain dengan mengkapsulkan paket ini. IP Tunnel sering kali digunakan untuk menghubungkan dua jaringan IP tidak bergabung yang tidak memiliki alamat penjaluran asli (native routing path) ke lainnya, melalui protokol penjaluran utama melewati jaringan transportasi tingkat menegah. Bersama dengan protokol IPsec keduanya kemungkinan digunakan untuk membuat jaringan maya pribadi (Virtual Private Network) antara dua atau lebih jaringan pribadi melewati jaringan umum misalnya internet. Penggunaan umum lainya adalah untuk menghubungkan antara instalsi IPv6 dan IPv4 internet. Dalam melakukan IP tunel, setiap paket IP, termasuk informasi pengalamatan dari sumber dan tujuan jaringan IP, dikapsulasi dengan format paket asali lainnya ke jaringan antara (transit network). Di batas antara jaringan sumber ke jaringan antara serta antara jaringan antara ke jaringan tujuan, gerbang jaringan digunakan untuk membangun titik akhir IP tunnel antar jaringan. Kemudian, titik akhir IP tunnel menjadi penjalur IP asali (native IP routers) yang membuat standar penjalur IP antara jaringan sumber dan jaringan tujuan.

(pt) IP隧道是指一種可在两网络间用网际协议进行通信的通道。在该通道里，會先封装其他网络协议的数据包，之後再传输資訊。 IP隧道经常用於连接两個不是用路由直接連結的IP网络，IP隧道會通过底层路由协议来架构中间传输网络。若IP隧道与两個或多个IPSec一起使用时，可以创建虚拟专用网（Virtual Private Network，VPN），讓二個或多個被公開網路（如因特网）隔開的私有网络彼此访问，另一个主要应用也是目前常用的，讓各IPv6網路隔著IPv4网络上通訊。 在IP隧道中，每个IP包、來源/目的地址信息都被封装在一个数据包中，该数据包用于实际物理网络传递。 在源网络与传输网络的边界，以及传输网络和目的网络的边界，會用网关來建立跨网络的隧道端点（endpoint）。因此，IP隧道端点可以變成本地IP路由器，在源网络与目的网络间建立标准路由。端点會截取通過端点封包的隧道协议报头及报尾，再转换为标准IP格式，与其他来源的数据包一样注入到隧道端点的IP栈（IP stack）上。在这一层上，像IPSec或TLS等封装用协议都被移除了。 IP in IP， 又被称为 ipencap，是将IP协议封装入传输用的IP协议的一个例子，RFC 2003描述此协议。类似的变体有IPv6-in-IPv4隧道 （6in4） 和 IPv4-in-IPv6 隧道（）。 因為防火墙的本质及原始数据报文被隐藏了，IP隧道经常用于绕过简单的防火墙规则，通常需要通过内容控制软件才能对IP隧道进行筛查。 移动IPv4主要有三种隧道技术，它们分别是：IP in IP、最小封装以及通用路由封装。 (zh) IP-туннель — это интернет-протокол (IP) сети, канал связи между двумя сетями.
