Cisco Systems introduces IPv6 support on Cisco IOS routers and L3 switches. [21] HP introduces IPv6 with HP-UX 11i v1. [22] On April 23, 2001, the European Commission launches the European IPv6 Task Force [23] 2002: Microsoft Windows NT 4.0 and Windows 2000 SP1 have limited IPv6 support for research and testing since at least 2002.
The implementation of the RPL protocol occurs in wireless sensors and networks, the most used operating system for its implementation is Contiki which is a small open source operating system developed for use in a number of small systems ranging from 8-bit computers to integrated systems on microcontrollers, including sensor network nodes.
There is a difference between a "relay router" and a "border router" (also known as a "6to4 border router"). A 6to4 border router is an IPv6 router supporting a 6to4 pseudo-interface. It is normally the border router between an IPv6 site and a wide-area IPv4 network, where the IPv6 site uses 2002:: / 16 co-related to the IPv4 address used later ...
Many IPv6 routers, such as routers for residential networks, must be configured automatically with no operator intervention. Such routers require not only an IPv6 address for use in communicating with upstream routers, but also an IPv6 prefix for use in configuring devices on the downstream side of the router.
The IPv6 packet header has simplified the process of packet forwarding by routers. Although IPv6 packet headers are at least twice the size of IPv4 packet headers, processing of packets that only contain the base IPv6 header by routers may, in some cases, be more efficient, because less processing is required in routers due to the headers being ...
In the typical case of a home network, for example, the home router uses DHCPv6 to request a network prefix from the ISP's DHCPv6 server. Once assigned, the ISP routes this network to the customer's home router and the home router starts advertising the new address space to hosts on the network, either via SLAAC or using DHCPv6.
An IPv6 packet is the smallest message entity exchanged using Internet Protocol version 6 (IPv6). Packets consist of control information for addressing and routing and a payload of user data. The control information in IPv6 packets is subdivided into a mandatory fixed header and optional extension headers.
The Router Advertisement Daemon is used by system administrators in stateless autoconfiguration(RFC 4862. [ 3 ] ) methods of network hosts on Internet Protocol version 6 networks. When IPv6 hosts configure their network interface controllers , they multicast router solicitation (RS) requests onto the network to discover available routers.
