IPv6 Deployment Around The World

Introduction As a first step towards deploying IPv6 (that will co-exist with IPv4) across the Globe, the IPv6 Forum was formed in July 1999. Its common mission is to educate Internet users on the advantages of the IPv6 protocol, and to promote and implement the worldwide deployment of this protocol. It has an impressive membership list comprising of manufacturers, leading Telecom operators, Internet service providers, and vendors of Internet solutions, Consulting companies, R&D institutions and many others. IPv6 The current status of deployment of IPv6 in different parts of the world is very encouraging and gives an idea of...

802.11n Wireless Standard

Posted by admin | Wireless |

Overview IEEE 802.11n is a proposed amendment to the wireless networking IEEE standard 802.11-2007 for improving system performance. The standard 802.11 also referred as Wi-Fi, offers wireless LAN for devices such as laptop computers and cellular phones at home, office, and commercial establishments. The existing standard, 802.11g ratified in 2003 is inadequate due to the complexity of applications and the requirement of more bandwidth. IEEE 802.11n assures higher speed and range. Despite this standard is still in draft stage, it is being implemented by many hardware vendors as “pre-N” or “Draft-N” hardware. As the final version is expected to...

Fixed Mobile Convergence

Posted by admin | Mobile |

Overview Fixed Mobile Convergence (FMC) is the technological convergence of fixed and mobile services. It offers a way to connect a mobile phone to a fixed line infrastructure so that operators can provide services to their users irrespective of their location, access technology, and terminal. FMC enables converged services across the fixed, mobile and internet environments. In FMC, the same handset can access the services through a fixed network in addition to a wireless network. It can be used in home or office and also while traveling. Initially, FMC had too many technical approaches and too few standards. After...

ARP – Address Resolution Protocol

Posted by admin | General |

Overview Address Resolution Protocol (ARP) is a predominant protocol for finding a host’s hardware address when only its network layer address is known. This protocol operates below the network layer as a part of the interface between the OSI network and OSI link layer. It is used when IPv4 is used over Ethernet.Before stepping into the nuances of it lets go through its Frame structure of this protocol. ARP Frame Format and types ARP Packet Format The above fig shows the ARP format used , below is the explanation of each field: Hardware type Each data link layer protocol...

Stateless Auto Configuration

Posted by admin | General |

Introduction Stateless Auto Configuration is an important feature offered by the IPv6 protocol. It allows the various devices attached to an IPv6 network to connect to the Internet using the Stateless Auto Configuration without requiring any intermediate IP support in the form of a Dynamic Host Configuration Protocol (DHCP) server. A DHCP server holds a pool of IP addresses that are dynamically assigned for a specified amount of time to the requesting node in a Local Area Network (LAN). IPv6 Stateless Auto Configuration is a boon for the Network Administrators since it has automated the IP address configuration of...
