Definitions

  • the invention relates to a method for addressing messages in a computer network.
  • the types of addresses in such computer networks may reach capacity limits.
  • a change of the address types can then be unavoidable.
  • An example of this is the conversion of addressing in the Internet from so-called IPv4 addressing to IPv6 addressing. From now on, more and more (sub-) networks will have to be upgraded to IPv6 addressing, as most recent estimates suggest that no new IPv4 addresses will be available next year.
  • IPv4 and ⁇ addresses or corresponding subnets for many years to come. Due to the large number of existing installations, a few years, perhaps ten or even twenty years, will pass before the last IPv4 network element is shut down. During this transition period, both types of addresses will have to be used side by side. For certain services, for example based on the Session Initiation Protocol voice and video services (called VVoIP services), there are already converters between the two types of addresses, often in the form of so-called Session Border Controller (SBC) with a so-called integrated media gateway (MGW).
  • SBC Session Border Controller
  • MGW integrated media gateway
  • IPv4 requires routers, checksums each recalculated packet, which represents a further processor load.
  • IPv6 In December 1998, IPv6 officially became the successor of IPv4 with the publication of RFC 2460 on the Standards Track.
  • IPsec An implementation of IPsec within the IPv6 standard. This enables encryption and verifying the authenticity of IP packets. For IPv4, IPsec support is only optional.
  • IPv6 Network Address Translation

This object is achieved by a method or by a product according to one of the independent claims. Advantageous further Formations of the invention form the subject of dependent claims.

  • At least one third network element is a communication terminal which, in addition to its function as a communication terminal, also performs a function as an address converter with respect to messages for which this communication terminal is neither the original sender nor a final recipient.
  • a computer network is a network in which messages are exchanged between network elements by means of addresses.
  • An important example of such a computer network is the Internet, in which messages are exchanged in the form of packets by means of so-called IP addresses between network elements.
  • IP Internet Protocol

  • a network element is to be understood as a device capable of transmitting and / or receiving messages in a computer network.
  • network elements are communication terminals, such as Internet telephones, computers, routers, switches and other network elements required or suitable for operating a computer network.

  • all the data terminals transmit data packets to the (compatible) addresses communicated to them during the connection during the connection, for example IP addresses, where a communication terminal acting as an address converter is the recipient of these data packets, which is the corresponding one Exchanges (for example, IPv4 addresses with IPv6 addresses and vice versa) makes and transmits the data packets to the respective receiving (lying for example in each other IP protocol area) data terminals.
