Abstract:
A network node is provided. The network node includes a component configured to use a value in a Session Initiation Protocol message. The value indicates a supported transport addressing scheme and is used to determine whether to route a related communication session through a transport addressing scheme translation component.
Abstract:
L'invention concerne un procédé de traitement d'une requête de traduction d'un nom de domaine d'une machine B en une adresse IP associée, la requête ayant été émise par une machine A utilisant un premier protocole de communication, la machine B utilisant un second protocole de communication, caractérisé en ce que le procédé comporte les étapes, effectuées par un serveur de résolution, d'obtention (E303, E304) de données d'identification d'un serveur de nom de domaine tiers susceptible de répondre à la requête de traduction, de détermination (E307) du protocole de communication utilisé par le serveur de nom de domaine tiers à partir des données d'identification du serveur de nom de domaine tiers et de transfert (E309, E311) de la requête de traduction au serveur de nom de domaine tiers dans le protocole de communication déterminé.
Abstract:
A data transmission from a first node, such as a user equipment, to a second node, such as an application server or IMS, via a communication network using different types of communication protocols, such as a 3GPP communication network using IPv6 and IPv4, may be controlled by means of a transition mechanism, such as ISATAP. The transition mechanism may be located in the communication network, for example, in a gateway node like a GGSN, which typically acts as a transition mechanism proxy. A data transmission from the first node is commonly forwarded by the network node to the second node wherein the transition mechanism functionality is performed in the network node transparently for the first node.
Abstract:
A method and system for dual network address utilization. The methods and system described herein may help the transition from Internet Protocol version-4 ("IPv4") networks to Internet Protocol version-6 ("IPv6") networks. Dual address allocation on IPv4 (50) and/or IPv6 (88) network addresses is provided via a dual protocol stack. Network devices may communicate with legacy IPv4 networks while using IPv6 network addresses on an IPv6 network for local communications. IPv6 (122) over IPv4 (120) remote virtual tunnels are used to allow network devices using IPv6 network addresses on a local IPv6 network to communicate with remote IPv6 networks over IPv4 public networks (e.g., the Internet). IPv4 (130) over IPv6 (128) local virtual tunnels may be used to allow network devices to using IPv4 network addresses on a local IPv6 network to communicate with remote IPv4 public networks. The IPv4 addresses allocated include IPv4 addresses that may be allocated and used for Distributed Network Address Translation ("DNAT") and/or the Realm Specific Internet Protocol ("RSIP"). The method and system can be used with virtually any set of networks that requires transitions between X-bit and Y-bit network addresses and dual network address utilization.
Abstract:
Bei einem Verfahren zur Adressierung von Nachrichten in einem Computernetzwerk, in dem zwei unterschiedliche Adressenarten verwendet werden, wobei wenigstens ein erstes Netzwerkelement (4, 5, 6, 7, 8) ausschließlich eine erste Adressenart, wenigsten ein zweites Netzwerkelement (14, 15, 16, 17, 18) ausschließlich eine zweite Adressenart und wenigstens ein drittes Netzwerkelement (9, 10, 11, 12, 13, 14) beide Adressenarten verwendet, ist wenigstens ein drittes Netzwerkelement (9) ein Kommunikationsendgerät, welche neben seiner Funktion als Kommunikationsendgerät außerdem eine Funktion als Adressumsetzer in Bezug auf Nachrichten ausübt, für die dieses Kommunikationsendgerät weder der ursprüngliche Absender noch ein letztendlicher Empfänger ist.
Abstract:
It is provided an apparatus, comprising advertisement receiving means adapted to receive an advertisement message according to a first network layer protocol, wherein the advertisement message comprises a flag, a network layer address according to a second network layer protocol different from the first network layer protocol, and a first link layer address; flag detecting means adapted to detect if the flag is set in the advertisement message; routing table setting means adapted to set the first link layer address as a router address in a routing table of the second network layer protocol if the flag is set; and directing means adapted to direct a message of the second network layer protocol to the router address as a first hop router.
Abstract:
A method comprising determining a source bearer for data, determining address information; and processing said data in accordance with a determined source bearer and said determined address information.
Abstract:
The invention relates to a method for the transmission of data between at least two heterogeneous nodes. Said method comprises at least one step for the insertion of an indicator representing at least one address allocated to a user agent (A) included in one of said nodes, into at least one message transmitted (RE(1 ), 1(1 )) by said user agent (A) before the establishment of a communication session between the nodes. The invention enables the rapid identification of the risk of incompatibility between the types of two user agents (A, B) to be brought into communication with each other, with a view to remedying such an incompatibility if necessary. The invention can be applied to the intercommunication of user agents using type IPv4, IPv6 or dual stack (DS) in an IP network.
Abstract:
