Abstract: The present invention relates to an arrangement for improving the service architecture for a compound network, comprising several types of access, as well as comprising parallel service nodes/networks for respective access technologies, and for the purpose of making customer specific adaptations to the service layer more flexible and allowing for a more cost-effective support of access specific protocols and service, it is according to the present invention suggested that said arrangement comprises an open service control protocol allowing support of access specific protocols and services while also allowing the respective access networks to share the same access nodes and service architectures.

Abstract: The present invention relates to an arrangement in connection with supplementary services provided by different vendors, especially the interaction thereof, which supplementary services comprise appropriate standards and protocols, and for the purpose of giving the user a larger ability to influence the supplementary services in question, as well as improving the possibility for vendors to arrive at general standards which are more easy to interpret and which will reduce or eliminate the need of long interoperability tests, it is according to the present invention suggested to use Java as a new media channel, meaning that the arrangement further comprises means for the user to publish service information, advertisements and options to the remote user.

Abstract: The present invention relates to an arrangement a data communication system, wherein users, managers and/or machines (actors) intercommunicate via ports, especially comprising a Transport Service Access Port (TSAP) comprising port number and Internet Protocol (IP) address, which ports communicate through firewalls by means of firewall classification/logic which is controlled by a bastion host therefor, and in order to resolve security issues related to such network, it is according to the present invention suggested that said bastion host is configured to accept digitally signed configuration messages from one of more distributed operator(s) and/or manager(s), for thereby ensuring intergrity of said configuration messages.

Abstract: The present invention relates to connectionless transmission in high speed packet switching networks, and in particular to a group addressing method and system for sending a datagram to one or a plurality of destination nodes and within these nodes for duplicating the datagram and to forward it to multiple end users. The claimed invention takes advantage of a specific data transfer mode called "Remote Access to Functional Addressing" allowing the sending of a datagram to a destination node and within said node, the duplication of said datagram for a transmission towards multiple destinations.
