Real-time proxies

摘要

An arrangement for real-time data transmission through data communication networks is disclosed. The arrangement allows for real-time communication between applications located in different internal networks protected by firewalls by means of representing the applications by proxies and establishing TCP channels towards an intermediate proxy server localized outside the firewalls. A set of parameters residing in the server determines i.a. the number of required TCP channels based on the ratio of measured bandwidth between the data flow directions.
