Abstract:
A method for initializing a one-way adapter that receives data from a computer network via a first communication path, and communicates with a two-way adapter via a packet processing relay agent, wherein said two-way adapter is adapted to receive data from, and send data to, a service provider of said computer network via a second communication path, comprising the steps of:establishing a link between said two-way adapter and said service provider via said second communication path;obtaining an address from said service provider, and communicating said address to said packet processing relay agent via said second communication path and said two-way adapter;providing a session initialization request packet from said one-way adapter to said packet processing relay agent;said packet processing relay agent providing said session initialization request packet with: (a) a source address according to said address obtained from said service provider, and (b) a destination address of a network address server associated with said first communication path; andcommunicating said session initialization request packet to said network address server via said two-way adapter and said second communication path according to said destination address thereof; wherein:said network address server responds to said packet communicated thereto by communicating address configuration information to said two-way adapter via said second communication path; andsaid packet processing relay agent obtains said address configuration information from said two-way adapter for use in providing initialization of said one-way adapter.
