Abstract: A control system in a communication system comprising a server farm connected by means of Internet Service Provider routers to the Internet or the like. The server farm includes at least a customer WEB server and all server farm resources enabling any user connected to the Internet to access the customer WEB server by using the server farm resources. The server farm includes at least one Service Level Agreement (SLA) server for periodically monitoring the availability of a path to be used by the user to access the customer WEB server.

Abstract: A technique for permitting continued use of IP (Internet Protocol) routing protocols in an Asynchronous Transfer Mode (ATM) network is implemented in each ATM system having route-computing responsibilities. When a call setup request is received, the routing system determines, from the ATM address of the target system, whether a routing protocol must be implemented. If a routing protocol must be implemented, data in an ACN (ATM Cluster Number) field and an HN (Host Number) field in the target ATM address is read and is imported into an IP-format address. This IP-format address is used in implementing the IP routing protocol.
