摘要： Described herein is a method of controlling calls for packet switched networks, each network including at least two local area networks (50, 60) and a connecting network (70). The method comprises the steps of determining an acceptable packet loss rate for a call to be established between two of the local area networks, comparing actual packet loss rate to the acceptable packet loss rate, and dropping the call if the actual packet loss rate is greater than the acceptable packet loss rate. determining for how long a period the actual packet loss rate has been happening and utilising that period in deciding to drop the call. A recorded announcement may be played when the call is to be dropped. Alternatively, the priority of the transmission of the continuous stream of data can be changed when the actual packet loss rate is not acceptable and the above steps are repeated. Ideally, data relating to dropped calls is stored for future use.

摘要： Described herein is a method of controlling call admission for packet switched networks, each network including at least two local area networks (50, 60) and a connecting network (70). The method comprises determining success rates of previous calls from a first local area network to a second local area network and deciding to drop the call attempt based on the success rates of previous calls. In one embodiment, the current packet loss rate for calls from the first local area network to the second local area network is also determined, and the decision to drop the call attempt is based on that current packet loss rate. Additionally, the decision to drop the call attempt may be based on both the current packet loss rate and the success rates of previous calls. It is also possible to transmit a burst of trial data from a first node in the first local area network through the connecting network to a second node in the second local area network, have the burst of trial data received at the second node reflected back to the first node, and to compare the reflected burst of trial data to the transmitted burst of trial data to determine whether transmission of a continuous stream of data can be initiated from the first node in the first local area network to the second node in the second local area network once the reflected burst of trial data has been received at the first node through the connecting network.

摘要： A method of improving the security of computer communications over a connecting network comprising the steps, carried out before a data packet enters the connecting network from a user domain, of tagging the data packet from a user domain with a security level marking and appending the tagged data packet with a string formed from a check-sum made over the data packet and security level marking tag to form a datagram. The integrity of the data is protected and the method can be used to prevent the mis-routing of data packets to user domains of lower security classification.

摘要： Described herein is a method of controlling call admission for packet switched networks, each network including at least two local area networks (50, 60) and a connecting network (70). The method comprises transmitting a burst 5 of trial data of the same size as the packet to be transmitted from a first node (52, 54) in a first local area network (50) to a second node (62, 64) in a second local area network (60) via the connecting network (70). The connecting network (70) comprises a plurality of routing nodes (72, 74, 76, 78, 80) for routing the burst of trial data of the same size as the packet to be transmitted from a first node (52, 54) in a first local area network (50) to second node (62, 64) in a second local area network (60) via the connecting network (70). The connecting network (70) comprises a plurality of routing nodes (72, 74, 76, 78, 80) for routing the burst of trial data to the second node in the second local area network along a particular path. The burst of trial data is reflected by the second node in the second local area network (60) back through the connecting network (70) to the first node in the first local area network (50). A comparison is carried out between the transmitted burst of trial data and the reflected burst of trial data to determine an estimate of packet loss rate of the path, and if the packet loss rate is acceptable a transmission of a continuous stream of data is initiated.
