Abstract
A method and apparatus control transmission between a plurality of connectionless servers (CLSs) installed to provide connectionless services on a B-ISDN (Broadband aspects of Integrated Services Digital Network). Customer premises equipments (CPEs) are allocated to the respective CLSs so that the sum of the transmission rates requested by the CPEs allocated to each CLS is substantially equal among the CLSs. A traffic shaper is provided on an output highway in each CLS to shape the traffic so that the traffic does not exceed a predetermined transmission rate for each destination.
Claims18
A method of controlling data transmission between a plurality of connectionless servers to which terminals requesting a connectionless service are allocated, comprising the steps of:
- determining allocation of the terminals so that the sum of the transmission rates requested by the terminals allocated to each connectionless server is substantially equal among the connectionless servers;
- and
- setting up a virtual path between each connectionless server and each of the terminals allocated thereto.
A method of controlling data transmission between a plurality of connectionless servers to which terminals requesting a connectionless service are allocated, comprising the steps of:
- determining a control value for a maximum transmission rate at which data can be transmitted between the connectionless servers;
- and
- performing traffic shaping between the connectionless servers so that the transmission rate of the data transmitted between the connectionless servers does not exceed the control value.
A method of controlling data transmission between a plurality of connectionless servers to which terminals requesting a connectionless service are allocated, comprising the steps of:
- determining a control value for a transmission rate at which data can be transmitted between the connectionless servers;
- and
- performing traffic shaping between the connectionless servers so that the transmission rate of the data transmitted between the connectionless servers does not exceed the control value,
- wherein the connectionless servers and the terminals are connected to an ATM switch that provides virtual paths between the connectionless servers and between each connectionless server and each of the terminals allocated thereto.
An apparatus for controlling data transmission between a plurality of connectionless servers to which terminals requesting a connectionless service are allocated, comprising:
- means for determining allocation of the terminals so that the sum of the transmission rates requested by the terminals allocated to each connectionless server is substantially equal among the connectionless servers;
- and
- means for setting up a virtual path between each connectionless server and a terminal allocated thereto.
An apparatus for controlling data transmission between a plurality of connectionless servers to which terminals requesting a connectionless service are allocated, comprising:
- means for determining a control value for a maximum transmission rate at which data can be transmitted between the connectionless servers;
- and
- means for performing traffic shaping between the connectionless servers so that the transmission rate of the data transmitted between the connectionless servers does not exceed the control value.
An apparatus for controlling data transmission between a plurality of connectionless servers to which terminals requesting a connectionless service are allocated, comprising:
- means for determining a control value for a transmission rate at which data can be transmitted between the connectionless servers;
- and
- means for performing traffic shaping between the connectionless servers so that the transmission rate of the date transmitted between the connectionless servers does not exceed the control value,
- wherein the connectionless servers and the terminals are connected to an ATM switch that provides virtual paths between the connectionless servers and between each connectionless server and each of the terminals allocated thereto.
