Abstract
A call admission control technique allowing flexible and reliable call admissions at an ATM switch in the case of an ATM network including both QoS-specified and QoS-unspecified virtual connections is disclosed. In the case where a QoS (Quality of Service) specified connection request occurs, an estimated bandwidth is calculated which is to be assigned to an existing QoS-unspecified traffic on the link associated with the QoS-specified connection request. A call control processor of the ATM switch determines whether the QoS-specified connection request is accepted, depending on whether a requested bandwidth is smaller than an available bandwidth that is obtained by subtracting an assigned bandwidth and the estimated bandwidth from a full bandwidth of the link.
Claims20
A method comprising:
- receiving, by a device, a connection request;
- determining, by the device, an average bandwidth, on a link associated with the connection request, based on unspecified traffic of an unspecified virtual connection existing on the link associated with the connection request;
- determining, by the device, to accept the connection request based on the average bandwidth on the link associated with the connection request;
- and
- accepting, by the device, the connection request after determining to accept the connection request.
A system comprising:
- one or more processors to:
- determine an average bandwidth, on a link associated with a connection request, based on unspecified traffic of an unspecified virtual connection existing on the link associated with the connection request;
- determine to accept the connection request based on the average bandwidth on the link associated with the connection request;
- and
- accept the connection request after determining to accept the connection request.
A non-transitory computer-readable medium storing instructions, the instructions comprising:
- one or more instructions that, when executed by at least one processor, cause the at least one processor to:
- receive a connection request;
- determine an average bandwidth, on a link associated with the connection request, based on unspecified traffic of an unspecified virtual connection existing on the link associated with the connection request;
- and
- accept the connection request based on the average bandwidth on the link associated with the connection request.
