Admission control while maintaining latency variations of existing sessions within their limits

A method for admitting new streaming sessions while preventing latency variations of existing sessions from exceeding their respective limits, comprising:

• receiving, by a network comprising at least one switch and at least one processor, a request to establish a new streaming session over a new path, in presence of an existing streaming session which is established over an existing path;
• wherein the new path and the existing path pass through an output port of a switch, and the existing streaming session is associated with a limit for an allowable end-to-end latency variation thereof;
• estimating, before the new streaming session is established, an estimated end-to-end latency variation of the existing streaming session, as if the new streaming session is established over the new path;
• determining, by comparing the estimated end-to-end latency variation with the limit, a determination that the estimated end-to-end latency variation exceeds the limit;
• and
• rejecting the request, based on the determination.
