Increasing link throughput to enable admission without exceeding latency variation limits

A method for admitting streaming sessions while controlling links capacities, comprising:

• receiving 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 a link, the link is currently set to have a first capacity, 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, a first end-to-end latency variation of the existing streaming session, supposing that the new streaming session is established over the new path, and the further supposing that the link is set to have the first capacity;
• determining, by comparing the first end-to-end latency variation with the maximum allowable end-to-end latency variation, a first determination that the first end-to-end latency variation exceeds the maximum allowable end-to-end latency variation;
• estimating, before the new streaming session is established, a second end-to-end latency variation of the existing streaming session, supposing that the new streaming session is established over the new path, and further supposing that the link is set to have a second capacity higher than the first capacity;
• determining, by comparing the second end-to-end latency variation with the limit, a second determination that the second end-to-end latency variation does not exceed the limit;
• setting the link to have the second capacity, based on the first and second determinations;
• and
• admitting the request, based on the second determination.
