Abstract

In a telecommunication network, a method for managing varying traffic load by establishing an instantaneous demand for bandwidth at a pre-defined location of the telecommunication network. The total number of bits required is compared with a number of bits available for use in that pre-defined location, and a bit rate adjusting mechanism is applied to each one of the algorithms associated with an active channels when required. The bit adjusting mechanism is based on pre-defined functions that describe the number of bits that will be allocated for each active algorithm under varying loads of the network. Thus, the bit adjusting mechanism allow the adjustment of the number of bits for each one the network channels, obeying to the constrain that the total number of bits allocated to all channels shall not exceed the total number of bits available.

Dependent claims

A method for managing varying traffic load in a telecommunication network, comprising the steps of:

(i) establishing an instantaneous demand for bandwidth at a pre-defined location of said telecommunication network, by calculating a total number of bits, N, required for delivering transmission by all active channels connected at said pre-defined location of said telecommunication network, wherein said instantaneous demand may arise from more than one type of algorithms, each associated with at least one active channel;
(ii) comparing the total number of bits required N thus obtained, with a number of bits M available for use in said pre-defined location of the telecommunication network;
(iii) applying a bit rate adjusting mechanism to each one of the algorithms associated with the active channels when the number of bits M available for use in said pre-defined location of said telecommunication network is different from the total number of bits N required by all said active channels;
and
(iv) repeating steps (i) to (iii) periodically;
wherein step (iii) is carried out by using the bit rate adjusting mechanism for dropping bits from one or more of the operative algorithms when the number of bits M available for use in the telecommunication network is smaller than the number of bits N representing the network instantaneous demand, and for adding bits to one or more of the operative algorithms if the number of available bits M is greater than the number of bits N representing the network instantaneous demand.
