Allocation of distribution weights to links in a packet network comprising traffic distribution

A method for adjusting distribution weights for a traffic distribution in a packet network to avoid overloading a node, wherein the packet network is made up of nodes and links, and wherein traffic distribution is effected in the packet network with the assistance of distribution fans, the method comprising:

• determining an overall traffic load for outward links originating from the node or for inward links directed to the node;
• verifying whether the overall traffic load in the outward or inward links exceeds a threshold value;
• and
• adjusting distribution weights of links arranged upstream of the node and associated with a distribution fan containing the node if the threshold value is exceeded, such that traffic routed via the node is reduced.

A method for adjusting distribution weights for a traffic distribution in a packet network to avoid an overload in a link, the packet network being made up of nodes and links, and traffic being distributed with the assistance of distribution fans, the method comprising:

• determining an overall traffic load for the link;
• checking whether the overall traffic load exceeds a threshold value;
• and
• adjusting distribution weights of such links associated with a distribution fan containing the link and leading away from the same node if the threshold value is exceeded, such that the traffic routed via the link is reduced.

A method for an overall load verification in a packet network, wherein the packet network is made up of nodes and links, the method comprising:

• determining for every edge node in the network all the traffic entering and leaving the network via the edge node;
• comparing all the traffic entering or leaving via the edge node with the value of a bandwidth of all the links from the edge node or to the edge node multiplied by a factor, said factor representing a number between zero and one;
• and
• aborting the method if all the entering or leaving traffic exceeds the bandwidth.
