Abstract:
1. A method for an organization of network nodes in a packet-switched network, comprising: providing a server having a first server interface and a second server interface; providing a first network node having a first interface and a second interface, the first interface of the first network node being connected to the first server interface; providing a second network node having a first interface and a second interface, the first interface of the second network node being connected to the second server interface; providing a plurality of network elements connected to the first network node via the second interface of the first network node and/or the second network node via the second interface of the second network node; setting the first network node to be a default gateway such that the network elements transmit messages to the server via the first network node; changing the second network node to become the default gateway when at least partial inaccessibility of at least one of the network elements to the server is detected at the first interface of the first network node; performing a check on an interface metric of at least one of the first network node and the second network node after the detection of the at least partial inaccessibility of at least one of the network elements when changing the second network node to become the default gateway; and adapting the interface metric subsequent to and as a consequence of the at least partial inaccessibility of at least one of the network elements to the server via the first network node, the adapting of the interface metric being configured to cause the network elements which would otherwise communicate with the server via the first network node to instead communicate with the server via the second network node to avoid occurrences of asymmetric routing.
