Method and system for automatic network connection establishment in case of network address renewal

A system for maintaining a connection in a network, comprising:

• a first communication node comprising a first network interface and a second network interface, configured for communication with another communication node on the network;
• and
• a managing module configured for:
• activating the first network interface for obtaining a first network address for communication over the network;
• monitoring the network and determining a first lease time for the first network address;
• and
• activating the second network interface for obtaining a second network address for communication over the network upon approaching end of the lease time, thereby maintaining communication over the network via the second network address.

An apparatus for maintaining a connection in a network, comprising:

• a managing module configured for managing a first network interface and a second network interface in a first communication node for communication with another communication node on the network;
• the managing module comprising:
• a controlling module configured for activating the first network interface for obtaining a first network address for communication over the network;
• and
• a monitoring module configured for monitoring the network and determining a first lease time for the first network address;
• wherein the controlling module is further configured for activating the second network interface for obtaining a second network address for communication over the network upon approaching end of the lease time, thereby maintaining communication over the network via the second network address.
