Network node

摘要

A network node is arranged to provide an end user of a network terminal in a network with an access link to an external network including at least one external network interface, a control unit, and at least one internal network interface, the network node being arranged to be connected between the network and the external network. The network node is characterized in that the control unit is arranged to deactivate and re-activate the at least one internal network interface towards the network terminal in the network in order to trigger a dynamic host configuration protocol request from the network terminal such that a new Internet Protocol configuration can be established for the network terminal. A method for use in a network node and a computer program product are also disclosed herein.

1. A network node arranged to provide a network terminal in a local area network [LAN] with an access link to an external network, comprising:
at least one external network interface coupled to said external network; a control unit; and at least one local area network interface coupled to said network terminal, said network node being arranged between said network terminal and said external network to provide said access link therebetween; wherein said control unit is arranged to deactivate and re-activate said at least one local area network interface connecting said network node to said network terminal in order to trigger a dynamic host configuration protocol [DHCP] request from said network terminal such that a new Internet protocol [IP] configuration can be established for said network terminal, said control unit being arranged to perform said deactivation and re-activation upon said network node detecting a need for providing said network terminal with said new IP configuration including detecting said access link to said external network has switched from one Internet service provider [ISP] with one address domain to another ISP with another address domain.
