A method of controlling routing of packets in a connectionless routing protocol network including an infrastructure of packet switching nodes, and a plurality of access nodes to which a routing path, may be directed in said infrastructure for a given network address, said method comprising : routing packets along a first routing path for a first network address, which routin g path is directed to a first access node serving a mobile node; designating a n interface, on which to forward packets arriving along said first routing pat h; altering routing in said infrastructure for said first network address to create a second routing path for said first network address, directed to sai d second access node; altering routing in said infrastructure for said first network address to remove said first routing path not before said second routing path is created; handing over the communications link of the mobile node, such that the second access node serves said mobile node; and routing packets to said second access node via said second routing path. |
