A method of controlling routing of packets in a communications network including 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 network address, which routing path is directed to a first access node serving a mobile node using said first network address via a communications link; handing over the communications link of the mobile node, such that a second access node serves said mobile node; and altering said first routing path using a first type of routing update to create a second routing path for said first network address, directed to said second access node: routing packets to said second access node via said second routing path; handing over the communications link of the mobile node, such that a third access node serves said mobile node; and altering routing in said infrastructure using a second type of routing update, different to said first type of update, to create a third routing path for said network address, directed to said third access node, and routing packets to said third access node via said third routing path. |
