Abstract
The present invention relates to the handing off without packet loss, from a mobile device traveling from a current point of attachment to a new point of attachment, by providing a copy and forward module in association with the current point of attachment. The copy and forward module copies and stores packets that are being transmitted to a mobile node while the mobile node is in transition from the current point of attachment to the new point of attachment. The copy and forward module maintains a list of addresses as the last known contact addresses of the mobile node, and the mobile node's initial copy request contains an initial contact address of the mobile node. Subsequent copy requests are used to add or delete addresses to the list, and carry a per-address flag to indicate whether the address is to be added or deleted from the list.
