Mobile network device multi-link optimizations
First Claim
1. An apparatus, comprising:
- a processor; and
a memory, at least one of the processor or the memory being adapted for;
composing a registration request message including link characteristics;
sending the registration request to a Home Agent, the link characteristics being associated with a link via which the registration request message is sent to the Home Agent;
receiving a registration reply from the Home Agent indicating success or failure of the registration with the Home Agent, wherein the apparatus is a Mobile Router; and
sending an Internet Control Message Protocol (ICMP) source quench message to each node coupled to the Mobile Router, wherein a source IP address of the ICMP source quench message is an IP address of a Correspondent Node.

Abstract
Methods and apparatus for performing optimizations for a mobile network device such as a Mobile Node or Mobile Router supporting multiple links to a Home Agent (or Correspondent Node in a Mobile IPv6 environment) are disclosed. During the registration process, link characteristics are transmitted in the registration request. From the link characteristics, it is possible to determine whether the mobile network device has roamed from a high to a low bandwidth link, or vice versa. A first set of optimizations may be performed when the mobile network device has roamed from a high to a low bandwidth link, while a second set of optimizations may be performed when the mobile network device has roamed from a low to a high bandwidth link. Some optimizations may be performed during the establishment of a TCP session, while others may be performed during or upon completion of the Mobile IP registration process.
