Nokia Research Center Nokia Research Center This draft describes a solution to perform QoS signaling along the new network path, when mobile node using Mobile IPv6 acquires a new care-of address. The solution is based on the definition of new option called QoS OBJECT OPTION. This option is included in the hop-by-hop extension header of certain packets, preferably the ones carrying binding messages, propagating between mobile node and correspondent node or between mobile node and regional mobility agent(s).
