Quality-of-Service Option for Proxy Mobile IPv6
Abstract
This specification defines a new mobility option, the Quality-of-
Service (QoS) option, for Proxy Mobile IPv6. This option can be used
by the local mobility anchor and the mobile access gateway for
negotiating Quality-of-Service parameters for a mobile node's IP
flows. The negotiated QoS parameters can be used for QoS policing
and marking of packets to enforce QoS differentiation on the path
between the local mobility anchor and the mobile access gateway.
Furthermore, making QoS parameters available on the mobile access
gateway enables mapping of these parameters to QoS rules that are
specific to the access technology and allows those rules to be
enforced on the access network using access-technology-specific
approaches.
