Abstract
A Mobile Ethernet Protocol that is used to logically extend a “home VLAN”, through an Ethernet/IP “campus network”, to mobile nodes on “foreign subnets”. The network architecture used for Mobile Ethernet is hierarchical and includes a Subnet Context Manager per subnet and a central Campus Context Manager. The protocol is generally based on the standard Mobile IPv4 protocol, but includes significant extensions to standard Mobile IP including using an 802 address as the permanent MN identifier, rather than an IP address, encapsulating and sending Ethernet frames through IP tunnels, and configuring a single Mobile Ethernet HA to provide access to multiple home VLANs wherein Home VLAN bindings for MNs are dynamically established. A MN does not need to be configured with a permanent IP address.
