摘要： A facility is provided in which an ATM switch may operate as a switch in the provision of connection oriented services and operates as a router in the provision of connectionless services. In the router mode, the ATM switch may determine "on the fly" a route which may be used to forward received data cells to an intended destination and then forwards each of the data cells in sequence over the determined route. In the switch mode, the ATM switch operates conventionally and forwards a received data cell over a previously defined switched virtual path. In certain cases, the ATM switch may operate as a router only.

摘要： Disclosed is a location management method for a communication network. In a first embodiment, a procedure for finding an optimal path between a calling switch and a visiting switch node is integrated in the call set up procedure. The connection set up procedure starts by setting up a connection path between the calling switch and the home switch. Then, an “optimal crossover node” is determined along the connection path and then the connection path is cranked back starting from the home switch and moving towards the optimal crossover node. Once the optimal crossover node is reached, the a connection set-up proceeds to set up a connection between the optimal crossover node and the visiting switch. In an alternative embodiment, first a connection is set up between the calling switch and the home switch. Then the connection is extended to the visiting switch either by the call-forwarding or by two-phase crankback method. This results in a quickly routed, but sub-optimal connection. Once the connection extension is completed by call forwarding or by the two phase crankback scheme, the route is optimized by selecting a segment on the sub-optimal connection for route optimization and then utilizing the method of the first embodiment to establish an optimally routed connection.

摘要： In an embodiment, an existing transport protocol connection though a mobile device is recognized as having entered a state of disconnect. A lowest received sequence number is determined from received messages to be transmitted over a disconnected transport protocol connection. A disconnect acknowledgement message with a receive window of zero and a sequence number of one less than the lowest received sequence number is transmitted. The disconnect acknowledge message with a receive window of zero and a sequence number of one less than the lowest received sequence number is continued to be transmitted until the transport protocol connection exits the disconnect state to a connect state.

摘要： Methods and apparatus for implementing proxy Mobile IP in a system implementing multiple VLANs are disclosed. Specifically, a network device such as an Access Point or Foreign Agent supports multiple VLANs on a plurality of interfaces. In addition, the network device implements proxy Mobile IP on at least one interface. The network device ascertains a subnet map of a node, where the subnet map corresponds to a VLAN. It then identifies a Home Agent associated with the subnet map or VLAN via which to register the node. The network device then composes a registration request on behalf of the node, where the registration request identifies the node (e.g., IP address) and includes a Home Agent address associated with the Home Agent. The registration request also directly or indirectly indicates the interface corresponding to the VLAN via which data packets are to be routed. The registration request is then sent on behalf of the node. A registration reply that indicates success or failure of the proxy registration performed on behalf of the node is then received. Upon successful proxy registration, data packets may be transmitted on the VLAN interface of the network device.

摘要： Methods and apparatus for establishing an optimized route between a Mobile Node and a Correspondent Node are disclosed. In particular, a Correspondent Node is notified of the location of a Mobile Node, thereby enabling the Correspondent Node to communicate directly with the Mobile Node. This is accomplished by sending a HOTi message protected in IPSec transport mode from the Mobile Node to a Home Agent associated with the Mobile Node for modification and transmission of a modified HOTi message to the Correspondent Node. The Mobile Node then receives a HOT message protected in IPSec transport mode from the Home Agent associated with the Mobile Node, the HOT message being received from the Home Agent associated with the Mobile Node after modification has been performed by the Home Agent on an initial HOT message received by the Home Agent from the Correspondent Node.

摘要： Various security mechanisms may be used independently, or in combination with one another, to authenticate the identity of a node during the Mobile IP registration process. First, an Access Point receiving a packet from a node verifies that the source MAC address identified in the packet is in the Access Point's client association table. In addition, as a second mechanism, the Access Point ensures that a one-to-one mapping exists for the source MAC address and source IP address identified in the packet in a mapping table maintained by the Access Point. As a third mechanism, a binding is not modified in the mobility binding table maintained by the Home Agent unless there is a one-to-one mapping in the mobility binding table between the source MAC address and the source IP address. Similarly, the Foreign Agent may also maintain a mapping between the source IP address and the source MAC address in its visitor table to ensure a one-to-one mapping between a source IP address and the associated MAC address.

摘要： Methods and apparatus for performing proxy registration on behalf of a node with a Home Agent supporting Mobile IP are disclosed. A first registration request is composed on behalf of the node and transmitted to the Home Agent via a first Local Mobility Anchor, wherein the first Local Mobility Anchor is a regional controller via which registration is performed when the node moves within a region associated with the first Local Mobility Anchor. When the node moves within a region or between regions, the node is re-registered. Specifically, a second registration request is composed and transmitted to the first Local Mobility Anchor when the node moves within the region associated with the first Local Mobility Anchor. When the node moves into a second region associated with a second Local Mobility Anchor and outside the first region associated with the first Local Mobility Anchor, a second registration request is composed and transmitted to the Home Agent via the second Local Mobility Anchor, wherein the second Local Mobility Anchor is a regional controller via which registration is performed when the node moves within a region associated with second first Local Mobility Anchor.

摘要： 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.
