Abstract:
A system and method are shown for load balancing across global network resources using an existing network protocol, such as Mobile IP, having a redirect feature. According to one method, each of a plurality of servers at a data center uses Mobile IP to obtain an IP address that is also provided to a content server site. Further, a content server site includes a plurality of IP addresses assigned to the plurality of servers and creates a load database including load data for each server. When a client request is received at the content server site from a client device, the content server site determines a network address of a server to process the client request based on the load data, and provides the network address of the server to the client device. When the client device receives the network address of the server, the client device sends an application request to the selected server, and the selected server sends an application response to the client device.
Abstract:
A connector system employs a first connector moiety on an insertable miniaturized form factor card. A mobile information device (MID) has a printed circuit board having a second connector moiety with a frame mounted on the MID PCB for receiving the card and having a slot for engagement of an elastomeric connector element in alignment with the second connector moiety. The card is positioned by the frame for alignment of the first connector moiety with the elastomeric connector element. The elastomeric connector element is a single integrated element. The first connector moiety incorporates a plurality of contact pads on the card and the second connector moiety incorporates a like plurality of contact pads on the MID PCB. The contact pads include at least a first set of RF pads and the signals on the first and second connector moieties are arranged for cross talk shielding in the elastomeric connector.
Abstract:
A system and method for providing wireless Internet protocol access is provided. A network entity may be coupled to both a second generation and a third generation network access node. The network entity may intercept a request from a mobile node and determine whether the mobile node desires services from the second or third generation network. The network entity may then establish the proper communication session based on the type of session requested by the mobile node. By employing the network entity, service providers can effectively migrate from the second generation network architecture to the third generation architecture with minimal or no loss of services for users. Also, employing such a network entity enables users to operate a bi-functional mobile node, such as one that requires both second and third generation network access.
Abstract:
Generally speaking, pursuant to these various embodiments, a network element (such as, but not limited to, a gateway) can use (101) a first communication resource to support an application communication session with a first communication platform. By one approach this application communication session is not native to the first communication resource. The network element then uses (102) a second communication resource to at least attempt to extend the application communication session to a second communication platform. By these teachings, when this attempt fails, the network element nevertheless automatically provides (104) a second communication platform application communication session-compatible message to the first communication platform as though the attempt to extend the application communication session to the second communication platform had succeeded.
Abstract:
A method and system of transferring data rate and state information of mobile nodes between access and home networks is provided. A mobile node may register with a foreign agent on a foreign network, by sending mobile node information, such as a data rate at which the mobile node operates and a dormancy status of the mobile node, to a radio access network, which forwards the information to the foreign agent. The foreign agent may then contact a home agent on the mobile node's home network to setup a call. The foreign agent may send the mobile node information, such as the data rate or the dormancy state, to the home agent during call-setup or during the call as well.
Abstract:
A system for live TV transmission over IP networks incorporates a head end real-time encoding/transcoding server for converting live TV encoded data streams with root multicast relay servers receiving multicast data streams from the encoding/transcoding server. The multicast stream output is provided to a first set of relay servers through multicast capable routers and the root multicast servers provide unicast stream output to a second set of relay servers through unicast limited routers. The first and second sets of relay servers provide unicast and multicast stream output for child servers or local access networks.
Abstract:
At least one network element as comprises a part of a communication system maintains (11) a prepaid units account on behalf of each of a plurality of communication system users, wherein the prepaid units correspond to at least one prepaid data communication service. Upon receiving (12) a message from a first communication system user authorizing a transfer of at least some portion of the first communication system user's prepaid units account to a second communication system uesr's prepaid units account, the network element(s) then preferably facilitates (13) a transfer of at least some portion of the first communication system user's prepaid units account to the second communication system user's prepaid units account.
Abstract:
A method and application programming interface for using multiple network addresses on a common physical layer. The host protocol stack supports multiple Internet Protocol interfaces. When a process makes a function call to create a new socket, a new IP address is associated with the socket. Each socket is then bound to an IP address that is distinct from the IP addresses bound to other sockets. This is in contrast to conventional sockets that are bound to a common IP address. In this manner, each process may be associated with a unique IP address. Such a configuration may useful in Internet telephony where each call process receives a unique private IP address in a virtual private network.
Abstract:
A packet data router (300) comprises a central node (200) that is configured and arranged to provide data packet forwarding services but not data packet routing services and a plurality of physically discrete application nodes (301, 302, and 303) that are each operably coupled to the central node wherein each of the application nodes are configured and arranged to provide data packet routing services but not data packet forwarding services.
Abstract:
An apparatus (301) is comprised of a plurality of application cards (302-304) wherein at least a plurality of the application cards each comprise a part, but not all, of a plurality of logical network entities (307 and 308) such as a Packet Data Serving Node. A data packet session manager (305) can serve to manage the allocation and/or usage of one or more session resources (309) by these application cards. In a preferred approach the external interfaces (310) of these application cards are also aggregated and used, in cluster fashion, by each of the logical network entities.
