    Abstract: A system and method for providing a plurality of client applications access to data in a distributed file system. In various embodiments, read requests are separated from write requests and the read requests are processed by dedicated read servers. A plurality of read servers are coupled to the client applications and each read server reads file data from the distributed file system and returns the file data to the client applications. A write server writes data to the distributed file system. Various embodiments are described for separating read requests from write requests and transmitting read requests to the read servers write requests to the write server.

    Abstract: Methods and apparatus for processing registration requests by a Home Agent supporting Mobile IP are disclosed. A registration request is received from each of a plurality of Mobile Nodes, the registration request specifying a care-of address, which may be allocated by the Foreign Agent. A binding is established between each of the plurality of Mobile Nodes and the associated care-of address, each of the plurality of Mobile Nodes being associated with one another. For instance, the plurality of Mobile Nodes may be statically or dynamically assigned the same Home Address. A tunnel is then created between the Home Agent and the care-of address for each of the plurality of Mobile Nodes, thereby enabling a server request to be distributed by the Home Agent to one of the plurality of Mobile Nodes or to a cluster of Mobile Nodes (e.g., associated with the care-of address) via the associated tunnel. For instance, a server request addressed to the Home Address may be forwarded directly to one of the Mobile Nodes assigned that Home Address. Alternatively, when an address such as the care-of address is associated with multiple Mobile Nodes, the Foreign Agent may perform a second level of dispatching such that the server request is dispatched to one of the Mobile Nodes in the cluster.

    Abstract: A system provides a router node to bridge a LAN and a System Area Network (SAN). The router node distributes LAN traffic across the SAN using a router management agent (RMA) and a filter agent (FA); the RMA includes a session management agent (SMA), a policy management agent (PMA) and a routing agent (RA); the SMA manages connections between remote clients and SAN nodes; the PMA maintains system operation policies; the RA with the FA direct LAN packets to SAN nodes; the FA handles conversion between a SAN protocol and a LAN protocol for packets within the SAN/LAN architecture. The cluster nodes include a node management agent (NMA); the NMA includes an SMA and PMA; these two agents perform the same functions as those in the router node; and a management node sets policies on the router node and includes a monitoring agent to query router node statistics.

    Abstract: Data is routed through the Internet to a mobile node by using home agents and foreign agents to provide mobility functions. Data transfer rates to the mobile node are improved by providing for transfer of data from the home agent to a plurality of foreign agents on a round-robin basis, which can be enhanced by checking the quality of the connection between the foreign agent and the mobile node and re-routing the data through another foreign agent if certain predetermined quality criteria are not met.

    Abstract: The present invention relates to a method for allocating an address of a data service offering server to a communication device such as a mobile services device or a SIM card. With the allocation, the server address is selected from a number of address identifiers. Each address identifier identifies a valid server independently of the current server configuration of the communication network. The server address can be combined out of a fixed and a variable portion. Moreover, the address identifiers can be updated, for example, by means of a so-called DNS server. The described server address allocation method improves the scalability of the communication system and offers an efficient measure for load distribution for both the data service offering application servers and for so-called DNS servers. Moreover, the invention relates to a corresponding communication device for allocating a server address, and to a corresponding communication system and computer program.

    Abstract translation: 本发明涉及一种将数据服务提供服务器的地址分配给诸如移动服务设备或SIM卡的通信设备的方法。 通过分配，从多个地址标识符中选择服务器地址。 每个地址标识符识别与该通信网络的当前服务器配置无关的有效服务器。 服务器地址可以从固定和可变部分组合。 此外，地址标识符可以例如通过所谓的DNS服务器来更新。 描述的服务器地址分配方法提高了通信系统的可扩展性，并为提供应用服务器的数据服务器和所谓的DNS服务器提供了负载分配的有效措施。 此外，本发明涉及用于分配服务器地址的相应通信设备，以及相应的通信系统和计算机程序。
