Hybrid security architecture (HSA) provides a platform for middlebox traversal in the network. The HSA decouples the middlebox control from network forwarding. More specifically, such embodiments may receive a data packet having a packet header including an Ethernet header identifying source and destination addresses in the network. A traffic type of the data packet is determined. Then, layer-2 forwarding information, which encodes a set of non-forwarding network service provider middleboxes in the network to be traversed by the data packet, is determined based on the traffic type. The layer-2 forwarding information is inserted into the Ethernet header and the data packet is forwarded into the network. The data packet will then traverse, according to the layer-2 forwarding information, a sequence of the middleboxes in the network, wherein at least one non-forwarding network service will be provided by each of the middleboxes to the data packet in a sequence.

In order to carry out actions such as setting up a call from an entity in the address realm of one middlebox to an entity in the address realm of another middlebox, then a middlebox control node such as a call server is used. Previously, the middlebox control node has needed to have pre-configured information about all the middleboxes and which address realms they are associated with. The present invention provides one or more middlebox-identity-providing nodes which are separate from the middlebox control node, and which are more directly connected to the end users of the service than the middlebox control node. This provides greater flexibility in network design and removes the need for middlebox information to be pre-configured at the middlebox control node. Instead, this information is sent to the middlebox control node, as part of signalling messages, from middlebox-identity-providing nodes.

Accordingly, the home devices connected to the home network through the home gateway can be controlled from the outside irrespective of the middleware supported by the home gateway.

Techniques for managing information in a computing environment. Information associated with components of the computing environment is obtained. Then, from at least a portion of the obtained information, a determination is made as to the existence of one or more relationships associated with at least a portion of the components of the computing environment. The determination of the existence of one or more relationships is capable of accounting for a full lifecycle (e.g., including deployment, installation and runtime) associated with at least one component of the computing environment. Thus, techniques for managing runtime dependencies between the various components of computing systems are disclosed which provide a level of abstraction from individual systems and allow the computation of service / component (wherein the component may, for example, be an application, middleware, hardware, a device driver, an operating system and a system associated with the computing environment) dependencies that are related to end-to-end services, as perceived by a customer. By way of example, the inventive techniques may be applied to a distributed computing environment. The computing environment may also be an autonomic computing environment.

A method is provided to minimize the protocol stacks needed for a short range wireless access point to rapidly communicate a message to a short range wireless mobile device and display it to the user. The short range wireless access point device stores an Access Point Service Indicator (APSI) message characterizing the service platform offerings. The APSI message has a unique message ID in its header. The user device's transport protocol layer is modified to detect the unique message ID and load it into an APSI message buffer. The transport protocol layer passes the APSI message directly to the application layer, bypassing the middleware protocol layers. The method can be applied to communications between various types of wireless devices to enable rapid communication, such as between two mobile devices, between fixed and mobile devices, between short range devices or between long range devices.

A distributed database system has multiple compute nodes each running an instance of a database management system (DBMS) program that accesses database records in a local buffer cache. Records are persistently stored in distributed flash memory on multiple storage nodes. A Sharing Data Fabric (SDF) is a middleware layer between the DBMS programs and the storage nodes and has API functions called by the DBMS programs when a requested record is not present in the local buffer cache. The SDF fetches the requested record from flash memory and loads a copy into the local buffer cache. The SDF has threads on a home storage node that locate database records using a node map. A global cache directory locks and pins records to local buffer caches for updating by a node's DBMS program. DBMS operations are grouped into transactions that are committed or aborted together as a unit.

A method, system, and program for managing failover of J2EE compliant middleware in a high availability system are provided. A primary node and a secondary node each run the same J2EE compliant middleware stack comprising layers including a load balancer, a web server, a web application server, a message control server, a monitoring server, and a database control server. In the primary node, all layers are active. In the secondary node, part of the layers are active and part of the layers are in standby. A data replication partition shared between the primary node and the secondary node includes persistent resource data accessible to a selection of the layers of the primary node. A heartbeat controller monitors each node, including the middleware stack, and upon detection of a failure, controls transfer of the services provided by the primary node to the secondary node by transferring virtual IP addresses from the primary node to the secondary node, remounting the data replication partition for access by the secondary node, and activating the standby layers which require access to the data in the data replication partition.

A method and apparatus for using an intermediary to manage unwanted electronic messages is provided. The intermediary generates a unique address for each pairing of a user and an e-mail resource, such as a mail list. The intermediary maintains a database that identifies which user and which e-mail resource is associated with each unique address. When the intermediary receives messages, the intermediary identifies the user and the e-mail resource based on the database. The intermediary sorts messages for each user based on groups that are associated with each e-mail resource. The intermediary filters the messages to identify messages that are unwanted by the user, such as mass unsolicited e-mail. The intermediary identifies unwanted messages by comparing the sending address for each message to a list of authorized sending addresses for the e-mail resource, and by analyzing the content of the messages, such as identifying whether the messages contain hidden images.

The invention relates to a method, device and system for control of mobile packet flows forwarded between IP based networks. Individual packet flows on an IP user plane (6) traverse middleboxes (13, 14, 23, 24) that are controlled from a midcom agent (15, 21). Each user flow registers its presence (29) in each middlebox it encounters on its way from its source (A) to its destination (B) at the user plane. In response each middlebox registers itself and the mobile flows it handles at the midcom agent with which they communicate using a midcom signalling protocol. The midcom agent comprises functionalities that its controlled middleboxes have and can provide control messages for how a middlebox shall handle a registered flow. The registration provides the midcom agent (15, 21) with knowledge of registered flows and middleboxes which allows the midcom agent to send control orders to the middleboxes that registered themselves, said orders pertaining to the handling of the flows at the respective middleboxes. A mechanism for control signalling at the IP control plane is described.

A computer system, method, and computer program product for controlling data communication in an ad-hoc network that connects a wireless device and a nearby wireless device. The method stores an application directory, determines a priority for each entry in the application directory, identifies a selected entry based on the priority, and examines the attributes and security parameters associated with the selected entry. When the security parameters indicate to use a secure connection, the method establishes a security association to support the data communication by querying a database for an existing security association that will satisfy the security parameters. When the query is successful, the method reuses the existing security association. When the query is unsuccessful, the method creates a new security association by establishing a privileged side channel to the nearby wireless device, negotiating the new security association over the privileged side channel, and storing the new security association.

The present invention envisages a data access, replication or communications system comprising a software application that is distributed across a terminal-side component running on a terminal and a server-side component; in which the terminal-side component and the server-side component (i) together constitute a client to a server and (ii) collaborate by sending messages using a message queuing system over a network Hence, we split (i.e. distribute) the functionality of an application that serves as the client in a client-server configuration into component parts that run on two or more physical devices that commuunicate with each other over a network connection using a message queuing system, such as message oriented middleware. The component parts collectively act as a client in a larger client-server arrangement, with the server being, for example, a mail server. We call this a ‘Distributed Client’ model. A core advantage of the Distributed Client model is that it allows a terminal, such as mobile device with limited processing capacity, power, and connectivity, to enjoy the functionality of full-featured client access to a server environment using minimum resources on the mobile device by distributing some of the functionality normally associated with the client onto the server side, which is not so resource constrained.
