The underlying invention generally relates to the field of mobile computing in a wireless mobile networking environment with distributed multimedia applications (130). More specifically, it is directed to the field of Quality-of-Service (QOS) management for adaptive real-time services running on mobile devices and an End-to-End Negotiation Protocol (E2ENP) based on a novel usage of a session-layer protocol (SIP) in conjunction with extensions of a session description protocol implementation (SDP, SDPng) and the Extensible Markup Language (XML) for defining user profile and terminal capability information which allow to enforce and use hierarchical QOS Contract specifications. Thereby, said End-to-End Negotiation Protocol (E2ENP) is applied to derive negotiable information, which enables a prenegotiation, fast negotiation and a fast, dynamic re-negotiation of the end-to-end quality and capabilities for a telecommunication session, for multiple configurations of two or a multiplicity of end peers and/or middleware in a consistent, reliable, and incremental way by enabling the mobile applications to efficiently and timely react to QoS violations. Furthermore, the invention pertains to the concept and realization of a novel E2ENP User Agent (128) which encapsulates the signaling part of E2ENP and expresses the information to be negotiated in an interchangeable format in such a way that heterogeneous applications (130) can easily agree on a reference model applied to orchestrate local, peer, and network resources according to the preferences and profiles of the respective user in a coordinated manner. According to one embodiment of the invention, the employed E2ENP sessionlayer protocol Application Programming Interfaces (101a-e) are independent of the actually used session-layer protocol and session description protocol implementations.

The present invention collects raw packet data related to network traffic flow over the course of time. By combining metadata from the application layer and/or session layer with user and device identity data as well as indicators of a network threat that are received from threat feeds, information concerning pre-existing or post-mortem network incidents may be identified. Based on the nature of a particular network threat and a collective history of network traffic flow over the course of time, analytics may allow for identification of compromised users, files, and network nodes. Such an identification may in turn allow for removal, rehabilitation, or further investigation.

The present invention relates to a method, computer program products, and a computer readable medium, for maintaining communication between a first mobile unit (1) and a second unit (2), where said first unit (1) communicates via a first communications network (A1) and the second unit (2) communicates via a second communications network (A2). The first unit (1) includes a first protocol stack (12) and the second unit (2) includes a second protocol stack (22). The first unit (1) includes a first session layer (11) which is adapted to function as an interface between the first protocol stack (12) and first software components (15) acting within the first unit (1). Similarly, the second unit (2) includes a second session layer (21) which is adapted to function as an interface between the second protocol stack (22) and second software components (25) acting within the second unit (2).

When the first unit (1) switches (A1-3) from a first communications network (A1) to a third communications network (A3), the first session layer (11) functions to maintain communication by selecting first communications hardware (13b) and drive routine (14b) required for the third communications network (A3). The respective identities of the first and second units (1, 2) are maintained by the first and the second session layer (11, 21) and these identities are retained during switching of communications networks by the first unit (1).

A system and method for establishing a secure and authenticated session layer path between user equipment (102) and a security proxy (112), such as a serving call session control function (116). A communications session is established at a user equipment node (102), prior to registering with the security proxy (112). The user equipment (102) subscribes, through the communications session prior to registering with the security proxy (112), to an event package from the security proxy (112). A secure and authenticated session layer path (426) is established, based upon the subscription, through the communications session from the user equipment node to the security proxy (112) and therefore the serving call session control function (116). A session initiation protocol session (442) is originated, at the user equipment node (102), over the secure and authenticated session layer path (426) based upon authentication provided by the secure and authenticated session layer path (426).

A system and a process for a session layer protocol allows a large number of client machines to receive a reliable data stream over inherently unreliable multicast connections in a highly efficient and scalable manner. More specifically, streaming of high-quality video, audio, stock and news tickers, or any other application specific data that requires a reliable data stream is described. The streaming allows for the source to instruct individuals to drop their connection to the stream to prevent noisy individuals from disrupting the operating efficiency of the stream.

At least one network device that moves storage blocks based upon a session layer or higher protocol set is employed to facilitate communication between at least one host and at least one target storage device. The at least one network device may include a server and a switch. Transactions related to data storage access are expressed in a non-network protocol and transmitted via a network protocol data unit across at least a portion of the network by employing encapsulation. An adapter card associated with the data storage unit is employed to extract the non-network protocol transaction. Multiple, mirrored data storage units that are separated by relatively large physical distance may be employed to reduce the likelihood of catastrophic data loss due to an event such as a fire. Further, READ transactions may be facilitated by preloading data storage units with READ metadata for subsequent transmission to a client device to enable expedited access to data stored on the data storage units.

Safe bus devices use a safety protocol in order to transmit safe data encapsulated in an industrial Ethernet message via an Ethernet-based field bus. However, this restricts the safe bus device to a certain combination of safety protocol and industrial Ethernet protocol. In order to be able to use a safe bus device 12, 14, 15₁ more flexibly, it is provided that, to transmit the safety-oriented data, the industrial Ethernet protocol uses the session layer 5 and/or presentation layer 6 of the safety protocol, which is independent of the industrial Ethernet protocol, instead of the session layer 5 and/or presentation layer 6 which is implemented in the industrial Ethernet protocol, whereby such a bus device 12, 14, 15₁ becomes independent of the industrial Ethernet protocol.
