A meta-debugger receives a first debugging command from a debugger client to set a breakpoint in a first service in a first language and sets the breakpoint in a first native debugger. After receiving a service message invoking the first service, the breakpoint is triggered and the meta-debugger provides to the debugger client a first graphical representation of the first native debugger. The meta-debugger receives a second debugging command from the debugger client, converts the second debugging command into a third debugging command to provide to the first native debugger. After invoking a second service in a second language, the meta-debugger provides to the debugger client a second graphical representation of the second native debugger. The meta-debugger receives a fourth debugging command from the debugger client, converts the fourth debugging command into a fifth debugging command to provide to the second native debugger.

A software package to be installed on a host system may be identified. A service of the host system that is unavailable during an installation of the software package on the host system may be identified where the installation changes a configuration of the service. A determine may be made as to whether the service that is unavailable during the installation of the software package on the host system is being used by a virtual machine (VM) that is associated with the host system. A notification may be provided in view of the determination of the service associated with the software package being used by the VM that is associated with the host system.

A processing device identifies an object that is assigned an object version indicating a modification operation has been performed on the object, and a signature version representing a version of data of the object for which a first signature has been created. The first signature is stored in a data store. The processing device determines whether the object is currently under modification by comparing a value of the object version to a value of the signature version, creates a second signature for the object using the data of the object, responsive to a determination that the object is not under modification, and performs a data integrity analysis on the data of the object by determining whether the first signature matches the second signature.

A method includes receiving, by a mobile device associated with a distributed transaction, a message via a messaging service provided by a mobile network operator. The method further includes determining, by a content based router of the mobile device, that the message is associated with the distributed transaction by determining that the message includes a transaction identifier that corresponds with an entry in a transaction table of the content based router. The entry identifies the distributed transaction and a destination of where to forward the message. The method further includes forwarding, by a processing device of the mobile device, the message to a resource manager resident on the mobile device. The resource manager corresponds to the destination of where to forward the message. The method further includes performing, by the resource manager, an action associated with the distributed transaction in view of contents of the message.

An apparatus and a method for maintaining a file system is described. A method may include receiving a request for allocating a first block of a file system to a file, the first block comprising a first data from the file. The method also includes computing a first hash value by hashing the first data with a first hashing procedure and computing a second hash value by hashing the first data with a second hashing procedure. The method also includes using the first and the second hash values to determine whether a tree structure among a plurality of tree structures has a matching hash value among a plurality of hash values. Each of the plurality of hash values in the tree structure correspond to a block among a plurality of blocks stored in the file system. The method further includes in response to determining that the tree structure has the matching hash value, allocating the corresponding block to the file and updating a reference count of the corresponding block in the tree structure.

A network characteristic of current resources providing a network service may be identified. A determination as to whether the network characteristic of the current resources satisfies a load policy may be made. In response to the network characteristic of the current resources not satisfying the load policy, a new resource may be provisioned to provide the network service a first location associated with the new resource may be transmitted to a server that includes records associated with the network service. Otherwise, when the network characteristic of the current resources satisfies the load policy, an instruction to use an existing record at the server may be transmitted to the server.

Superfluidity is a state in which matter behaves like a fluid with zero viscosity. Our project aims at achieving superfluidity in the network: the ability to instantiate services on-the-fly, run them anywhere in the network (core, aggregation, edge) and shift them transparently to different locations. The SUPERFLUIDITY project tackles crucial shortcomings in todays networks: long provisioning times, with wasteful over-provisioning used to meet variable demand; reliance on rigid and cost-ineffective hardware devices; daunting complexity emerging from three forms of heterogeneity: heterogeneous traffic and sources; heterogeneous services and needs; and heterogeneous access technologies, with multi-vendor network components. The SUPERFLUIDITY solution is based on: a decomposition of network components and services into elementary and reusable primitives; a native, converged cloud-based architecture; the virtualization of radio and network processing tasks; platform-independent abstractions, permitting reuse of network functions across heterogeneous hardware platforms, while catering to the vendors need for closed platforms/implementations; and high performance software optimizations along with leveraging of hardware accelerators. As a result, the 5G network will benefit from: i) location-independence: network services deployable in heterogeneous networks; ii) time-independence: near instantaneous deployment and migration of services; iii) scale-independence: transparent service scalability; and iv) hardware-independence: development and deployment of services with high performance irrespective of the underlying hardware. Through these properties, SUPERFLUIDITY will provide a converged cloud-based 5G concept that will enable innovative use cases in the mobile edge, empower new business models, and reduce investment and operational costs. The SUPERFLUIDITY consortium gathers an impressive and uncommon blend of Telco and IT players that can make its vision a reality.
