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.

Cloud security is of immediate concern to organisations that must comply with strict confidentiality and integrity policies. More broadly, security has emerged as a commercial imperative for cloud computing across a wide range of markets. The lack of adequate security guarantees is becoming the primary barrier to the broad adoption of cloud computing. The Secure Enclaves for REactive Cloud Applications (SERECA) project aims to remove technical impediments to secure cloud computing, and thereby encourage greater uptake of cost-effective and innovative cloud solutions in Europe. It proposes to develop secure enclaves, a new technique that exploits secure commodity CPU hardware for cloud deployments, empowering applications to ensure their own security without relying on public cloud operators. Secure enclaves additionally support regulatory-compliant data localisation by allowing applications to securely span multiple cloud data centres. Although secure enclaves are a general mechanism, SERECA focuses on a particularly important and rapidly growing class of applications: reactive applications for the Internet of Things (IoT), Cyber-Physical Systems (CPS), augmented reality, gaming, computer-mediated social interaction, and the like. These applications are highly interactive, data intensive, and distributed, often involving extremely sensitive societal and personal information. SERECA is validating its results through the development of two innovative and challenging industry-led use cases. One concerns the monitoring of a civil water supply network, a critical infrastructure targeted by malicious attacks. The other concerns a commercial software-as-a-service (SaaS) application for analysing the performance of cloud-deployed applications. Such a service collects sensitive performance metrics about live usage, assets that must be protected from industrial espionage and other criminal activities.


Methods, systems, and computer program products for providing dynamic batch management of shared packet buffers are disclosed. A virtualized computer system may include a hypervisor with access to memory and executed by a processor to maintain a pool of host memory to store a plurality of incoming network packets received by a network device, adjust a number of memory buffers associated with the pool of host memory to resize the pool of host memory, receive an indication of an incoming network packet stored in the pool of host memory by the network device, and provide the incoming network packet to a guest. In an example, the hypervisor uses the pool of host memory to perform batch processing of the incoming network packets and dynamically adjusts the size of the pool during the processing by adding or removing memory buffers in response to an event, condition, request, etc.


A system, method, and techniques for managing memory are provided. An example method includes identifying a plurality of regions in a heap storing one or more objects of a first type and one or more objects of a second type. Each object of the first type includes application data and management data, and the management data is used by a managed runtime to manage the application data. The method also includes determining an object of the first type to read and computing, based on a last-known memory address of the object of the first type, a memory address of an object of the second type storing a current memory address of the object of the first type. The method further includes reading the current memory address stored in the object of the second type and locating the object of the first type at the read memory address.

Implementations describe hibernating virtual machines (VMs). In one implementation, a method includes receiving, by a first virtual processor of a VM executed by a processing device, an instruction from a sleep-handling module of the VM to invoke a sleep function of a hypervisor executed by the processing device to manage the VM, transmitting, by the first virtual processor of the VM, a request to the hypervisor to put the VM to sleep, wherein the hypervisor, in response to the request, to stop the first virtual processor subsequent to stopping a second virtual processor of the VM, and initiating execution on the first virtual processor and on the second virtual processor responsive to the hypervisor re-starting the first and second virtual processors in response to a wake event.


A server computer system determines that configuring a first virtual machine in a cloud depends on a configuration result of configuring a second virtual machine. The server computer system configures the second virtual machine in the cloud and configures the first virtual machine in the cloud using the configuration result of the second virtual machine.


A computing machine creates a local certificate authority (CA) that has certificate signing authority, creates a certificate signing request (CSR) that includes data of a local service that is hosted by the computing machine, creates a service certificate for the local service using at least a portion of the data in the CSR, signs the service certificate using a private key of the local CA, and provides the service certificate to the local service. The private key is stored locally on the computing machine.


Systems and methods for transmitting encapsulated SNMP commands to virtual machines. An example method may comprise: receiving a Simple Network Management Protocol (SNMP) request; encapsulating, by a processing device, the SNMP request in a format compatible with respect to which a virtual machine is configured to communicate; and providing the encapsulated SNMP request to the virtual machine.
