A method of warning target objects (TOs) of an approaching reference object (RO) includes receiving, by a back-situation awareness function (BSAF) application, RO notification (RON) messages from the RO containing RO related state information, generating, by the BSAF application, a geo-sector (GS) area including a number of GS segments between a current location of the RO and a destination object (DO) specifying a destination location of the RO, calculating, by the BSAF application, for each of the GS segments of the GS area an expected time of arrival (ETA) of the RO at a respective one of the GS segments, and disseminating the calculated GS segment specific ETA values to the TOs.

Method for customized, situation-aware orchestration of decentralized network resources

A method for deploying and instantiating a Management and Orchestration (MANO) instance of a tenant in a data communication network having a Network Function Virtualization Infrastructure (NFVI), wherein a Cloud Service Provider (CSP) provides a centralized MANO framework that manages the NFVI and that orchestrates allocation of resources needed by Network Services (NSs) and/or Virtualized Network Functions (VNFs) configured in the data communication network, includes requesting, by the tenant, provisioning of the MANO instance. The tenant negotiates with the CSP one or more Management Level Agreements (MLAs) which determine scope of autonomy of the tenant over the MANO instance. The tenant receives an allocation of resources of the NFVI and the MANO instance for being employed by the tenant to implement policies of the tenant independently from the centralized MANO framework provided by the CSP.

MLA based distributed management and orchestration (MANO) system and method

A method for enabling (virtualized) application functions ((V)AFs) to associate to underlying (virtualized) network functions ((V)NFs) is provided in a Network Function Virtualization (NFV) environment in which a lifecycle management (LCM) of the (V)AFs and its associations with the underlying (V)NFs and resources are managed by the NFV Management and Orchestration (MANO) system. A service request is validated by an NFV Orchestrator (NFVO) parsing an (V)AF Descriptor ((V)AFD) file within an (V)AF catalogue. An (V)AF Record ((V)AFR) instance is created having information useable to maintain a state and one or more associations of the respective (V)AF. The NFVO, in cooperation with a Virtualized Network Function Manager (VNFM), Virtualized Infrastructure Manager (VIM) and an underlying network controller of the NFV MANO system, establishes the association between the respective (V)AF and the respective underlying (V)NF(s) using the (V)AFD.

The method includes creating, by a system for (virtual) application function and virtual network function management and orchestration, at least one service or service chain that considers or comprises at least one (virtual) network application and/or at least one virtual network function. A virtual application function (VAF) entity is provided as a container for network applications together with a VAF manager (VAFM) for the VAF.

Method and network for managing and orchestrating virtual network functions and network applications

A method for managing computational resources of a data center is useable for making one or more management decisions (MD). One or more computational resources of the data center are assigned to one or more physical and/or virtual functions by MD of a decision making entity (DME). The MD are based on collected performance information of the one or more computational resources. The collected performance information is analysed considering one or more predefined performance parameters. A single performance metric (SPM) is computed representing performance and efficiency of the DME using a result of the analysis. The SPM is used by the DME for making the MD.

A method provides a distributed and granular management and orchestration of virtualized functions (VFs). The method includes instantiating a network function virtualization management and orchestration (NFV-MANO) system that is configured to instantiate micro-functions (MFs) and to link each of the instantiated MFs to a corresponding one of the VFs. Also, a MF of the MFs is instantiated and linked the MF to a VF of the VFs. The instantiated MF is configured to provide at least one service of the NFV-MANO system to the VF to which it is linked. The instantiated MF and the VF are configured to expose interfaces over which they can interface with each other.

A method for operating a data communication network having a Network Function Virtualization Infrastructure (NFVI) includes: by a Cloud Service Provider (CSP), providing a centralized Management and Orchestration (MANO) system that manages the NFVI and that orchestrates the allocation of resources needed by Network Services (NSs) and/or Virtualized Network Functions (VNFs) configured in the network. The method further includes: by the centralized MANO system and upon request from a tenant, allocating resources of the NFVI to the tenant and providing the tenant its own MANO instance for being employed by the tenant to control and manage its own service and/or network slices and/or implement its own policies independently from the centralized MANO framework provided by the CSP. Management Level Agreements (MLAs) negotiated between the CSP and the tenant determine the scope of the tenant's autonomy over the tenant's MANO instance.

A method for providing congestion information in a network is performed in a memory available to a computing entity. A traffic demand is obtained within a certain part of the network by evaluating an amount of traffic in the part of the network per time. A congestion value representing a congestion level of a bottleneck connection link in the network is calculated. The congestion value is a scalar and calculated based on a comparison between measured and/or estimated traffic and traffic demand within a certain part of said network.
