MQTTisa Client Server publish/subscribe messaging transport protocol. It is light weight, open, simple, and designed to be easy to implement. These characteristics make it ideal for use in many situations, including constrained environments such as for communication in Machine to Machine (M2M) and Internet of Things (IoT) contexts where a small code footprint is required and/or network bandwidth is at a premium.
ISO/IEC 30111 gives guidelines for how to process and resolve potential vulnerability information in a product or online service.
ISO/IEC 30111 is applicable to vendors involved in handling vulnerabilities.
This document specifies MAC algorithms suitable for applications requiring lightweight cryptographic mechanisms. These mechanisms can be used as data integrity mechanisms to verify that data has not been altered in an unauthorized manner. They can also be used as message authentication mechanisms to provide assurance that a message has been originated by an entity in possession of the secret key.
The following MAC algorithms are specified in this document:
a) LightMAC;
b) Tsudik's keymode;
c) Chaskey-12.
The present document presents an overview of the architecture of the NFV Infrastructure (NFVI) which supports deployment and execution of Virtualised Network Functions (VNFs).
As well as presenting a general overview description of the NFV Infrastructure, the present document sets the NFV infrastructure and all the documents which describe it in the context of all the documents of the NFV. It also describes how the documents which describe the NFV infrastructure relate to each other.
The present document does not provide any detailed specification but makes reference to specifications developed by other bodies and to potential specifications, which, in the opinion of the NFV ISG could be usefully developed by an appropriate Standards Developing Organisation (SDO).
The overall objectives of the ISG NFV were set out in the white paper "Network Function Virtualization", issue 1, 2012 (http://portal.etsi.org/NFV/NFV_White_Paper.pdf) that led to the founding of the ISG and updated in the white paper update "Network Function Virtualization - Update White Paper", issue 2, 2013 (http://portal.etsi.org/NFV/NFV_White_Paper2.pdf).
The present document presents an architectural description of the compute (& storage) domain of the infrastructure which supports virtualised network functions (VNFs). The compute domain includes the network & I/O interfaces required to interface to the infrastructure network and the storage network, if any.
It sets out the scope of the infrastructure domain acknowledging the potential for overlap between infrastructure domains, and between the infrastructure and the virtualised network functions. It also sets out the nature of interfaces needed between infrastructure domains and within the compute domain.
The present document does not provide any detailed specification but makes reference to specifications developed by other bodies and to potential specifications, which, in the opinion of the NFV ISG could be usefully developed by an appropriate Standards Developing Organisation (SDO).
The present document presents the architecture of the Hypervisor Domain of the NFV Infrastructure which supports deployment and execution of virtual appliances. The present document will primarily focus on the use of hypervisor for virtualisation, due to time and resource constraints, However, the hypervisor requirements are similar if not the same for implementing linux containers or other methods for virtualisation.
NOTE: From WikiArch: "Linux Containers (LXC) are an operating system-level virtualisation method for running multiple isolated server installs (containers) on a single control host. LXC does not provide a virtual machine, but rather provides a virtual environment that has its own process and network space. It is similar to a chroot, but offers much more isolation".
There needs to be further research w.r.t to Linux Containers, including developing the ecosystem.

The present document describes how Network Functions Virtualisation (NFV) related interfaces and abstractions are to be derived and specified. It describes the concepts associated with these interfaces and abstractions. It covers the specification process / methodology in general. It presents a cross-cutting framework which covers compute, hypervisor and infrastructure network domains, also data, control and management planes.
The present document does not specify all the interfaces and abstractions as these are covered by other documents, e.g. the NFV INF domain specific documents. Examples of interfaces and abstractions are nevertheless supplied to illustrate the methodology.
The present document does not provide any detailed specification but makes reference to specifications developed by other bodies and to potential specifications, which, in the opinion of the NFV ISG could be usefully developed by an appropriate standards development organization (SDO). Furthermore the NFV INF domain specific documents will not provide detailed specifications either.
The present document enumerates metrics for NFV infrastructure, management and orchestration service qualities that can impact the end user service qualities delivered by VNF instances hosted on NFV infrastructure. These service quality metrics cover both direct service impairments, such as IP packets lost by NFV virtual networking which impacts end user service latency or quality of experience, and indirect service quality risks, such as NFV management and orchestration failing to continuously and rigorously enforce all anti-affinity rules which increases the risk of an infrastructure failure causing unacceptable VNF user service impact. Performance relationships exist between the metrics described in this document and in other specifications such as draft-ietf-ippm-model-based-metrics-02 (work in progress) (February 2014): "Model Based Bulk Performance Metrics", M. Mathis and A. Morton.
The present document does not consider:
The present document describes the management and orchestration framework required for the provisioning of virtualised network functions (VNF), and the related operations, such as the configuration of the virtualised network functions and the infrastructure these functions run on. The objectives are to define this framework, provide requirements for management and orchestration, identify topics that may serve in later gap analysis against current standards, identify best practices and provide guidance on how to address identified new topics. The focus of the present document is on aspects of management and orchestration that are specific to NFV.
The present document addresses the following topics of management and orchestration: architecture framework for management and orchestration of NFV, information elements, interfaces, provisioning, configuration, and operational management, including interworking with existing operations and management systems.
The present document objective is to identify the most common and relevant software architectural patterns present when virtualising network functions and therefore to identify and specify functional requirements necessary to enable such patterns. The information consolidated is reflecting the experience from vendors and operators going through virtualisation of a number of network functions, with a focus on the use case list provided by the NFV Use Cases GS document ETSI GS NFV 001 (V1.1.1): "Network Functions Virtualisation (NFV); Use Cases”.
The present document describes the Network Function Virtualisation abstract software architecture comprising of the following topics:
The present document does not provide any detailed specification. However, the present document makes reference to specifications developed by other bodies, gap, and to potential specifications.
