The present document specifies the structure and format of a VNF package file and its constituents, fulfilling the requirements specified in ETSI GS NFV-IFA 011 [1] for a VNF package.
The present document specifies a data model for NFV descriptors, using the TOSCA Simple Profile in YAML, fulfilling the requirements specified in ETSI GS NFV-IFA 011 and ETSI GS NFV-IFA 014 for a Virtualised Network Function Descriptor (VNFD), a Network Service Descriptor (NSD) and a Physical Network Function Descriptor (PNFD). The present document also specifies requirements on the VNFM and NFVO specific to the handling of NFV descriptors based on the TOSCA Simple Profile in YAML specification.
The present document provides a contribution to the evolution of network performance testing towards a professional degree of transparency. This begins with a consistent framework of definitions and technical terms. The elements of the testing process are then described within this context.
Apart from the obvious direct parameters of throughput testing, such as time windows or transferred data volumes, there are numerous other elements which can have an impact on data values obtained. In this sense, methodology and definition of metrics cannot be decoupled from each other. The process starts with selecting the boundaries to the system under test, i.e. insertion or demarcation points. Next comes the way the system under test is accessed. For instance, if the test is run over a radio access network using a mobile device such as a smartphone, the type and degree of influence needs to be assessed. The type of stimulus is likewise important, such as the protocol type, the structure of data traffic (e.g. TCP or UDP based), and the number of parallel connections. Depending on these selections, other choices also become parameters for testing. An example would be to use some kind of real application to create a particular type of traffic, versus using synthetically generated traffic.

Ethernet local area network operation is specified for selected speeds of operation from 1 Mb/s to 400 Gb/s using a common media access control (MAC) specification and management information base (MIB). The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) allow use of selected Physical Layer devices (PHY) for operation over coaxial, twisted pair or fiber optic cables, or electrical backplanes. System considerations for multisegment shared access networks describe the use of Repeaters that are defined for operational speeds up to 1000 Mb/s. Local Area Network (LAN) operation is supported at all speeds. Othere specified capabilities include: various PHY types for access networks, PHYs suitable for metropolitan area network applications, and the provision of power over selected twisted pair PHY types.

The maximum Powered Device (PD) power available is increased by this amendment to IEEE Std 802.3-2018 by utilizing all four pairs in the specified structured wiring plant. This represents a substantial change to the capabilities of Ethernet with standardized power. The power classification information exchanged during negotiation is extended to allow meaningful power management capability. These enhancements solve the problem of higher power and more efficient standardized Power over Ethernet (PoE) delivery systems.
Clause 131 through Clause 140 and Annex 135A through Annex 136D are added to IEEE Std 802.3-2018 by this amendment to specify IEEE 802.3 Media Access Control (MAC) parameters, Physical Layer specifications, and management parameters for the transfer of IEEE 802.3 format frames at 50 Gb/s, 100 Gb/s, and 200 Gb/s.
The Management Information Base (MIB) module specifications for IEEE Std 802.3TM, also known as Ethernet, are contained in this standard. It includes the Structure of Management Information Version 2 (SMIv2) MIB module specifications formerly produced and published by the Internet Engineering Task Force (IETF), as well as extensions resulting from amendments to IEEE Std 802.3. The SMIv2 MIB modules are intended for use with the Simple Network Management Protocol (SNMP), commonly used to manage Ethernet.
