    8、DH), asynchronous transfer mode (ATM), multi-protocol label switching (MPLS), optical transport hierarchy (OTH), Ethernet MAC layer network (ETH) or Ethernet PHY layer network (ETY) server layer networks. This type of service is referred to as Ethernet virtual private LAN (EVP-LAN) service. This Rec

    9、ommendation is based on the Ethernet service framework as defined in Recommendation ITU-T G.8011/Y.1307.

    11、TU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and is

    12、suing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these t

    13、opics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expressi

    14、on “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicabilit

    15、y) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Reco

    16、mmendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability o

    17、f claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this

    18、Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

This type of service is referred to as Ethernet Virtual private LAN (EVP-L

    23、AN) service. This Recommendation is based on the Ethernet service framework as defined in ITU-T G.8011 and is aligned with the EVP-LAN services specified in MEF 6.1.

    45、trated in Figure 6-1. The service is provided over connection oriented server layer networks with a committed information rate (CIR). Note that if a CO-PS server layer is used traffic management is required to ensure that the CIR is maintained. The level of transparency of an EVP-LAN is Frame-based

    46、characteristic information. Some subscribers commonly desire an E-LAN service type to connect their UNIs in a metro network, while at the same time accessing other services from one or more of those UNIs. An example of such a UNI is a subscriber site that wants to access a public or private IP servi

    47、ce from a UNI that is also used to for E-LAN service among the subscribers several metro locations. The Ethernet virtual private LAN (EVP-LAN) service is defined in this clause to address this need. Bundling may or may not be used on the UNIs in the multipoint-to-multipoint EC. As such, CE-VLAN tag
