Nowadays, there are thousands of network operators, ranging from long-established national incumbents (who have trusted each other for many years) to small, start-up networks with no track record and no real basis of establishing trust, so new problems that did not exist in the traditional regulated environment are now emerging. It is necessary for operators to know who they are dealing with and the extent to which they can trust other operators to avoid the security problems. Security baseline is the response to this new challenge. The use of this supplement might vary from country to country, according to regulatory regimes. Some regulatory regimes may choose to require that network operators follow the requirements of this supplement. Some network operators may themselves require that other network operators meet certain level of security as a prerequisite to the interconnection. It is recommended that an operator provide telecommunication service for users at the security level that is guaranteed by the implementation of this supplement. The services of higher security level may be provided on customer's demand by the operator at a cost to the former. This supplement is organized into three groups: operator's policy baseline and implementation, technical tools baseline and collaboration baseline. These must be capable of being verified. Evaluation might be conducted by an operator itself as a declaration procedure or with the assistance of the evaluation body through the compliance certification. NOTE – This security baseline includes both technical and management-oriented tools.

This amendment contains additional material to be incorporated into ITU-T Recommendation G.8110.1/Y.1370.1. It presents the architectural aspects of T-MPLS unidirectional point-tomultipoint (p2mp) connections, T-MPLS OAM, T-MPLS survivability and security aspects. The p2mp forwarding plane architecture is based on a profile of the ongoing work in IETF (see Appendix V).

This Recommendation defines the control plane and control protocol interworking procedures for ATM and frame relay connections across an IP/MPLS packet-switched network using pseudo wires. The following items are not within the scope of this Recommendation: • Peer-partition interworking between ATM and frame relay control planes. • Peer-partition interworking between ATM (or frame relay) and IP/MPLS control planes for setting up and managing switched connections between ATM (or frame relay) and IP/MPLS end-points. • L2TPv3 pseudo wires [b-IETF RFC 3931].

This Recommendation defines virtual trunks, their mapping to pseudo wires, and the way ATM switches establish connections through them. The virtual trunk approach provides a mechanism in which pseudo wires function as trunks through which ATM switches can transparently establish and maintain virtual channel connections (VCCs) and virtual path connections (VPCs). This approach has two objectives: • Minimize the amount of interactions between the ATM control plane and the MPLS control plane. • Enable a distributed interworking approach in which ATM control plane and PW control plane may be on different interworking devices. This enables separation of the MPLS network routing domains and the ATM routing domains. The following items are not within the scope of this Recommendation: • Peer-partition interworking between ATM and frame relay control planes. • Peer-partition interworking between ATM (or frame relay) and IP/MPLS control planes for setting up and managing switched connections between ATM (or frame relay) and IP/MPLS end-points. • L2TPv3 pseudo wires [b-IETF RFC 3931]. • Signalling to establish virtual trunks.

This Recommendation specifies a quality of service (QoS) control architecture and requirements covering aspects, such as resource reservation, admission control and gate control, for Ethernet-based IP access networks. Based on the resource and admission control functions (RACF) as defined in [ITU-T Y.2111], this Recommendation provides details specific to Ethernet-based IP access networks. An Ethernet-based IP access network is an IP access network which comprises the Ethernet aggregation network, access nodes, and edge nodes, and may also include the IP aggregation network. In this Recommendation, the Ethernet aggregation network supports VLANs as defined in [b-IEEE 802.1Q] and [b-IEEE 802.1ad]. Note that the QoS mechanisms for the last mile user access segment are MAC technology-specific and as such are out of the scope of this Recommendation.
