Information technology — Fibre Channel — Part 243: Backbone 3 (FC-BB-3)

ISO/IEC 14165-243:2012(E) consists of four distinct Fibre Channel mappings resulting in the following four models: - FC-BB-3_ATM (FC over ATM backbone network); - FC-BB-3_SONET (FC over SONET backbone network); - FC-BB-3_IP (FC over TCP/IP backbone network); - FC-BB-3_GFPT (FC over SONET/SDH/OTN/PDH backbone network using GFPT adaptation).

Overview

ISO/IEC 14165-243:2012 (FC-BB-3) defines the Fibre Channel backbone-3 mappings that enable Fibre Channel (FC) frames to be carried over a variety of transport backbones. The standard specifies four mapping models: FC-BB-3_ATM (FC over ATM), FC-BB-3_SONET (FC over SONET/SDH), FC-BB-3_IP (FC over TCP/IP), and FC-BB-3_GFPT (FC over SONET/SDH/OTN/PDH using GFPT adaptation). It documents reference models, message formats, encapsulation methods, protocol procedures and service considerations needed to interoperate Fibre Channel over wide-area and backbone networks.

Key topics and requirements

• Backbone mappings and reference models for ATM, SONET, IP, and GFPT transports, including functional interfaces (B_Port, VE_Port, SE) and topology models.
• Mapping and encapsulation techniques:
  • AAL5 mapping for ATM,
  • HDLC-like framing for SONET/SDH,
  • TCP/IP encapsulation for IP networks,
  • GFPT adaptation over SONET/SDH/OTN/PDH.
• Message formats and headers (LLC/SNAP, BBW_Header, BBW payload formats) and frame encapsulation guidelines.
• Protocol procedures such as SR and Simple Flow Control (SFC), connection and platform management procedures, error detection/recovery and state machines for link setup/reset.
• Service considerations and quality constraints: latency, timeout values, throughput, reliability, QoS, bandwidth allocation, in-order delivery, payload transparency, and flow control requirements.
• Operational requirements for supporting Fibre Channel classes and handling exceptional conditions and recovery.

Applications and who uses this standard

• Storage architects and SAN designers extending Fibre Channel storage services across metropolitan or long-haul backbone networks.
• Network engineers and systems integrators implementing FC over IP, SONET/SDH, ATM, or transport networks (OTN/PDH).
• SAN and storage equipment vendors building gateways, FC-to-IP/SONET/ATM adaptors, switches and routers that interoperate with existing FC fabrics.
• Telecom carriers and service providers offering managed storage connectivity services that require encapsulation and QoS guarantees.
• Test labs and compliance teams validating interoperability, message formats, and protocol behavior across mixed backbone environments.

Related standards

• Other parts of the ISO/IEC Fibre Channel family and industry transport standards referenced in FC-BB-3 such as TCP/IP, SONET/SDH, OTN/PDH, and ATM protocols.

Keywords: ISO/IEC 14165-243, FC-BB-3, Fibre Channel backbone, Fibre Channel over IP, Fibre Channel over SONET, Fibre Channel over ATM, GFPT, SAN extension, mapping and encapsulation, QoS, flow control.

FOREWORD
1) ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) form
the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate
in the development of International Standards. Their preparation is entrusted to technical committees; any ISO
and IEC member body interested in the subject dealt with may participate in this preparatory work. International
governmental and non-governmental organizations liaising with ISO and IEC also participate in this preparation.
2) In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.
3) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested IEC and ISO member bodies.
4) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted by
IEC and ISO member bodies in that sense. While all reasonable efforts are made to ensure that the technical
content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO cannot be held responsible for the way in
which they are used or for any misinterpretation by any end user.
5) In order to promote international uniformity, IEC and ISO member bodies undertake to apply IEC, ISO and ISO/
IEC publications transparently to the maximum extent possible in their national and regional publications. Any
divergence between any ISO/IEC publication and the corresponding national or regional publication should be
clearly indicated in the latter.
6) ISO and IEC provide no marking procedure to indicate their approval and cannot be rendered responsible for any
equipment declared to be in conformity with an ISO/IEC publication.
7) All users should ensure that they have the latest edition of this publication.
8) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual experts
and members of their technical committees and IEC or ISO member bodies for any personal injury, property
damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees)
and expenses arising out of the publication of, use of, or reliance upon, this ISO/IEC publication or any other IEC,
ISO or ISO/IEC publications.
9) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
10) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
International Standard ISO/IEC 14165-243 was prepared by subcommittee 25: Interconnection of informa-
tion technology equipment, of ISO/IEC joint technical committee 1: Information technology.
A list of all currently available parts of the ISO/IEC 14165 series, under the general title Information
technology – Fibre channel, can be found on the IEC web site.
This International Standard has been approved by vote of the member bodies and the voting results may be
obtained from the address given on the second title page.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

INTRODUCTION
This International Standard specifies mechanisms that allow extension of Fibre Channel links and/or
switched networks across Wide Area Networks. FC-BB-3 defines four distinct Fibre Channel backbone map-
pings: FC over ATM, FC over SONET, FC over TCP/IP, and FC over GFPT.

Part 243: Fibre channel backbone-3 (FC-BB-3)
1 Scope
This part of ISO/IEC 14165-243 consists of four distinct Fibre Channel mappings resulting in the following four
models:
– FC-BB-3_ATM (FC over ATM backbone network)
– FC-BB-3_SONET (FC over SONET backbone network)
– FC-BB-3_IP (FC over TCP/IP backbone network)
– FC-BB-3_GFPT (FC over SONET/SDH/OTN/PDH backbone network using GFPT adaptation)
Figure 1, figure 2, and figure 3 illustrate the scope and the major components of the FC-BB-3 models and its
relationship to the FCIP standard and the ATM Forum/ITU-T standards. Table 1 shows the organization of this
standard. FC-BB-3_IP, FC-BB-3_ATM, FC-BB-3_SONET, and FC-BB-3_GFPT do not interoperate in any way
and are independent models.
