2. Introduction

Today's global communications world has many different definitions for optical transport networks and many different technologies that support them. This has resulted in a number of different Study Groups within the ITU-T, e.g. SG 4, 11, 13, 15 developing Recommendations related to optical transport. Moreover, other standards bodies, fora and consortia are also active in this area.

Recognising that without a strong coordination effort there is the danger of duplication of work as well as the development of incompatible and non-interoperable standards, the WTSA 2000 designated Study Group 15 as Lead Study Group on Optical Technology, with the mandate to:

· study the appropriate core Questions (Question 9, 11, 12, 14, and 16/15),

· define and maintain overall (standards) framework, in collaboration with other SGs and standards bodies),

· coordinate, assign and prioritise the studies done by the Study Groups (recognising their mandates) to ensure the development of consistent, complete and timely Recommendations,

Study Group 15 entrusted WP 5/15, under Question 19/15, with the task to manage and carry out the Lead Study Group activities on Optical Technology. To maintain differentiation from the standardized Optical Transport Network (OTN) based on Recommendation G.872, this Lead Study Group Activity is titled Optical Transport Networks & Technologies (OTNT).

3. Scope

As the mandate of this Lead Study Group role implies, the standards area covered relates to optical transport networks and technologies. The optical transport functions include:

· multiplexing function

· cross connect function, including grooming and configuration

· management functions

· physical media functions.

The outcome of the Lead Study Group activities is twofold, consisting of a:

· standardization plan

· work plan,

written as a single document until such time as the distinct pieces warrant splitting it into two.

Apart from taking the Lead Study Group role within the ITU-T, Study Group 15 will also endeavour to cooperate with other relevant organizations, such as ETSI, Committee T1, ISO/IEC etc.

5. Definitions & Descriptions

One of the most complicated factors of coordinating work of multiple organizations in the area of OTNT are the differences in terminology. Often multiple different groups are utilising the same terms with different definitions. This section includes definitions relevant to this document. See Annex A for more information on how common terms are used in different organizations.

5.1 Optical Transport Networks & Technologies (OTNT)

The transmission of information over optical media in a systematic manner is an optical transport network. The optical transport network consists of the networking capabilities and the technology required to support them. For the purposes of this standardization and work plan, all new optical transport networking functionality and the related technologies will be considered as part of the OTNT Standardization Work Plan. The focus will be the transport and networking of digital payloads over fiber optic cables. Though established optical transport mechanisms such Synchronous Digital Hierarchy (SDH) may fall within this broad definition, only standardization efforts relating to new networking functionality of SDH will be actively considered as part of this Lead Study Group activity.

5.2 Optical Transport Network (OTN)

An Optical Transport Network (OTN) is composed of a set of Optical Network Elements connected by optical fibre links, able to provide functionality of transport, multiplexing, routing, management, supervision and survivability of optical channels carrying client signals, according to the requirements given in Recommendation G.872.

A distinguishing characteristic of the OTN is its provision of transport for any digital signal independent of client-specific aspects, i.e. client independence. As such, according to the general functional modeling described in Recommendation G.805, the OTN boundary is placed across the Optical Channel/Client adaptation, in a way to include the server specific processes and leaving out the client specific processes, as shown in Figure 5-1.

NOTE - The client specific processes related to Optical Channel/Client adaptation are described within Recommendation G.709.

5.3 Metropolitan Optical Network (MON)

A metropolitan optical network is a network subset, often without significant differentiation or boundaries. Therefore an explicit definition is under study. As a result, this section offers more of a description than a formal definition for those who wish to better understand what is commonly meant by “metropolitan optical networks.”

While the existence of metropolitan networks is longstanding, the need for identification of these networks as distinct from the long haul networks in general, as well as the enterprise and access networks is recent. The bandwidth requirements from the end customers have been increasing substantially and many are implementing high bandwidth optical access connections. The resulting congestion and complexity has created a growing demand for higher bandwidth interfaces for inter office solutions. This aggregation of end customer traffic comprises a Metropolitan Optical Network (MON). MONs now have the technology to be optical based and thus, in theory, use the same technology over the fibres as other portions of the network. However, this is not always the case as there are various market forces that drive which technologies will be deployed in which part of the network. As a result, it is appropriate to describe the MON in a way that is agnostic to the various technology approaches. In spite of the many similarities, there are several distinctions between metropolitan and long haul optical networks (LHONs) that result from the aggregation of traffic from enterprise to metro to long haul networks as shown in Figure 5-2.

The first distinction is that MONs are inherently designed for short to medium length distances in metropolitan areas. That is, typically, within the limits of a single optical span and often less than 200km distance. As a result, topics such as signal regeneration, in-line amplification and error correction are of lesser importance than in LHONs.
Secondly, the driving requirement for MONs is maximized coverage commensurate with low cost connectivity (as opposed to grooming for performance with LHONs). As a result, for example, standardization focuses on the adaptation of local area network technologies to be effectively managed by service providers, on ‘insertion loss’ amplification to recover from all the connection points, and on ring deployment to leverage existing fibre plant.
Another key difference is that of service velocity. The demand for fast provisioning results in the circuit churn rate being generally higher in MONs than LHON. That combined with the wider variety of client signals is a key driver for flexible aggregation (e.g., 100Mb-1Gb rate, all 8B/10B formats with one card).
A final distinction is that in the MON there are service requirements (e.g., bandwidth-on-demand services, and multiple classes-of-services) that lead to further topology and technical considerations that are not a priority for LHONs.

While there are many combinations of technologies that can be used in MONs, the following are common examples:

SONET/SDH
DWDM, CWDM
Optical Ethernet
Resilient Packet Ring
APON and EPON

As a result of the importance of MONs, SG15 has redefined several of its Questions work programs to specifically include metro characteristics of optical networks.

7. Overview of existing standards and activity

With the rapid progress on standards and implementation agreements on OTNT, it is often difficult to find a complete list of the relevant new and revised documents. It is also sometimes difficult to find a concise representation of related documents across the different organizations that produce them. This section attempts to satisfy both of those objectives by providing concise tables of the relevant documents.

NOTE: Tables in this section include four digit ITU-T Recommendation numbers in the G. series. These new numbers are directly derived from the three digit versions with a “0” added after the three digit Recommendation number. The four digit numbers are created only in series where space is needed for new documents. The explanation for the current number extensions is captured in Annex C.

7.1 New or Revised OTNT Standards or Implementation Agreements

Many documents, at different stages of completion, address the different aspect of the OTNT space. The table below lists the known drafts and completed documents under revision that fit into this area. The table does not list all established documents which might be under review for slight changes or addition of features.

Three major families of documents (and more) are represented by fields in the following table, SDH/SONET, OTN Transport Plane, and ASON Control Plane. All of the recommendations and standards of these three different families are included in tables in later sections of this document.

8. Overview of existing holes/overlaps/conflicts

Considering the number and diversity of different organizations working on standardising aspects of OTNT, it is inevitable that some areas will be missed. For the same reasons, some aspects will be addressed in multiple groups, resulting in possible conflicts based on different applications, priorities, or technical expertise. These items need to be identified and addressed as appropriate. The following table lists those that have been identified, the recommended action, and the status of that action.

TABLE 8-1/OTNT: Known OTNT Standardization Holes/Overlaps/Conflicts

No.	Issue	Action	Status
1.	NNI requirements documents being developed in the IETF ccamp and ipo working groups in parallel with the ITU-T work on G.807/Y.1302, G.8080, and many other drafts.	Formal communications, Cross-pollination by company representatives	Ongoing collaboration by company representatives
2.	Parallel work by ITU-T on permanent virtual circuit based on NNI with work at IETF work on both switch service based on optical UNI and permanent virtual connections based on optical NNI		Ongoing collaboration by company representatives
3.	10GbE WAN PHY may not interoperate with interfaces developed using STM-64 specifications	Adaptation in draft revision of G.707	CLOSED
4.	IEEE 802.3 Ethernet in the First Mile Study Group addressing work that should utilise Q.2/15 work on physical layer portions of Passive Optical Networks	Communication Statement sent to IEEE 802.3, Q.2/15 selected liaison to help coordinate work	Under study in Q.2/15
5	Metropolitan optical networks being developed independent of established standard interfaces, assuming they are stand-alone networks	Metro optical networks description included in OTNT SWP	CLOSED
6	IaDI standardization has different concepts among the different questions. What is necessary? Is the difference in opinion simply based on different interpretations of the IaDI definition?	Work proposals and discussion in Q.16/15 on IaDI standardization	Under study in Q.16/15
7	OTN Routing and how to deal with physical impairments on logical routing decisions	Proposals reviewed in Q.14/15	Under study in Q.14/15
8	Optical Supervisory Channel (OSC) has slightly different definitions and views of standardization among the different questions. What is necessary?	Proposals considered by Q.12/15 and Q.16/15	Inactive
9	Ethernet (GbE, 10GbE) is supported as a client of the OTN, but is additional standardization required specific to Ethernet?	Liaisons to and from the MEF	Q.12/15 continues work on Transport of Ethernet
10	OTN and ASON Framework Recommendations have been proposed in discussions. G.871 is valid (but out of date) as a framework for OTN. The new Optical Transport Networks & Technology Standardization/Work Plan will provide frequently updated information. Are framework recommendations necessary?	Options considered in Q.19/15	Inactive
11	Optical transport network terminology is inconsistent across the industry and in some cases even across the ITU-T. What about using G.871 as the holder for normative definitions for OTN?	Draft document of optical technology terminology based on G.780, G.872, and G.709 provided by Q.9/15	Q.19/15 working via correspondence between SG15 meetings
12	Characterisation of optical monitoring parameters, which would be required for all-optical networking, remain undefined. Which parameters should be used at an all-optical measurement point, how should they be measured, and how should they be used?	Draft G.optmon being considered in Q.16/15	Under study in Q.16/15 and Q.3/4
13	Multiple ITU-T SG15 questions have discussed the standardization of OTN GCC contents. Is coordination between the questions required?	NO, each group standardize the application within its scope	CLOSED
14	Optical control plane protocols to support ASON are currently being discussed, revised, or defined in several organizations, including ITU-T SG15, the IETF, the OIF, and the ATM Forum.	Formal communications, Cross-pollination by company representatives	Ongoing collaboration by company representatives
15	GFP being considered for multiple applications not fully addressed by the current standardized version. Enhancements for different applications either need to be included in G.7041 or they will likely be captured in other application specific documents, resulting in multiple “versions” of GFP.	Q.2/15 considering modified GFP for PON applications	Coordination between Q.2, 11, and 12/15 required
