Metro Packet-Optical Transport 2.0: A Heavy Reading Survey Analysis
Heavy Reading has been tracking metro packet-optical transport systems (P-OTS) since 2007. Since that time, the product segment (as defined by Heavy Reading) has grown from nothing to more than $1.2 billion in equipment sales in 2012.
On the surface, the growth in this segment is impressive. However, in the larger context of the market it was set to replace (the Sonet/SDH segment), P-OTS has not lived up to expectations. In 2012, legacy Sonet/SDH spending was $3 billion – meaning that operators spent three times more on legacy Sonet/SDH gear in 2012 than they spent on metro P-OTS. In this context, we view the era of P-OTS 1.0 (2007-2012) as only moderately successful, as the advent of P-OTS was intended to herald the death of the Sonet/SDH multiservice provisioning platform (MSPP).
We believe that two major factors have limited the growth prospects of metro P-OTS over the past five years:
Heavy Reading believes that we are entering a new era of P-OTS, which we'll call P-OTS 2.0, which seeks to build on the packet shortcomings of the first generation. The excerpt below shows that, as we enter this new phase, P-OTS is finally poised to make the crossover and unseat Sonet/SDH as the dominant form of optical transport in metro and aggregation networks.
- Although packet-optical systems promised to deliver the best of both packet functionality and TDM functionality, many operators did not accept P-OTS systems as truly best of breed in both. Our research over the years showed that operators believed pure-play packet products were superior at packets compared to the P-OTS hybrids on the market.
- Packet technology itself was not ready for prime time as a true replacement for TDM transport – regardless of what platform was used. Packet transport technology and standards needed to evolve and mature as operators were unwilling to sacrifice the reliability, familiarity and TDM efficiency of Sonet/SDH in order to enjoy the lower costs and higher capacities of Ethernet/IP transport. Packet innovations included Synchronous Ethernet (SyncE)/1588v2 timing and synchronization and MPLS-TP OAM, among others.
In this new era, we expect to see the following:
As we enter this new metro P-OTS 2.0 phase, Heavy Reading issued a global operator survey to get a better understanding of operator plans, strategies and perceptions regarding the present state and future of packet-optical transport. Heavy Reading's Fall 2012 Metro Packet-Optical Transport Survey was conducted in November 2012. Respondents were drawn from the network operator list of the Light Reading readership database. A total of 114 service provider respondents participated in the survey.
- The focus of packet-optical shifts from TDM functions to packet functions
- Pure packet implementations of P-OTS begin to ramp and, ultimately, dominate
- Switched OTN enters the metro, removing the need for Sonet/SDH fabrics in new elements
- 100Gbit/s (100G) takes hold in the metro

PRINT EXECUTIVE SUMMARY
In addition to detailed survey results, the report also profiles 12 major suppliers of P-OTS equipment. This includes the 11 suppliers tracked by Heavy Reading in the Packet-Enabled Optical Networking Quarterly Market Tracker, with the addition of carrier Ethernet supplier Juniper Networks, which scored highly in our survey.

There is increasing interest in 100G transport in metro networks, and so, in our survey, we wanted to get a better reading on operator timelines for 100G deployments. We asked operators to select a timeline for wide-scale metro 100G deployments; the results are shown in the excerpt below. The results point to a 100G ramp-up in 2013, with a big bump coming in 2014 (selected by 31 percent of respondents). Only 5 percent of the group reported no plans for 100G, although 19 percent selected "2016 or beyond."
