Blueprint Column: P-OTS... Lessons Learned

By Jimmy Mizrahi

When P-OTS, or packet-optical transport systems, hit the market a few years ago, they brought with them a host of promises for more efficient and cost-effective next-generation transport. The systems were developed to address the increasing share of data and video traffic that’s consuming network bandwidth and capacity and eating away at operators’ profits. Through the integrated packaging of network layers, P-OTS aimed to bring down the cost per bit and reduce the total cost of ownership (TCO) enough to make these rich media services profitable and viable. But P-OTS never managed to deliver on its full potential due to poor execution and unique challenges faced by operators. Fortunately, though, P-OTS taught us all some valuable lessons which are being used to shape the roadmap for a new approach to “beyond next-generation (NG)” transport. 

The Lessons of P-OTS

There are many P-OTS solutions available in the marketplace today, and these platforms utilize a wide variety of architectures and concepts. But none of them quite fit the requirements for true NG transport. Here’s why…  First and foremost, these systems do not provide a real converged solution because they lack full CESR capabilities; in order to support advanced data services, another system must be installed alongside the P-OTS. Next, multiple management systems are needed to support all network layers; this results in higher opex as the technical staff must provision multiple systems rather than a unified system, and there is a greater chance to introduce errors as well. And finally, P-OTS involve a high cost of entry when only part of the solution may be required initially. The reason for these shortcomings is that P-OTS platforms are usually repurposed from vendors’ existing optical or data portfolios and, as a result, they come with inherent compromises. These limitations often lead to higher entry costs, stranded assets, decreased cost efficiency and inefficient OAM – some of the very things that P-OTS endeavored to alleviate.

While P-OTS may have fallen short of delivering on its promises of cost savings and operational simplicity, it did prove to be a step in the right direction conceptually, particularly in the areas of packaging efficiency, multi-layer integration and convergence. Experiences with early P-OTS implementations have provided valuable insight into what a modern telecoms network should look like.

A Roadmap for NG Transport

While P-OTS had some shortcomings, it was a good temporary solution that helped to shape the roadmap for what’s really needed in networks today.

Support for the exponential growth of bandwidth

The amount of data and multimedia traffic that’s traversed networks in recent years has been unparalleled, and this trend shows no signs of slowing down anytime soon. To effectively deal with the rapid growth of bandwidth, a true convergence of network layers is essential.

Reduction in infrastructure costs

Operators don’t want to pay for functionality they’re not using or might never use. To reduce the cost of building and operating networks, a modular and flexible system design is required to provide a low entry cost and pay-as-you-grow scalability for added functionality. 

Alleviation of revenue pressure

Multiple networks mean higher capex and opex and lower revenue per bit. To restore operators’ profitability, Layer 0-3 functionality must be integrated in a single platform to optimize the whole (multi-layered) architecture instead of the individual parts (layers). 

Acceleration of service delivery 

These days, new services have to be turned up more quickly than ever. And existing services need to be easily maintained for maximum efficiency. To simplify and accelerate the introduction and maintenance of new services, a single management system for all network layers is needed to automate the process and save work.

Only a fully integrated multi-layer transport solution can satisfy these roadmap goals and beyond. That solution is the Optimized Multi-Layer Transport (OMLT) platform. 

The OMLT, the First Beyond NG Transport Solution

A highly unique and innovative new breed of transport solution, the OMLT, or Optimized Multi-Layer Transport platform, targets the shortcomings of today’s P-OTS to address operators’ needs and challenges as they introduce new services in a timely and cost-effective way. This “beyond NG” transport solution does this by: 

  • Focusing on the true convergence of the optical and packet layers to reduce the cost of building and operating networks
  • Integrating Layer 0 to Layer 3 functionality in a single platform, making possible the reduction of CAPEX, OPEX and cost per bit 
  • Providing a modular and flexible system design that enables a low entry cost and pay-as-you-grow scalability for added functionality
  • Presenting a single management system for all network layers, allowing new services to be introduced quickly and maintained easily

The fully integrated, multi-layer OMLT addresses operators’ pain points by eliminating integration costs, streamlining procedures and training, reducing network elements and lowering power requirements – with the ultimate goal of reducing TCO, decreasing the cost per bit and making services more profitable. 

Unified Multi-Layer, Multi-System Management

Not only does the OMLT simplify and streamline networks from an architectural perspective, it also does so from a management point of view. Until now, the optical and packet layers had to be configured and managed via several different systems. This was, clearly, a manual and laborious process which held great potential for error, especially when configuring numerous network elements, cards and wavelengths. The OMLT changes all that. 

In contrast to the multiple management systems that were required in the past, the OMLT utilizes a single, unified management system that provides an integrated view across layers, enabling services and the underlying network to be provisioned, managed and tracked end to end. Now, operators can get multiple physical and logical views, making visualization of the connection and correlation between different network layers possible. 

In addition to the unified management system, the OMLT includes a sophisticated planning tool that brings plug-and-play convenience to the planning process, for both equipment and traffic. Whether for greenfield or brownfield installations, the planning tool enables two-way interaction with the management system via an XML (extensible markup language) file that contains configuration information for all network elements, cards, modules and optical attributes, as illustrated here:


This level of optimized, unified network management and plug-and-play planning can save a tremendous amount of time and bring to bear a number of benefits including opex savings, a more efficient use of staff, shorter learning curves and fewer errors.  

Conclusion

While P-OTS failed to deliver on all the promises of operational efficiencies and capex savings, it did provide some valuable lessons learned that shaped a roadmap for the future of next-generation transport networking. That future is the OMLT – a beyond NG transport solution that brings the best of the optical and packet worlds under one platform without compromising on cost or functionality.

Second Two Galileo Satellites Launched

The second two Galileo satellites were launched by Arianespace from French Guiana using Russian-built Soyuz ST vehicle.  The first two Galileo navigational satellites were launched a year ago.

The Galileo global satellite navigation system will consist of 30 satellites and their associated ground infrastructure.  The goal is to have the first 18 satellites in orbit by late 2014, at which point service can begin.  Project completion is expected by the end of the decade.

The Galileo satellites have an orbital altitude of 23,222 km.

The Galileo satellites were built by a consortium with Astrium as prime contractor and Thales Alenia Space in charge of assembly, integration and testing.

The European Commission and the European Space Agency (ESA) have placed orders with Arianespace to launch 22 other satellites in the Galileo constellation using five Soyuz and three Ariane 5 rockets.

“Since the first launch a year ago, Galileo’s technology has proven itself in orbit,” said Didier Faivre, ESA’s Director of the Galileo Programme and Navigation-related activities.  “Thanks to the satellites launched today, the testing phase will be completed, and clear the way for rapid full-scale deployment of the constellation."

Alcatel-Lucent Opens New Conversation with APIs for IMS


Alcatel-Lucent introduced a suite of nine ‘New Conversation APIs’ to help developers access capabilities in service providers'  IP Multimedia Subsystem (IMS) infrastrucuture.

The suite of application programming interfaces (APIs) is aimed at jump starting the ecosystem of companies developing solutions for 4G LTE and IP networks. These capabilities include high definition voice and video, audio/video conferencing, interactive voice, messaging and call control, which can be used to build services for both consumers and businesses.

Alcatel-Lucent said because its new APIs are based on REpresentational State Transfer (REST), a popular, easy-to-use software architecture used to create applications for the Web, developers can more easily create services delivered via IMS.  For service providers, this opens new retail and wholesale revenue opportunities.

Sandip Mukerjee, President of Advanced Communications at Alcatel-Lucent said: “Today, no one else in the marketplace is offering service providers what our New Conversation APIs offer. They enable service providers to fast-track 4G innovation – turning IMS into a real engine for the rapid creation of new services. We make it easy to access the rich features supported by service providers and thereby attract more developers. New applications using IMS-based APIs can be built very quickly, in turn allowing the rapid introduction of more services, and a growth in revenue that comes from our customers being able to differentiate themselves in the marketplace.”

Clearwire Speculation Centers on Spectrum and TD-LTE



Clearwire shares rose 71% on Thursday, as speculation rose that Softbank may bid to acquire the firm. Clearwire is the largest spectrum holder in U.S. and is closely tied with Sprint.

Clearwire operates a nationwide WiMAX network and is planning to make the transition to TD-LTE.  Its main wholesale customer and investor is Sprint, which has extended its 4G agreement through 2015.  The companies have outlined ways of bridging their FD-LTE and TD-LTE networks with dual-mode devices that are under development.  However, Clearwire's CAPEX investments in its network have slowed to a crawl in 2012 as the company conserves cash as it looks for new funding sources.

Revenue in Q2 2012 declined slightly year over year to $316.9 million primarily due to a year over year decline in wholesale revenue. Second quarter 2012 wholesale revenue of $117.6 million, was sequentially flat as compared to first quarter 2012 wholesale revenue of $117.8 million, and down (11)% year over year despite a 50% increase in wholesale usage over the same period.

Some other notes on Clearwire:

  • Clearwire holds the largest spectrum portfolio in the U.S. but in upper bands.  Its spectrum is an average 163 MHz in the top 100  U.S. markets.
  • Clearwire's network at the end of Q2 2012 covered 134 million POPs, about the same as a year earlier.
  • At the end of Q2 2012, Clearwire was serving 9.6 million wholesale subscribers (mostly Sprint) and 1.3 million retail subscribers.  This compares with 6.4 million wholesale and 1.3 million retail subscribers a year earlier.
  • ARPU for Q2 2012 was $46.12 compared with $47.59 a year earlier.
  • Clearwire's CAPEX in Q2 2012 was $24 million
  • Sequans and Qualcomm are key silicon contributors in the TD-LTE ecosystem.
  • China Mobile and Clearwire have agreed to TD-LTE roaming betweeen U.S. and China.

A Busy Month for Softbank: Acquisition of eAccess (Japan) and Discussions with Sprint

Sprint confirmed published reports that it is in discussion with Softbank of Japan about a possible take-over or major investment.

Various media sources have speculated that a buyout of Sprint could be worth US$12.8 billion.  Softbank may also be looking at acquiring Clearwire.

Sprint is the No.3 mobile operator in the U.S. with 56 million subscribers.

Both Clearwire and Softbank Japan are pursuing TD-LTE for their respective networks.

http://newsroom.sprint.com/article_display.cfm?article_id=2414

The news follows closely on Softbank's decision to undertake another major deal in its home market.


Earlier this month, Softbank Mobile agreed to acquire eAccess in a deal that combines Japan's No.3 and No.4 mobile operators.  The stock-swap was valued at approximately ¥180 billion, or $2.3 billion.

The companies plan to continue to operate both the Softbank and EMOBILE brands following the merger.  Network and spectrum integration will provide key advantages to both brands.

SOFTBANK MOBILE will provide eAccess with access to its 900 MHz network (Band8, operating band specified in 3GPP) and 2.1 GHz network (Band1, operating band specified in 3GPP), which will allow eAccess to provide the voice and data communications service in broader areas.

eAccess will provide SOFTBANK MOBILE with access to its 1.7 GHz (Band3, operating band specified in 3GPP) FDD LTE network for the data communications service, which will allow SOFTBANK MOBILE to use both 2.1 GHz and 1.7 GHz for its FDD LTE service.

SOFTBANK MOBILE and eAccess will integrate their base station sites, enabling both brands to expand service coverage more quickly and to decrease capital expenditures and maintenance costs.  The backbone and backhaul networks will also be integrated.
Softbanks currently has more than 9,000 LTE base stations in operation.  It plans to scale this to 20,000 LTE base stations by March 2013.  At this point, eAccess should have about 10,000 LTE base stations of its own.

Softbank said the deal gives it a key spectrum advantage over Japan's No. mobile operator, KDDI-au.  For iPhone 5 service, Softbank will be able to offer coverage over both the 1.7 GHz and 2.1 GHz bands, whereas au will be limited to its 2.1 GHz spectrum footprint.
