PIPE Deploys Infinera's DTN-X for Super-Channel Pacific Capacity


Australia-based PIPE Networks will deploy Infinera's new DTN-X platform with FlexCoherent super-channels on its PPC-1 submarine cable, a 6,900 km undersea system linking Sydney to Guam.

The DTN-X platform significantly increases capacity on PPC-1, delivering in excess of 3 Tbps. It will also allow PIPE to deploy Infinera’s 100 Gbps coherent wavelengths using high capacity super-channel transmission for the first time in the Asia-Pacific region.

This marks the first deployment of optical super-channels in the Asia-Pacific region.

In addition to the submarine deployment, the Infinera DTN-X platform was also selected for the company’s terrestrial network delivering 500 Gbps FlexCoherent super-channels to multiple, strategic data centers located in Sydney. Infinera's DTN-X supports 8 Terabits per second (Tbps) on a single fiber, which will significantly increase the capacity, scalability and resiliency of PIPE’s extensive metro fiber network in Sydney.

Huawei Outlines its Cyber Security Perspectives

"All stakeholders – governments and industry alike – need to recognize that cyber security is a shared global problem requiring risk-based approaches, best practices and international cooperation," according to a new published whitepaper by Huawei entitled "Cyber Security Perspectives: 21st century Technology and Security – a Difficult Marriage."

John Suffolk, the company's Global Security Officer, confronts the risks in cyber security and espionage should network devices or network infrastructure be compromised in any way. Possible attacks could range from "back doors" to complete remote "kill switches" embedded deep within complex equipment. The range of adversaries extends from individual bad actors to corporate spys, organized crime syndicates, terrorist groups and potentially even other governments. He says Huawei would welcome a coordinated international approach to principles of data protection and cyber security.

 For its part, Huawei has adopted an industry best practices approach to go the extra mile in cyber security assurance. Suffolk writes that Huawei "does not, and would not, support, condone or conduct activities intended to acquire sensitive information related to any country, company or individual, nor do we knowingly allow our technology to be used for illegal purposes."

The 24-page paper is posted online.

Exact Ventures Tracks 40% Growth in IMS


The IP multimedia subsystem (IMS) Core market grew nearly 40 percent in the second quarter of this year compared to the same quarter last year, according to a new report from Exact Ventures.

"The total SBC market continues to be boosted by the enterprise SBC category (E-SBC), which continues to be fueled by strong adoption of hosted unified communications and SIP trunking services" said Greg Collins, Founder and Principal Analyst at Exact Ventures.

Some highlights:

  • Wireline deployments in China boosted the IMS market in the second quarter, but those deployments were not strong enough for the market to increase sequentially over the first quarter of this year, which benefited from exceptionally strong voice-over-LTE (VoLTE) deployments in North America.  
  • Huawei led the IMS Core market in the second quarter, followed by Nokia Siemens, Ericsson, and Mavenir, respectively.
  • The total NGN voice and IMS Core market grew only slightly quarter-over-quarter as seasonal strength in the wireless voice core market was barely able to offset sequential weakness in the legacy wireline NGN and IMS Core markets.
  • The service provider session border controller (SP-SBC) market has not been immune to weakness in wireline spending as it was essentially flat both sequentially and year-over-year.

Harnessing Next-Generation Network Timing and LTE

By Martin Nuss, Ph.D., Vice President, Technology and Strategy and Chief Technology Officer, Vitesse

LTE has been rapidly moving towards a packet based backhaul network, while still trying to cope with a dated and inadequate timing model based on TDM.  Timing is necessary for both 3G and 4G deployments. Today, timing is typically delivered by either a SONET/SDH-based T1/E1 line or from GPS satellites.  SONET/SDH is not only expensive, but also inadequate for next-generation wireless networks, since it can only deliver frequency synchronization, but not the time-of-day (ToD) synchronization that is mandatory for TD-LTE and LTE-Advanced (LTE-A) – the “true 4G.”

In many cases, operators use GPS satellites, rather than T1/E1, to provide both phase and frequency synchronization. However, GPS is prone to jamming and faces reception issues for small cell deployments inside a building or in urban corridors, due to the lack of direct GPS satellite visibility. With the advent of LTE-A, with support for multi-band operation, wide use of Multiple-Input/Multiple-Output (MIMO) antenna systems, and increased use of micro and picocells to expand capacity and coverage, the GPS issues become intractable for many operators. For example, many picocell and microcell base stations will be deployed in locations such as lampposts and at the sides of buildings. They are positioned in urban corridors where tall buildings likely will block access to multiple GPS satellites, which would preclude meeting the LTE-A timing specifications.  The optimal solution is to deliver timing through the network, but this has challenges.

Synchronous Ethernet (SyncE) offers a direct replacement for TDM-derived timing as the backhaul network converts to all-Ethernet protocols. However SyncE, like T1/E1-based TDM timing, can support only frequency synchronization, not the newly required time-of-day synchronization. The good news is that the IEEE and the ITU have worked on standardizing a packet-based timing for both frequency and ToD delivery in telecom networks – IEEE 1588v2 Precision Timing Protocol, or PTP.  IEEE 1588v2 or “1588v2” for short has now gained widespread acceptance as the de facto packet based timing protocol for mobile operators.  Market analysts predict that by 2015, Synchronous Ethernet could be used in 30 percent of timing solutions, greater than T1/E1 or GPS deployments. However, in the same timeframe, 1588v2 is expected to grow to over 50 percent of all deployments.

IEEE1588v2: Better Timing Through Time Stamp Collection

Targeted at packet-based backhaul networks, IEEE 1588v2 carries time of day information (also known as timestamps) directly within the data packets.  The packets carrying the timestamps flow along with the rest of the data traffic in the network from networking equipment that generates the timestamps (also known as primary reference clock) all the way to base station equipment where these timestamps are used to recover the original time using IEEE 1588v2. The difference between primary reference clock and recovered clock (i.e. the synchronization error) needs to be within the accuracy requirement shown in Figure 2.  This synchronization error is cumulative across every node in the network in the path between the network node generating the master clock and the base station. Meanwhile, the challenge of migration from FD-LTE to TD-LTE/LTE-A, makes the synchronization error limits even more challenging.

Providing an IEEE 1558v2 implementation with timing errors below the network requirements is paramount to a successful deployment of this technology.   The primary source of the IEEE 1588v2 synchronization error comes from the packet delay variations (PDV) that are inherent in any packet network. The key to meeting the accuracy requirements is an IEEE 1588v2 compliant solution that can compensate for the PDV in the most cost effective way.  The IEEE 1588v2 standard specifies multiple clock types.  Besides ordinary clocks at the beginning and the end of the timing chain, boundary clocks (BC) and transparent clocks (TC) are defined for network elements in between.

In general, a BC node is more complex and costly to implement than a TC node. A node that implements BC regenerates the timing based on the timestamps that it receives and a node that implements TC simply forwards the incoming timestamps after correcting for any error it may introduce. So a TC node requires only accurate time stamping and time stamp correction mechanism, while a BC node requires timestamping, time stamp correction, a reliable PDV filtering algorithm, and a IEEE 1588v2-aware timing complex that can be synchronized to the network.

The only way to meet LTE-A accuracy requirements for both BC and TC is with a well-architected time stamping architecture.  As shown by silicon vendors, such time stamping and correction mechanism can be incorporated into port-level PHY silicon that can be universally used by the equipment vendors in the datapath without any other changes to the system.  In fact, such a port-based PHY solution is completely sufficient to implement a highly accurate TC node, while any BC node also greatly benefits from port-level accurate time stamping.  Under the bottom line, the most cost effective way to upgrading the network for LTE-A and future small-cell networks is to deploy distributed TC’s everywhere, augmented with BC’s only where necessary to segment timing domains. The use of TC’s can increase timing accuracy to the nanosecond range, as shown by Vitesse in a recent submission to the ITU-T standards committee.  Silicon advances available today will insure that such solutions will carry only a nominal premium over non-IEEE 1588v2 aware systems designed for 3G networks today.

Careful TC planning can allow for picocell synchronization in an outdoor environment, and synchronization down to the femtocell in large indoor multi-floor installations.  In the former case, TCs can even be carried over microwave and millimeter-wave links and still meeting TD-LTE and LTE-A specifications while eliminating the requirement for GPS signals or fiber links at the small cell.  In an indoor environment, the access network itself can generate IEEE1588v2 timing, or a GPS antenna on the roof of the building can generate time packets for synchronization of services inside the building, using IEEE 1588v2 to distribute timing within the building.

Upgrading Via a Painless Path

IEEE 1588v2 promises a simple, low-cost option for packet network timing upgrades and an ideal alternative and backup to GPS for TD-LTE and LTE-A networks. In many instances, full IEEE 1588v2 awareness is only needed right at the base station or cell site where timing needs to be provided to the cell.  Within the many hops in the network along the way, Transparent Clocks provide the most cost effective way to upgrade the network to LTE and LTE-Advanced simply by replacing port-level PHYs with new devices such as the ones from Vitesse, that can implement a nanosecond-accurate and highly stable time-of-day forwarding architecture, while fully compensating for transit time and PDV.
