Blueprint: 2015 Top Networking Predictions

by Martin Nuss, Vitesse Semiconductor

2015 should be a defining year in the communications industry, thanks in large part to our world’s growing connectedness – between people, and machines, and more and more “things.” Here’s a look at what I expect will dominate the networking industry focus in the coming year.

Ethernet will be everywhere – 2015 will be the year where Ethernet will conquer industrial IoT networks

We have seen it again and again, and it’s about to happen at least twice more: networking protocols that have been long entrenched in specific markets and applications are being replaced by Ethernet.

This first happened for the Enterprise Local Area Network in the late 1990s, and we have seen the same thing happening in Carrier networks starting around 2010, where Ethernet replaced SONET/SDH, PDH, Frame Relay, and ATM. This transition is well underway, and another one just started:  the transition of the many legacy Industrial-IoT protocols like PROFINET, ControlNet, Fieldbus, HART and Ethernet/IP to standards-based Ethernet. Why is this all happening? The answer is simply that the industry has evolved the Ethernet standards and protocols over time to address most, if not all, the of special requirements of the industrial market like high availability, quality-of-service, and network synchronization.

In 2015, we will see the Ethernet standards tackle the last hurdle:  making Ethernet deterministic, so that a packet can be guaranteed to be delivered and accepted by mission-critical devices within a specific time window. This will be accomplished as part of the IEEE 802.1tsn (time sensitive networking) effort, after which Ethernet switches know exactly the time in the network, and can deliver packets out of queues at a certain time or within a certain time. This new Ethernet technology will be relevant not only to factory automation and industrial control systems, but also transportation in general and mission-critical systems like antilock brakes and advanced driver assist and collision avoidance systems in automobiles. The automotive market will thus be the next convert to Ethernet.

By 2020, the number of Ethernet connections in automobiles will exceed all other Ethernet-connected devices in the world

All major automotive companies are driving the replacement of the many legacy and semi-proprietary protocols used within cars by Ethernet to drive economies of scale for the IC supply chain, and to accommodate the ever increasing connectivity and bandwidth challenges in the connected car. It started with infotainment systems and backup cameras being connected by Ethernet, but soon, much more critical systems like diagnostics, advanced driver assist (collision avoidance) systems, and even the main system bus in the car will be Ethernet-networked.

By 2020, more than 120 million cars will be equipped with Ethernet connectivity, with the premium segment connecting up to 35 systems with Ethernet, and in mid-range vehicles, between 8-20 systems. All in all, that translates to somewhere between 500-600 million ports, more than all the Ethernet LAN ports combined today. This is all enabled by new 2-wire Ethernet PHYs developed as part of the IEEE 802.3 100Base-T1 and 1000Base-T1 standards developments, as well as the IEEE 802.1tsn “Deterministic Ethernet” standardization.

In the near-term, all the Software-Defined-Networking (SDN) attention will cut into switch and router sales

Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) have captured the attention and imagination of the networking world, and eventually will revolutionize networks of the future. In the near-term, however, they are putting a damper on switch and router sales as network operators and large enterprises figure out what SDN and NFV mean to them, what the business opportunities are, and how to migrate their networks to a more software- and IT-centric model. For wide-area operators in particular, SDN is a tough value proposition. Although the flexibility of a software-defined network can reduce operational and perhaps even capital costs, most of the equipment in the network is “free” since it is already there, and won't be fully depreciated until years from now. The key to SDN’s success is therefore to figure out how to allow the existing network to participate in the new IT-centric operational model with more centralized control planes and network-wide orchestration. Once that is clear, switch and router sales will pick up again.

Management and network orchestration hold the key to the SDN/NFV network revolution

Although Software-Defined Networking (SDN) and Network Function Virtualization (NFV) are often mentioned in the same context, they are actually different beasts. But what is common to both is an IT-centric view of the network, as opposed to the traditional operational network model. The benefit of the IT-centric model is that network and compute resources can be abstracted from the underlying network and server infrastructure, and “orchestrated” together to deliver services to customers – in minutes and hours as opposed to months.

We predict that the biggest opportunity and revolution will be on this management and orchestration side, and to a lesser degree, on the networking and compute infrastructure side. This will be a dramatic and painful transition, as network operators have to assess skill sets and organizational structures and figure out how to migrate their networks to this new model. Once they do, the revolution can take place.

Security will be the key for Internet of Things (IoT) to succeed

Not a week goes by without a new security breach reported in the press. These threats are not isolated to consumers and credit card and identity thefts, but increasingly are also targeted at Industrial IoT networks. The biggest economic benefits are being realized only when more and more systems are connected to each other and to the cloud, but security becomes a central concern now. No single security scheme can solve all potential vulnerabilities, so it is important to secure applications, networks, and devices. The three As – Authentication, Authorization, and Accounting – apply to all of the above, and are commonplace now for the applications layer, combined with data confidentiality (encryption). But the same principles are enforced less for the network and device/link layer. The link/device layer may be particularly vulnerable since outside of physically secured locations, small cells could be swapped out for rogue devices that can get access to the entire network. Luckily, link layer AAA and encryption technologies like IEEE 802.1AE MACsec are now available even with strong 256-bit AES encryption technologies to secure those last links.

Vitesse’s offering includes advanced Operations and Maintenance (OAM) supporting service provider end-to-end provisioning, monitoring and managing of their Ethernet Virtual Circuits (EVCs).  Vitesse Serval-2, LynX-2 and Jaguar-2 Carrier Ethernet switch engines are the only merchant silicon solutions available today which can support both ITU (Y.1731) and IETF standards (BFD) for MPLS-TP OAM in hardware, enabling line rate performance.

Access equipment based on MPLS-TP can deliver capabilities such as enhanced protection and connection-oriented packet switching, ideal for the ongoing transition from TDM to packet-based

“We see MPLS-TP as a growing market requirement over the next few years – according to our global service provider research, over half of operators have deployed or plan to deploy MPLS-TP in the next two years,” stated Michael Howard, principal analyst for carrier networks and co-founder of Infonetics Research. “MPLS-TP is emerging as a must-have technology for service providers deploying an Ethernet Virtual Circuit-like architecture end-to-end over their network. Vitesse’s ViSAA technology building blocks can enable MEF CE 2.0 feature-full service delivery over Ethernet and MPLS-TP networks.”

“The potential capex and opex advantages of using an EVC-like architecture end-to-end over carrier networks are largely untapped today,” said Craig Pasek, software product marketing manager at Vitesse. “MPLS-TP gives Ethernet service delivery robustness, greater scale, stronger layering and protection. Turnkey solutions like Vitesse’s that readily enable MEF CE 2.0, feature-rich service delivery over Ethernet and MPLS-TP networks will be essential for carriers to fully leverage those capex/opex."

Vitesse Extends its 10GE PHY Portfolio

Vitesse Semiconductor introduced the latest generation of its widely adopted 10 Gigabit Ethernet (GE) PHY portfolio, the VSC8489 physical layer transceiver family.

The new devices offer a low cost, flexible LAN/WAN solution with multiple interface options for KR backplane and SR/LR/ER/ZR/220MMF optical module applications. The VSC8489 family also has the industry’s smallest footprint in its feature class, consuming 22% less area than the competition. Target applications include enterprise data centers supporting cloud services.

Vitesse said its new VSC8489 family includes two products with VeriTime, the industry’s de facto highest accuracy IEEE 1588v2 timing synchronization technology, as well as one without VeriTime for cost-sensitive applications that are not timing-critical. The VSC8489 family allows customers to choose the right 10GE PHY for their needs now, with a seamless and pin-compatible upgrade path to advanced timing and security features if, or when, they are required in the future.

“Demand for greater bandwidth and more feature-rich solutions at the physical layer is evident everywhere, from the Enterprise to service providers, as 10G technologies become increasingly more cost effective,” said Richard Interrante, product marketing director at Vitesse. “The VSC8489 family gives OEMs an efficient way to upgrade networks transitioning to cloud and other virtualized environments.”

The VSC8489 family is in production now. Product details are online.

Blueprint: Impending ITU G.8273.2 to Simplify LTE Planning

By Martin Nuss, Vitesse Semiconductor

Fourth-generation wireless services based on long-term evolution (LTE) have new timing and synchronization requirements that will drive new capabilities in the network elements underlying a call or data session. For certain types of LTE networks, there is a maximum time error limit between adjacent cellsites of no more than 500 nanoseconds.

To enable network operators to meet the time error requirement in a predictable fashion, the International Telecommunications Union is set to ratify the ITU-T G.8273.2 standard for stringent time error limits for network elements. By using equipment meeting this standard, network operator will be able to design networks that will predictably comply with the 500-nanosecond maximum time error between cellsites.

In this article, we look at the factors driving timing and synchronization requirements in LTE and LTE-Advanced networks and how the new G.8273.2 standard will help network operators in meeting those requirements.

Types of Synchronization

Telecom networks rely on two basic types of synchronization. These include:
Frequency synchronization
Time-of-day synchronization, which includes phase synchronization

Different types of LTE require different types of synchronization. Frequency division duplexed LTE (FDD-LTE), the technology that was used in some of the earliest LTE deployments and continues to be deployed today, uses paired spectrum. One spectrum band is used for upstream traffic and the other is used for downstream traffic. Frequency synchronization is important for this type of LTE, but time-of-day synchronization isn’t required.

Time-division duplexed LTE (TD-LTE) does not require paired spectrum, but instead separates upstream and downstream traffic by timeslot. This saves on spectrum licensing costs but also allows to more flexible allocate bandwidth flexibly between upstream and downstream direction, which could be valuable for video.  Time-of-day synchronization is critical for this type of LTE. Recently TD-LTE deployments have become more commonplace than they were initially and the technology is expected to be widely deployed.

LTE-Advanced (LTE-A) is an upgrade to either TD-LTE or FDD-LTE that delivers greater bandwidth. It works by pooling multiple frequency bands, and by enabling multiple base stations to simultaneously send data to a handset. Accordingly adjacent base stations or small cells have to be aligned with one another – a requirement that drives the need for time-of-day synchronization. A few carriers, such as SK Telecom, Optus, and Unitel, have already made LTE-A deployments and those numbers are expected to grow quickly moving forward.

Traditionally wireless networks have relied on global positioning system (GPS) equipment installed at cell towers to provide synchronization. GPS can provide both frequency synchronization and time-of-day synchronization. But that approach will be impractical as networks rely more and more heavily on femtocells and picocells to increase both network coverage (for example indoors) and capacity. These devices may not be mounted high enough to have a line of sight to GPS satellites – and even if they could, GPS capability would make these devices too costly.  There is also increasing concern about the susceptibility of GPS to jamming and spoofing, and countries outside of the US are reluctant to exclusively rely on the US-operated GPS satellite system for their timing needs.

IEEE 1588

A more cost-effective alternative to GPS is to deploy equipment meeting timing and synchronization standards created by the Institute of Electrical and Electronics Engineers (IEEE).

The IEEE 1588 standards define a synchronization protocol known as precision time protocol (PTP) that originally was created for the test and automation industry. IEEE 1588 uses sync packets that are time stamped by a master clock and which traverse the network until they get to an ordinary clock, which uses the time stamps to produce a physical clock signal.

The 2008 version of the 1588 standard, also known as 1588v2, defines how PTP can be used to support frequency and time-of-day synchronization. For frequency delivery this can be a unidirectional flow. For time-of-day synchronization, a two-way mechanism is required.

Equipment developers must look outside the 1588 standards for details of how synchronization should be implemented to meet the needs of specific industries. The ITU is responsible for creating those specifications for the telecom industry.

How the telecom industry should implement frequency synchronization is described in the ITU-T G.826x series of standards, which were ratified previously. The ITU-T G.8273.2 standard for time-of-day synchronization was developed later and is expected to be ratified next month (March 2014).
Included in ITU-T G.8273.2 are stringent requirements for time error. This is an important aspect of the standard because wireless networks can’t tolerate time error greater than 500 nanoseconds between adjacent cellsites.

ITU-T G.8273.2 specifies standards for two different classes of equipment. These include:
Class A- maximum time error of 50 ns
Class B- maximum time error of 20 ns

Both constant and dynamic time errors will contribute to the total time error of each network element, with both adding linearly after applying a 0.1Hz low-pass filter. Network operators that use equipment complying with the G.8273.2 standard for all of the elements underlying a network connection between two cell sites can simply add the maximum time error of all of the elements to determine if the connection will have an acceptable level of time error. Previously, network operators had no way of determining time error until after equipment was deployed in the network, and the operators need predictability in their network planning.

Conforming to the new standard will be especially important as network operators rely more heavily on heterogeneous networks, also known as HetNets, which rely on a mixture of fiber and microwave devices, including small cells and femtocells. Equipment underlying HetNets is likely to come from multiple vendors, complicating the process of devising a solution in the event that the path between adjacent cell sites has an unacceptable time error level.

What Network Operators Should Do Now

Some equipment manufacturers already have begun shipping equipment capable of supporting ITU-T G.8273.2, as G.8273.2-compliant components are already available. As network operators make equipment decisions for the HetNets they are just beginning to deploy, they should take care to look for G.8273.2-compliant products.

As for equipment already deployed in wireless networks, over 1 million base stations currently support 1588 for frequency synchronization and can be upgraded to support time-of-day synchronization with a software or firmware upgrade.

Some previously deployed switches and routers may support 1588, while others may not. While 1588 may be supported by most switches and routers deployed within the last few years, it is unlikely that they meet the new ITU profiles for Time and Phase delivery.  IEEE1588 Boundary or Transparent Clocks with distributed time stamping directly at the PHY level will be required to meet these new profiles, and only few routers and switches have this capability today.  Depending where in the network a switch or router is installed, network operators may be able to continue to use GPS to provide synchronization, gradually upgrading routers by using 1588-compliant line cards for all new line card installations and swapping out non-compliant line cards where appropriate.

Wireless network operators should check with small cell, femtocell and switch and router vendors about support for 1588v2 and G.8273.2 if they haven’t already.
