Hybrid WAN boosts agility

Published

on

85% of IT leaders feel that they have a timeframe of just two years to adopt new technologies, or risk falling behind. However many can stay agile should they adopt a hybrid WAN, writes TAJ ELKHAYAT, Regional Vice President, Middle East and Africa at Riverbed Technology.

In the past, most applications were housed on-premises and the WAN was a well-defined and predictable environment. This is no longer the case, as nowadays, the WAN is continually changing and both the applications and architecture that it supports are becoming increasingly challenging to maintain. With more and more applications transitioning to the cloud – public, private or SaaS – the cloud has become an essential element of enterprise architecture as many organisations embark on a digital transformation strategy. Today, 85% of IT leaders feel that they have a timeframe of just two years to adopt new technologies, or risk falling behind.

Consequently, IT now has to manage an increasing number of on-premises and cloud-based applications. The growing number of apps combined with the escalating demand for video and rich-media means that the public Internet is now often used along with MPLS to address enterprises’ rapidly increasing needs for bandwidth. This certainly has cost benefits. However, it can impact IT’s ability to have visibility or understanding of application performance. Changes to the WAN have a negative impact on app performance and businesses must find new approaches to tackle this and optimize app performance and reliability.

As a result, the WAN is evolving toward a hybrid mix that combines the performance of on-premises hardware with the agility and elasticity of cloud based network functions. As enterprises are becoming hybrid, the shape of the network itself is seeing significant changes. The underlying networks are getting more diverse in terms of performance and security.

Controlling the edge of the network

Business now takes place at the edge of the network perimeter – at the branch, at home, from remote locations or on the road. Availability and speed are the biggest priority and keeping business applications running in remote and branch office locations can address this. However, it’s important to note that in the new hybrid WAN, direct Internet access can actually put businesses’ sensitive data at risk from cyber-attacks. Whilst the cloud offers agility and cost-efficiency, the performance is often less than ideal for the end-user and is more difficult for IT to control and optimise. Enterprises can tackle this by looking for solutions which allow them to unify IT management from one central location, such as the data centre or the cloud, all the way to the edge. Regardless of where applications are hosted, IT must be able to ensure optimal performance and secure availability.

Agility and application performance are key WAN requirements

In today’s increasingly digital world, application performance is at the heart of business productivity. Applications can help facilitate business functions, ranging from manufacturing, to processing sales. They also help us communicate and collaborate. However, as we rely on applications more and more, this means that the end-user has high expectations around performance levels.

IT must be able to make these applications available to users and respond to business needs as quickly as possible. Whether this requires setting up a new branch office or making a new SaaS application available to employees, agility is key. IT must be able to deploy sites, rollout applications and handle change management, all whilst ensuring that application performance runs seamlessly.

Tackling application complexity with operational development

Applications are now becoming richer and more complex as the majority become encrypted. Delivered from the data centre, the cloud and the edge, users are accessing them from everywhere. The edge is fast becoming the centre of communication for enterprise and IT must now consider solutions that automate application delivery over the WAN and facilitate intelligence, performance and security requirements as well as abstracting communication resources. This requires automated systems and orchestration which can support these abstractions and align IT with the wider business needs.

Maximise productivity by optimize application performance

Poor application performance can have significant negative impact on a business, affecting not only employee productivity, but also customer satisfaction. Today’s hybrid WAN has introduced new challenges. As bandwidth is now more cost-effective and readily available, the rapid adoption of SaaS and cloud applications means that it can be difficult for IT to keep up with who is using what apps. This in turn leads to poor visibility of end-user experience and an inability to manage infrastructure and application performance.

Encryption can hide application traffic and further obscure the distinction between applications. This means that IT now requires visibility beyond encryption to understand the specific applications accessed by various users. Once this is achieved, they can prioritise and direct application traffic. This can reduce the number of transactions across the WAN for faster application performance and less burden on communication lines.

Harnessing unification and simplification

In order to meet the changing agility requirements of the enterprise, IT will need solutions which will simplify operations across their hybrid network from the data centre or cloud to the LAN or across the hybrid WAN to users across multiple locations. Therefore, to uphold future agility requirements, it will become critical for enterprises to have the ability to abstract and virtualise communication resources between users and data, no matter where they are.

Whilst software-defined WAN (SD-WAN) solutions are being developed to satisfy these requirements, holistic solutions will unify control across networks, the cloud and mobile workers. SD-WAN, when coupled with WAN optimisation, will significantly improve performance and infrastructure efficiencies.

Auto rivals team up for connected car demo

Rivals BMW, Ford and Groupe PSA, maker of Peugeot and Opel cars, have teamed up with the 5G Automotive Association (5GAA), Qualcomm Technologies and Savari for Europe’s first live demonstration of C-V2X direct communication technology operating across vehicles from multiple auto manufacturers.

The live demonstration also featured a live showcase of C-V2X direct communication technology operating between passenger cars, motorcycles, and roadside infrastructure. C-V2X is a global solution for vehicle-to-everything (V2X) communication in support of improved automotive safety, automated driving and traffic efficiency.

The demonstration exhibited the road safety and traffic efficiency benefits of using C-V2X for Vehicle-to-Vehicle (V2V) collision avoidance, as well as Vehicle-to-Infrastructure (V2I) connectivity to traffic signals and Traffic Management Centers (TMC). C-V2X was operated using real-time direct communications over ITS spectrum and demonstrated its ability to work without cellular network coverage, and underscores its commercial readiness for industry deployment as early as 2020. Superior performance and cost-effectiveness compared to other V2X technologies, along with forward-compatibility with 5G, make C-V2X direct communications a preferred solution for C-ITS applications.

Six demonstrations were shown including: Emergency Electronic Brake Light, Intersection Collision Warning, Across Traffic Turn Collision Risk Warning, Slow Vehicle Warning and Stationary Vehicle Warning, Signal Phase and Timing / Signal Violation Warning and Vulnerable Road User (pedestrian) Warning. The vehicles involved included two-wheel e-scooters provided by BMW Group, and automotive passenger vehicles provided by Ford, Groupe PSA, and BMW Group, all of which were equipped with C-V2X direct communication technology using the Qualcomm® 9150 C-V2X chipset solution.  V2X software stack and application software, along with roadside infrastructure, were provided by industry leader, Savari.

C-V2X is globally supported by a broad automotive ecosystem, which includes the fast growing 5GAA organization.  The 5GAA involves over 85 global members comprised of many leading automakers, Tier-1 suppliers, software developers, mobile operators, semiconductor companies, test equipment vendors, telecom suppliers, traffic signal suppliers and road operators.  

Cellular modems will be key to the C-V2X deployment in vehicles to support telematics, eCall, connected infotainment and delivering useful driving/traffic/parking information. As C-V2X direct communication functionality is integrated into the cellular modem, C-V2X solutions are expected to be more cost-efficient and economical over competing technologies, and benefit from accelerated attach rates.  C-V2X direct communication field validations are currently underway in Germany, France, Korea, China, Japan and the U.S.

C-V2X currently stands as the only V2X technology based on globally recognized 3rd Generation Partnership Project (3GPP) specifications, with ongoing evolution designed to offer forward compatibility with 5G.  C-V2X also leverages and reuses the upper layer protocols defined by the automotive industry, including the European Telecommunications Standards Institute (ETSI) organization. C-V2X includes two complementary transmission modes: 

  • Direct communication as shown in this demonstration for V2V and V2I use cases
  • V2N network communication, which leverages mobile operators for connectivity and delivers cloud-based services, including automated crash notification (ACN, as mandated by eCall), hazard warnings, weather conditions, green light optimal speed advisory (GLOSA), parking spot location, and remote tele-operation to support automated driving, to name a few.

“This demonstration builds on the successful C-V2X showcase we organised with our members Audi, Ford and Qualcomm in Washington DC in April, said Christoph Voigt, Chairman of 5GAA.

“We are excited to witness the growing momentum behind this life-saving technology and to see our members working together to deploy C-V2X, and to make it hit the road as soon as possible.”  

“The BMW Group introduced the first C-ITS use cases already in 2013 with the market introduction of the BMW i3. Today most of envisaged C-ITS use-cases are already institutionalized. With the implementation of C-V2X, the BMW Group accomplishes the last set of the puzzle with a practical path to C-ITS showing quick benefits,” said Christoph Grote, Senior Vice President Electronics, BMW Group. 

“With its ability to safely and securely connect vehicles, along with its evolution into 5G, C-V2X is integral to Ford’s vision for future transportation in which all cars and infrastructure talk to each other,” said Thomas Lukaszewicz, Manager Automated Driving, Ford of Europe. “We are very encouraged by preliminary test results in Europe and elsewhere which support our belief that C-V2X direct communications has superior V2X communication capabilities.”

“We’re moving forward with seamless communication between cars and their environment for enhancing road safety, as well as our customers’ safety,” said Carla Gohin, Group PSA’s Vice President for Research and Advanced Engineering. “Following the first European C-V2X direct communications demonstration we hosted with Qualcomm Technologies last March, we’re pleased to work with leading automotive and technology companies today to highlight that C-V2X interoperability is a reality.” 

“This demonstration of interoperability between multiple automakers is not only another milestone achieved towards C-V2X deployment, but also further validates the commercial viability and global compatibility of C-V2X direct communications for connected vehicles,” said Enrico Salvatori, senior vice president & president, Qualcomm Europe and MEA. “We look forward in continuing to work alongside leaders in the automotive industry, like the 5GAA, BMW Group, Ford, Groupe PSA and Savari, to help advance the automotive industry’s shift towards a safer, connected and more autonomous future.” 

“As one of the V2X pioneers, our company is extremely pleased to continue to help enable the next step in the V2X revolution that we helped start back in 2008,” said Ravi Puvvala, CEO of Savari. “For the last year and a half, the Savari team has worked diligently alongside the dedicated C-V2X engineers in the 5GAA partnership. The resulting string of increasingly impressive demonstrations is continuing to convince the world that C-V2X will soon be deployed around the world.”

Win a Poster Heater with Gadget and Takealot.com

This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.

Published

on

Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.

What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.

However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.

As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.

It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.

The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.

To enter the competition follow the steps below:

Competition entry details:

1. Follow @GadgetZA and @Takealot on Twitter. (We will ONLY be accepting entires via Twitter, so please don’t enter through the comments section of this article.)
