Cisco Executive Chairman signs R&D MOU with Israel



John Chambers, Cisco's chief executive, company world's largest networks, has signed a protocol agreement on Sunday in the advancement of digitization in Israel during a meeting with Prime Minister Benjamin Netanyahu.

Three years earlier, Chambers predicted that Israel would be the first country to be scanned from beginning to end, and Sunday MOU seemed to define a roadmap for how this could happen.

The MOU scored ten different possible areas for cooperation between the company and the Israeli, such as digital education, digital health, human capital, innovation and government research centers.

Cisco technology could be used to create the fastest Internet infrastructure and make it easier to connect devices to the "Internet of things", the everyday devices network by sensors and modems.

In health, for example, the introduction of portable devices could be helpful for researchers guzzling data, and help doctors end when patients get sick.

The government also seeks modes more effectively itself, creating a common data system in the cloud that would make it easier for departments to communicate with each other and build a plan to exploit the power of creation of Israeli companies in government. The Office of the Chief Scientist is developing a similar initiative.

On Monday, the center of Jerusalem R & D will host Cisco cameras at an event in the future of television, called "The future starts now."

It is intended to showcase new innovations in the field of television and video, including cloud storage for video, customizable televisions, virtual reality, and new security features.

Australian fixed broadband speeds to average 44.3Mbps by 2020

Cisco released its report Visual Networking Index (VNI) for Australia, showing that if the line speed increase fixed Internet 2.4 times over the next five years, Australia will step behind the rest of the world.

With the forecast report traffic Australia, Kevin Bloch, chief technology officer of Cisco Australia and New Zealand, he referred to the forecast traffic levels Cisco Internet, use of the device, and a breakdown of technology for the five-year period between 2015 and 2020.

According to Cisco, the average speed of a fixed broadband connections including national broadband network (NBN), is expected to leave 18.4Mbps to 44.3Mbps in 2015 in 2020.

For fixed broadband by 2020, 81 percent of the connections will be faster than the speed of 5 Mbps; 53 percent will be faster than 10 Mbps; 17.7 percent will be faster than 25 Mbps; and 16 percent will be faster than 50 Mbps.

Average speed Wi-Fi will also increase by 2.6 times during the five-year period, from 9.1Mbps to 23Mbps, while average mobile connection speeds will double to 16 Mbps in 2020.

Bloch said that Australia was "too far" in speed, but said it is not so much the speed that is used for connectivity.

"The worst thing we can be as a country is complacent. The fact that we either AU $ 41 or AU $ 29 million in infrastructure nationwide broadband [Network], to me that's just the beginning, because only we're shooting faster electrons. What to do with these electrons? This is much more important, "admits the director of technology.

"We ensure that the physical copper optics, HFC [hybrid fiber-coaxial] infrastructure, and this is a good thing for us, but I spend much of my time thinking about what that means?

"The message we try to convey the Australian company is that we are in a race. And this is not a race between two Australian companies, is a race between Australia and the rest of the world. And I really learned to kick your ass here, and we to go all. '

The Australian IP traffic will grow three times between 2015 and 2020 at an annual growth rate (CAGR) of 21 percent, reaching 1.9 exabytes per month and 62 petabytes per day, with an annual supply of 22 May exabytes. IP traffic will average 6Tbps 2020, while "rush hour" or demand peaks reach 32Tbps.

The total Internet traffic will grow from 606 petabytes per month in 2020 to 1.7 exabytes, or 55 petabytes per day, compared to 20 petabytes per day in 2015. Internet traffic busy hours grow at a CAGR of 34 percent, reaching 28Tbps, while Internet traffic will average 5Tbps.

The disparity between peak and average data usage is a concern for telecom providers, Bloch said; Advanced divergence of 34.1 percent and 22.4 percent CAGR for the average CAGR will lead to pressure on the networks.

"This is a big problem for telephone companies: average time served and the time difference of about 1.5 is growing rapidly again half - 34 percent CAGR of 22 percent CAGR This is a big problem, because how you build for peak ..? "he said.

"For telcos, which is only getting worse ... we need more content, although technically we have to use this intelligent content, which is what content distribution networks are."

mobile data traffic will increase fivefold between 2015 and 2020 at a CAGR of 40 percent; It rose 6.3 percent of total Internet traffic in 2015, but will make 12.3 percent in 2020. It will reach 204 petabytes per month in 2020, up to 38 petabytes in 2015.

In 2020, Cisco predicted that the average Internet user to generate 60 GB of Internet traffic per month, an increase of 139 percent, and the average household to go through 149.3GB per month, up 146 percent. means fiber to node / basement / local distribution / Point (FTTx) of households 240.7GB generate Internet traffic per month, against 143.1GB in 2015, while the average mobile connection generates 4,777MB mobile data traffic per month, almost 300 percent of 1,199MB reported in 2015.

There will be a total of 21 million Internet users in Australia in 2020, Cisco, representing 81 percent of the total population, compared with 18 million and 74 percent of the population in 2015.

According to Cisco, Australians are "addicted" to video streaming 2020, video traffic to grow three times in 2020 at a CAGR of 27 percent. 1.4 exabytes per month will be reached in 2020 to 418 petabytes per month in 2015, with a total Internet video traffic to make up 82 percent of all Internet traffic in 2020, compared to 69 percent in 2015.

Netflix is ​​having a "significant impact" on the use of rush hour over the Internet, such as smart phones with capabilities increasingly being released, Bloch said.

Internet traffic game, meanwhile, will jump nine times during the same period, at a CAGR of 55 percent. It will increase from 418 petabytes per month to 1.4 exabytes per month, and will make 7 percent of the public Internet traffic in 2020. In 2015, rose 2 percent of Internet traffic consumers.

Cisco also predicts there will be 237 million networked devices in 2020, against 130.4 million in 2015, with 34 percent of these to be connected mobile. Of all networked devices, 59 percent will be (M2M) -Washer machine; 14 percent will be connected TVs; 11 percent will be smartphones; 8 percent will be PC; and 3 percent will tablets.

M2M modules use an average of 0.645GB per month, while smartphones use 11.8GB per month, tablets have an average of 24.7GB per month PCS use 48.7GB per month, and connected TVs using 4K 4.6GB per month.

This growth of Internet devices objects (IOT) and data usage, Bloch refers to backpacks RFID bees CSIRO to talk about what he calls "the IO Lite" - inexpensive devices long battery life that they need to run the IO.

"I'm on the record to say that telecom costs for connecting to the" things "in 10 years will be zero," he added.

"The money is in your applications and data."

Bloch also said that Australia is "really behind" in science, technology, engineering and mathematics (STEM), being in 13th place worldwide. He said the two keywords to STEM are the quality and scale, with a high quality program that will extend across the country. He also said another letter should be added to the acronym.

"It should not be STEM, should be STEMC" says Bloch.

"C is creativity. Because if you look at the computer and humans, humans are very different today what computers can do.

"This is what we think, how to use computers creative technology are far from that.".

The publication of statistics Australia following the publication of the 11th edition of the Cisco Visual Networking Index: Global IP traffic update scheduled two weeks ago. The general report predicts that nearly half of all Internet-connected devices will be objects (IO) 2020 devices.

M2M connections will increase from 4.9 million in 2015 to 12,200,000,000 in 2020, Cisco said, with 46 percent of all connected devices consist of M2M connections.

"A growing number of M2M applications such as smart metering, video surveillance, health monitoring, transport, packaging and asset tracking, contribute significantly to the growth of devices and connections," Cisco said.

The segment of the e-health will experience the highest growth of M2M, Cisco said, from 144 million in 2015 to 729,000,000 in five years. The consumption of domestic industry has most M2M connections, however, with 5.8 million planned for 2020.

Cisco also expects that by 2020 there will be 1 billion new Internet users; global IP traffic will reach 2.3 zettabytes per year; IP video to make up 82 percent of all IP traffic; DDoS attacks will increase to 17 million; VR traffic will increase 61 times; and video conferencing will grow to 248 million users.

Latest Cisco-IBM Deal Brings Watson to the Edge

“We’re trying to reduce the unnecessary transmission of data to the cloud.”

legendary IBM Watson system is well known as a platform that gathers archived data analysis to give an answer that might insoluble problems or questions. A new initiative between Cisco and the IO Watson, however, is likely to lead to a real-time view of any and all terminals.

the collaboration of IBM Cisco is designed to enable organizations in remote areas harness the combined power of analysis capabilities edge the IO Watson and Cisco to understand more deeply and act on critical data on the network edge.

Cisco, through their offers and initiatives supporting the "fog of calculation" is a promoter of the implementation of intelligence at the edge, or anywhere else along the spectrum of connections between devices and centralized servers. "We Cisco combines advanced capabilities with Watson so that we can make intelligent decisions on the edge of the network, the data is valuable," says Mike Flannagan, vice president of Cisco data and analysis.

Cisco provides the "ability to perform advanced analysis of the data flow, and data direction - look aggregates and summaries, such as time series, either one minute, five minutes or an hour on average," he says Flannagan. with this partnership, "Watson offer the opportunity to distribute a small piece of code on its edge, to tell our software data is interesting for them."

The ability to move more analytical processing on board is critical, especially for a real-time based on the IO and other distributed data. But for companies that do not have easy access to bandwidth connectivity, these capabilities are sometimes out of reach or take too long. intend to Cisco and IBM to provide such operational capacity on the edge of the computer, such as oil rigs, factories, transport companies and mines, where time is of the essence, but the bandwidth is often insufficient networks.

For example, workers in remote environments now be able to better monitor the health and behavior of critical machinery and plan more accurately for upgrades and maintenance of the necessary equipment. For example, illustrates Flannagan, "A machine operator may need to take readings for things like vibration, temperature and pressure. If there is a problem that will cause a security problem, I have to find that now, not three days from now ".

In addition, it may be too costly and need to be constantly moving all data generated in a central location for analysis. "You may have to make decisions at the point or close to the point of production," says Flannagan. "You have to decide how and what to do with it."

In general, companies using IBM Watson "have sent all the raw data to the cloud," he says. . Switches routers, bandwidth, cloud capacity - - "Then Watson would have to decide once was there as was a large number of irrelevant data to the cloud, with all necessary infrastructure to do so is sent then throw more if in the end, has not since been relevant to the problem you are trying to solve. We try to reduce unnecessary transmission of data to the cloud. "

The solution is marketed and sold as a whole and include cognitive IO Platform Watson and a real vision of time with IBM analytics continuous Cisco. This will allow real-time analysis to be performed on the edge and data collection for long-term analysis in the cloud.
