●   Edge networking continues to gain more intelligence and capacity to support evolving network demands and superior network experiences. Increasingly, global service providers are making networking investments and architectural transformations to bolster the capabilities at the network edge. Based on our analysis, 33 percent of global service provider network capacity will be within a metro network by 2022 (up from 27 percent in 2017). Comparatively, 24 percent of global service provider network capacity will be in regional backbones by 2022 (down from 25 percent in 2017) and 43 percent of global service provider network capacity will be in cross-country backbones by 2022 (down from 48 percent in 2017).
Users expect their online experience to be always available and always secure—and their personal and business assets to be safe. The last several years have been easily the most eventful period from a security threat perspective, with many serious data breaches that have been discussed widely in the media. Given the scope of the monetary and brand damage associated with data breaches, cybersecurity is treated as a business risk rather than merely an IT issue. Advances in technology is the main driver for economic growth but has also led to a higher incidence of cyberattacks. The leading trends such as ecommerce, mobile payments, cloud computing, Big Data and analytics, IoT, AI, machine learning, and social media, all increase cyber risk for users and businesses. Compounding the problem, the nature of the threats is becoming more diverse. The list includes Distributed Denial-of-Service (DDoS), ransomware, Advanced Persistent Threats (APTs), viruses, worms, malware, spyware, botnets, spam, spoofing, phishing, hacktivism and potential state-sanctioned cyberwarfare.

Websites consisting mostly of affiliate links have previously held a negative reputation for underdelivering quality content. In 2005 there were active changes made by Google, where certain websites were labeled as "thin affiliates".[34] Such websites were either removed from Google's index or were relocated within the results page (i.e., moved from the top-most results to a lower position). To avoid this categorization, affiliate marketer webmasters must create quality content on their websites that distinguishes their work from the work of spammers or banner farms, which only contain links leading to merchant sites.


Overall IP traffic is expected to grow to 396 EB per month by 2022, up from 122 EB per month in 2017, a CAGR of 26 percent (Figure 1). This growth represents a slight increase in expectations over last year’s forecast, which projected a CAGR of 24 percent from 2016 to 2021, driven by an increase in the growing share of mobile traffic as a percentage of the total IP traffic.

Anecdotal evidence supports the idea that overall use increases when speed increases, although there is often a delay between the increase in speed and the increased use, which can range from a few months to several years. The reverse can also be true with the burstiness associated with the adoption of tablets and smartphones, where there is a delay in experiencing the speeds that the devices can support. The Cisco VNI Forecast relates application bit rates to the average speeds in each country. Many of the trends in the resulting traffic forecast can be seen in the speed forecast, such as the high growth rates for developing countries and regions relative to more developed areas (Table 6).
Also, of note in the recent forecast is the growing number of countries whose fixed traffic growth rivals that of their mobile traffic growth. United States is the outlier, with a fixed growth of 26 percent in 2017 and a mobile growth of 23 percent over the same time period. Japan, Korea, Canada, Germany and Sweden, all have fixed growth that is only slightly lower than their mobile growth. The majority of countries still have significantly higher growth rates for mobile than for fixed.
The rapid growth of mobile data traffic has been widely recognized and reported. The trend toward mobility carries over into the realm of fixed networks as well, in that an increasing portion of traffic will originate from portable or mobile devices. Figure 21 shows the growth in Wi-Fi and mobile traffic in relation to traffic from wired devices. By 2022, wired networks will account for 29 percent of IP traffic, and Wi-Fi and mobile networks will account for 71 percent of IP traffic. In 2017, wired networks accounted for 48 percent of IP traffic; Wi-Fi accounted for 43 percent; and mobile or cellular networks accounted for 9 percent of total global IP traffic.
Work[9] involving supervised machine learning to classify network traffic. Data are hand-classified (based upon flow content) to one of a number of categories. A combination of data set (hand-assigned) category and descriptions of the classified flows (such as flow length, port numbers, time between consecutive flows) are used to train the classifier. To give a better insight of the technique itself, initial assumptions are made as well as applying two other techniques in reality. One is to improve the quality and separation of the input of information leading to an increase in accuracy of the Naive Bayes classifier technique.
In addition to the Internet Health Report, several major Internet backbone providers have Web sites that post hourly or more frequent statistics on how fast data is travelling on their backbone lines and the percentage of data packets that are being lost. Our table summarizes these sites, the information they provide, and how often they are updated.
From a traffic perspective, we expect that on average a household that is still on linear TV will generate much less traffic than a household that has “cut the cord” and is relying on Internet video (Figure 16). A cord-cutting household generated 141 GB per month in 2017, compared to 82 GB per month for an average household. This difference occurs because linear television generates much less traffic (one stream of video shared across numerous linear-TV households) than Internet video, which is unicast to each Internet video device.
Critical enablers of Hotspot 2.0 adoption are higher speed Wi-Fi gateways and the adoption of the IEEE 802.11ac and the latest 802.11ax standards. Globally, the prevalence of IEEE 802.11ac, the latest Wi-Fi standard, will gain momentum from 2017 through 2022. By 2022, 86.9 percent of all Small Office Home Office (SOHO) Wi-Fi routers will be equipped with 802.11ac. IEEE 802.11n, which was ratified in 2007, provides a range of speeds that allow users to view medium-resolution video streaming because of the higher throughput. IEEE 802.11ac, with very high theoretical speeds, is considered a true wired complement and can enable higher definition video streaming and services with use cases that require higher data rates. The latest 802.11ax also called the High-Efficiency Wireless (HEW), has the goal of improving the average throughput per user by a factor of at least four times in dense user environments. It will enable dense IoT deployments. By 2022, 9.5% of total SOHO routers will be equipped with 802.11ax (Figure 20).
The phrase, "Affiliates are an extended sales force for your business", which is often used to explain affiliate marketing, is not completely accurate. The primary difference between the two is that affiliate marketers provide little if any influence on a possible prospect in the conversion process once that prospect is directed to the advertiser's website. The sales team of the advertiser, however, does have the control and influence up to the point where the prospect either a) signs the contract, or b) completes the purchase.
Affiliates were among the earliest adopters of pay per click advertising when the first pay-per-click search engines emerged during the end of the 1990s. Later in 2000 Google launched its pay per click service, Google AdWords, which is responsible for the widespread use and acceptance of pay per click as an advertising channel. An increasing number of merchants engaged in pay per click advertising, either directly or via a search marketing agency, and realized that this space was already occupied by their affiliates. Although this situation alone created advertising channel conflicts and debates between advertisers and affiliates, the largest issue concerned affiliates bidding on advertisers names, brands, and trademarks.[39] Several advertisers began to adjust their affiliate program terms to prohibit their affiliates from bidding on those type of keywords. Some advertisers, however, did and still do embrace this behavior, going so far as to allow, or even encourage, affiliates to bid on any term, including the advertiser's trademarks.

Content providers are also moving to increase the IPv6 enablement of their sites and services. According to Cisco® IPv6 labs, by 2022 the content available over IPv6 will be about 51 percent. There can be, however, variation depending on the popularity of websites across regions and countries. In addition, specific country initiatives and content-provider deployments have positively affected local IPv6 content reachability.
The Cisco Visual Networking Index Forecast methodology has been developed based on a combination of analyst projections, in-house estimates and forecasts, and direct data collection. The analyst projections for broadband connections, video subscribers, mobile connections, and Internet application adoption come from SNL Kagan, Ovum, IDC, Gartner, Ookla Speedtest.net, Strategy Analytics, Dell’Oro Group, Synergy, comScore, Nielsen, Maravedis, ACG Research, ABI Research, Media Partners Asia, IHS, International Telecommunications Union (ITU), CTIA, UN, telecommunications regulators, and others. Upon this foundation are layered Cisco’s own estimates for application adoption, minutes of use, and kilobytes per minute. The adoption, usage, and bit-rate assumptions are tied to fundamental enablers such as broadband speed and computing speed. All usage and traffic results are then validated using data shared with Cisco from service providers. Figure 28 shows the forecast methodology.
Smartphones will grow the second fastest, at a 9 percent CAGR (increasing by a factor of 1.6). Connected TVs (which include flat-panel TVs, set-top boxes, digital media adapters [DMAs], Blu-ray disc players, and gaming consoles) will grow next fastest at 7 percent CAGR, to 3.2 billion by 2022. PCs will continue to decline (a 2.5 percent decline) over the forecast period. However, there will more PCs than tablets throughout the forecast period and by the end of 2022 (1.2 billion PCs vs. 790 million tablets).
Websites and services based on Web 2.0 concepts—blogging and interactive online communities, for example—have impacted the affiliate marketing world as well. These platforms allow improved communication between merchants and affiliates. Web 2.0 platforms have also opened affiliate marketing channels to personal bloggers, writers, and independent website owners. Contextual ads allow publishers with lower levels of web traffic to place affiliate ads on websites.[citation needed]
