Is Your Network Killing Real-Time Apps?

In the current enterprise environment, there are several applications that businesses simply cannot operate without. These include communication platforms and other tools that enable the streamlined and continual collaboration among employees and customers. However, many of these real-time apps are being killed by network issues.

It’s no secret that so many of today’s “must have” applications require more network support than others. When this support is not in place, it can be detrimental to the successful use of the app, the satisfaction of the employee and the success of the interaction. Issues like adequate capacity, latency and jitter kill real-time apps. Incognito Software CEO Stephane Bourque noted that there can be numerous performance problems when the proper bandwidth support isn’t in place.

“Slower access speeds, pixelation on services, more calls to the help center, [and] poorer [wireless] Internet access,” Bourque said. “[Administrators] need to be able to point the finger at the right source when the problem occurs. Measuring could allow a provider to take proactive steps and perform network re-balancing in such a way to dissipate bandwidth hogs’ effect on the network.”

Thankfully, a solution like Talari’s Software Defined THINKING WAN can make all the difference when it comes to these killer apps. The solution measures the availability of each path across the networking, ensuring that the traffic connected with these killer apps is prioritized and takes the most optimal path from user to user.

Let’s take a look at some of today’s real-time apps, and how each is impacted by the underlying WAN.

Voice: First up is voice since Voice over IP (VoIP) has taken the place of most legacy telephony systems across the enterprise sector. Now that VoIP plays such an important part of a company’s communication infrastructure, it’s essential that the proper support is in place.

“A single call needs bandwidth speeds of 3 Mbps up and down.”

A number of enterprises run into issues with their VoIP service, including low call quality, dropped calls or delay. Recently, Talari helped Chicago-based real estate management company Equity Office improve its VoIP with an industry-leading WAN solution. With the technology in place, VoIP traffic is prioritized to ensure that it takes the path offering the least latency and jitter, as well as the best availability. This prevents delay and improves call quality, while helping to guarantee that traffic can be rerouted in the event of a link failure or even link degredation for an uninterrupted experience. Since voice uses relatively little bandwidth, some customers choose to duplicate packets and send them across two disparate links. The one that arrives first is used and the late arriver is discarded. Unless a given packet is lost on both paths the packet loss goes to zero and the latency is the fastest of the two paths in real time.

UC: Unified communications systems are another demanding network consumer, particularly considering their constant, real-time activity needs. Oftentimes, remote workers or employees at different branch locations rely on their UC platforms to ensure constant communication and collaboration. However, a missed message or an inaccessible UC platform can cause severe issues across an organization.

UC is another example of a real-time app that can be better supported with Talari. Talari’s technology, including it’s family of network appliances, helps businesses make the most of all of their available links, be they MPLS, Internet or a mix creating a hybrid WAN. Even links that were solely utilized for backup can be treated as active paths across the network, helping to put an end to network outages and guaranteeing continual support.

Video: Video has become an increasingly critical part of enterprise activity, whether leveraged for training purposes or for communication via videoconferencing suites. Bourque noted that video platforms, including conferencing and streaming services, are “by far the largest bandwidth user” within a business’s network, and the needs connected with these critical programs will only grow in the near future.

“The video segment will be the single most demanding bandwidth application [going forward],” Bourque told InformationWeek.

At the same time, video platforms are also some of the most sensitive applications. Performance issues can stem from a number of causes, including latency, jitter and availability, creating grainy, delayed videos that communication or collaboration incredibly frustrating and basically worthless.

Don't let "fail" describe your WAN.Don’t let this describe your WAN.

With a Talari solution in place, however, these problems simply go away. Video traffic can take advantage of using multiple paths simultaneously to make sure that it travels across a high quality path with the least latency and jitter. This considerably improves the performance of video-based tools, including streaming training videos and videoconferences, offering a continually smooth experience for users.

While these are some of the most well-known real-time apps, they certainly are not the only apps business depends on. Even email and virtual desktop platforms can utilize more bandwidth than many administrators might realize, requiring measurement and traffic prioritization to prevent performance problems or inaccessibility. Unlike WAN Op, Talari’s THINKING WAN can improve the performance of real-time, interactive and bulk traffic so the applications employees and businesses count on are available and working as expected. With a Talari solution in place, network and application performance problems simply go away.
