Route Analytics and Netflow – Technology For Managing IP Network Unpredictability

Today, businesses increasingly rely on applications to deliver top and bottom line results from greater business process automation, and individuals consume vast and growing amounts of IP-based media. As a result, enterprises and service providers are building larger and more redundant networks to ensure traffic delivery. Unfortunately, the resulting network complexity is causing them to hit the limits of traditional network management technology. The reason: IP is not inherently predictable.Why Aren’t IP Networks Predictable?IP’s distributed routing intelligence makes it efficient and at the same time unpredictable. IP routing protocols automatically calculate and manage traffic routes or paths between points in the network based on the latest known state of network elements. Any changes to those elements cause the routing topology to be recalculated dynamically. While this keeps IP networks highly resilient in case of network failures, it also creates endless variability in the active routing topology. A large network can be in any one of millions of possible active routing topology states. In addition, application traffic patterns are by nature unpredictable. Network problems – router software bugs, misconfigurations, hardware that fails (often after exhibiting intermittent instability) – can add to that unpredictability.The Challenge of Managing Complex IP NetworksWith routing and traffic changing dynamically over time, it is a real network management challenge to ensure predictably high application performance. Take troubleshooting for example: when an end user reports an application performance problem that doesn’t stem from an obvious hardware failure, the root cause of the problem can be quite difficult to figure out in a large, redundant network. IT engineers don’t know the route the traffic took through the network, the relevant links servicing the traffic, or whether those links were congested at the time of the problem. Even determining which devices serviced the traffic at the time of the problem in a complex network can be nearly impossible.Traditional Network Management Only Goes to a PointThe overarching architectural principle of traditional network management is to gather information on a vast number of different “points” in the network, then correlate various point data to infer clues about service conditions. They key mechanism for doing this is the Simple Network Management Protocol (SNMP), which gathers information from point devices such as routers, switches, servers and their interfaces.Clearly, “point data” is useful – for example, an interface or device that fails, runs out of memory, or is congested with traffic is important to know about. However, the sum of all this point data is much less than the whole picture. Just knowing that an interface is full of traffic doesn’t tell you why it is full. Where is the traffic coming from and going to? Is the traffic usually on this interface, or was there a change in the network or elsewhere that caused it to shift to this interface? If so, from where, when, and for how long? Without answers to these questions, there is no real understanding of the behavior of the network as a whole, which robs the point data of much of its contextual meaning. This lack of visibility not only impacts operations processes like troubleshooting, but also engineering and planning. For example, without understand network-wide dynamics, change management and planning can be fraught with errors that stem from not knowing how changing a particular device will impact the entire network’s routing and traffic.Route Analytics with Netflow-Visibility into Network-Wide Routing and Traffic DynamicsLuckily, there’s a way to peer into the dynamic behavior of IP routing and traffic flows using a combination of route analytics and Netflow technologies. Route analytics provides precise understanding of network-wide routing by passively peering with selected routers via routing protocols such as OSPF, IS-IS, EIGRP and BGP to receive all available routing information, then computing an always-up-to-date, network-wide map of all routers, links, advertised and withdrawn network addresses, and traffic paths. Every time the network changes in a way that impacts routing, the routing protocols provide real-time updates which keep route analytics completely accurate. Since route analytics understands all paths, it can very efficiently provide network-wide traffic information on all links by collecting Netflow data at key traffic sources such as data centers and Internet peerings, then map traffic flows over their actual pathsThe Benefits of Route AnalyticsRoute analytics provides a new and far more useful picture of network and service behavior that helps network managers ensure that their networks are adequately engineered to deliver a complex, changing matrix of application traffic at various service levels. For example, engineers can use route analytics to model a change of high priority traffic caused by the anticipated rollout of a new application. The simulated new traffic will be overlaid not on some abstract model, but on the traffic and routing matrix as it actually exists in the network. Depending on what it shows, engineers can catch potential impacts before moving ahead, or proceed with confidence in the rollout, knowing that the network will continue to support existing application requirements.Troubleshooting also gets much faster, since engineers can see the route/path that a particular application traffic flow traveled across the network at the time a problem occurred, then analyze all links to see if key applications or CoS were breaching their volume thresholds. If there was congestion, further analysis can show whether a routing issue caused traffic to shift, or, if additional, unexpected traffic was present, where it originated, its destination and the route that included the problem link. Even if a routing or traffic problem isn’t the root cause, knowing the precise path provides the most accurate possible starting point for examining devices and interfaces involved in servicing application traffic.

A Guide to Help You Pick the Best Air Purifier for Your Loved Ones

Holidays are around the corner. This is the time of year when people start purchasing gifts for their loved ones. If you are going to purchase an air purifier for someone you love, we have some helpful tips for you. If you want to purchase the best unit, you may be able to use this guide to your advantage. Read on to find out more.

1: Set Your Budget

Just like anything you purchase, make sure you have set your budget first. The price of the unit will vary based on a lot of factors, such as the capacity, filter type, features, and brand of the unit. If you don’t have a flexible budget, we suggest that you go for a product that is available to purchase for less than $300.

2: Consider the Needs of the Recipient

Your next move is to consider the needs of your recipient. If you are going to purchase this unit for everyday use, we suggest that you go for a unit that comes with a HEPA filter. On the other hand, if your loved one has a specific need, we suggest that you consider a specialized unit.

For example, if they are more prone to respiratory issues, such as allergies and infections, we suggest that you get a UV purifier for them. The devices are designed to neutralize viruses and bacteria.

3: Think About the Available Space

Another primary factor is to consider the available space in the office or house of the recipient. For example, if they need a general-purpose unit for a small apartment, you may want to consider a filterless unit.

On the other hand, if they have plenty of free space, you may consider a bigger unit that features a higher airflow rating. These units are powerful enough to cover a large face.

4: Consider Extra Features

Lastly, we suggest that you consider additional features that they will just love. For example, some units come with an indicator that turns on when the filter needs to be replaced. This will allow the user to change the filter so that the device continues to work properly.

So, you may want to consider these features before you place your order. These features may not be important to you, but your friend may just be over the moon.

Long story short, we suggest that you consider these four tips if you are going to purchase a gift for your loved one on these holidays. Since the air is full of pollution during winter days, nothing can make a better gift than an air purifier. Therefore, you should consider these tips before looking for an online or physical store to make your purchase decision.

The Significance of Pure Air Inside Your Home

Have you ever climbed up mountains? If so, what do you do when you reach the top? Most people open their arms, close their eyes, and take a deep breath. That is the special thing about clean and fresh air. You feel like taking a pause and inhaling fresh air. Over the past year, we have faced several waves of coronavirus. These days, we have been warned about another wave of this virus. Therefore, the importance of clean air has been increasing day by day. In this article, we are going to find out why air quality is important when it comes to our indoor environment.

The impact of pollution on your indoor air

No matter where you go, you will have to face the consequences of poor quality. Even if you are alone in your home, you will still be prone to polluted air. Every year, more than 1 million people lose their life because of air pollution.

According to some reports, India is among the top 10 countries in the world with the worst air quality. The effect of polluted air is more evident as people spend over 90% of their time inside their homes. Another research study found that residents are at a greater risk of covid-19.

As a matter of fact, indoor air pollution has become an international concern. We can say that pollution levels inside and in closed spaces are up to five times higher. Since most pollutants are not visible to the naked eye, you may not be able to aware of the dangers of dirty air.

Indoor air pollutants may be generated by common household items, such as cleaning agents, cooking fuel, furniture polish, pet dander, and paint. Apart from this, domestic appliances such as refrigerators and heaters may also be the common source.

Since homes are not airtight, air pollutants can easily get in. For example, smog, smoke, mold spores, and dust can get into your house through your windows or doors. Air conditioners can be used to cool down your rooms. But the downside is that they can also boost the movement of pollutants across your house.

What can you do to purify your indoor air?

Basically, air purifiers are simple devices that receive dirty air and put it out after passing it through powerful filters. Nowadays, you can choose from hundreds of air purification units available in the market. They are based on a wide range of technologies. They are available in different sizes to cover rooms of different sizes.

Nowadays, most types of air purifiers depend on HEPA technology. Initially, this technology was introduced in the 40s in order to capture pollutants from the air. Although these filters have been used for the filtration of particulate matter, they may not be that effective when it comes to eliminating volatile organic compounds.

Therefore, if you are worried about your health, we suggest that you invest in a type of device that comes with a HEPA filter. With these units, filtering your indoor air will be a piece of cake. Therefore, you can count on these devices to and ensure clean air inside your house.

Why Worry About Board Up Services?

Your home or business has been damaged by fire, flooding, or some other natural disaster. There are definitely areas that are exposed, and you’re waiting on your insurance to get started with the restoration process. What do you need to do while you’re waiting to get an answer about everything?

Emergency board up services are something that you may want to consider for the “in between” time. Why would you go through the time and money to get these additional services before you even start the restoration process? Here are some of the benefits of it.

Prevent Theft

One reason to consider board up services is because you don’t want robbers and thieves thinking that they have an easy target to go after. If you leave parts of your home or business open and vulnerable, it’s going to be simple for those people to waltz in there and take whatever they want that is still intact after your disaster. Boarding up your doors and windows, along with any gaps in the walls, can deter potential thieves and keep whatever is left at your property as safe as possible.

Prevent Rain, Snow, and Wind from Damaging the Property Further

All year long, rain and snowstorms can be a bit of an issue if your home or business is left open to the elements. In those cases, it’s going to be in your best interest to connect with emergency board up services as soon as you can. The last thing you need is for your restoration company to get into your home or business to find additional water, or to have to dig out several inches of snow before they start working. It can also prevent wind from going through your home or business, which also prevents additional damage from occurring during that waiting period.

Stop Animals from Getting Inside

Lastly, board up services can easily prevent animals from coming into your home or business. Many animal species are incredibly smart and opportunistic, and they may see your currently empty building as a great place for them to set up a den or shelter. But, if your home or business is boarded up, they will have fewer ways to get inside. Smaller animals may still find nooks and crannies where they can get in, so you’ll need to keep an eye out for them when you move back in. But, at least squirrels and mice are easier and safer to deal with than say, a raccoon, bear, or deer.

If you get professionals to board up your property, you can rest easy and know your home or business is safe, and that’s the bottom line. Many companies that sort out restoration services will also do everything that they can in order to board up and protect your home or business until they can start the restoration process. You just need to get in touch with them and let them know what sort of help you’ll need to take care of everything related to your home or business

Raise Capital With Private Investors

If you have launched your own startup, your first biggest challenge is to raise capital. Fortunately, you choose from a lot of options to raise the funds your business needs. Among all the sources, crowdfunding is one of the best ones as it helps redefine how startups can get off the ground. In this article, we are going to help you know the benefits of raising capital with private investors through a crowdfunding platform. Read on to find out more.

Benefits of raising capital with private investors

1. Funding is not equity-based

First of all, crowdfunding is not necessarily equity-based. Although startups have the liberty to use the equity in order to catch the attention of potential investors, It’s not required to give up ownership to collect capital.

The good news is that some platforms allow their members to apply a reward-oriented approach in order to raise capital. For instance, if your business deals in a specific product, make sure you hand over a few units to your prospective investors before you roll it out for the ultimate users.

2. Attracting potential investors is easy

With crowdfunding, you can attract a lot of potential investors without putting in a lot of effort. Although you can try for angel investors, keep in mind that this process can cost you a lot of time. The reason is that you will have to pitch your small business concept several times.

On the other hand, if you use a crowdfunding platform, you will have to post your business pitch in only one place. And this page will be ready by hundreds of investors from across the globe.

These platforms have a lot of useful features that may help startups collect funds from investors. So, attracting potential investors and raising capital will be much easier using crowdfunding platforms.

3. Higher visibility

Crowdfunding can help you make your startup more visible. Since marketing may consume a large chunk of your budget, it makes sense to use a crowdfunding platform instead. For potential investors, it’s easy to fund a crowdfunding campaign.
And these activities can help boost the visibility of your brand. Plus, you can also attract investors for your next funding rounds.

The Bottom Line

If you want to raise funds for your startup, crowdfunding can be the best choice. All you need to do is become part of a crowdfunding platform and you will be able to tap into the pool of potential investors. And this will help you kick start your business and make it a success in the industry.
