Osi Layer 3 Ppvpn Architectures


This section discusses the main architectures for PPVPNs, one where the PE disambiguates duplicate addresses in a single routing instance, and the other, virtual router, in which the PE contains a virtual router instance per VPN. The former approach, and its variants, have gained the most attention.

One of the challenges of PPVPNs involves different customers using the same address space, especially the IPv4 private address space. The provider must be able to disambiguate overlapping addresses in the multiple customers’ PPVPNs.


In the method defined by RFC 2547, BGP extensions advertise routes in the IPv4 VPN address family, which are of the form of 12-byte strings, beginning with an 8-byte route distinguisher and ending with a 4-byte IPv4 address. RDs disambiguate otherwise duplicate addresses in the same PE.

PEs understand the topology of each VPN, which are interconnected with MPLS tunnels either directly or via P routers. In MPLS terminology, the P routers are Label Switch Routers without awareness of VPNs.

Virtual router PPVPN

The virtual router architecture, as opposed to BGP/MPLS techniques, requires no modification to existing routing protocols such as BGP. By the provisioning of logically independent routing domains, the customer operating a VPN is completely responsible for the address space. In the various MPLS tunnels, the different PPVPNs are disambiguated by their label but do not need routing distinguishers.

Unrestricted Worldwide Internet Access

Keeping a VPN constantly connected means that you can have access to geo-restricted content from around the world. When you use a VPN, it connects you to a secure server in a location of your choosing, so it can make it look like you are in that country.

So if you want to watch Hulu or HBO Max but arent in the US, a VPN will let you bypass these restrictions from anywhere in the world. It will connect to an American server and create an American IP address to make it appear as though you are in the States, even if youre not. The other benefit of this is that you can switch servers seamlessly, so you can access an American server to watch Hulu, then switch to a British server to watch BBC iPlayer.

How Many Countries And Locations Does It Cover

The more countries a VPN supports, the more options youll have for swapping your IP address to new locations, accessing more content, and overcoming other geoblocking restrictions. You can hop around the world in a digital sense to avoid government censorship and view content unavailable in your country.

Always make sure that what youre doing over a VPN is legal, and dont use a VPN if it isnt legal to do so.

If theres a specific country youd like to have an IP address in, consult each VPN providers website to see whether or not theyll support your needs.

  • Avast SecureLine VPN: 34 countries, 55 locations

  • AVG Secure VPN: 36 countries, 56 locations

  • CyberGhost: 91 countries, 113 locations

  • ExpressVPN: 94 countries, 160 locations

  • IPVanish: 50 countries, 75+ locations

  • NordVPN: 59 countries

  • TunnelBear: 34 countries

What Is A VPN And How Does VPN Work

VPN creates a secure bridge from which your internet traffic passes, it encrypts your data while you perform your online activities on the internet, hiding and securing your online identity.

When you connect to a VPN, your original IP address is masked with a VPN servers IP address which is assigned to you. With this, everything you do on the internet remains anonymous. Your online identity is secure and your location is tweaked from which no one is able to trace or track you.

If you are not using a VPN, you are browsing with your original IP address, which is a risk. As you connect to a VPN, all your traffic goes through a secure tunnel. Even your ISP or the government wont be able to track you.

So it is necessary to use a VPN if you want your online identity to be safe.

How To Choose The Best Mobile VPN

Know Yourself

Whether you’re using an iPhone or an Android device, your first step is the same: find a VPN you like that’s compatible with your device. Here’s how:

1. Browse CNET’s lists of the best VPNs for iPhone and best VPNs for Android. If your aim is just to browse on public Wi-Fi securely, look for a VPN service that has servers located in your current country. The general rule of thumb is the closer the hardware, the quicker the connection.

2. Avoid free VPNs. We love 30-day guarantees and 7-day trial periods , but completely free VPNs are rarely safe, and are often just a way for unseemly companies to get hold of your data.

If you’re looking to invest in a VPN for the long haul, you’re going to need more than 10 minutes of research time. But when you’re ready to take a deeper dive, CNET has reviews of many of the major players in the VPN space, and a guide for how to pick the right VPN for you.

How Much Mobile Data Does A VPN Use

Understanding how much of your mobile data a VPN uses is vital, since this is basically what you really want to know by asking the main question in this post.

The amount of mobile data that a VPN uses depends entirely on the type of protocol you choose to connect to the VPN through. You see, every VPN provider offers multiple protocols to connect via, with the most common being L2TP, OpenVPN and PPTP.

Each of these protocols attribute differing levels of “overhead” to each data packet transmitted on your mobile device. To put this another way, L2TP uses more data than OpenVPN, with PPTP using the least data of the three.

A practical example of this was done by Quora user Rose Ab. She tested and tracked the VPN on her mobile device to monitor the difference in MB traffic when downloading the same file both with and without a VPN connection. Her results showed that by downloading a single 50.4MB HTTP file without a VPN, 51.5MB of data was used whereas 57.7MB was used to download the same file when connected to a VPN.

This is just one such example that potentially shows the level of data usage a VPN takes up, however there are a lot of variables to consider in order to really define the exact percentage of data usage a VPN takes up. With that said, lets take a look at some ways you can minimise the amount of data your VPN will use.

How Does A VPN Change My Ip Address

The way a VPN changes your IP Address is very simple. Connecting to a VPN, means you are connecting via an encrypted pathway, to a server located somewhere else .

When you connect to a website, that website can see the link back to that server, but it cannot see beyond that server back to your own personal internet connection. Therefore, the only IP Address it can see is that belonging to the server.

This means you are serving the web anonymously, as there is no way to connect you with the IP Address that you are using.

What Can A VPN Do For Businesses

In an era of business defined by security breaches, the best case scenario is keeping your business’ data is protected as possible. Unfortunately, with employees working from home and hybrid work becoming the new norm, it’s getting harder and harder to secure your business from cyber criminals. That’s where a good VPN comes in handy.

By funneling all your employee work through the private, encrypted tunnel that is a VPN, you’ll be able to ensure that your team isn’t compromising the security of your network by working at home or even at a coffee shop. It can protect customer data, internal documents, employees records, and virtually all other sensitive company information. Essentially, you’ll be enjoy end-to-end encryption across your company, so there’s very little risk of a breach.

In most cases, VPN providers even offer specific business-facing plans. These plans are typically priced on a per user per month basis, and offer additional business features, like a control panel to manage accounts, active directory integrations, and added layers of security like two-factor authentication and kill switches.

Safe Access To Public Wi

Public Wi-Fi networks are extremely vulnerable, making it easy for hackers to access your private information. Some cybercriminals will even set up rogue connection points on public Wi-Fi to spy on users and access their information. Without a VPN, your personal data and communications are at risk. A VPN will make it appear as though your data is coming from your connected server instead of your actual device.

You need a VPN to ensure the protection of your connection is second to none. If you have a VPN, it would take the fastest supercomputer millions of years to decipher the encrypted data. So not only does a VPN secure your actual connection, but even if your data was susceptible to attack from a vulnerable public Wi-Fi connection, there is no way your information will be readable.
