What is an IP VPN?<\/h3>\n\n\n\n
An IP VPN<\/strong> is a private network that is set up for you on a shared IP-based backbone of a telecommunications provider. It is based on MPLS technology. The abbreviation VPN stands for virtual private network. In contrast to private networks, which are based on individual point-to-point lines, the private network in a VPN is only created virtually. Individual customer networks are set up virtually on the backbone of a telecommunications provider’s network. This is of course much cheaper and more flexible than setting up dedicated, complex point-to-point routes for each customer. IP VPNs differ from the extensive product group of VPN technologies in that the data is transported via a so-called IP network. Let us now take a look at some of the key advantages of IP VPNs.<\/p>\n\n\n\n
Advantages of an IP VPN<\/h3>\n\n\n\nWith IP VPN, your company network benefits from at least one of the following aspects. Cost reduction compared to more expensive point-to-point services. Connection of locations where no private network, i.e. dedicated connections, are available, e.g. in remote areas, abroad or in areas with limited infrastructure. In Germany, there are many places where there is no fiber optic<\/a> and therefore no dedicated line available. A further advantage of IP VPN can unfold during network rationalizations. For example, two networks can be merged in the event of mergers or takeovers of other companies. A major driver for IP VPN is also the merging of voice and data traffic<\/a> into one network. The cost-efficient and secure connection of small locations and remote users can also be an issue.<\/p>\n\n\n\n
Comparison of IP VPN to Ethernet Private Network (EPN)<\/h3>\n\n\n\n
If you compare managed IP VPNs with EPNs, some key differences emerge. Since managed IP VPNs are mapped in the carrier network on a shared platform, they are more flexible than private networks, which are much more difficult to adapt to changes in the company’s bandwidth requirements, for example. This is much easier in a shared network that is also open to two carriers. There are often no high costs and restrictions when adapting. An example: For a customer, we connect all locations with 100 Mbit\/s carrier links, of which only 50 Mbit\/s are initially used and paid for. If demand increases, the available bandwidth can be immediately adjusted up to 100 Mbit\/s. The same can of course also be done with higher bandwidths. Let us now look at the possible network topologies. In addition to Hub and Spoke and Point to Point, Any to Any networks can typically also be mapped in the IP VPN. IP VPN also offers a greater choice in terms of the access technologies used. SDSL, Wifi, leased line, LTE, UMTS or radio relay are all easy-to-integrate network connections. The five different service classes in the IP VPN make it easier to control the quality of the individual applications in the network, such as data, voice, video or storage, in a targeted manner and to ensure that all services within the network run smoothly. This makes IP VPN an attractive option for companies to manage their in-house network for a large number of locations.<\/p>\n\n\n\n

How SAVECALL supports your IP VPN<\/h3>\n\n\n\n
<\/div>\n\n\n\n
SAVECALL advises vendor-neutral and provider-independent on the design and procurement of your IP VPN. Based on more than 80 carrier partnerships, we compare providers, access technologies and service classes and find the right topology for your locations. With our location check we give you an overview of the available IP VPN providers for your site and support you from analysis to implementation.<\/p>\n\n\n\n
<\/div>\n\n\n\n
Conclusion: IP VPN as flexible site connectivity<\/strong><\/h3>\n\n\n\n
<\/div>\n\n\n\n
IP VPN connects company locations securely and cost-efficiently over a carrier’s shared IP backbone, without your own physical lines. Compared to EPN it scores with more flexible bandwidths, free topologies and a wider choice of access technologies. This makes it an attractive basis for managing your in-house network across many locations. In part 2 of this series, we go deeper into the practical implementation.<\/p>\n\n\n\n

Frequently asked questions about IP VPN<\/h3>\n\n\n\n
What is an IP VPN?<\/strong>
An IP VPN is a virtual private network set up for you on the shared IP-based backbone of a telecommunications provider. It is based on MPLS technology. Instead of building dedicated point-to-point lines for each customer, individual customer networks are created virtually on the carrier backbone. This is much cheaper and more flexible and enables secure site connectivity without your own physical lines.<\/p> <\/div>
How does IP VPN differ from an Ethernet Private Network (EPN)?<\/strong>
A managed IP VPN is mapped in the carrier network on a shared platform, which makes it more flexible than a private EPN. Bandwidths can be changed quickly and without high adaptation costs. IP VPN also supports more network topologies such as hub and spoke, point to point or any to any, and offers a wider choice of access technologies. EPN, in turn, provides dedicated, clearly separated resources.<\/p> <\/div>
What are the advantages of an IP VPN?<\/strong>
IP VPN reduces costs compared to more expensive point-to-point services and connects locations where no dedicated line is available, for example in remote areas or abroad. It helps with network rationalization, such as merging two networks after a takeover. The merging of voice and data traffic into one network and the connection of small sites and remote users are also typical drivers.<\/p> <\/div>
Which access technologies can be integrated into an IP VPN?<\/strong>
IP VPN is very flexible when it comes to access technologies. It can integrate SDSL, WiFi, leased line, LTE, UMTS or radio relay, among others. This makes it possible to connect locations where no fiber optic and therefore no classic dedicated line is available. This variety makes IP VPN especially attractive for heterogeneous site landscapes and international networks with differing local infrastructure.<\/p> <\/div>
How does an IP VPN support different applications such as voice and video?<\/strong>
An IP VPN typically has five different service classes. These make it easier to control the quality of individual applications in the network in a targeted way, for example data, voice, video or storage. Time-critical services such as voice and video are given priority, while less critical applications are treated with lower priority. This ensures that all services within the same network run smoothly.<\/p> <\/div>
