A Simple Solution for Redundant Internet:
Single Provider Multihoming
Using the same provider-assigned public LAN IP addresses on two circuits
The Internet is the backbone of modern business infrastructure. However, if this connection is interrupted, it can have a significant impact on business operations. For this reason, many companies are adopting a redundant Internet solution to ensure stable connectivity.
Hurdles in Implementing Redundant Connectivity
Simply put, two separate Internet circuits are needed for redundant connectivity. If one circuit fails, traffic should automatically be switched to the other to maintain Internet connectivity. This is crucial to avoid downtime and disruption to business operations.
However, to actually achieve that goal, a business typically has these challenges before them:
- Choose two Internet circuits from the vast number of providers available
- Confirm that circuits do not overlap or have a single point of failure
- Set up a network with two different sets of public IP addresses—each belonging to a different Internet service provider (ISP)
- Find a solution to automatically swap from one set of provider-assigned IP addresses to the other in the event of a circuit outage
Creating a network with redundant Internet connectivity requires precise engineering and can introduce the need for specialized equipment, leading to extra costs and future headaches should something go wrong.
Not to mention that businesses must pay for and manage the services of multiple ISPs. Dealing with two sets of IP addresses and separate support teams further increases the complexity of network management.
Benefits of Using the Same IP Addresses on Both Circuits (Multihoming)
If the same public IP addresses assigned to the Local Area Network (LAN) can be used on both Internet circuits, switching during an outage becomes much easier and faster. With this configuration, LAN hosts keep their same IP addresses, and standard router equipment can simply send their traffic to the backup circuit. Plus, incoming connections swiftly reach the LAN hosts over the backup circuit using the same IP addresses. This solution helps quickly restore Internet connectivity and simplify network management.
Unfortunately, since most businesses use IP addresses tied to their ISP, they must deal with different addresses when multihoming with two ISPs. What’s more, most ISPs do not even support using the same IP addresses on two of their own circuits!
PacketFabric's Redundant Internet Solution
PacketFabric offers an innovative redundancy service with the following features to overcome these issues:
Time Savings and Cost Reduction by PacketFabric
Selection of the redundant infrastructure, namely the Internet access points and access lines, will be done by PacketFabric. PacketFabric contracts, installs, and monitors the access lines on the customer’s behalf—greatly reducing the burden on your business and potentially saving on access line costs.
Furthermore, PacketFabric offers a significant discount for the backup circuit: The Internet connectivity fee for the backup circuit is only 10% that of the main circuit.
Same LAN IP Addresses for Main and Backup Circuits
In a typical multihoming setup, a business borrows public IP addresses from two providers which can only be used on each provider’s circuit. Thus, manual switching or costly specialized equipment is required to maintain connectivity when one circuit fails. With PacketFabric’s redundancy solution, LAN hosts can use the same IP addresses for both the main and backup circuits, allowing you to easily set up redundancy using standard routers
