Understanding WAN Redundancy Options
When it comes to WAN redundancy, organizations have multiple options to choose from. One popular approach is the use of Software-defined WAN (SD-WAN) technology. SD-WAN allows for the interconnection of multiple WAN links onto one or more Software Defined Networking (SDN) devices. This provides load balancing and redundancy, ensuring that even if one link fails, others can seamlessly take over the traffic.
Another way to achieve WAN redundancy is through multiple WAN connections. This can be done using equal-cost routing or gateway redundancy protocols. With equal-cost routing, traffic is split across multiple WAN links, providing redundancy for outbound services. Gateway redundancy protocols, on the other hand, allow for the automatic failover to a secondary gateway in case the primary one becomes unavailable.
Organizations can also opt for different WAN configurations, depending on their specific requirements. These configurations include single homed, dual homed, single multi-homed, and dual multi-homed setups. Each configuration offers different levels of redundancy, allowing businesses to choose the one that best suits their needs.
WAN Redundancy Options

Importance of Redundancy for Outbound and Inbound Traffic
Redundancy plays a crucial role in ensuring reliable connectivity for both outbound and inbound traffic in cloud-based PBX systems. When it comes to outbound services like web browsing, email communication, cloud services, and hosted VoIP services, having multiple WAN connections is essential for maintaining uninterrupted connectivity. In the event of an ISP or network failure, redundant WAN connections provide backup routes to ensure that outbound services can continue without disruption.
There are different WAN redundancy deployment scenarios that can be utilized to achieve redundancy for outbound services. One option is to use equal-cost routing, where multiple WAN connections are configured with the same cost, allowing traffic to be distributed across them evenly. Another option is to implement gateway redundancy protocols, such as Hot Standby Router Protocol (HSRP) or Virtual Router Redundancy Protocol (VRRP), which provide automatic failover in case of a primary gateway failure.
While outbound redundancy is crucial, it is equally important to ensure redundancy for inbound traffic. Inbound traffic refers to connections coming into the organization’s network, such as incoming calls or requests for internal services hosted on the network. To achieve redundancy for inbound traffic, organizations can utilize routing protocols like Border Gateway Protocol (BGP) to define primary and secondary routes. This ensures that incoming traffic can be routed to an alternate path in case of an ISP failure or network disruption.
Table: WAN Redundancy Deployment Scenarios
| Redundancy Scenario | Description |
|---|---|
| Equal-Cost Routing | Multiple WAN connections with the same cost are used, allowing traffic to be distributed evenly across them. |
| Gateway Redundancy Protocols | Protocols like HSRP or VRRP provide automatic failover for gateway devices in case of a failure, ensuring uninterrupted outbound connectivity. |
