Congestion and a Lack of Bandwidth
Bandwidth is often an unseen network trouble maker and learning how to increase it can be the secret to business success. When you have enough, you never give bandwidth a second thought. But the moment you start experiencing congestion, slow applications, sluggish connections, interrupted calls or remote desktop sessions, insufficient bandwidth is often the culprit. Seeing this issue, quantifying your true business needs and adding the correct bandwidth are all things Ecessa SD-WAN can solve.
Many companies spend time and money attempting to optimize their limited bandwidth. Ecessa SD-WAN solutions allow for an easy, seamless way to add new bandwidth while making the most of all available bandwidth.
Use all your new Bandwidth WITH SD-WAN
SD-WAN leverages any and all connection or transport types, allowing users to make the most of any connection available to them, including DSL, Cable, Fiber, MPLS, Cellular (4G/5G), Satellite, Fixed Wireless or Microwave connections. Ecessa solutions are purpose-built, guiding traffic down any available connection, thus allowing your business an active/active network with all bandwidth being utilized. Instead of letting connections sit idle, waiting to kick in during an outage (the traditional failover configuration) all available connections are used at all times.
There are two types of routing to achieve this result; Session Load Balancing and Packet Aggregation. Both have pros and cons:
Session Load Balancing
Individual sessions are sent down different connections in real time, essentially spreading traffic out and using all available bandwidth. The downside to this approach is that if an outage occurs on connection 1, any sessions already on that link will be lost. To avoid this, packet-level duplication can be used.
This approach takes individual sessions, breaks them up and sends each packet down different connections in a round robin fashion. This has the potential to squeeze the most bandwidth out of all existing connections; typically advertised as doubling bandwidth or discussed as WAN optimization. The downside to this approach is that if the existing WAN connections are not identical in performance, that is packet loss, latency, re-ordering or jitter are not the same, packets may be delayed or out of order, resulting in a slower overall performance than expected.
The experts in Ecessa Technical Support can take you deeper on these subjects and assess your unique network to see what types of routing configurations are best for you.
