Can SD-WAN Solve Your Low Bandwidth Problem?
Author: John SheplerCan SDN or SD-WAN solve your problem of low and unreliable bandwidth? Hi, You can now solve your bandwidth problem by switching to a higher bandwidth dedicated service SLA eg. B. Ethernet before fiber optic lead carrier. The better question is how SD-WAN can give you faster and better bandwidth at a cheaper cost.
Causes of low and unreliable bandwidthBusinesses with bandwidth issues generally fall into one of two categories. The first, due to a very limited budget, chose cheap basement options. Others are frustrated that the services they need are not available in some places and at any price.
The ultra-cheap options are usually broadband services developed for the cost-conscious consumer market and then rebranded as enterprise. This of course includes DSL and cable broadband, but can also include cellular and some two-way satellites.
What these services have in common is that the bandwidth pool is shared by multiple users that are currently online. This causes your speed to fluctuate throughout the day. They are also usually online only. If you need point-to-point, you should create an encrypted tunnel with a VPN or use your own security. Finally, they are generally offered as "best effort" information services without any warranty of availability or performance.
Aren't all services regulated by poor quality telecommunications?
no This is unfair and wrong. Cable speed and performance have improved dramatically, especially since the introduction of DOCSIS 3.0 and now 3.1. Fiber optic speed is available cheaply in many places. Reliability usually depends on local service providers. Some of them have almost perfect runtime. Others are less reliable.
Likewise, cellular and wireless satellite communications have seen technological advances over the years. Both suffer from low bandwidth, congestion and spotty service. It is not a big problem. With 4G and now 5G wireless technologies, fiber optic speeds with reliable service are becoming commonplace. Satellite now also carries nationwide 100 Mbps gigabit service. A point beam provides very reliable attenuation limits.
Cellular and satellite communications have their limitations, but satellites have latency issues that will only be solved with a low-orbit constellation. Both services are bandwidth-limited by the available spectrum, so there's not much to do. This means limiting data so that some users don't use scarce resources. If you reach the limit, you pay more or your bandwidth is limited until the end of the month.
What can SD-WAN do with these limitations?
SD-WAN or Software Defined Wide Area Network, which is part of Software Defined Networking (SDN) technology, cannot change the laws of physics, provider unreliability or service availability. It can manage a limited number of bandwidth options to create a single network with better performance.
This works because every connection you make will not have the same latency, packet loss, speed or reliability. Despite inherent technological differences, performance often changes over time. Sometimes the cables run very fast. Sometimes things get stuck. The same goes for WiFi, satellite and even ADSL.
No one can sit at a switch and travel fast enough to immediately send every packet along the best or most convenient path. The calculator can: This is SD-WAN. CPU-driven software controls multiple channels. Then there is a plan for where to route the traffic and everything is tracked.
No more SD-WAN mysteries
Another thing that makes SD-WAN effective is that not all traffic is so demanding. VoIP voice calls are very sensitive to delay and packet loss. No data file backup. Many cloud-based business applications require consistently high performance. Some are not so picky. Given this, the SD-WAN controller can see which requests need to be served, which paths are available, and with what bandwidth. It can choose where to send traffic to make the most of the resources you provide.
SD-WAN connectivity options include DSL, cable, T1 connections, satellite, 4G or 5G wireless, point-to-point microwave, Ethernet copper or Ethernet fiber, and even SONET fiber connections. The right combination depends on the performance you need, the connections you have, and your bandwidth budget.
Are you struggling to run a business because your current bandwidth solution is insufficient? You should know that now that SD-WAN is here, you have more options than ever. Talk to a network bandwidth consultant about your specific business needs and see if you can do better than what you're doing now.
