Listen to Podcast about How to Select SD-WAN
Podcast – How to Select a SD-WAN System On this podcast, I discuss with the Packet Pushers hosts, how to shop for an SD-WAN. You may have noticed that SD-WAN products are a bit hard to tell apart, at least at a glance. Most of them seem to have a central controller, a policy manager, x86 boxes that […]
How to calculate the Latency of a Wide Area Network or IEPL
When evaluating a carrier for your MPLS network or IEPL, you may find that some carriers will only provide transit delay (latency) statistics from their PE to PE, not from the customer edge to customer edge. The general rule is to add a local loop delay metric for each side of the path in question to calculate […]
Global WAN In Just Weeks
If you are looking for a fast SD-WAN installation that includes WAN Optimization, a core Layer-2 global network, great performance, with no capital investment, this solution is worth exploring. Installation can be completes in just weeks. All Aryaka POPs are connected to one another using multiple links and carriers to deliver reliable, enterprise-grade, full-mesh connectivity. These POPs also have […]
How Does SD-WAN Work?
SD-WANs have the potential to reduce your WAN costs by up to 90% if you are using an MPLS network today. How is this possible? Sometimes, a picture says more than words. Or at least makes it easier to understand. Let’s say you have an MPLS network today. You can add low cost broadband internet and LTE […]
SD-WAN – Will the Cloud Kill WAN Optimization?
SD-WANs are not WAN optimization. They solve a different problem from WAN optimization. And yet walking along the floors at the ONUG conference hearing about SD-WANs and service chaining, I couldn’t help but think that software-defined WANs (SD-WANs) are the death of WAN optimization in branch offices. WAN Optimization We started using WAN optimization at a time […]
WAN Throughput Calculator
Here is a very helpful Throughput Calculator to help you understand the relationship between latency, packet loss and throughput. This also helps you understand how WAN Optimization can increase your WAN throughput. » Launch Calculator Calculate your WAN throughput and optimization potential. » Launch Calculator
SD-WAN, Hybrid WAN, and MPLS: What’s the Difference?
We’ve been discussing using the Internet as part of your overall wide area network (WAN) strategy. One of the questions I get asked with some frequency is something along the lines of “Steve, how does a software-defined WAN (SD-WAN) differ from a hybrid WAN and how’s that different from what I’ve been doing until now?” Let me […]
Reduce MPLS Costs With SD-WANs With Better Resiliency
Reduce MPLS costs? You may wonder…”did I read that correctly”? You did. You can have a enterprise class WAN without MPLS, though connectivity to China is another story! New technologies are changing the way that many companies provision their wide area networks. WAN requirements are changing. All companies have: A continued need for more capacity An increased […]
Out of Band Management with LTE
Out of Band Management or OOBM is a valuable tool for enterprises with many locations to manage remotely. It addresses building a highly resilient network infrastructure with proactively avoiding network disruptions. When time is money, a wireless fail-over solution will provide secure, remote console Out-of-Band Management. Out-of-Band Management to the console port of the primary router is a value-added layer […]
SD-WAN or MPLS: Which is Right for Business Voice?
In our last post, we discussed the general differences between MPLS and Internet-based VPN services. It’s not that one is necessarily “better” than the other. It’s more of a matter of the problem. Some issues are better addressed with the Internet VPN, some with MPLS, and some with a combination of both. Let’s start with one of […]
