There are many values and recommendations, but as far as I understand the real question is what is the actual MTU of the WAN link which depends on the type of connection (cable, PPPoE, etc.). Starting from this MTU, I should be able to calculate the optimal MSS value to be set for my LAN interfaces, right?

In 2019, it became clear that SD-WAN had secured its position as the way forward for enterprise WAN connectivity. Market adoption is growing rapidly, and industry experts have declared a winner in the SD-WAN vs MPLS debate. SO WHAT IS SD-WAN? Whats driving all the excitement around SD-WAN?

For the past two years, Cato Networks has led a revolution in enterprise networking: the convergence of software-defined wide area networks ( SD-WAN ) and network security delivered as a single cloud service. For decades, networking and security evolved as silos, creating separate point products in each category.

Not all network traffic is created equal. Luckily, SD-WAN can be configured to prioritize business-critical traffic and real-time services like Voice over Internet Protocol (VoIP) and then effectively steer it over the most efficient route. The good news is many SD-WAN solutions offer built-in security. IMPROVES PERFORMANCE.

Traditional hub-and-spoke networking has enterprises backhauling WAN traffic from branches over MPLS circuits to a central site and applying security policies before sending the traffic to the cloud or the public Internet. SD-WAN has emerged as a popular alternative to MPLS.

And, as most real-time conversations last orders of magnitude longer than most other types of internet interactions, the probability of a network incident impacting the packet transmission is dramatically higher. The challenge is that in the network world getting Service Level Agreement (SLA) determinism generally has a steep price.

When more of the workforce shifts to working remotely, it puts new and different strains on the infrastructure across different parts of the network, especially where VPN gateways connect to the network edge. This could mean the users are saturating the internet connectivity or that they’ve saturated the LAN (or maybe WAN).
