Crazy about VMware SD-WAN

  The following Features will be discussed in this second part of my blog TCP Optimization Techniques Dejitter Buffering SAAS Application Monitoring   Before diving into the mechanism here an important basic fact:     Remediation is never done for applications classified as LOW priority     TCP optimization TCP has some embedded traffic management capabilities for reliable traffic delivery  (window.size, slow-start, RTT handling,...)  But there are a bunch of factors which can negatively influence the performance, like Latency TCP-slow-start Last Mile network problems Out of Sequence packets Busty losses end host TCP limitations (missing fatures like SACK, windows scaling or timestamp options)  Typically TCP optimization helps on the transmission side and improve the download time for large data transfers over latency-high and lossy WAN links. But it can also be used for improving perfomance when on the receiver side the amount ...

 In the last year I got quite deep insight into ther vendors SD-WAN implementation and also have seen what various vendors are critizising about the VMware DMPO features. Also there are a lot of misconceptions on the market around some of these features. So let´s try and evaluate and look a little bit deeper into typical performance features and the VMware implementation of them Features discussed in this Blog (Part 1) Per Packet Load Balancing Forward Error Correction (FEC) Packet Replication Latency Remediation The following Features will be discussed in Part 2 of my blog TCP Optimization Techniques Dejitter Buffering SAAS Application Monitoring   Per Packet Load Balancing  Unfortunately this term can be quite easily misinterpreted, when you Google for the term and get the following result:  This behaviour (often criticized by other vendors about VMware) as described above would only work quite well when you have very similar or equal connections. If for example 2 ...
