"Orchestrator Blues" Part 3: Edge Remote Diagnostics and NATted VCO address

 

If an Enterprise uses its own Orchestrator (VCO) the device is often placed inside the internal Datacenter (DC) network and has a private internal Eth0 address configured.

Therfore the internet facing Firewall in the main Data Center will have a static 1:1 translation between the public IP address used by SD-WAN Edges and the private IP address used by the VCO.

In my lab Edges are reaching the Orchestrator via 110.1.1.254 and the RO-230-IOL-Entry router will translate it to 10.8.1.254 the VCO address on Eth0.

In such cases you need a specific additional system property set to make remote diagnostics to work


 as you see you also need to set the network.portal.websocket.address


Then Remote Diagnostic access from your browser using the internal private address and edges using the public address should work.

Orchestrator Upgrade to Version 5.2

Image
 Recently I upgraded my VMware SD-WAN lab from version 5.0 to 5.2. Since some previous versions the official documentation  recommends to ask TAC for help in upgrading.   Docu 5.2: Orchestrator Upgrade  But if you have an unsupported implementation, like I do, you need to do it on your own: Trying to copy the new version to the VCO failed and I found out that I needed to increase a disk volume How to increase disk volume on VCO is described in this blog:   VCO Upgrade to 4.5.x After increasing the disk size my copy succeeded   NOTE: I did not copy direct to the installation directory including a renaming, as once an upgrade started that file gets deleted and if there are any problems to have to redo the copy from outside.  vcadmin@vco-lab-254:~$ ls -l total 2504488 drwxr-x--- 2 root    root          4096 Aug 31  2022 20220831130007 -rw-rw---- 1 vcadmin vcadmin 2564587520 Aug 10 07:57 vco-debs-signed-5.2.0.3-R5203-20230809-GA-ff5cd1917e.tar vcadmin@vco-lab-254:~$ sudo cp vco-debs-signed

Deep Dive on DMPO and its Performance Features (available and missing) Part 1

Image
 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 links have  both 10

Deep Dive on DMPO and its Performance Features (available and missing) Part 2

Image
  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 of buffers is limited and/or when the client is n
