#78: GNS3 API: Jeremy explains how the API works
Jeremy Grossmann (creator of GNS3) discusses the GNS3 API with David Bombal. How it works, what you can do with it and where to learn more information. All communication in GNS3 uses HTTP using the JSON format.

#77: Jeremy explains the GNS3 2.2 Architecture
How does the GNS3 work? Jeremy (creator of GNS3) explains the GNS3 architecture. Note: The Server component is also called the Compute Server or Compute. GNS3 consists of four parts: - the user interface or GUI (gns3-gui or gns3-web projects) - the controller (gns3-server project) - the compute server (part of the gns3-server project) - the emulators (Qemu, Dynamips, VirtualBox…) The controller pilots everything, it manages the state of each project. Only one controller should run. The GUI displays a topology representing a project on a canvas and allow to perform actions on given project, sending API requests to the controller. The compute controls emulators to run nodes. A compute that is on the same server as the controller is the same process. The compute usually starts an emulator instance for each node.

#76: GNS3: Docker containers vs Virtual Machines
Why would you use Docker containers rather than Virtual Machines (VMs) in GNS3? Which is best? And which hypervisor should you use? VMware or VirtualBox? What about QEMU? Jeremy (creator of GNS3) shares his advice on what you should be using.

#75: GNS3: What is QEMU? And IOU? And ASA 8.x?
What are QEMU and IOU devices in GNS3? What does Jeremy (GNS3 Creator) recommend we use? Does QEMU only support VIRL? Or are other vendors supported? What about ASA 8.x? Is that supported? #gns3 #virl #iou

#74: Will Dynamips and VPCS be removed from GNS3?
David Bombal talks to Jeremy Grossmann (creator of GNS3) about the future of GNS3. Here we discuss Dynamips and VPCS and their future in GNS3. Will they be removed from GNS3? Are they recommended? What do they actually do? What should be used instead of them? Does Dynamips support switching? In future videos we will discuss additional options in gns3 such as Cisco VIRL and IOU. Menu: 0:12 - Devices in GNS3. It can be confusing. What is Dynamips 0:57 - Does GNS3 support switching? 1:17 - Are they real IOS images? 1:47 - Issue 1: Where do I get Cisco images? Cisco restrictions. 2:07 - Issues 2: Only older versions of Cisco IOS are supported on a lot of platforms 2:11 - Is it stable? Issue 3: More memory and processor intensive 2:25 - What is Idle PC Value 4:23 - Advantage 1: Supports serial interfaces 4:50 - Dynamips is a dying product 5:00 - You can run Dynamips locally 5:40 - What does Jeremy recommend we use? 5:50 - Switching in Dynamips? 7:18 - Will Dynamips be removed from GNS3? 7:48 - What is VPCS? 8:28 - What is the advantage of VPCS? 8:55 - Should we be using VPCS? 9:58 - Will VPCS be removed from GNS3?

#71: Visio Alternative? GNS3 interactive topology diagrams
Is this a replacement for Visio? GNS3 now allows you to create interactive topology diagrams. You can create topologies consisting of both physical and virtual devices and get them to communicate with each other. Will gns3 replace visio? How will you make the most use of this new feature in gns3? #gns3 #visio #ccna
