Components of GigaVUE Cloud Suite for OpenStack

The GigaVUE Cloud Suite for OpenStack includes the following components:

■

GigaVUE® Fabric Manager (GigaVUE-FM) is a web-based fabric management and orchestration interface that provides a single pane of glass visibility, management, and orchestration of both the physical and virtual traffic that form the GigaVUE Cloud.

GigaVUE-FM can be installed on-premises or launched from an OpenStack image. GigaVUE-FM manages the configuration of the following visibility components in your OpenStack project:

• UCT-V Controllers (only if you are using UCT-V as the traffic acquisition method)
• GigaVUE V Series Configuration
  • GigaVUE® V Series Proxy
  • GigaVUE® V Series Nodes

■

UCT-Vs (earlier known as G-vTAP Agent): An agent that is installed in your virtual machines. This agent mirrors the selected traffic from the virtual machines to the GigaVUE V Series Node.

■

UCT-V Controller (earlier known as G-vTAP Controller) manages multiple UCT-Vs and orchestrates the flow of mirrored traffic to GigaVUE V Series nodes. GigaVUE-FM uses one or more UCT-V Controllers to communicate with the UCT-Vs. UCT-V Controllers

■

GigaVUE® V Series Proxy manages multiple V Series nodes and orchestrates the flow of traffic from GigaVUE V Series nodes to the monitoring tools. GigaVUE-FM uses one or more GigaVUE V Series Proxies to communicate with the GigaVUE V Series nodes. The GigaVUE V Series Proxy is a optional component. If GigaVUE-FM cannot directly reach the GigaVUE V Series Nodes (management interface) directly over the network, a Proxy should be used. A single GigaVUE V Series Proxy can be launched to provide the GigaVUE-FM network communication to hundreds of GigaVUE V Series Nodes present in private networks behind the Proxy.

■

GigaVUE® V Series Node is a visibility node that aggregates mirrored traffic. It applies filters, manipulates the packets using GigaSMART applications, and distributes the optimized traffic to cloud-based tools or backhaul to GigaVUE Cloud using L2GRE, or ERSPAN, or VXLAN tunnels.

■

Next generation UCT-V (earlier known as Next Generation G-vTAP Agent) is a lightweight solution that acquires traffic from Virtual Machines and in-turn improves the performance of the UCT-V mirroring capability. The solution has prefiltering capability at the tap level that reduces the traffic flow from the UCT-V to GigaVUE V Series Node and in-turn reduces the V Series load. Next generation UCT-V gets activated only if the kernel version is above 5.4. If the kernel version is less than 5.4 TC based mirror solution is deployed. Some of the points to be remembered while deploying the Next generation UCT-V are as follows:

•

Tapping/Tunnelling features are not fully supported in all the linux kernel version.

•

The support for Windows is relatively new and does not tap the packets. No change in data acquisition is planned for Windows agent.
