VNF Forwarding graph is used to illustrate the relationship between SDN controller and VNFs, based on the direction of traffic flow. The VNF Forwarding graph shows the forwarding logic of a given VNF. It shows the data flow and its path through the distributed components in a logical view. Three types of links connect nodes: input, output, or control. The VNF Forwarding graph enables the mapping of L3 and L2 forwarding tables to a software-based virtual network function (VNF) layer of network functions. This provides an abstract representation of the VNF with the ability to support multiple overlay technologies as well as enables automation of software-defined networking (SDN) technologies such as Openflow. With the VNF Forwarding graph you can use all the capabilities of the VNF catalog, to obtain virtual network functions in the form of a graph, and then use it to create VM resources that could be deployed in NSX. The VNF Forwarding Graph (VFG) is a high-level view of virtual network functions.
The VFG helps show how data flows through a set of functions and provides key information such as the total number of packets being processed, the forwarding accuracy, and latency. The VNF Forwarding graph is a device-level graph that represents the initial forwarding table. The VNF Forwarding Graph is stripped after each re-optimization. The VNF Forwarding graph describes how a packet can be delivered to a machine in the Compute Environment. The VNF Forwarding graph is a visual representation of how the data flows through your running application, showing you which parts of your application handle what data. VNF Forwarding Graph is a visual representation of the packet forwarding logic of a specific network function (e.g., load balancing). It describes how packets are forwarded based on the criteria that are set by the user.
A VNF Forwarding graph is a graph that represents the relationships between layers, links, and interfaces (LILs) in order to specify how a VNF forwarding node operates. A VNF Forwarding graph can consist of any number of LILs, where each LIL represents an output port or input port. Each LIL has its own set of properties defined by the definitions document of the underlying technology stack supporting the LIL. A visual tool for understanding and configuring the Forwarding Graph in a VNF (Virtual Network Function). This application helps users to analyze their VNF implementations and track their progress. The Forwarding Graph is a set of forwarding rules that determine the path of packets through the layers in a virtual network function (VNF). This can be used to configure data planes to perform traffic engineering or support different network topologies. It also provides backward compatibility with our existing data plane architecture by enabling customers to migrate their existing VMs into containers running on NVF2.
The VNF Forwarding graph provides a way to describe the flow of traffic through the VNF and virtual network functions, it contains two types of edges: input and output. Input edges represent actions that must be performed on packets before forwarding them to the next hop. Output edges represent actions that will be performed on incoming packets received by the VNF so as to forward them toward their destinations. The VNF Forwarding Graph shows the relationships of VNFs in the platform and it will be a vital part of any installation to understand the topology that is being deployed. The VNF Forwarding Graph is a representation of the forwarding state of a VNF. It allows developers to identify dependencies between portions of the forwarding graph, view the structure of the graph, and understand how such dependencies are affected by any changes they make to their cloud-native applications. The VNF forwarder is a virtualized network function that implements the forwarding plane of the service.
The VNF forwarder accepts packets from external interfaces and forwards them towards their destination. The VNF Forwarding graph is a graphical representation of the logical data plane. It consists of data plane entities (such as distributed forwarding elements) and their connections to form the desired logical data plane, enabled by virtualized resources such as virtual switches. The VNF Forwarding graph shows the topology of virtual network forwarding elements in a virtualized environment. It displays and describes the logical relationships between virtual data centers and their constituent components, such as servers, storage, and gateways.
