Description: The VNF Forwarding Graph (Virtual Network Function Forwarding Graph) is a visual representation that illustrates the data flow between different Virtual Network Functions (VNFs) within a network architecture. This graph is fundamental in the context of Software-Defined Networking (SDN) and Network Function Virtualization (NFV), as it allows network operators to understand how various virtualized functions interconnect and communicate. Each node in the graph represents a specific VNF, while the connections between them indicate the path that data takes through the network. This representation not only facilitates the planning and design of more efficient networks but also aids in the management and optimization of the performance of network functions. Furthermore, the VNF Forwarding Graph is essential for implementing quality of service (QoS) policies and ensuring that data flows appropriately and securely through the network infrastructure. In summary, this graph is a key tool for visualizing and managing the inherent complexity of modern networks, where multiple virtualized functions must work together to provide effective and reliable network services.
