A Vector Routing Protocol for Computing and Network Convergence in Digital Grid Scenario

In an industrial Internet with clear hierarchical division like China’s digital grid, real-time and fast intelligent decision-making for power production control at the local field level can be supported by cloud-edge computing. In the cloud-edge fusion within this scenario, there will be a large amount of information interaction and data transmission between entities in different locations, which also involves differentiated routing decisions for computing tasks. Therefore, it is of great significance to comprehensively consider the computing resources and network resources in the digital grid to schedule the computing tasks in the above scenario. Distributed routing is a routing method relative to centralized control routing (such as SDN, software-defined network). Each individual distributed router calculates the routing table itself and then determines the forwarding strategy based on the previous calculation results. Such as EIGRP (Enhanced Interior Gateway Routing Protocol), DSDV (Destination Distance Vector Protocol), etc. Based on the distributed vector routing technology, this paper proposes a distributed routing protocol that can comprehensively consider the existing computing resources and network resources (delay, bandwidth, etc.) in the network for calculation, and designs a simulation test system. The system can virtualize a small-scale network including several routing nodes, and complete processes such as neighbor discovery, route notification, route computation, and data forwarding, thereby verifying the availability of routing protocols.
