PublishTime： 2024-09-16 Article Source：usr Official Website

Dynamic routing protocols build and maintain routing tables in the network through automatic learning and updating of routing information, in order to achieve optimal path transmission of data packets. Compared with static routing, dynamic routing protocols can automatically adapt to changes in network topology, reduce the workload of network administrators, and improve the flexibility and reliability of the network. In the field of industrial Internet of Things, due to the large number of devices and complex network structure, the application of dynamic routing protocols is particularly critical.

1、Main Classification of Dynamic Routing Protocols

1.1 Classification By Scope of Actioninterior Gateway Protocol (Igp)

The Interior Gateway Protocol is a routing protocol that operates within an Autonomous System (AS). An autonomous system is a network of routers that run the same routing protocol and are governed by a single authority. Common IGP protocols include:

RIP Routing Information Protocol: An interior gateway protocol based on distance vectors, suitable for small to medium-sized networks. It transmits routing information through the UDP protocol and periodically sends the entire routing table to neighboring routers.

OSPF Open Shortest Path First: An interior gateway protocol based on link state, suitable for large networks. OSPF constructs the network topology by collecting link state information and calculates the shortest path accordingly.

IS-IS Intermediate System to Intermediate System: a routing protocol for the OSI network layer that also uses a link state algorithm. IS-IS was originally designed for ISO's CLNP Connectionless Network Protocol, but was later extended to support IP networks.

Exterior Gateway Protocol, EGP
The external gateway protocol is used to exchange routing information between different autonomous systems. Currently, the most commonly used EGP is BGP Border Gateway Protocol, which supports complex routing strategies such as route aggregation and AS path attributes to ensure the reliability and efficiency of routing between autonomous systems.

1.2 Classification by Destination Address Typeunicast Routing Protocol

Unicast routing protocols are used to generate and maintain unicast routing tables, which are routing tables that only target a single destination address. Common unicast routing protocols include RIP, OSPF, BGP, and IS-IS. When transmitting data packets in the network, these protocols use point-to-point communication methods.

Multicast routing protocol
Multicast routing protocols are used to generate and maintain multicast routing tables, supporting the simultaneous transmission of data packets from the source node to multiple destination nodes. Common multicast routing protocols include DVMRPDistance Vector Multicast Routing Protocol, PIM-SMProtocol Independent Multicast-Sparse Mode, and PIM-DMProtocol Independent Multicast-Dense Mode. Multicast routing protocols play an important role in application scenarios such as video conferencing and real-time data transmission.

1.3 Classification by algorithm used Distance Vector Routing Protocol

Distance vector routing protocols construct routing tables by exchanging routing information between neighboring routers. Each router updates its routing table based on the received routing information and selects the shortest path to each destination. Common distance vector routing protocols include RIP and BGP. Although BGP is more complex in terms of functionality, it still retains the characteristics of distance vectors in some aspects.

Link-State Routing Protocol

Link state routing protocols construct a network topology by collecting link state information from all routers in the network, and calculate the shortest path accordingly. Unlike distance vector routing protocols, link state routing protocols do not require the periodic exchange of the entire routing table, but only exchange link state information. Common link state routing protocols include OSPF and IS-IS.

2、Advantages And Challenges of Dynamic Routing Protocols

2.1 Advantage
Automatically adapting to network changes:Dynamic routing protocols can automatically detect and respond to changes in network topology without manual intervention.

Optimized routing:By calculating the shortest path or optimal path, dynamic routing protocols can improve the efficiency of data transmission.

Support for large-scale networks:For large and complex industrial IoT networks, dynamic routing protocols can provide more efficient and reliable routing services.

2.2 Challenge
Network bandwidth usage:Dynamic routing protocols require regular exchange of routing information, which may consume a certain amount of network bandwidth.

Convergence time:When the network topology changes, dynamic routing protocols require a certain amount of time to converge to a stable state.

Configuration complexity:Compared with static routing, the configuration of dynamic routing protocols is more complex and requires network administrators to have higher professional skills.

The dynamic routing protocol in Industrial Wireless Router is one of the key technologies for achieving efficient, stable, and scalable industrial IoT. By reasonably selecting and configuring dynamic routing protocols, network performance can be optimized, data transmission efficiency can be improved, and network management costs can be reduced. However, in practical applications, factors such as network bandwidth, convergence time, and configuration complexity need to be fully considered to ensure the stability and reliability of the network.
