Study Notes
Routing and Addressing in Computer Networks
- Structured addressing (routing) is more effective than unstructured addressing (bridging) in large networks
- Routing is the dominant form of addressing on the Internet, while bridging is widely used in local area networks
- Delivery schemes in routing include unicast (one-to-one), broadcast (one-to-all), multicast (one-to-many), and anycast (one-to-one-of-many)
- Unicast is the dominant form of message delivery on the Internet, and the article focuses on unicast routing algorithms
- Dynamic routing automatically constructs routing tables based on routing protocols and dominates the Internet
- Examples of dynamic-routing protocols and algorithms include RIP, OSPF, and EIGRP
- Distance vector algorithms use the Bellman-Ford algorithm and assign a cost number to each link between nodes
- Nodes send information to each other to determine the lowest total cost path to each destination
- Link-state algorithms use a graphical map of the network and independently determine the least-cost path to every other node
- The Optimized Link State Routing Protocol (OLSR) is a proactive link-state routing algorithm optimized for mobile ad hoc networks
- Distance vector and link-state routing are intra-domain routing protocols, while path-vector routing is used for inter-domain routing
- Distance vector routing is subject to instability with more hops, while link-state routing requires significant resources and creates heavy traffic due to flooding
