Source Routing
overall review score: 3.5
⭐⭐⭐⭐
score is between 0 and 5
Source-routing is a technique in computer networking where the sender of a packet specifies the exact sequence of routers that the packet should traverse on its way to the destination. Unlike typical routing, which relies on intermediate routers to determine the path based on destination and routing tables, source-routing empowers the sender to define the route explicitly, which can be used for traffic engineering, security, or policy enforcement.
Key Features
- Sender-defined routing paths for packets
- Enhanced control over packet traversal
- Can be implemented using explicit routing headers (e.g., IPv6 Routing Header)
- Potential for improved network management and security
- Support for complex routing policies and testing
Pros
- Provides precise control over packet routes, useful for network testing and troubleshooting
- Can enhance security by avoiding malicious or unreliable nodes
- Useful in scenarios requiring strict traffic management or policy enforcement
- Facilitates traffic engineering to optimize network performance
Cons
- Increases complexity in network management and configuration
- Potentially introduces security risks if used maliciously (e.g., route hijacking)
- Not widely supported across all network equipment and protocols
- Can lead to routing loops or inefficiencies if not carefully managed
- May conflict with standard IP forwarding practices, complicating interoperability
