#7thingsWeLearntAboutSegmentRouting
Segments Routing is essentially a source routing technique that expresses scalability and simplicity of traffic engineering across multiple Network Domains.
- SR Path, SR Domain, and SR Segment are the main core fundamentals of deploying segment routing in a network.
- The fundamental benefit of SR’s is its ability to simplify the network and minimize resource utilization. This makes it easier to administer and run your network.
- Segment Routing simplifies network architecture by reducing the need for complex protocols and state information in the network nodes. It also improves scalability by minimizing the amount of state information that needs to be maintained in the network.
- To achieve an efficient packet forwarding, MPLS and SR MPLS is Key technologies.
- Traditional routing protocols, like (ISIS/OSPF or BGP serve as the underlying protocols used in SR by the router to build Routing Segments and routing domains.
- A very dominant difference between MPLS and SR-MPLs is that while the former uses a protocol called RSVP-TE to manage traffic, the latter uses the Segment routing protocol to dynamically route traffic to meet the traffic engineering requirements.
- Segment Routing thrives in a very largescale service provider networks environment which requires efficient traffic engineering.
