What is the Difference Between In-Switch Routing and Centralized Routing?
🆚 Go to Comparative Table 🆚In-Switch Routing and Centralized Routing are two routing methods used in network platforms in the telecommunication industry. Here are the main differences between them:
- Service Provisioning: In Centralized Routing, service provisioning is centralized, whereas in In-Switch Routing, it is distributed.
- Database Method: Centralized Routing uses a vendor-independent database method with a common interface for all switches. In contrast, In-Switch Routing has a distributed database, and each switch may have its own limitations that need to be managed.
- Real-time Traffic Management System and Routing Decision Making System: In Centralized Routing, these systems can feed the Least Cost Routing (LCR) or Best routes to the centralized database with a single interface. In In-Switch Routing, LCR or routing decisions need to be loaded onto each switch via different interfaces and formats, depending on the switch's limitations.
- Database Availability: In Centralized Routing, the database availability is more important since the whole network relies on a single point. Failures can affect the entire network. In In-Switch Routing, the database is independent of the network, and in case of failures, only the affected switch is impacted.
- Redundancy: In Centralized Routing, the master database can be replicated across multiple boxes as required and kept in active sync with the master. In In-Switch Routing, there is no built-in redundancy.
In summary, Centralized Routing relies on a single, centralized database for routing decisions, while In-Switch Routing distributes the routing decisions to each switch. This results in key differences in service provisioning, database management, and redundancy.
Comparative Table: In-Switch Routing vs Centralized Routing
In-switch routing and centralized routing are two different methods used in network platforms within the telecommunication industry. Here is a table comparing the differences between the two:
Feature | In-Switch Routing | Centralized Routing |
---|---|---|
Routing Database | Each switch maintains its own routing database, which can lead to duplication and increased manpower requirements. | The routing database is kept in a central place, and each switching element communicates with the centralized routing database. |
Communication Protocols | Switching elements may use various protocols, such as AIN, INAP, MAP, ENUM, SIP, and WIN, to communicate with the centralized routing database. | Switching elements use the same protocols to communicate with the centralized routing database. |
Database Availability | The availability of the database is more important in centralized routing, as the entire network relies on a single point. | Database availability is less critical in in-switch routing, as the database is independent of the network and failures affect only the specific switch. |
Technical Expertise | Technical expertise or vendor experience is not required to load data in centralized routing. | Technical expertise or vendor experience may be required to load data in in-switch routing. |
Service Provisioning | Service provisioning is centralized in centralized routing. | Service provisioning is not centralized in in-switch routing. |
Database Limitations | In in-switch routing, switches may have database limitations that need to be managed. | There are no database limitations in centralized routing, as the database is managed centrally. |
Real-time Traffic Management | Real-time traffic management can be more challenging in in-switch routing due to the distributed nature of the routing databases. | Real-time traffic management is more straightforward in centralized routing, as all switching elements communicate with a single, centralized routing database. |
In summary, centralized routing offers better scalability, manageability, and real-time traffic management compared to in-switch routing. However, the choice between the two methods depends on the specific requirements and constraints of the network.
