1. Smart IP (Smart Internet Protocol)
Smart IP typically refers to the intelligent management of IP address allocation and routing to optimize network traffic and enhance performance. It can involve automatic configuration and optimization based on network conditions.
Example:
Let’s assume a company has multiple branch offices, and each one needs to route traffic efficiently. The network uses a smart IP system that dynamically adjusts the routing based on network congestion, data priority, and real-time traffic analysis.

Branch 1 (NY Office)
-
Branch 2 (LA Office)
-
Branch 3 (London Office)
2. L3VPN (Layer 3 Virtual Private Network)
L3VPNs provide virtual private network services at Layer 3 (the network layer) of the OSI model. It allows multiple sites to connect securely across a public or private IP network, essentially creating a “virtual” routing environment between locations.
Example:
A company needs to connect multiple branches across different cities and ensure secure, isolated communication between them. L3VPN allows different locations to share a common infrastructure while keeping their traffic separated.

L3VPN Provider: CarrierCo
The two customer networks are interconnected over a public carrier infrastructure using L3VPN. The provider (CarrierCo) uses MPLS or similar technologies to ensure data security and isolation between the two customer networks, even though they share the same physical infrastructure.
Example Configuration for an L3VPN:
Key Benefits:
-
Privacy: Traffic is logically separated between customers, even if they share the same physical infrastructure.
-
Security: Encrypted tunnels ensure that data is secure across the public network.
-
Scalability: L3VPN can support multiple customers, which can scale easily without affecting the performance of other customers.
