研究目的
To examine Software Defined Wide Area Network (SD-WAN) solution, its architecture, and benefits of use by comparing two scenarios: Policy-based routing on WAN links in classical IP/MPLS network and using SDN controller to manage traffic on WAN links.
研究成果
The study demonstrates the benefits of using SD-WAN over classical IP/MPLS networks, including dynamic traffic management based on link conditions, global network visibility, and automated policy enforcement. SD-WAN provides a flexible, cost-effective solution for modern network requirements.
研究不足
The study is limited by the use of virtual routers in a simulated environment, which may not fully replicate the complexities and variabilities of real-world network conditions.
1：Experimental Design and Method Selection:
The study compares two scenarios for routing and traffic management in WANs: classical IP/MPLS network with policy-based routing and SD-WAN using an SDN controller.
2：Sample Selection and Data Sources:
The experiments are conducted on a topology containing six routers connected with eight links, implemented on virtual routers in Cisco’s Cloud virtual environment.
3：List of Experimental Equipment and Materials:
Cisco ASR 9000 series routers with IOS XR, OpenDayLight (ODL) controller, Ubuntu virtual machine.
4：Experimental Procedures and Operational Workflow:
Configuration of routing policies and TE attributes in both scenarios, establishment of PCEP sessions between routers and ODL controller, and analysis of routing paths.
5：Data Analysis Methods:
Analysis of MPLS forwarding tables and routing paths based on configured policies and link conditions.
