Tiivistelmä
Ericsson Router 6000 Series is a new high-capacity router series for mobile backhaul network, which is under development currently. The next generation NPU is adopted by the router family products. Recently, a new technology, EVPN has emerged and has been reported to overcome some VPLS limitations. However, a detailed comparison of the EVPN and VPLS technologies has not been systematically done. Also, whether the next generation NPU supports EVPN feature is unknown. The purposes of this work are to compare the VPLS and EVPN technologies in detail, to discover the possibility of implementing EVPN on the next generation NPU, and to provide reliable references for future work.
The comparison is performed from the perspective of address learning, load balancing and services. By using the unified test bed, EVPN prototyping and testing are performed on the NPU, based on a typical EVPN topology and scenario. Ericsson Finland provides most of the resources and facilities for this study.
The results indicate that EVPN is superior to the VPLS technology in several aspects. By applying a combination of control plane and data plane address learning, the multi-homed flow-based load balancing and the integration of L2 and L3 services, the EVPN solution significantly improves the network resiliency and efficiency, compared to VPLS. Therefore, EVPN is strongly recommended on Router 6000 Series. The results also show that it is possible to implement an EVPN feature on the next-generation NPU.
Overall, this study provides pilot research results and valuable references for future implementation work. In the next step, more complicated topologies and scenarios of EVPN could be introduced and tested. Also the current testing environment could be enlarged to adapt to new conditions.
