Asterfusion Data Technologies

Asterfusion has had great communication with its customers and has noticed their strong demand for EVPN mutihoming in their network overlay solution. While developing the overlay network has been a priority, open-source solutions have been delayed. Unfortunately, virtualization in the SONiC community has also been slower than expected despite the increasing demand. Even other white box manufacturers rarely support this feature. However, in Q2, Asterfusion SONiC Enterprise distribution - AsterNOS 3.1-R0314P06.2 version already supports EVPN mutihoming, which has enabled this function to successfully run on the data center switch of our CX-N. Today we'll show you how crucial this function is in the data center.  What is  EVPN Multi-Homing EVPN Multi-Homing is a technology that leverages multiple physical links and IP addresses to achieve redundancy and load balancing in a data center network built using Ethernet VPN (EVPN) technology. With EVPN Multi-Homing, each user can connec...

Regardless of whether it's a conventional data center or a modern cloud-based data center, the universal necessity is high availability, and a prevalent issue is the potential single point of failure within the network. In traditional physical networking, to establish highly dependable connections between various devices, LAG (Link Aggregation) technology was developed to ensure high availability of links between servers and switches or even between multiple switches. However, LAG technology possesses its own flaws and is unable to eliminate the risk of equipment failure entirely. Thus, a more advanced technology is required to broaden the original one-to-one connection between devices into a one-to-many connection while ensuring multi-device redundancy and multi-link redundancy. It must also guarantee that devices are able to interconnect with optimal robustness. Introducing MC-LAG, an enhancement of the traditional LAG technology. To accurately comprehend the workings of MC-LAG, ...
