Asterfusion Data Technologies

Network carriers constantly face bandwidth challenges. The COVID-19 pandemic has significantly increased network traffic over the past three years. For instance, 400G Ethernet has emerged as the top technology since 2020, according to Cloud Service Providers (CSPs) and various network forecast reports. AT&T predicts a five-fold increase in network traffic over the next five years, with users consuming an average of 4.5TB (Terabytes) of data per person. This tremendous growth in traffic is fueled by increasing video streaming, cloud computing, data centers, artificial intelligence (AI), machine learning (ML), and the ever-growing number of IoT devices. In essence, 400G Ethernet will surpass 100G and 200G deployments more rapidly than 100G did for previous Ethernet technologies. What exactly is 400G Ethernet? 400G Ethernet, or 400 Gigabit Ethernet, represents the latest generation of cloud infrastructure and is four times faster than its predecessor, the 100G standard. Also known as ...

With the scale development and industry application of cloud computing, VR/AR, automatic driving, artificial intelligence, etc., while improving people's life and enhancing the innovation ability of enterprises, the bandwidth requirement for data centers has increased by more than 50% annually, and in addition, cloud computing has fundamentally changed the computing model and traffic model, and the network flow direction has changed from the traditional north-south traffic to the horizontal traffic between IDCs and IDCs, or between resource pools. The proportion of horizontal traffic between data centers is gradually increasing, which requires that data center interconnection network must have greater bandwidth capacity, and 400GE becomes the primary focus of data center construction. Join us today as we explore the ins and outs of Asterfusion’s remarkable 32x400G switch   CX732Q-N   through a detailed teardown.  Boasting a sleek design coupled with high performance, the ...

  Previously, we’ve written a lot articles about open networking and white box switching. From now on, we will start to do a series of Asterfusion switch teardowns for a more detailed evaluation. Before the text begins, it is necessary to give a brief introduction to the Asterfusion switch family, which is divided into DC Fabric and Campus Access . The former provides TOR and SPINE application networking for data centers, and the latter offers typical networking capabilities for campus access.  Asterfusion named its SONiC-based enterprise distribution as  AsterNOS , and the system model equipped with AsterNOS was named  CX series.  Among them,  CX200-M  is a new generation Campus Access series, the speed starts from Gigabit access; that is part of the Asterfusion’s campus network solution for aggregation and access layers. But actually, the solution is based on  Spine/Leaf architecture , not the traditional “access-aggregation-core”, which we...

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, ...

  In the mobile office era, WiFi roaming has become a daily routine, but from time to time we encounter situations where the network is disconnected and the business is interrupted, and we even need to re-do cumbersome security authentication for this. This is often because the IP subnet we belong to has changed during the move, and the terminal has to obtain a new IP address to adapt to the new gateway. To improve user experience and realize seamless roaming of campus wireless networks, there are two common solutions in the market: 1. Plan the area that needs to roam in a Layer 2 network, but the larger the Layer 2 network, the less secure it is; 2. A tunnel is established between the old and new gateways, and the roamed terminal traffic is transmitted to the original gateway through the centralized gateway controller for forwarding, which in turn leads to complex configuration and inefficient traffic forwarding paths, which affects roaming performance. Asterfusion cloud-based cam...

 The conversation about the new architecture of data center networks is heating up as software-defined networks (SDN) and open networks continue to gain popularity. The main focus now is on where the new data center network gateway should be deployed.  Currently, distributed gateways are more widely used in data centers due to their adaptability to network isolation and management in a variety of scenarios, including multi-tenancy, virtualization, and cloud computing. This enhances network flexibility and reliability. Additionally, SDN technology enables distributed gateways to perform functions like dynamic service links, traffic scheduling, and load balancing. However, centralized gateway designs, such as using the traditional three-tier architecture design, are still common in some more traditional data centers. The upside of using centralized gateways is that they are easy to deploy, can handle large amounts of traffic, and are easy to manage and maintain. For more: https:...
