Automate Installation & Easy Deployment

The Asterfusion CX-M switch supports ZTP (Zero Touch Provisioning), which be able to retrieve configuration files from local or remote file servers and then load the configurations into the switches automatically.

ONIE (open network install environment) is also preloaded on the switch.With ONIE, it can automatically install, upgrade and manage different versions of network operating system software. This combination of ZTP and ONIE would allow data center administrators to cut down the OAM workload and hence significantly reduce the overall operational cost.

01 / Ultra Low Latency Cloud Data Center Switch by using Marvell Teralynx

-For latency-sensitive cloud data center applications
Industry-leading low latency switching(~400ns) satisfy the requirements of latency-sensitive application

The Asterfusion CX532P-N offers industry-leading low latency switching capabilities as low as ~400ns in most application scenarios. Allowing it to more than satisfy the requirements of latency-sensitive applications, such as NVME, IoT,VR/AR/MR,high-frequency trading, big data analysis, machine learning and etc.

02 / Asterfusion SONiC NOS Support RDMA over Converged Ethernet (ROCE)

-Zero Packet Loss RoCE provides efficient lossless transport data center network

The Asterfusion CX532P-N supports RoCEv2 which allows remote direct memory access (RDMA) over an Ethernet network. It solves the delay of server-side data processing and frees up the CPU to do more important tasks, such as running applications and processing large amounts of data. It increases bandwidth and reduces latency, jitter, and CPU consumption, helping to build highly efficient and cost-effective data center networks.

03 / Asterfusion SONiC NOS Support In-band Network Telemetry

-For intelligent cloud data center network operations

The Asterfusion CX532P-N switch supports INT(In-band Network Telemetry) which provides accurate and comprehensive real- time network telemetry information including port interfaces, packet latency, packet queue lengths, etc. Cloud data center network administrators can leverage INT information to optimize their business applications and network operations, helping to build efficient, intelligent and highly resilient data center networks.

04 / Asterfusion SONiC NOS Support VXLAN & BGP EVPN

-Implements a layer-2 virtual network structure dynamically
MP-BGP EVPN Technology

EVPN-VXLAN expands the potential number of Layer 2 domains and realizes services such as multi-tenant hosting and virtual machine migration.

05 / Asterfusion SONiC NOS Supports EVPN-Multihoming

AsterNOS 3.1-R0314P06.2, supports EVPN multihoming,adresses several customer challenges. Firstly, EVPN multihoming allows for the connection of a customer site to multiple Provider Edge (PE) devices, ensuring redundancy &high availability through multiple traffic paths. It also facilitates traffic load balancing across multiple PE devices. Moreever, it eliminates the need for complex protocols like STP and VRRP, thereby simplifying network design.

How AsterNOS is differ from SONiC Community ?

Firstly ,AsterNOS is a commercial SONiC NOS compare to native SONiC community, which means for enterprises, AsterNOS it’s ready to use version, especially we have optimized and upgraded network virtualization functions (Overlay Network), such as VXLAN &BGP- EVPN.

What are the feature that your SONiC support?
It built on top of standard Linux systems and with SONiC/SAI as its kernel is characterized by fully open structure, completely decoupled hardware and software, loosely unionized software modules, high reliability architecture, and easy functional expansion. It leverages the latest technologies such as containers and in-memory database.
Does AsterNOS can run on other vendor’s hardware?
Our SONiC based AsterNOS can perfect run on our own hardware, in theory it can run on other vendor’s hardware, there will be a problem on verify the compatibility between our software and other vendor’s hardware,we can arrange a meeting call discuss specially. I strongly suggest you to use our own hardware, which supports the best software compatibility, tech support, hardware stability and of course very good cost.
Is there any license fee or Software support fee that we need to pay for your version of SONiC?
Usually our AsterNOS runs on our own hardware (for Tofino and Teralynx), we provide either bare metal hardware, or hardware with AsterNOS, there is some amount of software cost if you choose H/W and S/W bundle, but this bundle should be more cost effective than today’s White Box from one vendor and NOS from another vendor.
Does AsterNOS Suport Intel,Broadcom?
Our AsterNOS software support intel ,not Broadcom.
What is the difference SONiC and P4, and also tell us the difference of your NOS and those similar.
SONiC is used in most data center fabric as the basic OS, our software work on both innovium and marvell makes SONiC be able to run these switch chips smoothly, which is our value to help people who want to use innovated features on today’s new switch chip other than broadcom.
P4 is another approach for today’s network disaggregation, it has pretty good usability in niche markets like gateway, load balance or NPB, in these market when people also want to be part of cloud eco system, they need a way to combine P4 with SONiC, that’s what we are doing, we help people to implement these applications in SONiC way.
How AsterNOS is differ from other SONiC Software?

AsterNOS work on both Teralynx and Intel Tofino, and Marvell. Making SONiC be able to run these switch chips smoothly, which is our value to help people who want to use innovated features on today’s new switch chip other than broadcom.

Does Asterfusion SONiC NOS support EVPN , Vxlan and MC LAG ?

Yes, AsterNOS fully support EVPN, VXLAN and MC-LAG

Is it easy for us to change and use the functions (Software) provided by Asterfusion, or to add functions related to the packet control and management function (OAM)?
It depends on your application, in general you can easily start from either SDE or SONiC to all the functions about date plane and management plane.
