 Hi folks, good to see you and let's get started with our presentation and We are from dark cloud companies located in Shanghai, China and I'm we so Senior tech lead in from dark cloud and this is my co-worker. Hi everyone. I'm June I'm the director of global ecosystem development of dark cloud. Yeah wait today we will we are going to Pre-land to cloud native networking for a ice Johnson thing I for Rdmi, so let's get started In the AI world their best practice for model chaining inference fine-tuning has been Implemented by the Kubernetes platform and the cluster is to manage your thousands of GPU hundreds of gigabytes of network and It does not yet satisfied satisfy us with training period. It's very important to guarantee efficient network transmission as we know Rdmi network is already the most common choice and If we are ready if you are rich you can use more advanced only link network, right? so in the Kubernetes Rdmi is mainly implemented by virtual now interface such as make a villain ice IP villain and SOV a typical open source project named Network operator Provided by NVIDIA is a good implementation of the virtual now in the network interface Like make a villain as SOV IP villain However in reality some requirements are still not met We may have to use do thing I for example taking use use of Calico and the network operator at the same time to meet the kinds of network meet needs Secondly with the Administrator has to manager a lot of different sets and the department's Certainly the Macavilla interface Cannot access class IP Finally, it's IPM is not stable enough for production usage Therefore where it could we make make a villain powerful enough to own more features like Calico We may expect it to be all in one We developed developed the and open source project called a spider portal to implement all in one solution as the things have sandbox projects spider port is an Underly and the Rdmi network solution of the Kubernetes it could run on any environments such as the better mental virtual machine and the public cloud on the one hand it almost Implements seeing our futures what Calico does and On the other hand it can bear implement the secondary network card to cooperate cooperate the ways Calico, Celium and the Kube words Spider-Pool offers rich IPan futures as a list in the slide Most importantly, it's reliable and the first the IPv4 Adjustes in the underline network are limited We conducted an extreme test will amount of IP addresses are seen as porous It created 1000 the ports at the same time and the calculated how long all ports get to be running this test that helped us improve the efficiency and the stability of IPan and I show in the figure the report covers spider-Pool where about cool will win Calico and Celium spider-Pool perform the best and Unfortunately, we're about used up by network operator filled at a test Spider-Pool enhances the network accessibility for Mac VLAN IP VLAN and SLV or firstly it offers connectivity between the port and the local nodes which guarantee porous lever needs check even if the Port and the local host are not in the same subnet subnet Secondly spider-Pool helps improve the ability to access class IP only one hand traffic for class IP can be Directly forwarded to a local host and the denet denet by Cropoxy On all hand it introduces the group of EPPI from Celium to Reload the class IP in the porous network in the namespace this directly forwards traffic by underline network interface and the it provides better improvement performance compared to Cropoxy manner up to 25 percent improvement in the latency and up to a 15% improvement in throughput Or certainly when initializing the network namespace of the port spider-Pool helps detect IP conflict and the gateway reachability Spider-Pool supports two scenarios of multiple interface for for parts the first scenario when installing multiple Mac VLAN interface into port it could specify separate IP address for each interface and the policy routes will be automatically adjusted for all interfaces to in order to guarantee the consistent the data path for request and the reply packets avoiding package loss in a secondary scenario When inserting one cataclysm or Celium interface and several Mac VLAN interfaces into port same thing will be automatically done In this table it adjusts a comparison between spider-Pool and the network operator Which indicates the spider-Pool make Mac VLAN things to to be the equivalent of powerful thing I like a cataclysm and the Celium So it's my co-worker's turn Hello Now I will introduce the spider-Pool's community and the partners Spider-Pool is dedicated to build a wilder community ecosystem Since April 2022 the project has released 56 releases at the present half of the contributors have come from non-Docloud company Spider-Pool community has co-operated with several famous companies including Vivo a large mobile firm manufacturer in China and China Mobile one of the biggest Chinese telecom company Spider-Pool was very actively promoted in various channels just like Kupacon, KCD, WAIC and Spider-Pool actively collects proposals from our community partners for instance It's necessary to extend the scheduling feature for AI jobs to improve the network throughput According to the network topology, which could further reduce the AI training period For example, it needs to manage network bandwidth and the network policy for RDMA These proposals will be included in the low map Spider-Pool is well Persistently place great importance on the community proposals Okay, that's everything and appreciate. Thank you. Thank you guys
