Shide Technology and Intel have jointly completed the new performance test of 21 million load balancing single node connections

Recently, DeTec and Intel jointly completed the new performance test of 21 million connections of single node load balancing products. Intel provides a four tiered load balancing scheme HDSLB (high-density scalable load balancer) optimized by combining hardware and software. A single node has extremely high concurrent connection density, forwarding and TCP connection creation rate, and its performance can be linearly expanded with the number of CPU cores.

Whether it is the AI deep learning model in full swing, the VR&AR and more and more abundant IOT terminal equipment in the ascendant, or the Internet applications that have changed people's lifestyle, such as the very mature multimedia live broadcast, short video, etc., the data streams of various applications will eventually be sent to the cloud server for processing through the network transmission. As a key infrastructure, load balancing products deliver application traffic to multiple servers on average to improve business response speed and availability. All kinds of emerging applications put forward higher and faster scalability requirements for load balancing in terms of data volume and real-time performance. How to ensure the performance, delay and scalability of load balancing from the perspective of testing also poses new challenges.

It is a software and hardware application load test solution (CloudStorm+IxLoad) of DeTec, which has the characteristics of ultra-high performance, true business simulation, and extremely strong stability. The KeysCloudStorm platform of Sinotec is the industry's highest newly built platform. The stand-alone subrack supports up to 54M application layer connections per second (CPS) through modular expansion. CloudStorm platform has two QSFP28 100GE ports, adopts an innovative architecture, allows complex application simulation and a large amount of DDoS traffic, and a single board card can achieve 200Gbps mixed throughput.

Connections per second (CPS) is a key performance indicator of load balancing equipment. This indicator is of great significance in the real world. It describes the ability of load balancing to stably handle TCP connection establishment every second. In the test, each connection requests a 1-byte page, sends a GET request, responds to a GET request, and waves four times to simulate the complete TCP and HTTP life cycle. The test topology is shown in the following figure:

It can be seen from the test results that HDSLB can create a new CPS for TCP connection on the third-generation Intel Xeon processor platform up to 21.8M, and CPS can grow linearly with the number of CPU cores.

Xiu Xiangpeng, General Manager of the Network Application and Security Business Department in Greater China, said, "It will be Deutsch's IxLoad Software It is combined with the high-performance CloudStorm test platform to create an accurate and repeatable test environment, which fully verifies that Intel HDSLB has linear scalability and the highest CPS processing capacity in the industry. "

Bob Ghaffari, Vice President of Intel and General Manager of Enterprise and Cloud Network Business Unit, said: "High density Scalable Load Balancer (HDSLB) is a four layer load balancer based on the collaborative optimization of Intel's software and hardware. Its goal is to achieve industry-leading performance. Through joint testing with TechTec, its advantages have been proved."
