Download this case study PDF format

Overview

The bike, a global technology company acting on a wide range of platforms around the world in a large extent, facing significant challenges to ensure data centers. With over a million servers running applications used, the company requires a networking solution that can handle high passes while continuing strength. By wasting EBPF technology, bytedance has successfully implemented a decentralized networking solution that improves efficiency, scalability, and performance.

CHALLENGES

Like the launch of this bike, the existing solution to the internal networking, which depends on the virtual Ethernet devices, began to show limits. Including primary problems:

• Botters to take care: Virtual Ethernet-based solutions to distributed soft bottlenecks in the network stack, which causes disabilities.
• Safety concerns: Insuring stability such a large scale is critical, but unreliable solutions risk in production environments.
• Kernel Version Constraints: Upgrade to the required version of the kernel (6.8) cannot be immediately due to surgical restrictions.

To answer these challenges, byeddance requires a strong solution, and high-performance solutions that can be deployed in additional data centers.

ANSWERS

The bike has been made by EBPF to meet these challenges. Ebpf, a powerful technology for the dynamic manamic and secure Linux kernel, enables the company to refesign the networking content. The key steps to enforcement are included:

• Identification of netkit:
  • Earn buteddance KetcoA device led by ebpf
  • In order to accommodate the existing constraints and deployment of the heritage, netkit is backported to the Kernel Version 5.15, ensuring the adaptability of bydedance infrastructure.
• Upgrade strategy upgrade:
  • A carefully orchant upgrade upgrade ensures a slight destruction. Both the upgrades in the inner range and hire kernel in the kernel are handled independently, allowing a gradual shift to netkit.
  • There is a concern with the potential issues of deployment mixture, so the incorporation between Netkit and Virtual Ethernet is secured by the full transfer.
• Handling Failures:
  • Falling mechanisms are implemented to handle scenarios where Netkit or fellow EBPF programs failed, to ensure uninterrupted service.

result

Ebpf deployment and Netkit has provided significant progress in bydedance data centers:

• The performance acquisitions:
  • Eliminated the last soft soft on the network stack, which leads a 10% progress forever.
  • Solved issues with high CPU load and packet reorering caused by virtual ethernet, developing overall efficiency.
• Scoast and stability:
  • Successfully sent Netkit to many clusters, showing reliability and readiness to wider adoption.
• Operation Benefits:
  • Simplified networking stack, which reduces safety on top and repair system repair.

Future plan

Plans to dropped planning further exploration of EBPF potential, including:

• Offloading hardware: Ebpf integration with hardware offloading in order to achieve a better network performance.
• Wider cases of use: Expand ebpf application beyond networking within other systems optimization areas.

Finally

The adoption of Ebpf and Netkit promotes the changing potential of this technology to solve a large network’s challenging network. By refreshing its networking stack and wasting flexibility to the ebpf, bydance reaches performance improvements while ensuring strength and generally. This deployment serves as a sense of EBPF capability to withdraw change in modern data center operations.
