OVS-DPDK Network Architecture Enhancements

ZStack Cloud 5.3.28 introduces the following enhancements to the OVS-DPDK network architecture.

OVS-DPDK Network Now Supports QoS, DHCP, and Security Group Services

Starting from ZStack Cloud 5.3.28, OVS-DPDK network architecture supports network services such as QoS, DHCP, and security group.
  • QoS: Supports bandwidth threshold configuration for flat network NICs, allowing flexible bandwidth allocation based on business requirements to prevent network congestion and ensure smooth operation of critical services.
  • DHCP: Supports DHCP service configuration to automatically assign IP addresses to VMs, significantly improving network deployment efficiency.
  • Security Group: Implements inbound and outbound access control policies for NICs to allow or deny specific traffic, further enhancing network security.

OVS Bond Mode Optimization

ZStack Cloud 5.3.28 optimizes OVS bond mode, now supporting the following three types: Active-Backup, Balance-SLB, and Balance-TCP.


New SDN Network Plus License

ZStack Cloud 5.3.28 introduces the SDN plus license. This license authorizes hardware SDN network integration and advanced network service management capabilities based on OVS-DPDK software networks.

The following features require a SDN network license:
  • Add hardware SDN controllers
  • Create HardwareVxlanNetworks
  • Create hardware SDN-type VXLAN Pools

Introduces Load Balancer Advanced Monitoring

ZStack Cloud 5.3.28 introduces advanced monitoring for load balancers. Add an advanced monitoring server and enable Advanced Monitoring on the load balancer's details page, you can view comprehensive and intuitive monitoring charts.

Currently, you can view advanced monitoring for HTTP and TCP listeners of load balancers.

Supports Rich Monitoring Metrics with Multi-Dimensional Filtering

The Advanced Monitoring page displays key performance indicators of a load balancer through intuitive line charts, including inbound/outbound traffic, active connections, and concurrent connections, and supports filtering based on time span, client IP, frontend IP, and backend server IP for quick data location. This enables O&M personnel to gain deep insights into the load balancer's performance, promptly identify anomalies, and proactively address potential risks.

Supports Detailed and Visualized Connection Statistics

The Advanced Monitoring page provides a detailed visualization of connection statistics for a load balancer in a structured list format, including access time, listener, client IP, front IP, backend server IP, status code, inbound traffic volume, outbound traffic volume, active connections, and concurrent connections. By presenting data visually, the page enhances O&M convenience and assists O&M personnel in tracing traffic sources, identifying abnormal traffic, and ensuring business stability.
