Boost Your SD-WAN Security with Portwell ANS-8A64

SD-WAN and Network Transformation

SD-WAN (Software-Defined Wide Area Network) applies SDN technology to WAN. It connects corporate networks, data centers, Internet applications, and Cloud services, aiming to:

• Reduce WAN operation costs
• Improve connection flexibility

With the growing reliance on Cloud for data processing, enterprises face rising demands for network security, as sensitive information such as personal ID, credit card numbers, and private data must be safeguarded.

Intel Atom^® C3000 Processor Series

The Intel Atom^® C3000 processor series delivers:

• Industry-leading performance per watt
• Low thermal design power (TDP)
• Configurable high-speed I/O

It is an ideal foundation for innovations in networks, storage devices, IoT, and scalable solutions.

Intel^® QuickAssist Technology (Intel^® QAT)

Integrated Intel^® QAT accelerates:

• IPSec operations
• Data encryption / decryption
• Data compression

By offloading these workloads, CPU resources are freed for critical applications, enhancing system performance and efficiency.

IPSec Protocol and Security

IPSec, operating at Layer 3 of the OSI model, supports:

• Host-to-host mode
• Tunnel mode

Both enable secure VPNs (Virtual Private Networks) that strengthen data transmission security.

The Portwell ANS-8A64, powered by Intel Atom^® C3000 and Intel^® QAT, is a reliable network acceleration platform for SD-WAN. In field tests with DPDK and Intel^® QAT, the ANS-8A64 demonstrated remarkable IPSec encryption/decryption performance.

Test Results

One-Way Test

Packets sent unidirectionally from Server Port1 → Port2.
Encryption/decryption handled by IPSec Gateway1 and Gateway2.

• Purple bar = throughput with Intel QAT
• Green bar = throughput with CPU

Two-Way Test

Packets sent simultaneously between Server Port1 ↔ Port2.
Encryption/decryption handled by IPSec Gateway1 and Gateway2.

With Intel^® QAT, throughput improved by up to 3x compared to CPU-only processing.

Conclusion

Both one-way and two-way tests confirm that the Intel^® QAT hardware acceleration engine delivers:

• Significant system optimization
• Up to 3x throughput improvement
• Enhanced network security performance

With Portwell’s expertise in network appliance design, the ANS-8A64 series offers not only Intel^® QAT acceleration, but also scalability, reliability, and flexibility tailored for SD-WAN and security vendors.
