현대의 IT 환경에서 네트워크 인터페이스 카드(NIC)는 시스템의 성능과 효율성을 좌우하는 중요한 역할을 합니다. 그중에서도 SmarNIC(Smart Network Interface Card)과 SuperNIC(Super Network Interface Card)는 각각 독특한 강점과 특징을 가진 NIC 기술로 주목받고 있습니다. 이번 블로그 글에서는 SmarNIC과 SuperNIC의 특징과 장점을 살펴보고, 두 기술을 비교하여 어떤 환경에서 더 적합한 선택인지를 알아보겠습니다.
SmarNIC: 네트워크 효율성과 관리에 집중하다
SmarNIC은 데이터 패킷의 관리와 라우팅을 최적화하여 네트워크 작업의 효율을 극대화할 수 있도록 설계된 NIC입니다. 특히 고성능 애플리케이션의 안정성을 지원하는 QoS(Quality of Service)를 제공하며, 가상화 환경에서도 뛰어난 성능을 발휘합니다. 클라우드 기반 시스템을 사용하는 환경에서 매우 유용하게 활용될 수 있습니다.
SmarNIC의 가장 큰 장점은 네트워크 작업의 부하를 분산시키는 데 있습니다. 서버 CPU의 부담을 줄이고 시스템 전반의 성능을 향상시킴으로써 네트워크 병목 현상을 최소화합니다. 또한 안정적이고 빠른 데이터 전송을 실현하여 대규모 데이터 센터와 가상화 환경에서 매우 효율적으로 작동합니다.
하지만 초기 도입 비용이 비교적 높을 수 있으며, 특정 소프트웨어와의 호환성 문제가 발생할 가능성이 있다는 점은 고려해야 할 사항입니다.
SuperNIC: 초고속 데이터 처리의 중심
SuperNIC은 초고속 데이터 전송과 대용량 데이터 처리를 지원하는 NIC로, 빅데이터 분석 및 고성능 컴퓨팅 환경에서 탁월한 성능을 발휘합니다. 네트워크 연결의 초저지연(low latency)을 제공하며 대규모 작업에서도 안정성과 속도를 극대화할 수 있도록 설계되었습니다.
SuperNIC은 대량 데이터를 신속하고 효과적으로 처리하며, 이를 통해 복잡한 데이터 분석과 처리가 원활하게 이루어질 수 있습니다. 또한 빅데이터 환경과 초고속 컴퓨팅 작업에서 빠르고 안정적인 연결을 제공하여 대규모 프로젝트에서도 높은 신뢰성을 유지합니다.
그러나 높은 전력 소모와 하드웨어 요구 사양으로 인해 초기 설치 비용이 증가할 가능성이 있으며, 전력 효율성을 중요시하는 환경에서는 제한적으로 사용될 수 있습니다.

SOLUTION DESCRIPTION
Scaling TRex Traffic Generation Performance
Napatech Link™ Capture Software
Testing and validating network performance is of the utmost importance to network equipment manufacturers, operators and owners. In the past, the traditional approach to testing network performance was based on proprietary traffic generators. But while such solutions have indeed proved efficient for a long series of use cases, they either fall short or prove massively cost prohibitive when it comes to complex and realistic traffic generation.
To manage the cumulating density of functionalities and workloads, the industry now demands a testing regime that not only delivers outstanding performance – but also offers better scalability and drastic cost improvements.
TRex
TRex is an open source traffic generator developed specifically to address these shortcomings through an innovative and extendable software implementation. What differentiates TRex is its portability, cost, capacity and flexibility.
As for any other traffic generation solution, the ability for TRex to reliably generate packets at line rate across all packet sizes is paramount. Whether simply packet blasting or replaying PCAP files for testing, the ability to send traffic for small packets at the maximum speed is a prerequisite.
Traffic reception is also of critical importance. The ability to receive the generated traffic once it has traversed the Device Under Test (DUT) is the only way of measuring the effectiveness of the solution. If the traffic reception does not match the generation capabilities, testing is compromised as one cannot identify if it is the DUT that is dropping traffic or the test equipment itself.
Accelerated TRex performance
In addressing this challenge, Napatech has created a hardware acceleration solution, based on the Napatech Link™ Capture Software, that alleviates the load on the CPU and thereby greatly increases TRex performance.
Optimized for lossless transmit and receive, the solution demonstrates substantial performance advantages for TRex compared to a standard Network Interface Card (NIC):
• Up to 4x transmit performance improvement • Up to 16x receive performance improvement
Turning acceleration into value These performance advantages ultimately allow you to:
• Maximize your server performance by improving CPU utilization
• Minimize your TCO by reducing number of servers, thus optimizing rack space, power, cooling and operational expenses
• Diminish your time-to-resolution, thereby enabling greatly increased efficiency
TRex generates layer 4-7 traffic based on pre-processing and smart replay of real traffic templates. TRex amplifies both client and server-side traffic. When running on the Napatech SmartNIC with Link™ Capture Software, TRex can both generate and receive traffic at 2x40G line rate regardless of packet size. This enables scalability both of bandwidth and feature complexities, thus providing businesses a highperformance and massively cost-efficient alternative to proprietary traffic generators.
TRex Stateless functionality includes support for multiple streams, the ability to change any packet field and provides per stream statistics, latency and jitter. Advanced Stateful functionality includes support for emulating L7 traffic with fully-featured scalable TCP layer.
Test configuration
The outstanding improvements achieved with this solution were demonstrated by comparing TRex performance running on a Dell PowerEdge R740 with a standard 40G NIC card and the Napatech NT200 SmartNIC.
Key solution features
• Line rate network throughput for all packet sizes
• Lossless capture for perfect inspection and detection
• Onboard packet buffering during micro-burst or PCI Express bus congestion scenarios
• Advanced host memory buffer management for ultra-high CPU cache performance
• Packet classification, match/action filtering and zero-copy forwarding
• Intelligent and flexible load distribution to as many as 64 queues improving CPU cache performance by always delivering the same flows to the same cores
Napatech Link™ Capture Software
The stunning benchmarks for TRex were achieved by deploying Napatech’s Reconfigurable Computing Platform™, based on FPGA-based Link™ Capture Software and Napatech SmartNIC hardware.
Napatech’s Reconfigurable Computing Platform flexibly offloads, accelerates and secures open, standard, high-volume and low-cost server platforms allowing them to meet the performance requirements for networking, communications and cybersecurity applications.
TRex
TRex is an ideal example of the type of critical enterprise security application that can achieve better performance through hardware acceleration.
TRex is an open source, low cost, stateful and stateless traffic generator. Typical use cases include:
• Creating high scale benchmarks for stateful networking gear, e.g. firewalls, DPI, IPS and load balancers
• Simulating high scale DDOS attacks
• Performing high scale, flexible testing for switches
• Performing scale tests for huge numbers of clients/ servers for controller-based testing
• Performing EDVT and production tests

TRex
TRex is an ideal example of the type of critical enterprise security application that can achieve better performance through hardware acceleration with the Intel PAC and Napatech dataplane software.
TRex is an open source, low cost, stateful and stateless traffic generator. Typical use cases include:
• Creating high scale benchmarks for stateful networking gear, e.g. firewalls, DPI, IPS and load balancers • Simulating high scale DDOS attacks • Performing high scale, flexible testing for switches • Performing scale tests for huge numbers of clients/ servers for controller-based testing • Performing EDVT and production tests
TRex can be compiled with native support for hardware acceleration based on the Intel hardware and Napatech software. Instructions specific to building TRex with support for Napatech are listed in the Installation Quick Guide available at the Napatech Documentation Portal.
With the acquisition of Altera, Intel® has enabled the Programmable Acceleration Card (PAC) with Intel® Arria® 10 GX FPGA. This new card allows FPGA developers to create AFU (Accelerator Functional Units) that can be deployed on the card and bring FPGA-based value-add to the application.
The OPAE framework
Intel has developed a framework SDK – the Open Programmable Acceleration Engine (OPAE) – that operates with terms like blue and green bitstreams, using the colors to describe the internals of the Intel FPGA. The blue bitstreams are FPGA functional blocks delivered by Intel to make the card work. It contains IO logic for all the surrounding peripherals like PCI, SDRAM, and QSFP+. The green bitstream is where the user code (AFU) is located. The blue bitstream abstracts the IO via standardized APIs enabling the green bitstream to be easily ported to new blue bitstreams on other HW platforms.
The OPAE framework strives to ensure that the developer of an AFU only needs to concern him/herself with the AFU specifics and not the bring-up of the entire FPGA. The server application layer of the OPAE contains a driver layer giving the user access to acquire the FPGA, reset the FPGA, read/write to the FPGA, etc., all via standardized functions. The OPAE framework also provides functions like memory allocate, which can be seen both by the FPGA and the CPU.
The Napatech firmware is a green bitstream that interfaces with the blue bitstream components and enables the Napatech driver suite to interact with the Napatech firmware as if it were Napatech hardware. Normally, Napatech applies both blue and green bitstreams on its own hardware, so using only the green bitstream has been challenging, yet successful.
PAC Hardware
The PAC hardware consists of:
·a QSFP+ enabling a single 40Gbps or 4x10Gbps (via breakout cables)
Napatech has a long history of creating its own SmartNICs, but with the collaboration between Intel and Napatech, it is now possible to buy an Intel FPGA based NIC and get Napatech software to run on this non-Napatech hardware. The Napatech software on the Intel hardware enables full 40Gbps zero packet loss RX/TX both on 4x10Gbps and 1x40Gbps. Besides zero packet loss, key Napatech features like deduplication, correlation key generation, flow matching, pattern match, etc. become available as does the highly flexible tuple matcher used for load distribution of traffic. Napatech has enabled the Intel card to work as a plug-n-play solution for several monitoring/security applications like Suricata, Snort, Bro as well as the TRex traffic generator which means that it is also integrated into DPDK when running the Napatech firmware.
Performance
With the Intel PAC running Napatech Software, Intel now has a hardware platform that can claim zero packet loss at 40Gbps, which to my knowledge has not previously been possible. We have been testing internally with both the PAC and Intel X710 – and only the PAC with Napatech Software can ensure zero packet loss. Running e.g. Suricata on X710, the packet loss starts to occur at ~ 1Gbps, but with the Intel PAC, it runs without loss at ~40Gbps.
Final thoughts
I see great potential for the PAC platform and OPAE going forward and look very much forward to seeing what use cases it will fulfill and how the platform will evolve. Hopefully the PAC will enable more FPGA business, both from a hardware and firmware perspective. I don’t think the current PAC is a one-fits-all platform, but it can be the catalyst to spin-off a general interest in FPGA and other form factor boards that all feature the OPAE to enable portability from an application point of view. And in the end, that is what matters: that the application is accelerated.
Intel’s next PAC with a Stratix 10 looks interesting and much more similar to the Napatech hardware products, so let’s see what the future brings.
