Efficient and Reliable Network Emulator
Reliably replicate real-world network conditions to optimize app and device performance before product release. Maxwell Pro emulates mobile, cloud, and WAN networks, recreating real-world adverse network conditions like network congestion, slow links, time-outs, and other adverse network conditions.
NOTE: For purposes of network emulation without protocol testing we suggest IWL’s KMAX series of products
Comprehensive TCP/IP Testing Suite
Maxwell Pro TCP/IP Tes-suites include tests for ARP, ICMP, DHCP, IPv4, IPv6, TCP and UDP. These tests help quality assurance engineers to find bugs in their TCP/IP network protocol stacks.
Discover Application Problems, Before They Become Problems

Test, diagnose and remediate application performance in new releases by replicating the production network in the lab.
- Detect and track individual flows while remaining undetectable to other devices on the network.
- Intelligently test thousands of code paths, not just the most common paths, in a stateful manner.
- Simplify rigorous, repeatable, regression testing.
- Multiple flows and stateful operation.

Greater granularity and fidelity when emulating real-world networks
Discover problems earlier, fix them, and release higher-quality products and applications.
With Maxwell Pro’s powerful network emulator software, you can achieve greater granularity and fidelity when emulating real-world networks, allowing you to discover and address problems early in the development process. By emulating a wide range of network technologies and applications, such as VoIP, video conferencing, SANs, wireless, mobile, and VPN, Maxwell Pro offers extensive capabilities to ensure the quality and performance of your products and applications.
- Maxwell Pro’s flexible, scriptable, programmable power enables an abundance of capabilities
- Emulate all network scenarios, including VoIP, video conferencing, SANs, wireless, mobile, VPN, and many more with Maxwell Pro.

Add time-varying impairments to your emulation
Real world networks change their behavior over time. And so should your network emulation scenario.
- Create a network emulation that varies the impairment parameters over any time period
- Specify a time-varying expression for any metric, using equations, piecewise curves, or shaped pulses
We looked at a number of products, but selected Maxwell because of the ability to create custom impairments and custom filters. This is very useful in our testing environment.

Maxwell Pro TCP Test Suite
TCP Testing & Compliance
Saving you valuable time and resources by identifying and resolving issues early in the development process. By conducting thorough testing, you can enhance the reliability and security of your apps and devices, preventing potential failures and safeguarding sensitive data. Ensure the robustness and integrity of your TCP implementations with Maxwell Pro’s TCP/IP Test Suite, providing you with the confidence to deliver high-quality products that meet the demands of your customers.
Test Your TCP Implementation
As a vital communication standard, Transmission Control Protocol (TCP) ensures seamless data exchange between network nodes. By leveraging the TCP Test Suite, engineers can proactively detect and address bugs and security vulnerabilities in their applications and devices prior to deployment.
Finding and fixing TCP bugs prior to deployment assures secure, interoperable, high quality apps and devices with fewer deployment failures — avoiding costly recalls or on-premise repairs.
Ensure your TCP implementation is sufficiently robust and not vulnerable to the wide range of attacks in today’s Internet.
Bug Detection: Testing helps uncover bugs in your TCP implementation, enabling you to rectify them before deployment and ensuring smooth operation of your applications and networks.
Enhanced Security: Testing helps uncover security vulnerabilities in your TCP implementation, allowing you to strengthen the security measures and protect sensitive data from potential threats.
Compatibility Verification: Testing ensures that your TCP implementation is compatible with various network environments and devices, avoiding compatibility issues that may hinder communication.
Unique Test Cases
The TCP Test Suite contains unique test cases that take on parameters for greater coverage. The tests ensure TCP compliance through vulnerability and robustness testing, with tests for both IPv4 and IPv6.
Customization
The Maxwell Pro TCP Test Suite can provide you with the customization and flexibility you need to accurately test your implementation and meet your schedules.
Testing TCP for Compliance and Robustness

Maxwell Pro TCP/IP protocol test suites offer the following test suites to help quality assurance engineers find bugs in their TCP/IP protocol stacks.
Hardware Requirements
The TCP/IP Test Suite operates on the Maxwell Pro platform and has the same hardware requirements.

Test multimedia G.1050

The ITU-T Recommendation G.1050 provides a standardized network model for evaluating multimedia transmission performance over the internet. Maxwell Pro’s G.1050 tests help product manufacturers verify proper device performance under a range of known, deployed network configurations including common network anomalies and impairments. Validate application performance and guarantee the success of your cloud-based initiative with pre-deployment testing.
With Maxwell Pro you can test:
- Storage in the cloud applications under limited bandwidth connections
- Audio interaction over the internet for gaming applications
- Multimedia devices containing video, voice streams & more
