Apposite Technologies is the leader in easy-to-use, professional-quality network simulation products. Apposite’s Linktropy and Netropy WAN emulation appliances simulate link bandwidth, delay, loss, congestion, and other network impairments to test the performance of applications in the lab under a spectrum of real-world conditions.
Offering a unique combination of ease-of-use, test lab-level precision, and unmatched prices, Linktropy and Netropy WAN emulators are widely deployed by leading enterprises, application and equipment vendors, telecoms carriers, test labs, and government and military organizations across North America, Europe, and Asia.
Linktropy WAN emulators simulate a single link through each pair of interfaces, offering the simplest configuration possible. If you need to emulate a single set of conditions between two networks, Linktropy is the product for you.
Netropy advanced network emulators simulate up to 15 separate WAN links, each with their own bandwidth, delay, and loss characteristics, through each pair of physical ports. Packets can be assigned to individual links by IP address range, VLAN, or any other packet specifier.
Netropy also offers advanced emulation and administrative capabilities for complex requirements or multi-user environments.
What is WAN Emulation?
Today’s dispersed workforce requires responsive access to a wide variety of centrally managed and cloud-based applications. IT managers and network administrators need to predict, optimize, and troubleshoot how these applications will perform when installed on the production network while application developers need to replicate realistic customer conditions for development, QA testing, and customer support.
By simulating the conditions of the wide area network, Apposite WAN emulators allow users to test applications under a spectrum of real world conditions in a controlled, repeatable test environment. By making emulation quick and easy, with emulators that can be configured in minutes without training or specialized expertise, Apposite ensures the smooth roll-out of new applications and assists in optimizing the performance of existing applications.
Testing provides critical insights into application performance:
- Throughput: Bulk data transfers such as storage replication and file transfer need to fully utilize the available bandwidth to complete quickly.
- Responsiveness: Users depend on responsive interaction with transaction-based applications such as web and database systems
- Quality: Voice, video, and other collaboration tools need to provide a high quality experience for teams to work efficiently between disperse locations.
