Introduction
The three basic protocol testing checks are:
- Correctness: To check if the packet is received as expected
- Bandwidth: To check how many packets were sent per time unit (mostly a second)
- Latency: To check how long it takes for a packet to be transmitted across a network
The most common types of protocol testing are:
- Conformance testing: Performed to evaluate if the products adhere to the protocol specifications
- Interoperability testing: Performed to check if the product is compatible with devices/systems/software applications from various vendors
- Simulation testing: Scenarios are created similar to the real-time use cases to evaluate the function of a product
Why Protocol Testing Services are Required for Industries?
Protocols Adhere to Industry Standards
Interoperability is one of the most essential needs of a connected system. This testing helps evaluate if the various devices in a network are interoperable and meet industry standards.
Assess Risk
Industrial devices and systems face security risk with the increasingly thin boundary between IT and OT. It is important to check devices and systems for access control and open ports that could become vulnerable points for cyberthreats. This testing also helps check if there is any interference from other devices that could disrupt performance. Industries can leverage protocol testing to check if there are any such potential risk areas and correct them in advance. It also helps build a secure connected system.
Evaluate Security
Security breaches are one of the biggest challenges faced by connected networks. Design flaws, weak software systems and unencrypted communication can lead to security issues. Protocol testing helps identify the weak links in the network to prevent the possibility of cyber threats and security breaches.
