Ethernet Testing – For Efficient Network Performance
Ethernet routers and switches are among the fastest-growing devices in routing and switching market segment. Carrier Ethernet is being deployed in many networks to deliver enhanced services to customers. Testing this carrier Ethernet becomes vital for service providers because they need to ensure that the network infrastructure meets industry standards and other functional criteria.
According to MSDN library, a traditional Ethernet testing requires two computers. One of them holds the device to be tested, while the other receives and sends data to the testing device. There will separate lines of communication between the two computers that is used to derive data about the ongoing tests.
The Metro Ethernet Forum has defined conformance requirements that need to be cross checked during performance testing. Each phase of carrier Ethernet has its own testing requirements; and as network size increases it becomes important to test new and legacy devices that are added to the network, for interoperability.
Ethernet testing also encompasses performance testing of network subsystems and finally the entire network. Network testing has to be conducted to derive the break even points that are eventually used to analyze the capacity of the network.
Networks also need to be guarded from external threats and thefts. Security is a major cause of concern because the network carries high volumes of parallel data. Security testing must ensure that there is no leakage between VLAN, MAC-in-MAC and VPN traffic.
Testing tools that are available in the market not only combine multiple protocols, but enable network emulations that simultaneously include Q-in-Q, MAC-in-MAC, and PBB-TE/PBT – at line speeds up to 10 GBPS. These tools enable efficient testing of conformance, interoperability, function, performance, service and scalability of the network.
Because organizations are expanding at a faster rate, it becomes imperative for them to implement robust network infrastructures; and Ethernet testing with efficient tools can definitely aid in deployment of efficient network systems.
