Apparent Networks and Nortel Pair Up to Add Network Awareness to VoIP Solutions; Network Assessment Software Simplifies the Multi-Vendor Environment and Proactively Resolves Network Problems.

VANCOUVER, British Columbia -- Apparent Networks, an industry-leading provider of network diagnostic software, today announced an agreement with Nortel(a) (NYSE:NT)(TSX:NT) through which the companies will collaborate to leverage Apparent Networks innovative network analytic technology within Nortel's enterprise VoIP solution.

AppCritical, Apparent Networks' network performance system relies on agent-free IP network assessment software that is capable of instantly and proactively identifying faults that plague many multi-vendor data and voice networks. The solution provides current and predictive perspectives of the network's capability for both data and VoIP delivery and anticipates the impact the two will have on the converged IP network. The focus is on simplifying network complexity to ensure VOIP quality isn't compromised by delays and interruptions

"VoIP equipment vendors are recognizing the value of getting involved early in network management and those that can simplify the multi-vendor network environment from the onset have an advantage," said Irfhan Rajani, Apparent Networks president and CEO. "By assuring VoIP voice quality isn't compromised by poor network hygiene, our customers have experienced reduced support costs, increased customer retention and improved revenues by proactively reducing damage inflicted by degraded networks."

The relationship between Apparent and Nortel is focused on reducing complexity and ensuring the approach to network management is simpler. Network simplicity is a vital step on the path toward full autonomic computing, which increases agility in moving toward an everything-over-IP world and all its benefits.
