Agile L2 Access Switch Solution for Converged Data, Video and Voice Networking Incorporating data, video and voice communications into a single IP network provides more effective communications, centralized IT management, and lower overall deployment cost for the entire organization. This is why an increasing amount of businesses, educational institutions, and hotels are adopting such IP-based services as VoIP, video conferencing, IP surveillance, and IPTV. Yet such converged deployments pose many challenges to the IP network. IT staff need to ensure consistent performance for critical applications, provide sufficient isolation and network security, and shape network traffic to meet the demands of diverse deployments.
