Agilent N2X accurately profiles IPTV channel zapping performance by:
- Emulating real-world network conditions including simultaneous PPPoX, DHCP, and IGMP sessions and traffic
- Scaling to hundreds of TV channels and thousands of subscribers
- Simulating realistic channel zapping scenarios including thousands of IPTV viewers Channel ”Zapping” at the same time
- Providing hardware time stamping to ensure measurement repeatability and reliability.
