If only one STB has joined an IGMP video stream, then changing its channel represents the existing CCT without pre-selection.
The layer 3 device replicated typical IGMP Processing delays in the range of 10 to 20 msec per channel change.
This mean time reduction shown in Table 1 minus the fixed round trip Network Delay of 1198 msec left approximately 12 msec remaining to account for the IGMP Processing delay on the otherwise unloaded layer 3 device.
With the expected IGMP Processing delay falling below the measurement accuracy of the test, the entire theoretical reduction forecast cannot be stated to be an absolute fact; however, the mean reduction results were consistently slightly above the round-trip Network Delay in line with the expectations for the IGMP Processing times.
The results corroborate that a successful IPTV channel pre-selection technique will likely result in an expected CCT reduction of two times the Network Delay plus the IGMP Processing time.
Customers are increasingly adding technologies such as VoIP and VLANs to their requirements lists, while still demanding optimum security with enhancements such as Static Port Security and IGMP Snooping.
The Spring 06 LEC event focused on evaluating the seamless integration of the voice infrastructure into an IP/MPLS network comparing the IPTV service delivery of hundreds of channels over Multicast Layer 3 VPNs with data multicast distribution tree configuration mode and Hierarchical Virtual Private LAN service (H-VPLS) with IGMP snooping enabled on the access side.
The iMG800 is designed to simultaneously support IP Video and data services with IGMP, QoS and routing capability, full inspection firewall, and NAT for network security.
The TK13SV7 provides a low power design with advanced features and functions, such as multiple port configuration; per-port provisioning, monitoring, control and IGMP snooping; flexible support for 10/100/1000 mb/s; two full-featured voice channels supporting voice activity detection, line echo cancellation, and three-way conferencing; support for multiple codecs; and advanced routing.
1x port-based security, MAC Filter, Limited MAC Count and an IGMP profile filter.
Other benefits of these products include multicast applications such as IGMP snooping, proxy and Multicast VLAN Registration (MVR).
Comtrend offers a broad array of leading-edge, high-quality, DSL products that embeds ADSL, ADSL2+, Bonded ADSL2+ and VDSL2 technologies to support triple-play voice, video and data applications, including IP-Video, VoIP, optional WiFi drops and industry-standard QOS with VLAN traffic assignment, IGMP Snooping and IGMP proxy, which provides efficient traffic management and control in IP multicast applications.
