CTOG-250 Advanced VSAT Solutions Traffic Optimization Gateway
The Comtech CTOG-250 Advanced VSAT Solutions portfolio provides high-performance satellitebased communication solutions for a diverse range of applications, including broadband maritime, offshore communications, mobile backhaul with RAN optimization, IP trunking and backhaul, , corporate and enterprise networks, emergency and disaster recovery.
Incorporating advanced technologies developed by Comtech EF Data, AHA Products Group, Memotec and Stampede, the solutions provide unmatched performance, industry-leading bandwidth efficiencies and network optimization – while minimizing Total Cost of Ownership.
Ultra High Performance Packet Processing
CTOG 250 is designed to work with the CDM-800 Gateway Router and provides high performance packet processing and traffic optimization functions for the shared high-speed DVB-S2 outbound. It also includes the ACM/VCM controller.
Based on a carrier grade server platform, with dual multi-core processors, Comtech CTOG-250 is designed to offload packet processing from the CDM-800 for large networks requiring higher throughput. CTOG-250 processes the incoming IP datagrams and packages them into DVB-S2 baseband frames for transmission to CDM-800 via Gigabit Ethernet interface.
Outbound Adaptive Coding & Modulation (ACM)
ACM allows each remote in a shared outbound to achieve maximum efficiency and throughput by operating at the best modulation and code rate (MODCOD) subject to current conditions. Each remote reports the current receive conditions to the ACM controller at the Hub, which adjusts the MODCOD for traffic destined to that remote. The ACM controller selects the MODCOD on a frame by frame basis to optimize efficiency and availability.
|
Without ACM the shared outbound would have to be dimensioned for the most disadvantaged remote leading to significantly inefficient operation. ACM maximizes network efficiency and throughput under all conditions – be it location disadvantage, rain fade, inclined orbit operation, interference or other impairments. Comtech EF Data’s ACM controller also includes dynamic remote route discovery which simplifies hub configuration by automatically discovering remote routes and adding them to the ACM controller. |
