The IP Packet Processor enables efficient IP networking and transport over satellite by adding routing capability with very low overhead encapsulation, header compression, payload compression and Quality of Service (QoS) to the CDM-625 Advanced Satellite Modem. The advanced QoS combined with header and payload compression ensures the highest quality of service with minimal jitter and latency for real-time traffic, priority treatment of mission critical applications and maximum bandwidth efficiency.
The IP Packet Processor incorporates industry-leading header compression for IP traffic. Header compression can reduce the 40 byte IP/UDP/RTP header to as little as 1 byte. For TCP/IP, the 40 byte header is reduced to as little as 3 bytes. For applications such as Voice over IP (VoIP), header compression can provide bandwidth savings exceeding 60 percent. With header compression, the same voice call needs about 8.5 kbps — a saving of almost 65 percent. And, bandwidth requirements for typical Web/HTTP traffic can be reduced by 10 percent or more with TCP/IP header compression.
The IP Packet Processor features industry-leading payload compression for IP traffic. Implemented in the hardware for maximum throughput and efficiency, payload compression can reduce the required satellite bandwidth by as much as 40-50 percent. The IP Packet Processor also includes Comtech EF Data’s patent-pending very low overhead Streamline Encapsulation (SLE), which can reduce the encapsulation overhead by as much as 65 percent compared to industry-standard HDLC. Multi-level QoS is also incorporated to ensure the highest quality of service with minimal jitter and latency for real-time traffic, priority treatment of mission critical applications and maximum bandwidth efficiency.
