Maximizing Throughput in SDV Operation

RTSP/MHA Paired Port Assignment
Prior to APEX1000 2.0, the APEX1000 could report a single pair of GigE ports to the
ERM. Users could then enable all 48 QAMs for SDV mode, allowing the ERM to map
streams from any enabled GigE input port to any enabled QAM output port. However,
this also meant that the APEX1000 was constrained by the output bandwidth of a single
GigE processor limited to 931 Mbps output bandwidth (approximately 24 QAMs).
APEX1000 2.0 introduced an RTSP/MHA mode option known as Paired Port Assignment.
This mode logically divides the APEX into two devices which are reported to the ERM:
•
GigE Port 1 and 2: QAMs 1 – 24 (1a-1h, 2a-2h, 3a-3h)
•
GigE Port 3 and 4: QAMs 25 – 48 (4a-4h,5a-5h,6a-6h)
Each GigE processor is assigned a strict input-to-output mapping:
Device Name "APEX-A"
NextHopServer Port "X"
Streaming Zone "Z"
Device Name "APEX-B"
NextHopServer Port "Y"
Streaming Zone "Z"
