This MIB module defines a set of objects for monitoring the
Visual Quality Experience Server (VQE-S) operational status. 
        
VQE-S receives the channel lineups from the VQE Channel 
Provisioning Tool. Each channel is uniquely identified with 
a Service Delivery Protocol (SDP) description, including:
 - IP multicast address 
 - Real-Time Protocol (RTP) port number 
 - Real-Time Control Protocol (RTCP) port number
 - Unicast feedback target address
 - RTP and RTCP port numbers 
        
VQE-S supports Error Repair (ER) and Rapid Channel Change (RCC) 
technologies to improve the delivery of IPTV video services. 
When a VQE client (VQE-C) notices a missing packet or a group 
of missing packets, it sends an RTCP Feedback Generic NACK 
to the VQE-S. The VQE-S looks into its cache, and if it has any 
of the requested packets, it sends them immediately to the VQE-C
as RTP retransmission repair packets. When the VQE-C detects a 
channel change, it immediately sends an RTCP Picture Loss 
Indication (PLI) NACK to the VQE-S to request the information 
for the VQE-C to recover its picture. Both ER and RCC are 
unicast retransmissions.
