MC 专题的由来： 感知体验(perceptual experience)的重要性 Providing high-quality streaming services over a best effort and shared infrastructure such as the Internet is nontrivial. This is increasingly placing loads on network elements to deliver streaming content with high perceptual quality, including content delivery networks(CDNs),overlay networks,video on demand (VoD),and Internet television (IPTV)infrastructures.Network service providers need to infer,predict,and improve perceptual experience to ensure long-term success.
