How to provide differentiated services for diverse types of traffic poses challenges to the retrieval process of Content Centric Networking (CCN).Inspired from the idea of differentiated service

a diverse content delivery scheme based on traffic types is proposed.When requesting contents

three delivery models

namely

persistent push

parallel prediction and one-one request

are proposed according to the characteristics of the requested traffic.When making the caching decision

three on-path caching policies

including transparent forwarding

probabilistic edge caching and gradual push are implemented respectively to match the delivery models.The simulation results show that the scheme can decrease the request latency

achieve higher cache hit ratio

while improving the overall performance of content delivery with a small amount of additional control overhead.
