Resource reservation in information centric networking

Abstract

Quality of Service (QoS) is a crucial mechanism where the network manages its finite resources to meet the demands promised for some applications at the cost of forsaking some other applications' needs. Information Centric Networking (ICN), although great at features such as name based addressing, decoupling host from data, in network caching, etc., still offers best effort service. This restricts the network suitability for safety critical applications such as tele-operated driving or real-time multimedia applications that often demand guaranteed bandwidth and delay. Reserving sufficient resources as well as establishing an admission control mechanism is one way to ensure performance guarantees. We present a paper emphasizing the need for a "better than best-effort service" in Named Data Networking (NDN), the functionalities to fulfil for a QoS mechanism and the open challenges in establishing resource reservation in NDN.
