Description
Summary:There has been an increasingly popular trend that content caching becomes an inherent underlay capability in network routers. This poses new challenges, and we believe that if not well provisioned, such capability may even degrade network performance. Among the challenges, we are interested in how the in-network caching capability should be best provisioned to improve the overall network performance. To address this challenge, we propose a collaborative caching scheme guided by traffic engineering (TECC) for the emerging content-centric networks. In particular, we decouple collaborative in-network caching and traffic engineering via the primal-dual decomposition. Our evaluations, although preliminary, suggest that the improvement is as much as 80% compared to collaborative caching without guidance of traffic engineering.
