内容缓存已成为网络路由器中固有的可扩展性，这一趋势越来越普遍。这提出了新的挑战，我们认为，如果没有很好地提供，这种能力甚至可能会降低网络性能。在这些挑战中，我们感兴趣的是如何最好地提供网络缓存功能，以提高整体网络性能。为了解决这一挑战，我们提出了一个合作的缓存方案指导下的流量工程（TECC）的新兴内容为中心的网络。特别是，我们解耦协作网络缓存和流量工程通过原始-对偶分解。我们的评估，虽然是初步的，表明改进是多达80%相比，没有指导的流量工程的协作缓存。
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.
