Information-Centric Networking (ICN) is proposed to address the inefficiency of content delivery of IP networks from the perspective of architecture. In contrast, Content Delivery Network (CDN) is an overlay solution in current IP networks. We believe that even though ICN is fully deployed, there is still a role for CDNs to play in ICN networks. Since ISPs in ICN will replicate and forward contents...
BGP measurement is important for monitoring and understanding the Internet anomalies. Most of the previous works on BGP measurement rely on aggregated statistics from BGP monitors, e.g., total updates. However, BGP events may have quite limited visibility. Therefore, merely investigating aggregated data may lead to misunderstanding Internet instability, e.g., overestimating the impact of monitor-local...
Ternary Content Addressable Memory(TCAM)-based multidimensional tables are widely used to implement Access Control Lists (ACLs) for Internet packet classification and filtering, and have also become attractive for constructing the forwarding tables of Internet routers and the flow tables of Openflow switches, where multiple fields are generally used to match incoming packets. However, as such tables...
The demand for faster failure-recovery in the Internet has led to the development of several IP Fast Reroute (IPFRR) schemes, which are all too computationally expensive or unsatisfactory in protection coverage. In this paper, we propose Minimum Protection Cost Tree (MPCT) for IPFRR using Tunnel. By constructing an MPCT for each hypothetical failed neighbor, MPCT finds the protection paths for all...
In recent years, the core-net routing table, e.g., Forwarding Information Base (FIB), is growing at an alarming speed and this has become a major concern for Internet Service Providers. One effective solution for this routing scalability problem, which requires only upgrades on individual routers, is FIB aggregation. Intrinsically, IP prefixes with numerical prefix matching and the same next hop can...
The demand for faster failure-recovery in pure intra-domain IP networks has led to the development of several IP Fast ReRoute (IPFRR) mechanisms. However, these mechanisms are all either too computationally expensive, or fail to provide satisfiable protection coverage. For these reasons, IPFRR schemes have yet to see widespread commercial deployment. In this paper, we present a new IPFRR mechanism...
