Scalable Name Lookup in NDN Using Effective Name Component Encoding

Y. Wang, K. He, +4 authors Y. Chen
Computer Science
IEEE 32nd International Conference on Distributed…
18 June 2012

We propose an effective Name Component Encoding (NCE) solution with the following two techniques: (1) A code allocation mechanism is developed to achieve memory-efficient encoding for name components, (2) We apply an improved State Transition Arrays to accelerate the longest name prefix matching and design a fast and incremental update mechanism which satisfies the special requirements of NDN forwarding process.

Mitigate DDoS attacks in NDN by interest traceback

Huichen Dai, Y. Wang, Jindou Fan, B. Liu
Computer Science
IEEE Conference on Computer Communications…
14 April 2013

We present a specific and concrete scenario of DDoS attack in NDN, where perpetrators make use of NDN's packet forwarding rules to send out Interest packets with spoofed names as attacking packets. Expand

This paper studies the name lookup issue with longest prefix matching, which is widely used in URL filtering, content routing/switching, etc. Expand

On Pending Interest Table in Named Data Networking

Huichen Dai, B. Liu, Y. Chen, Y. Wang
Computer Science
ACM/IEEE Symposium on Architectures for…
29 October 2012

This paper presents a thorough study of Pending Interest Table (PIT) in NDN/CCN and proposes a Name Component Encoding (NCE) solution to shrink PIT size and accelerate access operations. Expand

NameFilter: Achieving fast name lookup with low memory cost via applying two-stage Bloom filters

Y. Wang, T. Pan, +5 authors Qunfeng Dong
Computer Science
Proceedings IEEE INFOCOM
14 April 2013

We design, implement and evaluate NameFilter, a two-stage Bloom filter-based scheme for Named Data Networking name lookup, in which the first stage determines the length of a name prefix, and the second stage looks up the prefix in a narrowed group of Bloom filters based on the results from first stage.

Fast name lookup for Named Data Networking

Y. Wang, Boyang Xu, +5 authors B. Liu
Computer Science
IEEE 22nd International Symposium of Quality of…
26 May 2014

In this paper, we propose a fast name lookup scheme for Named Data Networking via reconstructing the data structure of FIB to support greedy search strategy and improving the basic string-oriented perfect hash table. Expand

BFAST: Unified and scalable index for NDN forwarding architecture

Huichen Dai, Jianyuan Lu, Y. Wang, B. Liu
Computer Science
IEEE Conference on Computer Communications…
24 August 2015

We propose a data structure called BFAST to compose an index that can simultaneously accommodate CS, PIT and FIB in the NDN forwarding architecture. Expand

Parallel Name Lookup for Named Data Networking

Y. Wang, Huichen Dai, J. Jiang, K. He, Wei Meng, B. Liu
Computer Science
IEEE Global Telecommunications Conference…
1 December 2011

We propose a parallel architecture for NDN name lookup called Parallel Name Lookup (PNL) which leverages hardware parallelism to achieve high lookup speedup while keeping a low and controllable memory redundancy. Expand

Greedy name lookup for named data networking

Y. Wang, Dongzhe Tai, +4 authors B. Liu
Computer Science
SIGMETRICS '13
17 June 2013

Different from the IP-based routers, Named Data Networking routers forward packets by content names, which consist of characters and have variable and unbounded length. This kind of complex name… Expand

CASE: Cache-assisted stretchable estimator for high speed per-flow measurement

Yang Li, H. Wu, T. Pan, Huichen Dai, Jianyuan Lu, B. Liu
Computer Science

10 April 2016

We propose CASE, a cache-assisted stretchable estimator, which uses the on-chip memory as the fast cache of the off-chip SRAM. Expand
