| Abstract | High-speed packet content inspection and filtering devices rely on a fast multi-pattern matching algorithm which is used to detect predefined keywords or signatures in the packets. These signature sets are large (e.g., thousands) and complex. Multi-pattern matching is known to require intensive memory accesses and is often a performance bottleneck. Another problem is how to update the inconstant rule set from new attacks without halting the inspection. Hence, specialized fast dynamic pattern matching algorithms scalable for long rules are required for on-line speed deep packet inspection. We proposed a fast dynamic deep packet inspection algorithm using two pipelines which was flexible loosely coupled framework. In the fast pipeline, multiple parallel Counting Bloom filter engines which can perform fast dynamic query were adopted to achieve high throughput. Based on the principle of locality of programs, we set a threshold length for the scalability for long rules. In the relatively slow pipeline, we adopted dynamic pattern matching algorithm to distinguish the suspicious packet came from the fast pipeline. The analysis and the evaluation show that the high throughput of the algorithm can satisfy the wire speed dynamic inspection requirement when the low resource consumption further improves the scalability. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
