Recent work in string matching has focused on offloading string matching to hardware realizations in order to achieve time and space efficiencies. However, any form of implementation would have to maintain a threshold performance in order to keep with the packet data rate. While trying to maintain this threshold, control-unit is forced to either drop some packets or some rules. In this work, we present a packet priority technique that prioritizes the packets such that there is a high probability that the potentially malicious packets are detected within the threshold limit.

However, point-to-point oriented network such as IEEE 802.16 introduces some issues in applying conventional standard IPv6 neighbor discovery protocol (NDP). Following the previous 3GPP model for IPv6 NDP is not flexible in IPv6 link configuration since it assigns different network prefixes to each subscriber stations. We presents a mechanism which can allocate a common network prefix to all subscriber stations under the same IPv6 link.

While mobile IP has been designed for mobility management in IP networks, it still has a high latency and signaling overhead during handoff. Some proposals for seamless handover support have been published and some analytic work on their performance done. However, there are still many issues in multimedia and real-time service provisioning over mobile IP networks. One of the main reasons is that the current IP network is best effort based and cannot provide QoS guarantee for real-time services. In this paper, we propose a flow-based routing scheme in mobile IPv6 networks to support real-time traffic by using the flow label field in IPv6 packets. The proposed scheme takes the advantages of rapid establishment of a flow and fast forward of packets based on flow state information that lowers the packet processing time and transmission delay; the hierarchical network structure that reduces signaling loads, and a fast flow handoff algorithm that ensures minimal handover latencies and packet losses","PeriodicalId":247315,"journal":{"name":"2006 8th International Conference Advanced Communication Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131948905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
