The exhaustion of IPv4 addresses has led to the transition to IPv6 becoming a major task for the Internet. Providing IPv6 users with accessibility to IPv4 services has been one of the most challenging tasks during the IPv4/IPv6 transition. However, some protocols contain IP addresses in the application layer, resulting in incompatibilities in traversing the network-layer translators. In this paper,...
Ternary Content-Addressable Memory (TCAM) is a popular hardware device for fast IP address lookup. High link transmission speed of Internet backbone demands more powerful IP address lookup engine. Restricted by the memory access speed, the lookup engine for next-generation routers demands exploiting parallelism among multiple TCAM chips. However, most existing schemes improve lookup performance and...
Ternary Content-Addressable Memory (TCAM) is a popular hardware device for fast IP address lookup. High link transmission speed of Internet backbone demands more powerful IP address lookup engine. Restricted by the memory access speed, the lookup engine for next-generation routers demands exploiting parallelism among multiple TCAM chips. In this paper, we propose a fast lookup and power-saving scheme...
Chip-level parallel TCAMs were deployed to circumvent the limitation of a single TCAM. In this paper, we propose a crossed address range division and integral caching scheme. We improve the update efficiency significantly by buddy update method while keep low power dissipation by decreasing the number of the triggered TCAMs access in each lookup operation. The lookup throughput is ultra high through...
Voice interaction is a conversation mode between human and computer pursued by people. Based on the .NET platform, the techniques of data binding and text to speech are used to create voice homepages at the web sites of online shopping, and the technique of streaming media is used to transfer data, which make it possible to browse text and play voice simultaneously, and even enable a blind person...
Since the Internet uses destination-based packet forwarding, malicious attacks have been launched using spoofed source addresses. In an effort to enhance the Internet with IP source address validation, we prototyped an implementation of the IPv6 source address validation architecture (SAVA) and conducted the evaluation on an IPv6 test-bed. This paper reports our prototype implementation and the test...
