Hardware Assisted Packet Filtering Firewall
A packet filter is a hardware or software mechanism that can be configured to select packets from a traffic stream based on some criteria. Many research works have been done in the past in the area of classifying packets based on one or more packet header fields. Those works are directed towards finding efficient algorithms and implementation architectures for high speed routing, Quality of Ser...
متن کاملA Method to Reduce Effects of Packet Loss in Video Streaming Using Multiple Description Coding
Multiple description (MD) coding has evolved as a promising technique for promoting error resiliency of multimedia system in real-time application programs over error-prone communicational channels. Although multiple description lattice vector quantization (MDCLVQ) is an efficient method for transmitting reliable data in the context of potential error channels, this method doesn’t consider disc...
متن کاملMethod to Measure Packet Processing Time of Internet Hosts with Specialized Packet-Capture Line Card
The packet processing time (PPT) of a host is the time elapsed between the arrival of a packet at the data-link layer and the time the packet is processed at the application layer of the TCP/IP protocol stack. To measure the PPT of a host, stamping the times when these two events occur is needed. However, popular network interface cards (NICs) do not provide such time stamping facility. The use...
متن کاملPlab: a packet capture and analysis architecture
We designed and implemented a software for packet capture and analysis and to extract samples of what we identified as random variables. We called it PLAB. We tried to design a program flexible enough but that needed as few processing resources as possible, to be capable of analyzing traffic traces of hundreds of millions packets. In this chapter we illustrate the main architecture of the softw...
متن کاملpktd: A Packet Capture and Injection Daemon
Administrators can be highly reluctant to run foreign measurement tools on their hosts because (a) such tools frequently require privileged execution in order to transmit customized measurement packets and/or to passively capture network traffic, and (b) the administrators lack mechanisms to control the rate, duration, type, destination, and contents of traffic generated by the measurements. We...
