packet header

A group of fields in a network packet that describes its content, all required destination addresses to reach its target, and all source information necessary to allow a response to come back. See packet and header.

We use Netmate in the Detection Agent to capture received packets and recognize them as distinguishable traffic flows in accordance with the 5-tuple information of packet header, and the Detection Agent extracts features from the flows and transforms them into feature vectors for analysis.
This is a non-intrusive model based upon the packet header information, which provides certain algorithms for evaluating the audiovisual quality of IP based video services.
(b) The Consistency Checker adds the newly created object to the list of packets that goes from 1 to the value of Number of packets contained in the received packet header field.
Parameter Value Network size 400 m x 400 m Number of the nodes 80 to 160 Packet size 288 bits Initial energy 10 J Transmission range 40 m Propagation model Two-Ray Ground Physical layer wireless-phy MAC layer IEEE 802.11 Data rate 11 Mbps FIGURE 8: Packet header format in proposed scheme.
shallow packet inspection, as it looks not only at the packet header but
Additionally, since sFlow provides the complete packet header information, the host MAC address is available to provide the ability to uniquely track a host IP address.
This includes the packet header process using a specialized RISC processor.
An interesting work by [20] presented a novel decision-tree based linear algorithm that targets the recently proposed OpenFlow that classifies packets using up to 12 Tuple packet header fields.
Geographic unicast is more efficient for long nonbranching path segments, and source multicast is desirable with branching path segments; (4) it further decreases the packet header size by using the multicast packet with a small node ID instead of potentially large position information; (5) overall, the reduced computational overhead, encoding overhead, and packet header size enable EAGER to consume less energy than location-based or source-based multicast protocols.
The software part executes tasks responsible for memory checking, as packet header fields typically reside in the processor's cache memory, whereas the hardware part realizes the most time and power consuming operation, that is, the least significant bit (LSB) encoding functionality.
Most network and security equipment based on general purpose processors and NPUs make simple forwarding decisions based on coarse criteria by parsing packet header fields, often expressed as 2-, 3-, 5-and 7-tuple lookups.
Examples of use include: SPI message monitoring of specific slave select lines; continuous, filtered data packet header evaluation; long-term bus monitoring; in-lab development; on-site, after-installation servicing for chip-to-chip communication emulation, IP evaluation, etc.
