PacketCable 1.0 comprises eleven specifications and six technical reports which define call signaling, quality of service (QoS), codec usage, client provisioning, billing event message collection, public switched telephone network (PSTN) interconnection, and security interfaces for implement a single-zone PacketCable solution for residential Internet Protocol (IP) voice services.
Wireshark is a free and open-source packet analyzer.It is used for network troubleshooting, analysis, software and communications protocol development, and education. . Originally named Ethereal, the project was renamed Wireshark in May 2006 due to tradema
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header.It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header.
A capture file saved in the format that libpcap, WinPcap, and Npcap use can be read by applications that understand that format, such as tcpdump, Wireshark, CA NetMaster, or Microsoft Network Monitor 3.x. The file format is described by Internet-Draft draft-ietf-opsawg-pcap; [5] the current editors' version of the draft is also available. [6]
PC/TCP Packet Driver is a networking API for MS-DOS, PC DOS, and later x86 DOS implementations such as DR-DOS, FreeDOS, etc. It implements the lowest levels of a TCP/IP stack, where the remainder is typically implemented either by terminate-and-stay-resident drivers or as a library linked into an application program.
At the transmitter, the calculation is performed before the packet is sent. When received at the destination, the checksum is recalculated, and compared with the one in the packet. If discrepancies are found, the packet may be corrected or discarded. Any packet loss due to these discards is dealt with by the network protocol.
Packet Sender is an open source utility to allow sending and receiving TCP and UDP packets. It also supports TCP connections using SSL , intense traffic generation, HTTP(S) GET/POST requests, and panel generation.
