SPDY is a versioned protocol. SPDY control frames contain 15 dedicated bits to indicate the version of protocol used for the current session. [22] Version 1: version 1 of the SPDY protocol is not used anymore. [22] Version 2: soon [as of?] to be discontinued. Nginx supports SPDY/2 in versions prior to 1.5.10. [23]
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 trademark issues.
Tabular Data Stream (TDS) is an application layer protocol used to transfer data between a database server and a client. It was initially designed and developed by Sybase Inc. for their Sybase SQL Server relational database engine in 1984, and later by Microsoft in Microsoft SQL Server .
The SPID algorithm can detect the application layer protocol (layer 7) by signatures (a sequence of bytes at a particular offset in the handshake), by analyzing flow information (packet sizes, etc.) and payload statistics (how frequently the byte value occurs in order to measure entropy) from pcap files.
An application layer is an abstraction layer that specifies the shared communication protocols and interface methods used by hosts in a communications network. [1] An application layer abstraction is specified in both the Internet Protocol Suite (TCP/IP) and the OSI model . [ 2 ]
WhatPulse, a statistical (input, network, uptime) measuring application. Wireshark (formerly Ethereal), a graphical packet-capture and protocol-analysis tool. XLink Kai, software that allows various LAN console games to be played online; Xplico, a network forensics analysis tool (NFAT).
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
Protocol analyzers vary in their abilities to display and analyze data. Some protocol analyzers can also generate traffic. These can act as protocol testers. Such testers generate protocol-correct traffic for functional testing, and may also have the ability to deliberately introduce errors to test the device under test's ability to handle errors.
