In Late Greek, the word prōtokollon referred to the first sheet of a papyrus roll bearing the date of its manufacture. In some instances, it consisted of a flyleaf that was glued to the outside of a manuscript's case and provided a description of its contents. Coming from the Greek prefix prōto- ("first") and the noun kolla ("glue"), prōtokollon gave us our word protocol. In its earliest uses in the 15th century, the word referred to a prologue or preface and also to a record of a document or transaction. In the late 19th century, it began to be used in reference to the etiquette observed by the Head of State of France in ceremonies and relations with other dignitaries. This sense has since extended in meaning to cover any code of proper conduct.
A network protocol is a set of established rules that specify how to format, send and receive data so that computer network endpoints, including computers, servers, routers and virtual machines, can communicate despite differences in their underlying infrastructures, designs or standards.
To successfully send and receive information, devices on both sides of a communication exchange must accept and follow protocol conventions. In networking, support for protocols can be built into the software, hardware or both.
Without network protocols, computers and other devices would not know how to engage with each other. As a result, except for specialty networks built around a specific architecture, few networks would be able to function, and the internet as we know it wouldn't exist. Virtually all network end users rely on network protocols for connectivity.
Network protocols break larger processes into discrete, narrowly defined functions and tasks across every level of the network. In the standard model, known as the Open Systems Interconnection (OSI) model, one or more network protocols govern activities at each layer in the telecommunication exchange. Lower layers deal with data transport, while the upper layers in the OSI model deal with software and applications.
Every packet transmitted and received over a network contains binary data. Most computing protocols add a header at the beginning of each network packet to store information about the sender and the message's intended destination. Some protocols may also include a footer at the end with additional information. Network protocols process these headers and footers as part of the data moving among devices in order to identify messages of their own kind.
A set of cooperating network protocols is called a protocol suite. The Transmission Control Protocol/Internet Protocol (TCP/IP) suite, which is typically used in client-server models, includes numerous protocols across layers, such as the data, network, transport and application layers, working together to enable internet connectivity.
Additional network protocols, including Hypertext Transfer Protocol (HTTP) and File Transfer Protocol (FTP), have defined sets of rules to exchange and display information. Unlike the OSI model, the TCP/IP suite consists of four layers, each with its protocols. The four layers of the TCP/IP model are the following:
Falling into these three broad categories are thousands of network protocols that uniformly handle an extensive variety of defined tasks, including authentication, automation, correction, compression, error handling, file retrieval, file transfer, link aggregation, routing, semantics, synchronization and syntax.
For network protocols to work, they must be coded within software -- either as part of the computer's operating system (OS) or as an application -- or executed within the computer's hardware. Most modern OSes possess built-in software services that are prepared to implement some network protocols. Other applications, such as web browsers, are designed with software libraries that support the protocols necessary for the application to function. In addition, TCP/IP and routing protocol support is implemented in direct hardware for enhanced performance.
Whenever a new protocol is implemented, it is added to the protocol suite. The organization of protocol suites is considered to be monolithic since all protocols are stored in the same address and built on top of one another.
Network protocols are not designed for security. Their lack of protection can sometimes enable malicious attacks, such as eavesdropping and cache poisoning, to affect the system. The most common attack on network protocols is the advertisement of false routes, causing traffic to go through compromised hosts instead of the appropriate ones.
Cybercriminals frequently use network protocols in distributed denial-of-service assaults, which is another typical method of exploiting them. For example, in a SYN flood attack, an attacker takes advantage of the way TCP works. They send SYN packets to repeatedly initiate a TCP handshake with a server until the server is unable to provide service to legitimate users because its resources are tied up by all the fake TCP connections.
Network protocols are what make the modern internet possible since they enable computers to communicate across networks without users having to see or know what background operations are occurring. Some specific examples of network protocols and their uses are the following:
The CAP no longer supports Internet Explorer as Microsoft has set June 15, 2022 as its end-of-life date. Some older CAP browser-based applications might continue to run in Internet Explorer directly, or in Edge using Internet Explorer mode, but the CAP will no longer provide technical support or additional development efforts for use of Internet Explorer. Review Browser and Operating System Requirements.
Laboratories across the country and around the world rely on the CAP to help them stay current with the latest evidence-based practices and maintain quality and proficiency among the entire pathology team.
The CAP Cancer Protocols provide guidelines for collecting the essential data elements for complete reporting of malignant tumors and optimal patient care. These protocols incorporate the latest standards to help pathologists and laboratories keep abreast of the advances and updates in cancer reporting, including:
Synoptic reporting using the CAP electronic Cancer Protocols (eCP) also helps laboratories and hospitals comply with requirements for organizations like the American College of Surgeons Commission on Cancer, the CAP Laboratory Accreditation Program, and more.
The CAP released an accelerated update to the CAP Cancer Uterine Cervix Resection Protocol on April 5th, 2023. This update addresses an incorrect section header text for pTNM Classification to reflect use of AJCC 9th Version content.
On September 21, 2022, the College of American Pathologists released updates to 10 CAP Cancer Protocols. All changes are outlined in the Summary of Revisions with updates now available on www.cap.org.
The College of American Pathologists (CAP) does not permit reproduction of any substantial portion of these protocols without its written authorization. The CAP hereby authorizes use of these protocols by physicians and other health care providers in reporting on surgical specimens, in teaching, and in carrying out medical research for nonprofit purposes. This authorization does not extend to reproduction or other use of any substantial portion of these protocols for commercial purposes without the written consent of the CAP.
The CAP also authorizes physicians and other health care practitioners to make modified versions of the Protocols solely for their individual use in reporting on surgical specimens for individual patients, teaching, and carrying out medical research for non-profit purposes.
The CAP further authorizes the following uses by physicians and other health care practitioners, in reporting on surgical specimens for individual patients, in teaching, and in carrying out medical research for non-profit purposes: (1) Dictation from the original or modified protocols for the purposes of creating a text-based patient record on paper, or in a word processing document; (2) Copying from the original or modified protocols into a text-based patient record on paper, or in a word processing document; (3) The use of a computerized system for items (1) and (2), provided that the protocol data is stored intact as a single text-based document, and is not stored as multiple discrete data fields.
Other than uses (1), (2), and (3) above, the CAP does not authorize any use of the Protocols in electronic medical records systems, pathology informatics systems, cancer registry computer systems, computerized databases, mappings between coding works, or any computerized system without a written license from the CAP.
The Protocols include tumor staging data used with permission of the American Joint Committee on Cancer (AJCC), Chicago, Illinois. The original source for this information is the AJCC Cancer Staging System (2020).
The CAP developed these protocols as an educational tool to assist pathologists in the useful reporting of relevant information. It did not issue the protocols for use in litigation, reimbursement, or other contexts. Nevertheless, the CAP recognizes that the protocols might be used by hospitals, attorneys, payers, and others. Indeed, effective January 1, 2004, the Commission on Cancer of the American College of Surgeons mandated the use of the required data elements of the protocols as part of its Cancer Program Standards for Approved Cancer Programs. Therefore, it becomes even more important for pathologists to familiarize themselves with these documents. At the same time, the CAP cautions that use of the protocols other than for their intended educational purpose may involve additional considerations that are beyond the scope of this document.
The inclusion of a product name or service in a CAP publication should not be construed as an endorsement of such product or service, nor is failure to include the name of a product or service to be construed as disapproval.
