Wat doet een dlc/llc protocol?

[rammes]

tja ik ben dus nieuwschierig waar die voor gebruikt word.

[Verwijderd]

Het DLC/LLC protocol gebruik je onderandere onder NT om printers ( HP ) rechtstreeks op LAN HW adress te koppelen .
Dit is b.v. heel handig met externe printservers ( HP jetdirect).

Dan hoef je tenminste niet die HP jetadmin SW te instaleren.

Mocht je nog uitleg willen hebben over hoe dit te doen mail me dan ff

Waar het protocol verder nog voor wordt gebruikt weet ik zo gauw niet maar er zullen vast nog meet toepassingen zijn die het gebruiken .

p.s. Hoelang ben je al systeembeheerder ?

Data Link Control

DLC also is an abbreviation for digital loop carrier.
DLC (Data Link Control) is the service provided by the Data Link Layer of function defined in the Open Systems Interconnection (OSI) model for network communication. The Data Link Layer is responsible for providing reliable data transfer across one physical link (or telecommunications path) within the network. Some of its primary functions include defining frame, performing error detection or ECC on those frames, and performing flow control (to prevent a fast sender from overwhelming a slow receiver).

Many point-to-point protocols exist at the Data Link Layer including High-level Data Link Control (High-Level Data Link Control), Synchronous Data Link Control (Synchronous Data Link Control), Link Access Procedure Balanced (LAPB), and Advanced Data Communications Control Procedure (ADCCP). All of these protocols are very similar in nature and are found in older networks (such as X.25 networks). In the Internet, one of two point-to-point protocols are used at this layer: Serial Line Internet Protocol (Serial Line Internet Protocol) or Point-to-Point Protocol (Point-to-Point Protocol) with PPP being the newer, approved standard. All of these protocols are used in point-to-point connections such as those on Metropolitan Area Network (MAN) or Wide Area Network (wide area network) backbone or when we dial our Internet service provider (Internet service provider) from home using a modem.

In local area networks () where connections are multipoint rather than point-to-point and require more line-sharing management, the Data Link Layer is divided into two sublayers: the Logical Link Control (LLC) sublayer and the Media Access Control (MAC address) sublayer. The LLC protocol performs many of the same functions as the point-to-point data link control protocols described above. The MAC protocols support methods of sharing the line among a number of computers. Among the most widely used MAC protocols are Ethernet (IEEE 802.3), Token Bus (IEEE 802.4), and token ring (IEEE 802.5) and their derivatives.

en SDLC is:

Synchronous Data Link Control

SDLC (Synchronous Data Link Control) is a transmission protocol developed by IBM in the 1970s as a replacement for its binary synchronous (BSC) protocol. SDLC is equivalent to layer 2 of the OSI (Open Systems Interconnection) model of network communication. This level of protocol makes sure that data units arrive successfully from one network point to the next and flow at the right pace.
SDLC uses the primary station-secondary station model of communication. Typically in IBM mainframe networks, the host mainframe is the primary station and workstations and other devices are secondary stations. Each secondary station has its own address. Typically, multiple devices or secondary stations are attached to a common line in what is known as a multipoint or multidrop arrangement. SDLC can also be used for point-to-point communication. SDLC is primarily for remote communication on corporate wide-area networks (wide area network).

SDLC was a basis for the International Organization for Standardization standard data link protocol, High-Level Data Link Control (High-Level Data Link Control). SDLC essentially became one of several variations of HDLC, the normal response mode (NRM). While SDLC (and normal response mode) are efficient protocols for closed private networks with dedicated lines, other modes of HDLC serve X.25 and frame relay protocols that manage packet on shared-line switched networks like those used by the Internet.

SDLC became part of IBM's Systems Network Architecture (Systems Network Architecture) and the more comprehensive Systems Application Architecture (Systems Application Architechture) and its more recent Open Blueprint. SDLC is still a commonly encountered and probably the prevalent data link protocol in today's mainframe environment.

bedankt voor de info, de rede dat ik dit vraag is dat we een probleem hebben met as400 printen op die hp printers. die timedout elke keer.. iemand daar ervaring mee>? kan ik dat oplossen met dlc/llc?

Mail me ff op [e-mail] hoe jullie nu een printerqueue aanmaken dan zal ik ff zien of ik kan helpen .
