What is the role of the logical link control sublayer?

Let us discuss the role of the logical link control sublayer. The IEEE 802.3 standard will describe the functions of the Logical link sublayer. In the OSI model, we have already discussed it as it consists of 7 layers. The logical link control sublayer is at the upper set of the data link layer. The Data link layer consists of two sublayers. The logical link layer and the other one is the Media access control layer. It is used to share the different methods of accessing the medium access layer.

All these methods are defined by 802.3 .4 .5 standards. The key role of the logical link control sublayer provides the services that are at the network layer. The logical link control provides the SAP service access points and supports the network layer. The logical link control(LLC) again receives services to the in turn from the other like its lower media access control sublevel. The below mentioned are the services that are provided by the logical link sublayer.

  • One Station sends the data in the form of frames to the other work stations without waiting for the confirmations from the destination address.
  • It doesn’t establish a connection between the two stations and will not end the connection during the end of the communication.
  • During the transmission of the data, if the data get lost, then the frames are not get retrieved back.
  • It is most fitting for media communication, and only allows the minimum delay during communication between the stations.
  • The logical link control has a very low error rate services.
  • No connection is established between the two stations before the transmission takes place.
  • These services are mainly applied for a point to point connection.
  • the connection Oriented service is provided before starting communication between the two workstations.
