![]() ![]() Simvastatin serves as a 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) inhibitor, with prolonged use proven to cause side effects. Information Frame Controls: Information Frame controls the sequence in which the frames are being sent and number the frames.Hyperlipidemia is generally managed with statin-based drugs. SDLC Features There are many features that contribute to the functionality of the SDLC frame work.įlag: The flag feature is used by the SDLC format to initiate and terminate the errors by keeping them under a check.Īddress: The SDLC address feature helps identify if the frames are being received from the primary or the secondary because it contains information of group address, specific address, broadcast address and so on. Loop nodes where the first node which is the primary is connected to the secondary nodes and has two nodes on either side. Multipoint where there is one primary node and the remaining are all secondary nodes. However there are some basic configurations that are followed by these nodes like Point to Point in which there are only two nodes, one is the primary and the other is the secondary. The secondary nodes actually send all the data that is received to the primary node. ![]() The primary node is responsible for handling all the secondary nodes and controls all the links. The SDLC protocol simplifies the data control process into a basic pattern. Like for example point to point links, multi links, switched networks and packet networks and many more. SDLC Protocols and Topologies The SDLC protocol supports a vast variety of topologies and types of data links. Here the basic ingredient is the SDLC which is important in the entire layering and data transfer process as it is the primary protocol that is being used. There are different types of layers and each of these layers has its own functionality which is some what similar to the OSI layers.įor example the data is transferred without errors form the Data Link Control layer to the Network Addressable Units or the NAUs using the SDLC or the synchronous data link control protocol.ĭata progresses from the higher layers to the lower layers and is eventually transferred to the communication ports. In this system all the functions in a network can be defined and slotted into layers. It is basically a linked layer protocol which can be used with systems network architecture or the SNA environment. The information field or user data field carries the data and is of variable length. The address field and control field serve the same purpose as discussed in HDLC and are of 8 bit each. ![]()
