Framing and it's types

In the above link you can check all the information about framing in detail. 

Framing

To service the network layer, data link layer uses the service provided to it by the physical layer. Physical layer accepts the raw bit stream and delivers it to destination. This bit stream may contain error i.e., number of bits received may not be equal to number of bits transmitted. various simple methods used for framing are-

  • a)        Character count
  • b)      Starting and ending character, with character stuffing
  • c)       Starting and ending flags, with bit stuffing.

The different types of framing protocols are as follows:-

  • 1)      Character-oriented Protocols
  • 2)      Bit-oriented protocols



1)      Character-oriented Protocols

The format of a frame in a character-oriented protocol . Data to be carried are 8-bit characters from a coding system like ASCII in a character-oriented protocol. 

2)      Bit-oriented protocols

The data section of a frame is a bits sequence to be interpreted by the upper layer as text, graphic, audio, video, and so on in a bit-oriented protocol. Although, in addition to headers (and possible trailers), we still required a delimiter to separate one frame from the other.

Protocol verification using finite state machine model in computer network

By Kajal Vishwakarma -
Protocol Verification Using Finite State Machine Model:- The finite state machine is a mainly used in several protocol models with this technique, every protocol machine is always in a particular state at every time instant. Variables, including the program counter. From every state, there are zero or more possible transition to other states. When some event happens, transition take place. In case of a protocol machine, a transition might take place if a frame is transmitted, if a frame arrives, if a timer expires, if an interrupt takes place, etc. One particular state is designated as the initial state. This state corresponds to the description of the system when it starts running, or at some convenient starting place shortly thereafter. From the initial state, some, perhaps all, of the other states may be approached by a sequence of transition. this technique is called reachability analysis. This analysis can be helpful in determining whether a protocol is correct. All processes are
