   hello
   
   The disadvantage is that OSI model does not cover all aspects of data communication
   
       * Due to the complexity of the system poor performance is obtained, especially in some real time applications.
       * Direct substitution of layers is not always possible e.g. if a LAN with broadcast capability is inserted below a network protocol that did not support this facility, then this service would be lost to the upper layers.
       * Although protecting equipment from becoming obsolete it simultaneously hinders technological advancement.
   
   hope it helps
