FIELD: communication.
SUBSTANCE: invention relates to systems and methods of digital communication. Method involves: receiving data unit from content provider; generation of reference key from data unit; determining if reference key exists in cache, where stored previously saved reference keys; if reference key exists in the cache, transmitting reference key using transit communication channel in communication device with asymmetric cache in relation to cache; and if reference key does not exist in cache, generation of new reference key, corresponding to unit of data, preservation of new reference key in cache and transfer of new reference switch and data unit by transit communication channel in communication device with asymmetric cache in relation to cash.
EFFECT: technical result consists in faster data transmission in network.
