    Abstract: A method, system and computer program product. The method includes: receiving multiple variable bit rate version of a program; wherein different variable bit rate versions of the program differ from each other by their bit rate; converting each variable bit version of the program to a constant bit version of the program by adding null packets so that once an edge device removes the null packets a valid single program transport stream is generated; and transmitting multiple constant bit versions of the program to a server.

    Abstract: A non-transitory computer readable medium and a method for session based classification. The method may include detecting an initialization of a certain TCP connection; defining the certain TCP connection as an active TCP connection; receiving, by a classifier, an incoming packet that belongs to a session that involves conveying a media asset using a HTTP as an application layer protocol; determining, by the classifier, whether the incoming packet belongs to the certain active TCP connection or not; and if it is determined that the incoming packet belongs to the certain active TCP connection then classifying the incoming to a session that is associated with the certain active TCP connection based upon a mapping between sessions and active TCP connections.
