Embodiments described herein are based on the principle that shells execute commands as units of characters sent within a message. Accordingly, embodiments herein provide for establishing a remote processing session for commands by using a binding mechanism that binds a series of commands to a remote shell using a message rather than a binary stream of data. More specifically, embodiments herein provided for a mechanism of encapsulating both a command and a binding mechanism (e.g., a shell identifier and/or shell token) into a single message. Accordingly, the binding mechanism can be used throughout the lifetime of the session and allows for modeling the shell processor session (its lifetime) as a series of commands, rather than as a series of characters. In addition, note that because the binding mechanism for the shell sessions is sent within messages, the problems associated with binary or character-by-character establishment of current shell sessions are overcome.
