MIME media type name : Application

MIME subtype name : Vendor Tree - vnd.gridmp

Required parameters : none

Optional parameters : none

Encoding considerations : binary
This media type may require encoding on transports not capable of 
handling binary.

Security considerations :

This is a proprietary data format used solely by the UD Grid MP
product between the MP Agent and the Grid MP services.

The body of any request using this MIME type contains an encrypted 
and digitially-signed message that is prepared by the client. The 
response from the server also uses this MIME type and is also 
encrypted and digitally-signed. The security policies and digital keys
used to authenticate the network communication are configurable
by the user at the time of installation.

The Grid MP Agent uses the data encrypted communications to receive
instructions regarding what programs and data files should be
executed on the grid node. Role-based access control on the server
authenticates any users that wish to send jobs or instructions to
the MP Agent.

Actual executable programs or data files are not actually transmitted
using this protocol; instead, remote references included within this
protocol specify the digital hash (currently SHA1) of the file(s) that
are needed to execute the program. The MP Agent searches its local
file cache for an identical hash and executes the program with the
requested arguments. File hashes that are not already cached can be
automatically downloaded from a Grid MP File Service using a separate
authenticated HTTP/SSL protocol that is not described here.


Interoperability considerations :

This is a proprietary data format used solely by the UD Grid MP 
product between the MP Agent and the Grid MP services.
