2.1 Transport

  • Article

The Virtual Disk Service Remote Protocol uses the DCOM Remote Protocol, as specified in [MS-DCOM], as its transport. On its behalf, the DCOM Remote Protocol uses the following RPC protocol sequence: RPC over TCP, as defined in [MS-RPCE].

To access an interface, the client requests a DCOM connection to its object UUID endpoint on the server, as specified in section 1.9.

The RPC version number for all interfaces is 0.0.

An implementation of the Virtual Disk Service Remote Protocol MUST configure its DCOM implementation or underlying RPC transport with the RPC_C_AUTHN_LEVEL_PKT_PRIVACY security parameter.<4>

The Virtual Disk Service Remote Protocol interfaces make use of the underlying DCOM security framework, as specified in [MS-DCOM], and rely on it for access control. DCOM differentiates between launch and access. An implementation of the Virtual Disk Service Remote Protocol MAY differentiate between launch and access permission, and MAY impose different authorization requirements for each interface.<5>
