RPC In terms of the extensions it added to COM DCOM had to solve the problems of Marshalling serializing and deserializing the arguments and return val ues of method calls over the wire Distributed garbage collection ensuring that references held by clients of interfaces are released when for example the client process crashed or the network connection was lost One of the key factors in solving these problems is the use of DCE RPC as the underlying RPC mechanism behind DCOM DCE RPC has strictly defined rules regarding marshalling and who is responsible for freeing memory DCOM was a major competitor to CORBA Proponents of both of these technologies saw them as one day becoming the model for code and service reuse over the Internet However the difficulties involved in get ting either of these technologies to work over Internet firewalls and on unknown and insecure machines meant that normal HTTP requests in combination with web browsers won out over both of them Microsoft at one point attempted and failed to head this off by adding an extra http transport to DCE RPC called DTD Can accompany a document essentially defining the rules of the docu ment such as which elements are present and the structural relationship between the elements It defines what tags can go in a XML document what tags can contain other tags the number and sequence of the tags the attributes a tag can have and optionally the values tho
