Define the role of Distributed Component Object Model (DCOM), CORBA and Remote Method Invocation (RMI), in distributed processing.
DCOM enables component applications to operate across the Internet
Speeding development
Lowering integration costs
Improving deployment flexibility
Cobra
COBRA owned by Object Management Group OMG is middleware
CORBA Interface Definition Language IDL provides the language- and
OS-neutral inter-object commication it supports the construction and
integration of object-oriented software components in mixed
distributed environments. object request broker
Cobra’s client to object implementation
Remote Method Invocation
RMI provides ORB functionality that is fully integrated with the Java language and runtime environment. Unlike CORBA, however, the RMI
ORB is fully integrated with the Java language and runtime environment.
Cobra vs RMI
B) Describe how web services are used to integrate disparate applications in an organization: for example, describe the role of the WSDL Web Service Definition Language, SOAP Simple Object Access Protocol, and UDDI Universal Description, Discovery and Integration ,architectures in creating and using web services.
WSDL ( Web Service Definition Language)
WSDL is a document written in XML. The document describes a Web service. It specifies the location of the service and the operations (or methods) the service exposes.
Web service as collections of network endpoints or ports
Messages are abstract descriptions of data being exchanged
Port types are abstraction collection of operations
Concrete protocol and data format specification for a particular port type constitutes a binding
SOAP
SOAP is an XML based protocol for accessing Web Services.
SOAP stands for Simple Object Access Protocol
SOAP simply a procedural call
SOAP is a stateless protocol
SOAP Body

UDDI (Universal Description, Discovery and Integration)
UDDI is a platform-independent framework for describing services.
It’s a directory service where companies are in search of web services.
UDDI uses WSDL to describe interfaces to web services
SOAP, WSDL and UDDI together make systems flexible
Together is more of a declarative type of programming
UDDI working with WSDL AND SOAP
C) Describe the role of socket programming in communicating between systems and
contrast the protocols and uses of TCP/IP sockets and Datagram sockets.
A socket is one of the most fundamental technologies of computer networking. Sockets allow applications to communicate using standard mechanisms built into network hardware and operating systems.
Three socket types are available:
Stream sockets provide a bidirectional, reliab ...

RCS Hub - Driving global interconnectivity for RCS Openmind Networks
As mobile messaging evolves to offer rich communications, there is a key requirement for an RCS Interconnect Hub as identified by the GSMA with their recent RFI. Openmind's White Paper describes the architecture and features of an RCS Interconnect Hub and discusses future interworking possibilities.

30. MM1: submission request (1/2) O 1.0 Request for a delivery report. This parameter indicates whether or not delivery report(s) are to be generated for the submitted message. Two values can be assigned to this parameter: 'yes' (delivery report is to be generated) or 'no' (no delivery report requested). If the message class is 'auto', then this parameter is present in the submission PDU and is set to 'no'. X-Mms-Delivery-Report O 1.0 Visibility of the sender address. This parameter is either set to 'show' (default) for showing the sender address to recipient(s) or 'hide' for hiding the sender address to recipient(s). From MMS 1.2, 'show' is not anymore the default value for this parameter. If this parameter is not present in an MMS 1.2 PDU, then network preferences for the sender anonymity feature are used.

Other classes can also be defined in the form of text strings. X-Mms-Message-Class O 1.0 A short textual description for the message. Subject O 1.0 One or multiple addresses (phone number or email address) for message recipient(s). Secondary recipients / blind copy. Bcc O 1.0 One or multiple addresses (phone number or email address) for message recipient(s). Secondary recipients. Cc O 1.0 One or multiple addresses (phone number or email address) for message recipient(s). Primary recipients.

31. MM1: submission request (2/2) 1.0 Content type of the multimedia message. (e.g. application/vnd.wap.multipart.related ). Content-Type 1.2 MMBox message flag – This parameter indicates the list of flags associated to a message stored in the MMBox (considered only if X-Mms-Store is set to 'yes'). X-Mms-MM-Flags 1.2 MMBox message state – When X-Mms-Store is set to 'yes', this parameter indicates the message state in the originator's MMBox (e.g. sent, draft, etc.). If X-Mms-Store is set to 'yes' and if this parameter is not present then the message default state is 'sent'. X-Mms-MM-State 1.2 MMBox storage request - This parameter indicates whether the originator MMS client requests to save the message in the originator's MMBox in addition from sending it.

This parameter specifies the latest time for the recipient(s) to submit a message reply. This parameter is only present in the PDU if reply charging is requested. X-Mms-Reply-Charging-Deadline 1.1 Request for reply charging. The presence of this parameter indicates that reply charging is requested by the message originator. Two values can be assigned to this parameter: 'requested' when the originator is willing to pay for the message reply(s) or 'requested text only' when the originator is willing to pay for message reply(s) containing text only. In any case, two parameters (reply message size and reply deadline) specify conditions for the message reply to be paid for by the originator. X-Mms-Reply-Charging 1.0 Request for a read report. This parameter indicates whether or not read reports are to be generated for the message.
