Remote Procedure Call Protocol

A Remote Procedure Call Protocol is a network protocol that enables distributed systems to request execution of procedures on remote systems.

• Context:
  • It can establish Cross-System Communication through standardized formats.
  • It can enable Remote Execution through procedure invocations.
  • It can support Data Serialization through message encodings.
  • It can maintain Network Transport through connection protocols.
  • It can handle Error States through failure handling mechanisms.
  • ...
  • It can often implement Session Management through connection tracking.
  • It can often provide Security Controls through authentication mechanisms.
  • It can often facilitate Load Distribution through server routing.
  • It can often support Version Compatibility through protocol negotiation.
  • ...
  • It can range from being a Simple Point-to-Point Protocol to being a Complex Distributed System Protocol, depending on its architectural scope.
  • It can range from being a Basic Request-Response Protocol to being an Advanced Integration Protocol, depending on its feature set.
  • ...
  • It can integrate with Network Layer for transport handling.
  • It can connect to Service Layer for procedure execution.
  • It can support Security Layer for access control.
  • ...
• Example(s):
  • Encoding-Based Protocols, such as:
    • Binary Protocols, such as:
      • gRPC for high-performance communication.
      • Protocol Buffers for efficient data transfer.
    • Text Protocols, such as:
      • JSON-RPC for web-based integration.
      • XML-RPC for enterprise systems.
  • Transport-Based Protocols, such as:
    • HTTP-Based Protocols, such as:
      • REST RPC for web services.
      • SOAP for enterprise services.
    • TCP-Based Protocols, such as:
      • DCOM for windows systems.
      • Java RMI for java platforms.
  • ...
• Counter-Example(s):
  • Message Queue Protocol, which uses message brokers instead of direct invocation.
  • Shared Memory Protocol, which uses local memory instead of network transport.
  • File Transfer Protocol, which transfers files instead of executing procedures.
