The server was acting as a gateway or proxy and received an invalid response from the upstream server. 503 Service Unavailable The server cannot handle the request (because it is overloaded or down for maintenance). Generally, this is a temporary state. [26] 504 Gateway Timeout
In distributed computing, a remote procedure call (RPC) is when a computer program causes a procedure (subroutine) to execute in a different address space (commonly on another computer on a shared computer network), which is written as if it were a normal (local) procedure call, without the programmer explicitly writing the details for the remote interaction.
DCE/RPC, short for "Distributed Computing Environment / Remote Procedure Calls", is the remote procedure call system developed for the Distributed Computing Environment (DCE). This system allows programmers to write distributed software as if it were all working on the same computer, without having to worry about the underlying network code.
Sound servers appeared in Unix-like operating systems after limitations in Open Sound System were recognized. OSS is a basic sound interface that was incapable of playing multiple streams simultaneously, dealing with multiple sound cards, or streaming sound over the network. A sound server can provide these features by running as a daemon. It ...
RPC results (<rpc-reply> messages), and; event notifications (<notification> messages). Every NETCONF message is a well-formed XML document. An RPC result is linked to an RPC invocation by a message-id attribute. NETCONF messages can be pipelined, i.e., a client can invoke multiple RPCs without having to wait for RPC result messages first.
At a higher level, the RTMP encapsulates MP3 or AAC audio and FLV1 video multimedia streams, and can make remote procedure calls (RPCs) using the Action Message Format. Any RPC services required are made asynchronously, using a single client/server request/response model, such that real-time communication is not required. [clarification needed ...
Microsoft RPC (Microsoft Remote Procedure Call) is a modified version of DCE/RPC. Additions include partial support for UCS-2 (but not Unicode ) strings, implicit handles, and complex calculations in the variable-length string and structure paradigms already present in DCE/RPC.
The main purpose of an RPC is to allow a local computer to invoke procedures on a remote computer . Since the client and server have different address spaces, the parameters used in a function call must be converted. Otherwise, the parameter values would be unusable because pointers to parameters in one computer's memory would reference ...
