The Session Description Protocol (SDP) is a format for describing multimedia communication sessions for the purposes of announcement and invitation. [1] Its predominant use is in support of streaming media applications, such as voice over IP (VoIP) and video conferencing. SDP does not deliver any media streams itself but is used between ...
SDP uses various RDMA network features for high-performance zero-copy data transfers. SDP is a pure wire-protocol level specification and does not go into any socket API or implementation specifics. The purpose of the Sockets Direct Protocol is to provide an RDMA-accelerated alternative to the TCP protocol on IP. The goal is to do this in a ...
Identity and Information Management: In order to specify or design a SDP we must determine what the customer and device service dimensions are. If the SDP design needs to accommodate, say, 1m users as well as manage their devices and each identified item requires 5 to 10 information objects, the core SDP is probably dealing 20m objects in real ...
Service discovery protocol, a type of service discovery for network services; Session Description Protocol, a communication protocol for describing multimedia sessions; Single-dealer platform, software used in financial trading; Sockets Direct Protocol, a low-level remote-computing protocol
These tools have capabilities in common with drawing tools and network monitoring tools. They are more specialized than general drawing tools and provide network engineers and IT systems administrators a higher level of automation and the ability to develop more detailed network topologies and diagrams.

An application instantiates the session with the Session Description Protocol (SDP) over Session Initiation Protocol (SIP) or other rendezvous methods. The MSRP protocol is defined in RFC 4975. [1] MSRP messages can also be transmitted by using intermediaries peers, by using the relay extensions defined in RFC 4976. [2]
Announcement data is sent using IP multicast and the User Datagram Protocol (UDP). Under SAP, senders periodically transmit SDP descriptions to a well-known multicast address and port number (9875). [1] A listening application constructs a guide of all advertised multicast sessions. SAP was published by the IETF as RFC 2974. [2]
