The STP protocol allows switches to have redundant connections, while avoiding problems associated with switching loops. For example, if there is a switching loop, a broadcast would go around in circles indefinitely. There are other problems, too. The STP protocol disables enough connections so that there are no loops; the disabled connections are in "stand-by" and can be enabled again when other connections fail, thus providing the desired redundancy.
A SIP is a signaling communications protocol widely used for controlling multimedia communication sessions such as voice or video calling. The SIP2 is the second version of this protocol.
Signaling protocols are sets of rules and procedures used to establish, maintain, and terminate communication sessions in networks. They facilitate the exchange of control messages between devices, enabling them to negotiate parameters, manage resources, and ensure reliable data transfer. Common examples include SIP (Session Initiation Protocol) for voice over IP and SS7 (Signaling System No. 7) for traditional telephony networks. These protocols are essential for managing call setup, signaling, and connection control in various communication systems.
