508 Loop Detected (WebDAV; RFC 5842) The server detected an infinite loop while processing the request (sent instead of 208 Already Reported). 510 Not Extended (RFC 2774) Further extensions to the request are required for the server to fulfil it. [28] 511 Network Authentication Required (RFC 6585) The client needs to authenticate to gain ...
If a SIP proxy determines a response context has insufficient Incoming Max-Breadth to carry out a desired parallel fork, and the proxy is unwilling/unable to compensate by forking serially or sending a redirect, that proxy MUST return a 440 response.
Simple Loop Prevention Protocol (SLPP) in computer networking is a data link layer protocol developed by Nortel (previously acquired by Avaya, now a part of Extreme Networks) to protect against Layer 2 network loops. SLPP uses a small hello packet to detect network loops.
A common method is to direct all World Wide Web traffic to a web server, which returns an HTTP redirect to a captive portal. [8] When a modern, Internet-enabled device first connects to a network, it sends out an HTTP request to a detection URL predefined by its vendor and expects an HTTP status code 200 OK or 204 No Content.
If one of these fibers is broken, the link has become one-way or unidirectional. The goal of the UDLD protocol is to detect a broken bidirectional link (e.g. transmitted packets do not arrive at the receiver, or the fibers are connected to different ports). For each device and for each port, a UDLD packet is sent to the port it links to.
In a simple reachability protocol, such as EGP, the routing loop will persist forever. In a naive distance-vector protocol, such as the routing information protocol, the loop will persist until the metrics for C reach infinity (the maximum number of routers that a packet can traverse in RIP is 15. The value 16 is considered infinity and the ...
URL redirection, also called URL forwarding, is a World Wide Web technique for making a web page available under more than one URL address. When a web browser attempts to open a URL that has been redirected, a page with a different URL is opened.
Loop Detect packet – not a part of RRCP protocol itself, but is closely associated, being an underlying mechanism for a simplified Spanning tree protocol substitute in RRCP-capable switch controllers. [5]
