Multicast lightpaths protection refers to the network's prompt response to reroute traffic onto an alternative path in the event of a failure. In a dedicated backup path, resources are exclusively allocated to a single connection and not shared with other connections along the backup path.
The Resource Reservation Protocol (RSVP) is a transport layer [1] protocol designed to reserve resources across a network using the integrated services model. RSVP operates over an IPv4 or IPv6 and provides receiver-initiated setup of resource reservations for multicast or unicast data flows.
It is Core-Based Tree, selecting one router in the network as the root and transmitting information through the root router. Maximum delay in the tree is longer than SBT(Source-based tree), The core router manages all the information, and the remaining routers manage the direction of the core and the multicast information requested by the current neighboring router. it has a Good Scalability ...
Adaptive multicast strategies were developed, allowing networks to dynamically adjust their behavior based on real-time data about congestion, bandwidth availability, and device requirements. [2] 2020s: SMART Multicast has become critical in emerging technologies like 5G, edge computing, and autonomous systems. Enhanced with AI and machine ...
UPnP logo as promoted by the UPnP Forum (2001–2016) and Open Connectivity Foundation (2016–present). Universal Plug and Play (UPnP) is a set of networking protocols on the Internet Protocol (IP) that permits networked devices, such as personal computers, printers, Internet gateways, Wi-Fi access points and mobile devices, to seamlessly discover each other's presence on the network and ...
The Internet Group Management Protocol (IGMP) is a communications protocol used by hosts and adjacent routers on IPv4 networks to establish multicast group memberships. IGMP is an integral part of IP multicast and allows the network to direct multicast transmissions only to hosts that have requested them.
The multicast tree construction is receiver driven and is initiated by network nodes that are close to the receivers. IP multicast scales to a large receiver population. The IP multicast model has been described by Internet architect Dave Clark as, "You put packets in at one end, and the network conspires to deliver them to anyone who asks." [5]
In computer networking, multicast is a type of group communication where data transmission is addressed to a group of destination computers simultaneously. [1] Multicast can be one-to-many or many-to-many distribution. [2] [3] Multicast differs from physical layer point-to-multipoint communication.
