While uRPF is used as an ingress filtering mechanism, it is affected by reverse-path forwarding. Reverse path filters are typically used to disable asymmetric routing where an IP application has a different incoming and outgoing routing path. Its intent is to prevent a packet entering one interface from leaving via the other interfaces. Reverse ...
Controlled flooding has its own two algorithms to make it reliable, SNCF (Sequence Number Controlled Flooding) and RPF (reverse-path forwarding). In SNCF, the node attaches its own address and sequence number to the packet, since every node has a memory of addresses and sequence numbers.
To implement the multicast routing, Internet Group Management Protocol (IGMP) and a multicast routing protocol (Reverse-path forwarding, PIM-SM) for registration subscriber grouping and control traffic are required for multicast transmission. [2] [3] [4] Regarding IP multicast, it is a technique for one-to-many communication over an IP network ...
The term reverse-path forwarding is used to describe this concept of routing packets away from the source, rather than towards the destination. A number of errors can happen if packets intended for unicast are accidentally sent to a multicast address; in particular, sending ICMP packets to a multicast address has been used in the context of DoS ...
PIM uses the unicast routing table for reverse-path forwarding. [1]: 56–57 There are four variants of PIM: PIM Sparse Mode (PIM-SM) explicitly builds unidirectional shared trees rooted at a rendezvous point (RP) per group, and optionally creates shortest-path trees per source. PIM-SM generally scales fairly well for wide-area usage. [2] [3]
Perfect forwarding, a feature of the programming language C++11; Port forwarding, the act of forwarding a network port from one network node to another; Reverse-path forwarding, a technique used in routers for ensuring loop-free forwarding of packets in multicast routing and to help prevent IP address spoofing in unicast routing
The more complex case is a Decorator Pattern that by using interfaces, forwarding can be made more flexible and typesafe. "Flexibility" here means that C need not refer to A or B in any way, as the switching of forwarding is abstracted from C. In this example, class C can forward to any class that implements an interface I.
Topology broadcast based on reverse-path forwarding (TBRPF) is a link-state routing protocol for wireless mesh networks. The obvious design for a wireless link-state protocol (such as the optimized link-state routing protocol) transmits large amounts of routing data, and this limits the utility of a link-state protocol when the network is made of moving nodes.
