Network assisted multicast may be implemented at the data link layer using one-to-many addressing and switching such as Ethernet multicast addressing, Asynchronous Transfer Mode (ATM), point-to-multipoint virtual circuits (P2MP) [4] or InfiniBand multicast. Network-assisted multicast may also be implemented at the Internet layer using IP multicast.
Multicast DNS (mDNS) is a computer networking protocol that resolves hostnames to IP addresses within small networks that do not include a local name server.It is a zero-configuration service, using essentially the same programming interfaces, packet formats and operating semantics as unicast Domain Name System (DNS).
Multicast is the most common approach, and each VXLAN network identifier (VNI) is mapped to a single multicast group, while each multicast group may map to one or more VNIs. When a VTEP comes alive it uses the Internet Group Management Protocol to join the multicast groups for the VNIs it uses. When a VTEP has to send BUM traffic it will send ...
In computer networking, unicast is a one-to-one transmission from one point in the network to another point; that is, one sender and one receiver, each identified by a network address. [ 1 ] Unicast is in contrast to multicast and broadcast which are one-to-many transmissions.
On the local network, multicast delivery is controlled by IGMP (on IPv4 network) and MLD (on IPv6 network); inside a routing domain, PIM or MOSPF are used; between routing domains, one uses inter-domain multicast routing protocols, such as MBGP. The following are some common delivery and routing protocols used for multicast distribution:
The Link-Local Multicast Name Resolution (LLMNR) is a protocol based on the Domain Name System (DNS) packet format that allows both IPv4 and IPv6 hosts to perform name resolution for hosts on the same local link. It is included in Windows Vista, Windows Server 2008, Windows 7, Windows 8, Windows 10. [1]
A multicast address is a logical identifier for a group of hosts in a computer network that are available to process datagrams or frames intended to be multicast for a designated network service. Multicast addressing can be used in the link layer (layer 2 in the OSI model ), such as Ethernet multicast, and at the internet layer (layer 3 for OSI ...
It is also a concept used in Queueing Network Analyzers (QNAs) or in packet tracing. Applied to Internet routers, a flow may be a host-to-host communication path, or a socket-to-socket communication identified by a unique combination of source and destination addresses and port numbers, together with transport protocol (for example, UDP or TCP).
