Multicast features
A multicast group is a multicast receiver set identified by an IP multicast address. A multicast source is an information sender. The group memberships are dynamic. Multicast routers or Layer 3 multicast devices are routers or Layer 3 switches that support Layer 3 multicast.
What is the characteristics of multicast transmission?
Characteristics of multicasting are as follows: Designed to handle traffic destined to multiple hosts. Multicast traffic establishes a one-to-many type of transmission, sending one stream of traffic to each requesting broadcast domain. The IP address that defines a multicast group is a Class D address (224.0.
What are three private IPv4 address choose three?
The designated private IP addresses are within the three IP address ranges: 10.0. 0.0 – 10.255. 255.255.
What are the characteristics of reliable multicast?
Reliable Multicast Messaging
High delivery performance. Implementation of a message delivery system. Fast message filtering. A number of degrees of reliability above the standard IP multicast. Multicast stream failover. A number of different policies for congestion and traffic control.
Which three pieces of information are revealed by the ipconfig command without the all switch )? Choose three?
This includes the IP address; the subnet mask and the default gateway addresses.
Which address prefix range is reserved for IPv4 multicast?
Multicast IPv4 addresses use the reserved class D address range of 224.0. 0.0 to 239.255. 255.255.
What are addresses in the 224.0 0.0 range used for?
The range of addresses between 224.0. 0.0 and 224.0. 0.255, inclusive, is reserved for the use of routing protocols and other low-level topology discovery or maintenance protocols, such as gateway discovery and group membership reporting.
What are the types of ordering in multicast?
Ordered Multicast
FIFO ordering: If a correct process issues multicast(g,m) and then multicast(g,m’), then every correct process that delivers m’ will have already delivered m. Causal ordering: If multicast(g,m) → multicast(g,m’) then any correct process that delivers m’ will have already delivered m.
What are the properties of reliable multicast in distributed systems?
A reliable multicast protocol imposes no restriction on the order in which messages are delivered to group processes. Given that multicasts may be in progress by a number of originators simultaneously, the messages may arrive at different processes in a group in different orders.
What is basic multicast?
Basic multicast refers to multicasting at the link layer or below. In the case of Ethernet, any frame where the least significant bit of the first byte of the destination address are sent to all nodes in the network.
Which three pieces of information are identified by a URL?
Which three pieces of information are identified by a URL? (Choose three.) Explanation: URLs are used to access specific content on a web server through a web browser. The URL identifies the protocol that is being used such as HTTP or FTP, the domain of the server, and the location of the resource on the server.
