Alcatel-Lucent OmniAccess Stellar Access Point Broadcast and Multicast Optimisation

Multicast and broadcast are transmission modes used to send data to multiple recipients at the same time, but they have significant differences: - Broadcast sends data to all machines on the network, while multicast sends data to a selected group of machines - Multicast is more efficient than broadcast because it avoids saturating the network with copies of identical data. Instead, the data is sent only once to a select group of machines. However, there are challenges associated with the extensive use of multicast and broadcast in wireless networks. Here are some of the main problems: - Bandwidth consumption: Multicast and broadcast can consume a large amount of bandwidth on the network, especially if many devices are connected to the network. This can lead to network saturation and decreased performance. - Latency: Extensive use of multicast and broadcast can also lead to increased latency on the network, as many copies of data are sent to multiple recipients simultaneously - Power Usage: Receiving multicast and broadcast can also result in increased power usage on wireless devices, which can impact battery life - Security: Multicast and broadcast can also pose security concerns, as they can be easily intercepted and exploited by malicious individuals This Application Note is designed to help users overcome these issues. Users will discover multiple techniques to improve network efficiency through explanations of features and recommendations.
