Round-robin DNS is a technique of load distribution, load balancing, or fault-tolerance provisioning multiple, redundant Internet Protocol service hosts, e.g., Web server, FTP servers, by managing the Domain Name System's (DNS) responses to address requests from client computers according to an appropriate statistical model.
Round-robin DNS is an alternate method of load balancing that does not require a dedicated software or hardware node. In this technique, multiple IP addresses are associated with a single domain name; clients are given IP in a round-robin fashion. IP is assigned to clients with a short expiration so the client is more likely to use a different ...
Weighted round robin (WRR) is a network scheduler for data flows, but also used to schedule processes. Weighted round robin [ 1 ] is a generalisation of round-robin scheduling . It serves a set of queues or tasks.
Network load balancing is the ability to balance traffic across two or more WAN links without using complex routing protocols like BGP.. This capability balances network sessions like Web, email, etc. over multiple connections in order to spread out the amount of bandwidth used by each LAN user, thus increasing the total amount of bandwidth available.
If a service has multiple SRV records with the same priority value, clients should load balance them in proportion to the values of their weight fields. In the following example, both the priority and weight fields are used to provide a combination of load balancing and backup service.
The characteristic payload information of an MX record [1] is a preference value (above labelled "Priority"), and the domain name of a mailserver ("Host" above).. The priority field identifies which mailserver should be preferred - in this case the values are both 10, so mail would be expected to flow evenly to both onemail.example.com and twomail.example.com - a common configuration.
RRDtool (round-robin database tool) aims to handle time series data such as network bandwidth, temperatures or CPU load. The data is stored in a circular buffer based database, thus the system storage footprint remains constant over time. It also includes tools to extract round-robin data in a graphical format, for which it was originally intended.
Thus, by default, load balancing is not based on traffic load, but rather on the number of hosts that will use each gateway router. By default, GLBP load balances in round-robin fashion. GLBP elects one AVG (Active Virtual Gateway) for each group. Other group members act as backup in case of AVG failure.
