GTM distributes DNS name resolution requests to the virtual In a particular geographic region to a data center or server located in that Use Topology when you want to send requests from a client Information derived from the DNS message to the topology records in a topology BIG-IP GTM determines the proximity of the resource by comparing location LDNS to resolve to a specific virtual server.īIG-IP GTM distributes DNS name resolution requests using proximity-based loadīalancing. Use Static Persist when you want requests from a specific Then BIG-IP GTM again resolves requests to that virtual server. Requests to another virtual server until the original virtual server becomesĪvailable. However, when the selected virtual server becomes unavailable, BIG-IP GTM sends Is passing traffic to the system taking into account the specified CIDR of the LDNS.Įach LDNS (and thus each client) generally resolves to the same virtual server Hash algorithm orders the virtual servers in the list differently for each LDNS that Virtual server in a pool using the persist mask with the source IP address of the LDNSĪnd a hash algorithm to determine the order of the virtual servers in the list. Use Round Robin when you want to distribute requestsĮqually among all virtual servers in a pool. Over time each virtual server receives an

You can also use Return to DNS when you want Use Return to DNS when you want to temporarily remove a To a fast server and half as many connections to a slow server.īIG-IP GTM immediately distributes DNS name resolution requests to an LDNS for Use Ratio when you want to send twice as many connections Several resources based on a priority level or weight assigned to each resource. Robin, a load balancing pattern in which requests are distributed among If the preferred loadīalancing method fails, GTM offers the next pool in a load balancing response.īIG-IP GTM distributes DNS name resolution requests among the virtual servers inĪ pool or among pools in a multiple pool configuration using weighted round Want to limit each pool to a single load balancing method. Use None for the alternate and fallback methods when you If all pools are unavailable, BIG-IP GTM returns an aggregate of the IP addresses ofĪll the virtual servers in the pool using BIND.
