a period, the large-IP system iterates with the listing of two topology records to locate a match.

1. A customer in New You are able to constitutes a DNS request.
2. LDNS 11.1..1 queries the large-IP system within the The United States data center.
3. The Large-IP system directs the LDNS to Pool1. To find out this answer, for every pool, one at

   a period, the large-IP system iterates with the listing of two topology records to locate a match.

   Pool1 matches the very first topology record within the list, because both LDNS request source

   (11.1..1) and also the Destination (Pool1) from the DNS request match the very first topology record

   therefore, the large-IP system assigns a score of 100 to Pool1. For Pool2, there’s no matching

   topology record which contains both LDNS request source (11.1..1) and also the Destination

   (Pool2) therefore, the large-IP system assigns a score of zero to Pool2. Pool3, matches the

   third topology record within the list, because both LDNS request source (11.1..1) and also the

   Destination (Pool3) from the DNS request match the 3rd topology record therefore, the large-IP

   system assigns a score of 10 to Pool3. The Large-IP system directs the LDNS to transmit the request

   towards the pool using the greatest score.

4. The LDNS transmits the DNS request to Pool1 within the The United States data center. The way the system

   distributes the DNS demands towards the people of Pool1 isn’t portrayed within this illustration, but

   is dependant on the burden balancing method configured for Pool1.

5. A customer in Lima constitutes a DNS request.
6. LDNS 10.1..1 queries the large-IP system within the The United States data center.
7. The Large-IP system directs the LDNS to Pool2. To find out this answer, for every pool, one at

   a period, the large-IP system iterates with the listing of two topology records to locate a match.

   For Pool1, there’s not really a matching topology record which contains both LDNS request source

   (10.1..1) and also the Destination (Pool1) therefore, the large-IP system assigns a score of zero to

   Pool1. Pool2 matches the 2nd topology record within the list, because both LDNS request

   source (10.1..1) and also the Destination (Pool2) from the DNS request match the 2nd topology

   record therefore, the large-IP system assigns a score of 100 to Pool2. Pool3, matches the 3rd

   topology record within the list, because both LDNS request source (10.1..1) and also the

   Destination (Pool3) from the DNS request match the 3rd topology record therefore, the large-IP

   system assigns a score of 10 to Pool3. The Large-IP system directs the LDNS to transmit the request

   towards the pool using the greatest score.

8. The LDNS transmits the DNS request to Pool2 within the South Usa data center. The way the system

   distributes the DNS demands towards the people of Pool2 isn’t proven within this illustration, but is

   in line with the load balancing mode configured for Pool2.

9. A customer in Chicago constitutes a DNS request.
10. LDNS 12.1..1 queries the large-IP system within the The United States data center.
11. The Large-IP system directs the LDNS to Pool3. To find out this answer, for every pool, one at

    a period, the large-IP system iterates with the listing of two topology records to locate a match.

    For Pool1, there’s not really a matching topology record which contains both LDNS request source

    (12.1..1) and also the Destination (Pool1) therefore, the large-IP system assigns a score of zero to

    Pool1. For Pool2, there’s not really a matching topology record which contains both LDNS request

    source (12.1..1) and also the Destination (Pool1) therefore, the large-IP system assigns a score of

    zero to Pool2. Pool3, matches the 3rd topology record within the list, because both LDNS

    request source (12.1..1) and also the Destination (Pool3) from the DNS request match the 3rd

    topology record therefore, the large-IP system assigns a score of 10 to Pool3. The Large-IP system

    directs the LDNS to transmit the request towards the pool using the greatest score.

12. The LDNS transmits the DNS request to Pool3 within the The United States data center. The way the system

    distributes the DNS demands towards the people of Pool3 isn’t portrayed within this illustration, but

    

    is dependant on the burden balancing mode configured for Pool3.
