On the left is a view of the network utilizing stand-alone appliances while on the right is a view of the network achieving the same aim with an integrated services module approach . After achieving generally qualified status , the minor release transitions into the restricted maintenance phase . After the general deployment phase , the major release transitions into the mature maintenance phase . The view of a server tier is depicted in the diagram below with the physical view on the left and the logical segmented view on the right . The next phase of the attack consists in identifying the vulnerabilities of the remote system . Baseline thresholds create a threshold that adapts to the typical traffic pattern for each link for the same time window each day , week , or every two weeks . Threshold values may be set with user-specified levels or with baseline values automatically calculated from performance history . In this phase , the release receives defect repairs only for severity 1 and severity 2 defects that the customer finds . A customer who " just ai n't gonna get it " deserves a special warning sign . Baseline thresholds are set as a percent of the average ( 110 % to 500 % ) , where 100 % equals the calculated weighted average . The general deployment phase lasts for 18 to 24 months , and product defects in this phase are addressed in maintenance releases . With the DC Core , DC Aggregation and possibly the DC Access Layers using Layer 3 protocols to maintain forwarding tables , so too the need to ensure that flapping routes do not impact network stability .
