The load balancing policy options for balancing traffic among the available uplink ports. Static hash load balancing is the traditional load balancing mechanism used in networks where each flow is allocated to an uplink based on a hash of its 5-tuple. This load balancing gives a distribution of flows across the available links that is roughly even. Usually, with a large number of flows, the even distribution of flows results in an even distribution of bandwidth as well. However, if a few flows are much larger than the rest, static load balancing might give suboptimal results.

Properties Summary
Defined in: lbp:Pol
mo:Annotation
          string:Basic
annotation  (lbp:Pol:annotation)
           NO COMMENTS
topoctrl:DLbMode
          scalar:Enum8
dlbMode  (lbp:Pol:dlbMode)
           The dynamic load balancer (DLB) mode adjusts the traffic allocations according to congestion levels. It measures the congestion across the available paths and places the flows on the least congested paths, which results in an optimal or near optimal placement of the data. DLB can be configured to place traffic on the available uplinks using the granularity of flows or of flowlets. Flowlets are bursts of packets from a flow that are separated by intervals.

scalar:Bool hashGtp  (lbp:Pol:hashGtp)
           GTP Hash for Load Balancing
topoctrl:LbMode
          scalar:Enum8
mode  (lbp:Pol:mode)
           The load balancer administrative state. In all modes of load balancing, static or dynamic, the traffic is sent only on those uplinks or paths that meet the criteria for equal cost multipath (ECMP); these paths are equal and the lowest cost from a routing perspective.
naming:Name

          scalar:Enum8
pri  (lbp:Pol:pri)
           Dynamic Packet Prioritization (DPP) prioritizes short flows higher than long flows; a short flow is less than approximately 15 packets. Short flows are more sensitive to latency than long ones. DPP can improve overall application performance.

Constants
created 2u created In a setter method: specifies that an object should be created. An error is returned if the object already exists.
In the return value of a setter method: indicates that an object has been created.
modified 4u modified In a setter method: specifies that an object should be modified
In the return value of a setter method: indicates that an object has been modified.
deleted 8u deleted In a setter method: specifies that an object should be deleted.
In the return value of a setter method: indicates that an object has been deleted.
DEFAULT 0 --- This type controls the life cycle of objects passed in the XML API.

When used in a setter method (such as configConfMo), the ModificationStatus specifies whether an object should be created, modified, deleted or removed.
In the return value of a setter method, the ModificationStatus indicates the actual operation that was performed. For example, the ModificationStatus is set to "created" if the object was created. The ModificationStatus is not set if the object was neither created, modified, deleted or removed.

When invoking a setter method, the ModificationStatus is optional:
If a setter method such as configConfMo is invoked and the ModificationStatus is not set, the system automatically determines if the object should be created or modified.
