■
Interface profiles—Specify a set of characteristics that can be dynamically
assigned to IP interfaces. A service definition must use at least one interface
profile.
■
Policy lists—Specify policy actions for traffic traversing an interface.
■
Classifier lists—Specify the criteria by which the router defines a packet flow.
■
Rate-limit profiles—Specify a set of bandwidth attributes and associated actions
that limit a classified packet flow or a source interface to a rate that is less than
the physical rate of the port.
■
QoS parameters—Specify attributes such as shaping rate, shared-shaping rate,
assured rate, and scheduler weight for scheduler nodes and queues.
■
QoS profiles—Specify queue, drop statistics gathering, and scheduler configuration
for an interface hierarchy.
Creating Service Definitions
To create a service definition, you use the JUNOSe software’s macro language to
specify the parameters that define the desired service. A macro file can define only
one service—however, the file can have multiple templates to define characteristics
of the desired service. You create service definitions independent of the Service
Manager commands and operations, which are performed on the E Series router.
For detailed information about the JUNOSe software’s macro language, see the
Command Line Interface chapter in JUNOSe System Basics Configuration Guide .
Figure 29 on page 642 is an example of a service definition macro file that creates a
tiered service. A tiered service typically provides set bandwidths for both inbound
and outbound traffic for a subscriber. In this example, the input (inputBW) and output
(outputBW) bandwidth values are parameterized. This example assumes that QoS
profile triplePlayIP and QoS parameter maxSubscBW are configured. See “Service
Definition Examples” on page 684 for additional service definition examples.
Service Manager only tracks JUNOSe objects that are passed back in the env.setResult
method when a service definition is executed. Table 139 on page 640 describes the
supported objects:
