The SS7 SSU distributes messages among different SS7 network entities that share the same alias using the weighted load strategy. This strategy determines a network entity that receives a message based on the weight that you assign to the entity. The weight determines a relative share of the traffic that the network entity should receive. For example, you defined two entities whose weight is 100 and 200 correspondingly. The network entity with the weight of 100 receives 1/3 of the traffic, while the network entity with the weight of 200 receives the remaining 2/3 of the traffic.
If a network entity fails, the SS7 SSU redistributes the traffic among remaining networking entities according to their weight.
You can define a network entity that receives traffic if other network entities whose weight is greater than zero, fail. This entity is known as secondary network entity, and its weight is always zero. If in the example above, you add one more entity whose weight is set to zero, the SS7 SSU sends messages to this network entity only if the network entities whose weight is set to 100 and 200 correspondingly, fail.
If you define multiple network entities with secondary priority, the SS7 SSU distributes traffic equally among them.
The weighted load strategy enables you to control the traffic distribution depending on capabilities of network entities. For example, if a network entity runs a more powerful server, this entity can serve more traffic, then you would set its load weight relatively higher.
The Remote PC and SSN Addresses subtab contains a table in which each row represents a single SS7 network entity. When configuring a network entity, you need to specify the fields described in Table 3-18.

The Remote Fixed GTs subtab enables you to configure addresses of remote entities in the SS7 network that can be reached using a fixed Global Title.
Figure 3-10 shows an example of a remote fixed GTs configuration.
The SS7 SSU distributes messages among different SS7 network entities that share the same alias using the weighted load strategy. This strategy determines a network entity that receives a message based on the weight that you assign to the entity. The weight determines a relative share of the traffic that the network entity should receive. For example, you defined two entities whose weight is 100 and 200 correspondingly. The network entity with the weight of 100 receives 1/3 of the traffic, while the network entity with the weight of 200 receives the remaining 2/3 of the traffic.

The Remote Dynamic GTs subtab enables you to configure addresses of remote entities in the SS7 network that can be reached using a dynamic Global Title.
The SS7 SSU distributes messages among different SS7 network entities that share the same alias using the weighted load strategy. This strategy determines a network entity that receives a message based on the weight that you assign to the entity. The weight determines a relative share of the traffic that the network entity should receive. For example, you defined two entities whose weight is 100 and 200 correspondingly. The network entity with the weight of 100 receives 1/3 of the traffic, while the network entity with the weight of 200 receives the remaining 2/3 of the traffic.

The Routing tab enables you to define an IM to which SS7 SSU routes an incoming session by specifying a set of parameters known as incoming routing rules. For each incoming routing rule, you need to configure the following parameters:
IM to which SS7 SSU routes an incoming session
Criteria that an incoming session must meet to be routed to this IM
Priority in which SS7 SSU checks incoming routing rules to evaluate whether an incoming session fits the criteria defined in a rule. SS7 SSU applies the first found rule which criteria are met by an incoming session.
For example, if you created multiple rules for the same IM, SS7 SSU begins with the rule that has the highest priority. If an incoming session fits the criteria defined in this rule, SS7 SSU applies the rule and do not check the rest of the rules. Otherwise, SS7 SSU checks whether an incoming session fits the criteria of a rule with a lower priority. SS7 SSU performs this check until SS7 SSU finds a rule whose criteria are met by an incoming session.
You can define incoming routing rules using the Routing tab. The process of defining an incoming routing rule consists of the following steps:
You create a rule and define its name, priority, and the IM for which you are creating the rule. You perform these actions using the Incoming Routing Rules subtab.
You define criteria for each rule that you created in step 1.
The Routing tab enables you to define rules for routing incoming sessions to IMs.
To access the Routing tab:
In the domain navigation pane, expand OCSB.
Expand Signaling Tier.
Select SSU SS7 TDM.
In the configuration pane, click the Routing tab.
The tab contains the following:
List of existing routing rules. This pane is located on the left.
Subtabs with configuration parameters of the routing rule selected in the left pane of existing routing rules. This pane is located on the right.

Name | Type | Description |
---|---|---|
Name |
STRING |
Specifies a unique rule name |
Priority |
INT |
Specifies an order in which SS7 SSU checks routing rules to evaluate if an incoming session fits rule's criteria. SS7 SSU applies the first found rule which criteria are met by an incoming session. The lower the number, the higher the priority. For example, if you created two rules and set Priority of one rule to" 1" and set Priority of another rule to "2", SS7 SSU checks the rule with Priority set to "1" first. You can define an incoming routing rule that SS7 SSU applies if no other rule can be applied, by setting the Priority parameter of this rule to the largest number (that is lowest priority). There is no need to specify incoming routing criteria for such a rule. |
Module Instance |
STRING |
Specifies the URI of an IM to which the SS7 SSU routes an incoming session. The URI has the following format: IM-instance-name.IM-type@domain-id
Example:
