Understanding Sessions
The session manager organizes individual sessions into groups and sets (see Figure 5-3).
Figure 5-3 Organization of Sessions
The backhaul sessions and groups include the following components:
• Session—a connection between two points, defined by a local IP address and port and a remote IP
address and port. The MGX 8260 Media Gateway supports four sessions per set, two for each
session group.
• Session Group—a collection of one or more sessions for a single MGC. Typically, the individual
sessions implement network redundancy. The MGX 8260 Media Gateway supports two session
groups per set.
• Session Set—a collection of session groups, typically used to group session groups for redundant
MGCs. The MGX 8260 Media Gateway supports up to six session sets for a total of up to 24
sessions.
When adding sessions, you create a structure that supports reliable operation. The goal for a
fully-redundant system is to provide multiple management sessions to multiple MGCs via multiple
physical networks (see Figure 5-4).
Figure 5-4 Logical Session Model
With full redundancy, you configure the following:
• Four sessions:
– Session 1 (MGX 8260 Net 1 to Active MGC Net 1)
– Session 2 (MGX 8260 Net 1 to Standby MGC Net 1)
