Network Topology and Cluster Interfaces

In addition to the SBC device's existing local IP network connections such as SIP Control and Media interfaces for routing between SIP entities, and the OAMP interface for management, you need to configure additional network interfaces for connectivity with the s. The IP network interfaces used for communication with the Media Components are configured with the special Application Type, "Cluster" (hereafter, referred to as the Cluster interface). The number of ports configured for the Cluster interface depends on the employed network connection type between the SBC device and the Media Components, which can be one of the following:

■

Direct Connection: The SBC device and Media Component are physically cabled port-to-port (i.e., directly, without an intermediary Ethernet switch). The Ethernet port on the SBC device for this connection is associated with a Cluster interface that is dedicated to the Media Component (i.e., no other Media Components can use this port interface).

●

Standalone SBC: The Cluster interface on the SBC device is composed of a single Ethernet port. The Cluster interface on the Media Component is also composed of a single port, which is cabled directly to the corresponding Cluster interface port on the SBC device.

Direct Connection - Standalone SBC

●

SBC in HA: The Cluster interface on the SBC device is composed of a single Ethernet port while the Cluster interface on the Media Component is composed of two Ethernet ports, where one port is cabled directly to the active SBC device and the other to the redundant SBC device:

Direct Connection - HA SBC

The configured operating mode of the Ethernet ports on the Media Component for direct connection depends on the number of ports used for the Cluster interface:

●

1 port: SINGLE port mode

●

2 ports: REDUN_2RX_1TX port mode

■

Indirect Connection (through switch): The Media Component is connected to the SBC device through an Ethernet switch. The Ethernet port on the SBC device for this connection is associated with a Cluster network interface that can be used for multiple Media Components. The Ethernet port can also be associated with OAMP and/or SIP Control network interface application types (not Media).

●

No Switch Redundancy: The Cluster interfaces on the SBC device and Media Component can be composed of a single Ethernet port or two ports (for port redundancy):

Indirect Connection - No Switch Redundancy

The configured operating mode of the Ethernet ports on the Media Component for indirect connection depends on the number of ports used for the Cluster interface:

◆

1 port: SINGLE port mode

◆

2 ports: REDUN_1RX_1TX port mode

The physical Ethernet ports on the Media Component must be allocated as follows:

◆

OAMP interface: Port GE_1, or ports GE_1 and GE_2 for port redundancy (upper ports)

◆

Cluster interface: Ports GE_5, or ports GE_5 and GE_6 for port redundancy (lower ports)

The configured operating mode of the Ethernet ports on the Singling Component for indirect connection depends on the number of ports used for the Cluster interface:

◆

1 port: SINGLE port mode

◆

2 ports: REDUN_2RX_1TX port mode

●

Switch Redundancy: Switch redundancy as well as Ethernet port redundancy can be implemented. The Cluster interfaces on the SBC device and Media Component must be composed of two ports in each Ethernet Group.

Indirect Connection - Switch Redundancy

The configured operating mode of the Ethernet ports for the Cluster interface on the Media Component for switch redundancy must be REDUN_2RX_1TX.

The physical Ethernet ports on the Media Component must be allocated as follows:

◆

OAMP interface: Port GE_1, or ports GE_1 and GE_2 for port redundancy (upper ports)

◆

Cluster interface: Ports GE_5, or ports GE_5 and GE_6 for port redundancy (lower ports)

The configured operating mode of the Ethernet ports for the Cluster interface on the Singling Component for switch redundancy must be REDUN_2RX_2TX.
