Bam Networking - Huawei U-SYS MRS6100 Technical Manual

Technical Manual
U-SYS MRS6100 Media Resource Server
provides a complete set of practical operation and maintenance methods and tools, to
guarantee the normal running of the system, minimize the business cost, and improve
the quality of communication service.

6.2.1 BAM Networking

The BAM is the core of the local operation and maintenance system. Being the
TCP/IP server, the BAM responds to connection requests from clients (or
workstations), creates connections, analyzes commands from clients, and carries out
appropriate processing. Meanwhile, the BAM responds to connection requests from
the equipment, creates connections, achieves the communication between the BAM
and the equipment, and receives and processes data loading requests and alarms
from the equipment.
The BAM provides two network interfaces to core LAN Switches, thereby being
connected to the HSCIs in the basic frames. The two network interfaces provided by
the BAM are respectively in the same network segment with the active/standby
SMUIs (two closed LANs connected to the equipment). The connection to a client
belongs to a different network segment (an open operation and maintenance LAN).
The three network segments are not seeable with each other. In this way, the network
security is ensured to a certain extent and the dependence on the system security is
reduced. The network configuration of the BAM is shown in Figure 6-3.
