About This Chapter
eSpace IVS provides medium, large, and extra large network schemes to apply to surveillance
scenarios of different scales.
4.1 Network Overview
eSpace IVS networks can be classified into the following types by the number of connected
cameras: medium, large, and extra-large.
4.2 Medium Network Scheme
In a medium network scheme where 128 to 1024 cameras are installed, eSpace IVS is
deployed in either single-level single-domain mode or multi-level single-domain mode.
4.3 Large Network Scheme
In a large network scheme where 1024 to 5000 cameras are installed, eSpace IVS is deployed
in multi-level single-domain mode.
4.4 Extra Large Network Scheme
In an extra large networking scheme where more than 5000 cameras are installed, eSpace IVS
is deployed in multi-level multi-domain mode.
4.1 Network Overview
eSpace IVS networks can be classified into the following types by the number of connected
cameras: medium, large, and extra-large.
Background
The eSpace IVS system can be deployed in distributed mode, which can be subdivided into
three submodes: single-level single-domain, multi-level single-domain, and multi-level
multi-domain. The two concepts level and domain are described as follows:

Level
Indicates a service node. For example, a public security bureau has installed an eSpace
IVS system, and police stations under this bureau have deployed cameras in important
surveillance areas. Each police station is a service node. Only one set of management

units is required for the public security bureau, and one or more media units are required
for each site according to the number of access cameras. After these units are deployed,
the public security bureau can monitor and manage all police stations, and the police
stations can monitor and manage their own areas.

Domain
Indicates a group of interconnected surveillance systems. Domains can be classified into
local and external domains. An external domain can be an eSpace IVS system or a
third-party surveillance system. For example, an eSpace IVS system is installed in the
public security departments of city A and city B. With multi-domain management, users
in the public security departments of city A and city B can view each other's surveillance
videos.

Figure 4-1 Medium network scheme (single-level single-domain)
A media unit represents a service node. As shown in Figure 4-1, in single-level single-domain
mode, only one management unit and one media unit are deployed, and there is only one
service node. In multi-level single-domain mode, however, multiple media units are deployed
and there are multiple service nodes. Users can choose to deploy eSpace IVS in single-level
or multi-level mode in terms of the number of service nodes.
For example, if eSpace IVS is deployed in a supermarket chain in single-level single-domain
mode, one management unit, one intelligent analysis unit, and one media unit are installed in
its headquarters, and cameras are installed in individual branches of the chain.

About This Chapter
The eSpace IVS platform features high reliability and security.
6.1 Reliability
The eSpace IVS platform uses various technologies to ensure network, host, application, and
service reliability.
6.2 Security
To ensure the system security, the security maintenance on the eSpace IVS system is
conducted at different layers, and each layer has a security solution.
6.1 Reliability
The eSpace IVS platform uses various technologies to ensure network, host, application, and
service reliability.
6.1.1 Network Reliability
The eSpace IVS system uses various redundancy approaches to ensure comprehensive system
reliability.
Customer Benefits
The eSpace IVS system provides a highly reliable network for users. Upon detecting a
component failure, the system automatically switches services to the available component.
Scenario
An eSpace IVS system has been installed in a traffic surveillance center, and the management
unit of the eSpace IVS system is deployed in two-node cluster mode. One day, the active host
housing the management unit became faulty. Thirty seconds later, the standby host detected

Description
Networking
redundancy
Involves network redundancy and host redundancy:

Network redundancy
All network devices (such as routers and firewalls) have a backup. A
heartbeat mechanism is used between routers. When the active router
fails, all hosts automatically switch to the standby router.

Host redundancy
All hosts are deployed in two-node cluster mode. A heartbeat
mechanism is used between two hosts. When the active host fails, the
standby host takes over services automatically.
Data
synchronizat
ion
In two-node cluster mode, files and databases on an active host need to be
synchronized to the standby host. The eSpace IVS system supports two data
synchronization schemes:

High reliability scheme with a mounted disk array
When a disk array is mounted, the eSpace IVS system stores the data in
the disk array, and such data does not need to be synchronized to the
standby host. When the standby host takes over services of the active
host, the disk array is automatically mounted to the standby host (that is,
the new active host).

Less high reliability scheme without a mounted disk array
When no disk array is mounted, the active and standby hosts of the
eSpace IVS system synchronize data in milliseconds.
6.1.2 Host Reliability
A single host uses redundancy design for its components, such as the network adapter and
hard disk, to ensure its reliability.
Customer Benefits
The reliability of a single host is improved. The failure of a single component does not affect
the system operation.
Scenario
An eSpace IVS system has been installed in a traffic surveillance center. One day, the host
that houses the management unit encountered a hard disk failure, but the system continued to
run properly because the hard disk had a backup.

Component
redundancy
Component redundancy is deployed as follows:
Host
monitoring

Two network adapters are configured. When the active network adapter
fails, the standby network adapter automatically takes over the services.

Two hard disks are configured, and they are mirrored in Redundant
Array of Independent Disks 1 (RAID 1) mode. The failure of one hard
disk does not affect data reading or writing.
The host operating system is monitored, and thresholds for monitored items
are set. The monitored items include disk usage, CPU usage, memory
usage, and I/O status. When a monitored item exceeds the preset threshold
(for example, the disk usage reaches 95%), an alarm is generated,
prompting users to handle the alarm in time. If an alarm for disk usage is
generated, users can delete unnecessary files or add a hard disk.
6.1.3 Application Software Reliability
The eSpace IVS system ensures the reliability of application software by software
programming.
Customer Benefits
Application software reliability has the following benefits:

The application software can automatically recover from a fault (for example, massive
access, memory access violation, or other exceptions), improving the running reliability
of a single host.

A notification is sent to users when an application software fault needs manual
processing.
Scenario
An eSpace IVS system has been installed in a traffic surveillance center. One day, the eSpace
IVS system was attacked by massive malicious access. When detecting this attack, the eSpace
IVS software automatically denied the excess access traffic, ensuring the proper running of
the eSpace IVS system.


The maximum number of live videos and the maximum number of
video recordings are preset on the media server according to the server's
performance. When the number of video requests exceeds the preset
maximum, the media server rejects additional requests, ensuring its
stable running.

The maximum number of concurrent requests is preset on the
management server according to the server's performance. When the
number of concurrent requests exceeds the preset maximum, the
management server rejects additional requests, ensuring its stable
running.

The application software automatically starts upon system startup.

The monitoring program monitors the application software status. Upon
detecting that the software is not found or does not respond, the
monitoring program automatically restarts the software.

An alarm is generated and sent to the eSpace IVS client when the
application software encounters any exception. Users then can handle
the fault in time.

Some application software alarms can be automatically cleared. The
application software periodically detects whether an alarm is cleared.
Upon detecting that an alarm has cleared, the application software
generates a clear alarm, with no need for manual confirmation.


When the database encounters an exception (for example, file damage),
users can restore the latest backup data, mitigating data loss.

Log compression and backup
When disk space occupied by log files reaches the preset maximum, the
system automatically compresses and saves the earliest logs. When the
size of the saved log files exceeds the preset threshold, the system
automatically deletes the earliest files.
6.1.4 Service Reliability
After the eSpace IVS system recovers from a fault, its services automatically restore.
Customer Benefits
Service reliability has the following benefits:

Ensures that services are stable.

Complies with the operation habits of users.
