AES
See Advanced Encryption Standard.
API
See application programming interface.
Advanced Encryption Standard (AES)
The AES algorithm is a symmetric grouped password algorithm and one of the most popular symmetric key encryption algorithms released by the U.S. National Institute of Standards and Technology (NIST) on November 26, 2001. It is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST). It supersedes the Data Encryption Standard (DES). AES adopts a symmetric-key algorithm for both encrypting and decrypting the data, where the block size is 128 bits and the key size is 128 bits, 192 bits, or 256 bits.
activation
An operation that enables a registered subscriber to enter the active state and use services provided by a carrier.
active period
A specific period in the life cycle of a subscriber account. The subscriber account is in Active state within the active period. A subscriber account enters the Active state after being activated. Subscribers whose accounts are in Active state can use the telecommunications services provided by carriers.
alarm dump

The BCM supports centralized and unified network management, such as fast network fault locating, efficient network performance analysis, and quick response to service requirements, to provide good user experience.
background job
A job that operates without interaction with the user. Usually, its operation will not affect other jobs. In a distributed system, one background job is assigned to as many nodes as possible for concurrent processing to improve the processing efficiency. Generally, background jobs are asynchronous jobs that do not have a demanding requirement on real-time capability, for example, data consistency verification.
backup server
A server that runs the backup software, schedules and monitors backup and recovery jobs, manages backup storage and production system, and receives and responds to user requests. A backup server also provides the functions of a backup proxy.
baud rate
The maximum rate of signal state changes per second on a communications circuit. If each signal state change corresponds to a code bit, then the baud rate and the bit rate are the same. It is also possible for signal state changes to correspond to more than one code bit, so the baud rate may be lower than the code bit rate.
C
CSV
See comma separated values.
Cluster
A computer technology that integrates a set of loosely connected servers to work together so that in many respects they can be viewed as a single system. A cluster is used to improve system stability, reliability, data processing capability, and service capability. For example, a cluster is used to reduce single-point failures, share storage resources, load balances, and improve system performance.
clock source
A device that provides standard time for the NTP configuration.
comma separated values (CSV)
A CSV file is a text file that stores data, generally used as an electronic table or by the database software.
D

DNS
See domain name service.
DR site
See disaster recovery site.
Data Encryption Standard (DES)
A specification for encryption of computer data developed by IBM and adopted by the U.S. government as a standard in 1976. DES uses a 56-bit key.
data backup
A method of copying key data to the backup storage area to prevent data loss in case the original storage area is damaged or a failure occurs.
data restoration
A method for retrieving data that is lost due to damage or misoperations.
digital signature
A message signed with a sender's private key that can be verified by anyone who has access to the sender's public key. Digital signature gives the receiver the reason to believe the message was sent by the claimed sender. A proper implementation of digital signature is computing a message digest for the message sent from the sender to the receiver, and then signing the message digest. The result is called digital signature and is sent to the receiver together with the original message.
disaster recovery site (DR site)

domain name service (DNS)
A hierarchical naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participants. The DNS distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain.

FusionStorage provides standard Small Computer System Interfaces (SCSIs) and Internet Small Computer Systems Interfaces (iSCSIs) for upper-layer applications and VMs.
firewall
A security system consisting of a combination of hardware and software that limits the exposure of a computer or computer network to attack from crackers; commonly used on local area networks that are connected to the internet. Firewalls can be implemented in either hardware or software, or a combination of both.
floating IP address (FIP)
An IP address that a high availability (HA) system uses to communicate with the external system. The active server and standby server have separate IP addresses. For example, the IP address of the active server is IP1 and the IP address of the standby server is IP2. When communicating with the external client, the active or standby server uses IP3, and IP3 is bound to the network adapter of the active server. At this time, the active server has two IP addresses, namely IP1 and IP3. The standby server has only IP2, therefore, it does not provide services to the external client. When an active/standby switchover occurs, the active server releases IP3, and IP3 is bound to the network adapter of the standby server. This is called floating.

Internet Protocol version 4 (IPv4)
The current version of the Internet Protocol (IP). IPv4 utilizes a 32bit address which is assigned to hosts. An address belongs to one of five classes (A, B, C, D, or E) and is written as 4 octets separated by periods and may range from 0.0.0.0 through to 255.255.255.255. Each IPv4 address consists of a network number, an optional subnetwork number, and a host number. The network and subnetwork numbers together are used for routing, and the host number is used to address an individual host within the network or subnetwork.
Internet Protocol version 6 (IPv6)
An update version of IPv4, which is designed by the Internet Engineering Task Force (IETF) and is also called IP Next Generation (IPng). It is a new version of the Internet Protocol. The difference between IPv6 and IPv4 is that an IPv4 address has 32 bits while an IPv6 address has 128 bits.
