PRODUCT FEATURES
PRODUCT SPECIFICATION
Product Functions Function Descriptions
Comprehensive Functions A fusion of link load balancing, server load balancing, global load balancing, SSL offload&acceleration, HTTP compression, Cache and other application delivery technologies.
Application Virtualization The N:M virtualization technology can realize virtualization by integrating multiple devices into a resource pool, which is then divided into M logical devices as needed to achieve dynamic scheduling of resource pools in a cloud computing environment.
Outstanding Performance Maximum performance of a single device can reach 400 G*, and performance aggregation and multiplication is available through N:M virtualization
Excellent Reliability N:M virtualization, silent dual system, dual-system hot standby, VRRP multi-master and other modes are supported to meet reliability needs of various levels.
Personalized programming AD-Rules is apt at meeting personalized needs of users.
Rich Network Features It supports routing protocols such as IPv4/v6, NAT, MPLS, OSPF, RIP, and dynamic/static routing.
Considerate Design Login and logout of the dynamically expandable server will have no impact on the existing network.
Floating Long Connection Application services with a long connection time can be disconnected actively and reload a new connection according to the predetermined polices.

Server Load Balancing and Optimization

Product Functions Feature Description
Four Layers of Load Balancing Rich 4-layer load balancing algorithms are provided, including polling, weighted polling, minimum connection, weighted minimum connection, source address hash, Source address  hash, destination address hash, minimum expected delay, minimum queue, random, weighted random, and minimum server load.
Seven Layers of Load Balancing Rich 7-layer load balancing algorithms are provided, including minimum server load, http header, http content, polling, weighted polling, minimum connection, weighted minimum connection, source address hash, Source address  hash, destination address hash, minimum expected delay, minimum queue, random, and weighted random.
SSL offload&acceleration Featuring SSL proxy, termination, and unload technologies, and supporting SSL hardware acceleration and session persistence, it greatly reduces pressure on servers and shortens user’s access time to resources.
Source Address Traceability With x-fordward-for, it can identify the HTTP request header field of the original IP address of the client connected to the Web server through HTTP proxy or load balancing, making access source traceable.
Connection Multiplexing Multiple connections can be multiplexed into a single connection, and a connection can also be split into multiple connections.
HTTP Compression HTTP cache and compression help significantly reduce server pressure, shorten time spent in downloading resources and improve efficiency.
session persistence Provide a variety of session persistence policies, including source IP, http cookie (multiple cookie modes), http header, http content, SIP, SSL id, RTP/RTCP/RTSP, etc.
Health Detection Algorithm ARP, ICMP, TCP, HTTP, DNS, service-based and content-based algorithms, as well as custom four-layer and seven-layer algorithms are supported.
Integration with Cloud Management Platform Interface with mainstream cloud management platforms such as OpenStack to enable automatic translation and distribution of configurations.

Server Load Balancing and Optimization

Product Functions Feature Description
Two-way Load Balancing Inbound and outbound link load balancing helps improve bandwidth utilization of multi-link resources.
DNS Transparent Proxy Based on load balancing algorithm, it forwards DNS request on behalf of users to avoid DNS overload of a single operator and maintain a balance of bandwidth utilization among multiple operator lines.
Intelligent DNS Intelligent selection of operator link egress based on traffic
Dynamic and Intelligent Adjustment Dynamic and intelligent adjustment of link exits are allowed based on load, packet loss rate, delay, etc.
Link Health Check Provide multiple health check algorithms, including ARP, ICMP, TCP, HTTP, DNS, service-based, content-based, custom four-layer to seven-layer, etc.
Link Scheduling Algorithms Rich scheduling algorithms are provided, including polling, weighted polling, minimum connection, weighted minimum connection, source address hash, Source address  hash, destination address hash, minimum expected delay, minimum queue, random, weighted random, type of data application, proximity, and bandwidth algorithm.
Link Backup Several links can serve as backups for each other, enabling link backup.

Server Load Balancing and Optimization

Product Functions Feature Description
DNS-based Global Global DNS-based resolution and data synchronization between devices are enabled, thus switching user traffic to the best data center.
IPanycast-based Global Compatible with RIP, OSPF and other routing protocols, it can publish IP address of virtual services through multiple dynamic routing protocols, make a difference in routing through changing the value of cost, and switch user traffic to the best data center.
Global Health Check RTT dynamic monitoring, dynamic publishing of healthy routing, and detection of data center availability and accessibility are allowed.
Global Fault Alarm By using email, SMS and SNMP Trap, administrators can select alarm trigger events and alarm methods based on the concerns of business security in the domain, such as server downtime, network attacks, link interruption, and other failures.

Server Load Balancing and Optimization

Product Functions Feature Description
DDoS DoS and DDoS protections are provided to ensure normal operation of daily business.
Firewall Support stateful firewall, packet filtering, etc.
NAT Support source NAT, destination NAT, one-to-one NAT, NAT address pool and other NAT functions.
Basic Attack Protection Support basic attack protection such as DoS/DDoS and SYN Flood attacks, HTTP Flood and intrusion prevention of large traffic

These specifications apply only to DPtech products available on the international market.
