H3C SecPath vLB virtual load balancer

The H3C vLB product is different from H3C's previous load balancing devices based on customized hardware. It is a software application delivery product that runs on industrial standard server virtual machines.

Leading professional network platform

Based on the industry-leading Comware V7 platform, it supports:

Rich network and security features can meet the application delivery needs in multi tenant environments of data centers.

Separating the control plane from the data plane and optimizing multi-core data forwarding specifically for virtual environments can better utilize computing resources.

The modular architecture and open network platform allow for on-demand operation and control of the network, making it easier to implement NFV/SDN implementation.

Adopting a unified software platform with physical network devices, providing the same functional features and consistent management interface.

Ultra lightweight deployment

Provide an ultra lightweight deployment experience:

Suitable for deployment in data centers, achieving zero transportation, zero cabling, and accelerating business deployment.

Supports mainstream virtualization platforms such as VMware iPadOS, Linux KVM, H3C CAS, etc., fully leveraging the advantages of virtualization to achieve rapid deployment, batch deployment, image backup, fast recovery, and flexible migration.

Provide multiple publishing formats such as ISO, OVA, IPE, etc. to adapt to deployment on different virtualization platforms.

Support flexible deployment of various tools such as virtual machine management platform, network management platform, and local.

Super Business Resilience

Provide strong business flexibility:

Support mainstream virtualization platforms such as VMware iPadOS, Linux KVM, H3C CAS, etc., seamlessly adapting to users' deployment environments.

According to the elastic expansion of user application load, by dynamically adjusting virtual machine resources and licenses, software functions can be smoothly upgraded, device performance can be improved as needed, and business growth needs can be met at any time.

Rich load balancing scheduling algorithms

Support a variety of load balancing scheduling algorithms, and different algorithms can be adopted according to specific application scenarios. The supported algorithms include polling, weighted polling, minimum connection, weighted minimum connection, random, source address HASH, destination address HASH, source address port HASH, and other algorithms. The above load balancing algorithm is applicable to load balancing of servers at layers 4-7. In addition, load balancing for Layer 7 servers also supports distribution based on application features, such as HTTP header fields, content, etc.

Efficient health monitoring algorithm

Support rich health detection algorithms, which can comprehensively detect and check the running status of servers and applications from the network layer and application layer. When conducting health checks, H3C's patented NQA (Network Quality Analyzer) technology is used to ensure that health checks consume minimal system resource overhead, thereby ensuring the performance of application delivery services. The health detection algorithm is suitable for load balancing on servers at levels 4-7.

Load balancing for servers at levels 4-7

Support load balancing for L4 and L7 servers.

4-layer server load balancing: Based on various business applications such as TCP, UDP, and IP, load balancing is performed according to the L4 layer characteristics (IP, port) of packets.

7-layer server load balancing: Based on L7 content, load balancing deeply parses the content carried by messages and processes or distributes them according to the analysis results of the application layer. Support parsing based on HTTP headers, HTTP URLs, HTTP cookies, and HTTP content, and configure the required L7 policies on this basis to distribute HTTP messages and maintain session continuity.

Connection reuse

Support TCP connection multiplexing function, using connection pooling technology, can multiplex a large number of HTTP requests from front-end clients onto a small number of TCP long connections established with back-end servers, greatly reducing the performance load on servers, minimizing the latency caused by new TCP connections between servers, and minimizing the number of concurrent connections on back-end servers, thereby reducing server resource consumption.

Application optimization

VLB 1000 adopts a full proxy mode, fully taking over the application traffic of both the client and server, and supporting any level of protocol field parsing and optimization. VLB 1000 supports multiple parameter template settings such as IP/TCP/HTTP. By setting application parameter templates, the functionality of application delivery can be optimized and the performance of application delivery can be improved.

The IP parameter template provides the Set IP To function. Optimize various types of transmission protocols by setting IP AKS to improve the performance of critical application transmission.

The TCP parameter template provides options for setting the size of the sending and receiving buffers. By adjusting the TCP buffer size to regulate the transmission quality of the link, the goal of optimizing TCP data transmission is achieved.

The HTTP parameter template provides options or parameter settings such as rebalance per request (distribute per request), header modify per transaction (modify per business request), header maxparse length (maximum parsing header length), secondary cookie (secondary cookie setting), content maxparse length (maximum content parsing length), etc., to meet the optimization requirements and performance improvement of HTTP application delivery according to user needs.

Collaborate with SDN controllers to achieve intelligent networks

Cooperating with SDN controllers can achieve:

VLB is based on user cooperation with VNF Manager to achieve one click deployment and deletion.

Support VxLAN three-layer gateway function.

Implement service chain functionality through a controller.

Supports various SDN protocols such as NETCONF and OpenFlow.

Multi tenant load balancing application in data centers

In the data center environment, in order to achieve fast access to tenant application services, it is also necessary to adopt application delivery functions to share and optimize the access traffic of tenant applications. In this case, dedicated vLB products can be deployed for different tenants to provide load balancing functionality, ensuring the response speed and business continuity of tenant services, and improving application reliability;

It can also be used in conjunction with vFW, supporting deployment on the same physical server as vFW;

Typical networking of multi tenant load balancing applications in data centers

Simplify network infrastructure by directly utilizing servers, making it easier for tenants to maintain themselves;

Business elasticity expansion, dynamically adjustable performance, and efficient management

Support load balancing for 4-7 layer servers;

Support a variety of load balancing scheduling algorithms;

Support efficient health check algorithms;

Support multiple attack prevention techniques;
