Load Balancing Solution for New Business System

Requirement analysis

With the popularity of computers and the rapid development of the Internet, enterprise business systems have become one of the factors that affect the efficient operation of enterprises. Stable and efficient business system is the key to guarantee the enterprise business and user access. Therefore, when new business systems are constructed, the overall structure of business systems shall be considered to guarantee the comprehensive performance of business systems, to meet the needs of future high-speed business development.

Issues of traditional business system construction

Business systems support the entire process of user access, from the server, Web portal, ISP to the client, and bottlenecks in each link affect users' access experience. As the business grows and the number of visiting users increases, device performance begins to decline, and the intuitive feeling to users is slow response, no answer for a long time, and eventually no response at all, which greatly affects their experience.

Traditional solutions, such as purchasing high-performance servers to replace existing ones and leasing links with higher bandwidth, are costly and only address current needs. The same problems will persist as business grows.

H3C load balancing solution for new business systems

A flexible and efficient business system is built based on H3C load balancing products. From links to servers, it guarantees the flexibility and stability of business systems and the expansion needs for future growth.

Loads at the link side:

They can work with NAT application gateways for networking; different source addresses are used for different links, thus ensuring that round-trip messages pass the same link.

Health detection checks the connectivity of any node within the link, thus effectively ensuring the accessibility of the entire path.

Scheduling algorithms balances traffic across multiple links and supports load balancing by bandwidth.

The quality of the link is dynamically calculated using proximity algorithms to distribute traffic to a currently better link.

When traffic exceeds the bandwidth ratio of a link, new traffic (non-matching persistent traffic) will no longer be distributed to that link with the bandwidth busy protection, while existing traffic will continue to be distributed by that link.

They can be applied in conjunction with server load balancing to achieve balanced traffic between multiple links for external users to access internal servers, while also achieving balanced traffic among multiple servers.

Loads at the server side:

Based on packet-by-stream distribution, packets from the same stream are distributed to the same server.

Load balancing based on application layer messages allows deep rewriting of messages for message tracking, content filtering, targeted surrogate answering, etc.

Web caching, SSL decryption and other functions are provided to optimize users' Web service access experience.

The integrity and continuity of server access is ensured by high reliability.

They have full range of IPS, AV, and Web protection to provide reliable network security protection.

Benefits

They have link loads and server loads to improve access efficiency and stability.

Message rewriting can shield untrusted information on the clients, as well as sensitive information on the intranet server, to improve business system security.

The full range of security protection leads to "secure" load balancing devices.
