Design architecture and method for secure load balancing by utilizing SSL communication protocol

Abstract

The invention discloses design architecture and a method for secure load balancing by utilizing SSL communication protocol, in particular to provide secure and reliable data communication for client and load balancing equipment by introducing SSL (Security Socket Layer) communication protocol. The invention mainly designs a processor SSL-PU based on SSL encryption, wherein, the processor SSL-PU is loaded in a load balancer and comprises a processing unit (PU), a memory cell (Flash, SRAM, DDR SDRAM, etc.), an Ethernet network controller (PCI, PCI-X, PCI-E) and GbE PHY (RJ45 interface). SSL-PU well solves the security problem caused by traditional load-balancing equipment and client clear text and the problem that traditional SSL encryption technology based on software excessively occupies system CPU and memory resources, thereby saving server bandwidth, increasing throughput and improving flexibility and availability of network; the processor well realizes the security data interaction with the client, and delivers data in the form of clear text to a load-balancing module; the load balancing module locates a request to a corresponding server according to load balancing algorithm; the server transmits data to the load balancing equipment; and the load balancer with an SSL-PU module transmits encrypted security data to the client, thereby completing secure data interactive access. The invention is particularly suitable for secure load-balancing scheduling of load balancing equipment of which the back end is a cluster system.
