SLB (Server Load Balancer) supports several main protocols, including:<\/p>\n

    \n
  1. TCP protocol: Transmission Control Protocol, used to reliably transmit data. SLB can perform load balancing based on the TCP protocol, distributing client TCP connections to backend servers.<\/li>\n
  2. UDP protocol, short for User Datagram Protocol, is designed for connectionless data transmission. SLB also has the capability to balance the load of UDP protocol, distributing client UDP packets to backend servers.<\/li>\n
  3. HTTP protocol: Hypertext Transfer Protocol, used to transfer hypertext between clients and servers. SLB can support load balancing based on the HTTP protocol, distributing and balancing HTTP requests.<\/li>\n
  4. The HTTPS protocol is a secure version of HTTP protocol, which encrypts data being transmitted. SLB also supports HTTPS protocol for load balancing, encrypting and authenticating data through SSL\/TLS protocol.<\/li>\n
  5. WebSocket protocol: A protocol that enables full-duplex communication on a single TCP connection. SLB can support load balancing for WebSocket protocol, distributing and balancing the load of WebSocket connections.<\/li>\n<\/ol>\n

    The above are the protocols primarily supported by load balancing SLB, with different vendors’ products possibly supporting even more protocols.<\/p>\n","protected":false},"excerpt":{"rendered":"
