Load balancing with traffic flow

  1. Direct Analysis & Distribution within One Network:
    • This method involves load balancing within a single network using a load balancing switch. The user requests a service via a URL (step 1). The load balancing is handled internally by the switch, which directly analyzes traffic and distributes the load to various servers within the network.
  2. URL Redirection:
    • Here, a user requests a service using a URL (step 1). The network then uses URL redirection to guide the user to the best service URL (step 2), which may involve multiple redirections within one network until the most optimal service endpoint is selected for the user (step 3).
  3. GSLB (Global Server Load Balancing) Control:
    • In this approach, the user starts with a DNS lookup when requesting a service (step 1). The DNS uses the geographic information from the client’s IP to return the best service IP (step 2). The user then requests the service at the given IP address (step 3). This method uses global considerations such as network and service load to balance traffic across multiple networks.
  4. IP Anycast with BGP (Border Gateway Protocol):
    • Users request a service directly using an IP address (step 1). The best service IP is determined via the BGP, which routes traffic based on the shortest available path (step 2). With IP anycast, the user is automatically directed to the nearest or most appropriate service location based on network routing protocols.

Each of these methods is designed to distribute network traffic efficiently. The goal is to ensure service reliability and performance, optimize server use, and improve the overall user experience by reducing latency.

Direct Analysis and Distribution:

Traffic flows directly from a group of users to a group of servers.
This traffic can be distributed based on static information such as TCP/IP headers, user IP/Port, etc., through a “Static hash map.”
Alternatively, “Dynamic Analysis Traffic” can be used to distribute the load based on throughput or service load.
These processes require guidelines on “How to Control” and “How to Analysis.”
Pre-connection Routing Change:

The CDN Load Balance (GLBS) operates differently based on User IP and Request URL.
It controls responses through “nice destination IP return” or “BGP advertisement Routing Control,”
Or distributes traffic through “Response redirect URL.”
All these processes are executed through a Control phase.
