Load Balancing & Fail Over
• Load Balancing is a technique to distribute the workload across two or more network links in order to maximize throughput, minimize response time, and avoid overload. • Fail Over protection system is to maintain if the primary link is interrupted, it will automatically enable the backup path (link the second, third, etc.) Type Load Balancing.
• Per Packet Load Balancing
- In MikroTik using a feature called Interface Bonding - The division of the load based on packet-packet (packet 1 via a gateway, packet 2 through gateway b)
• Per Connection Load Balancing
- Using features in IP Mikrotik Bernama NTH mangle - The division of the load based on connections (1 connection through a gateway, via the gateway connection to 2 b)
• Per address-pair connection Load Balancing
- Features ECMP and PCC (Peer Connection Classified) - Pebagian traffic based on the IP address of the connection and the origin and destination of the connection
• Custom Load Balancing (Policy Routing -> route mark)
Equal Cost Multi Path (ECMP)
• ECMP allows the router has more than one gateway to one destination network. • Each gateway will be selected based on ECMP algorithm Round Roubin of combination SRC / DST address
• The same gateway can be written repeatedly.
