Did you know that ZEVENET implements different techniques to provide higher performance and high scale for non-connection oriented and real-time services like UDP (User Datagram Protocol), SIP (Session Initiation Protocol), VoIP (Voice over IP), VPN (Virtual Private Network), SYSLOG (System Logging Protocol), DNS (Domain Name System), DHCP (Dynamic Host Configuration Protocol) among others?
Due to the nature and requirements of all those protocols the different techniques that the ZEVENET technology uses are the following:
1. sNAT/dNAT: For application layer protocols that require some negotiation between clients and backends, it supports address translation according to application layer information (like SIP) that requires connection tracking systems. The connection can be transparent (the real server knows the client IP address) or not. This load balancing could achieve several hundred thousand packets per second.
2. Stateless dNAT: Address translation with transparency using fast path and without connection tracking which provides very high performance for real-time services hiding the local infrastructure. This method is able to move a few million packets per second without concern. This new load balancing technique has been designed by the ZEVENET Team especially for real-time UDP protocols although TCP is also possible to be used.
3. DSR: High performance load balancing at layer 2 using a fast path in order to provide the best performance. Some backends configurations are required before using this technique. Several million packets are able to handled by ZEVENET using this load balancing method.
With all these methods designed and implemented by ZEVENET Team to scale non-connection oriented services with the best performance. Let’s try ZEVENET.
