    In this session, we will discuss how these choices will affect cluster routing and load balancing, focusing on KubeProxy modes iptables vs IPVS and network solutions. More From Medium. If you are using IPVS proxier with your own IPVS rules in the environment, this parameter should be specified, otherwise your original rule will be cleaned. Kubernetes networking deep dive: Did you make the right choice? For all the 3 interface types in Routing table, we can also find the corresponding matches in the ip addr result below. But if the first pod where a packet was sent did not respond — then a connection fails, while in the user space proxy mode kube-proxy will try to send it to another pod.

    The main difference between iptables and IPVS, is.IPVS supports a lot more load balancing algorithms than iptables mode round-robin onlythese scheduling algorithms are implemented as kernel modules.

    The difference in CPU usage between iptables and IPVS is relatively insignificant until you get beyond 1, services (with 10, backend pods).The main purpose of this blog is to help Kubernetes users to get comfortable with K8S major network components, common usage patterns, and corresponding troubleshooting tools.

    Kube-proxy in IPVS mode: The IPVS implementation uses a hash table managed by the kernel to establish the destination of a packet. kube-proxy's.IPVS supports 8 load balancing algorithms round robin, weighted round robin, least-connection, weighted least connection, locality-based least-connection, locality-based least-connection with replication, destination-hashing, and source-hashing and 3 packet-forwarding methods NAT, tunneling and direct routing.

    IPVS is a very specialized technology whereas iptables/nftables is a generic and flexible firewall (which is in most cases anyway needed somehow).The userspace mode is old and inefficient.

    IPVS-Based In-Cluster Load Balancing Deep Dive. And the most recent mode. It uses the netlink kernel module and creates new IPVS rules for.To illustrate these differences we tested with and without keepalive connections.

    IPVS supports more sophisticated load balancing algorithms than IPTABLES (least load, least connections, locality, weighted, etc.). IPVS.The iptables mode is better since it uses the kernel feature of iptables, which is fairly mature.

    nodes in the cluster - We then measured performance on the client node in both iptables and IPVS mode - With various numbers of Kubernetes services with.Notice service IPs under kube-ipvs0 interface will have a corresponding matching record in the ipvs load balancing results, as shown in the ipvsadm output below.

    On this node the kube-proxy service is binding on the port allocated so no one another service will use it, and also it creates a set of iptables rules:.

    For both iptables and IPVS mode, the response time overhead for kube-proxy is associated with establishing connections, not the number of packets or requests you send on those connections.

    IPVS aka layer-4 switching runs on a host at the front of a cluster of real servers.

    The packet is compared against iptables rule and then forwarded to a pod named kube-Proxy, which operates as an application to forward packet to backend pods.

    Remember though that in this chart we are showing the worst case scenario of microservices that use a new connection for every request.

    If you plan to use IPVS with other programs that use iptables then you will need to research whether they will behave as expected together.Forum Ipvs vs iptables
