It is Layer 7-protocol aware and can enforce network policies on Layer 3 to Layer 7 and with FQDN using an identity-based security model that is decoupled from network addressing. Cilium implements distributed load balancing for traffic between Pods and to external services, and is able to fully replace kube-proxy, [ 53 ] using XDP , socket ...
Load balancing can optimize response time and avoid unevenly overloading some compute nodes while other compute nodes are left idle. Load balancing is the subject of research in the field of parallel computers. Two main approaches exist: static algorithms, which do not take into account the state of the different machines, and dynamic ...
Application Request Routing (ARR) is an extension to Internet Information Server (IIS), which enables an IIS server to function as a load balancer. With ARR, an IIS server can be configured to route incoming requests to one of multiple web servers using one of several routing algorithms.
Server-load balancing uses one or more techniques including service-based (global load balancing) or hardware-based (i.e. layer 4–7 switches, also known as a web switch, content switch, or multilayer switch) to share traffic among a number of servers or web caches.
The protocols in use today in this layer for the Internet all originated in the development of TCP/IP. In the OSI model the transport layer is often referred to as Layer 4, or L4, [2] while numbered layers are not used in TCP/IP. The best-known transport protocol of the Internet protocol suite is the Transmission Control Protocol (TCP).
Network load balancing is the ability to balance traffic across two or more WAN links without using complex routing protocols like BGP.. This capability balances network sessions like Web, email, etc. over multiple connections in order to spread out the amount of bandwidth used by each LAN user, thus increasing the total amount of bandwidth available.
Application Layer Gateway (ALG) software or hardware may correct these problems. An ALG software module running on a NAT firewall device updates any payload data made invalid by address translation. ALGs need to understand the higher-layer protocol that they need to fix, and so each protocol with this problem requires a separate ALG.
Load balancing can be performed on HTTP, HTTPS, VPN, or any TCP/IP traffic using a specific port. Load balancing often involves destination network address translation so that the client of the load-balanced service is not fully aware of which server is handling its requests. Some layer 4–7 switches can perform Network address translation ...
