Abstract: Embodiments are directed to routing requests with different protocols to the same destination. In one scenario, a computer system receives a request that uses a specified protocol. The request includes a request source identifier and a request destination identifier. The computer system identifies, based on both the request source identifier and the request destination identifier, a destination to send the request to and generates a routing entry for the request that indicates which destination the first request was sent to. The computer system receives another request that uses a different protocol. This request includes a request source identifier and a request destination identifier of its own. The computer system determines that the request source identifier and request destination identifier of the subsequent request match those of the generated routing entry, and routes the subsequent request to the destination indicated in the routing entry.

Abstract: The present invention extends to methods, systems, and computer program products for synchronizing state among load balancer components. Embodiments of the invention include load balancers using a consistent hashing algorithm to decide how new connections should be load balanced. Use of consistent hashing algorithm permits load balancers to work in a stateless manner in steady state. Load balancers start keeping flow state information (destination address for a given flow) about incoming packets when it is needed, i.e. such as, for example, when a change in destination host configuration is detected. State information is shared across load balancers in a deterministic way, which allows knowing which load balancer is authoritative (e.g., is the owner) for a given flow. Each load balancer can reach the authoritative load balancer to learn about a flow that cannot be determined locally.

Abstract: When a load balancer detects that a virtual address is associated with a single destination address, the load balancer sets a flag to distinguish the virtual address from virtual addresses that are associated with a plurality of destination addresses. The load balancer instructs the router to bypass the load balancer for network packets that are addressed to the virtual address, and refrains from storing subsequent flow state for the virtual address. When the virtual address is to be scaled up with an additional destination address, the load balancer sets a flag to distinguish the virtual address from virtual addresses that are associated with a single destination addresses. The load balancer instructs the router to route network packets that are addressed to the virtual address through the load balancer, instead of bypassing the load balancer, and starts storing flow state for the virtual address.

Abstract: A load balancer that is able to detect and mitigate a Denial of Service (DOS) attack. The load balancer is placed in the flow path of network data packets that are destined for one or more tenant addresses. The load balancer analyzes performance parameters regarding the network data packets that are destined for the one or more tenant addresses and are received at the load balancer. The performance parameters describe network data packet flow to the tenant addresses. The load balancer detects, based on the analysis of the performance parameters, that one or more of the tenant addresses are being subjected to a DOS attack. The load balancer performs a mitigation operation to isolate the one or more tenant addresses being subjected to the DOS attack.

Abstract: The present invention extends to methods, systems, and computer program products for off loading load balancing packet modification. Embodiments of the invention can be used to offload the load of forwarding packets back to packet senders. Load balancers and/or the NAT devices can handle the first few packets of a connection to formulate connection mappings and then are removed from further communication for the connections. For example, a load balancer or NAT device makes the corresponding load balancing or the NAT decision based on a first packet and then informs the sender of the data of the decision. From then on, the sender can directly send the data to the receiver without having to go through the load balancer or NAT.
