A method for link aggregation of a plurality of communication links, performed in a communication arrangement, the method comprising; obtaining a data segment to be transmitted, identifying a preferred communication link out of the plurality of communication links for transmission of the data segment, and, if the preferred communication link is not available for transmission of the data segment within a current time period, identifying an alternative communication link out of the plurality of communication links different from the preferred communication link, fragmenting the data segment into at least a first fragment and a second fragment, attaching a fragment header to each of the first and second fragments, each fragment header being configured to identify the respective fragment as a fragment belonging to a data segment, and transmitting the first fragment over the alternative communication link.

According to an embodiment of a first aspect of the invention, there is provided a distributed network comprising a plurality of subnets. Each of the plurality of subnets comprises a plurality of nodes. The network is configured to run a set of computational units and to assign each of the computational units to one of the plurality of subnets according to a subnet-assignment, thereby creating an assigned subset of the set of computational units for each of the subnets. The network is further configured to run on each node of the plurality of subnets the assigned subset of the computational units and to replicate the assigned subsets of the computational units across the respective subnets. The network is further configured to exchange unit-to-unit messages between the computational units via a messaging protocol based on the subnet-assignment.

Further aspects of the invention relate to a corresponding computer-implemented method, a node, a computer program product and a software architecture.

Some embodiments of the invention provide novel methods for providing a stateful service at a network edge device (e.g., an NSX edge) that has a plurality of north-facing interfaces (e.g., interfaces to an external network) and a plurality of corresponding south-facing interfaces (e.g., interfaces to a logical network). In some embodiments, each interface associated with a different bridge calls a service engine based on identifiers included in data messages received at the interface. Each data message flow is associated with a particular identifier that is associated with a particular service engine instance that provides the stateful service. In some embodiments, the interface that receives a data message identifies a service engine to provide the stateful service and provides the data message to the identified service engine. After processing the data message, the service engine provides the data message to the egress interface associated with the ingress interface.

A system and a method of establishing seamless remote access VPN connections are described. For establishment of a VPN connection for a user device, a cluster leader of a cluster of controllers identifies an active controller and a standby controller, based on network load of each controller of the cluster of controllers. An active VPN connection is established between the user device and the active controller and a standby VPN connection is established between the user device and the standby controller. The standby VPN connection is utilized in place of the active VPN connection during failover of the active controller. Because information of an active session is regularly shared by the active controller to the standby controller, the standby controller can seamlessly resume the active session during failover of the active controller.
