Load balancing secure network traffic

A method, comprising:

• monitoring, using a processor, network traffic for one branch of a plurality of branches for an enterprise network;
• and
• splitting, using the processor, the network traffic of the one branch into a plurality of network segments based on a determination that the network traffic exceeds traffic capacity of at least one security processing node (SPN) of a plurality of SPNs using a network load balancer (NLB) in communication with a plurality of Network Processing Nodes (NPNs), wherein the one monitored branch is distributed to the plurality of SPNs via a plurality of tunnels, wherein the splitting of the network traffic of the one branch into the plurality of network segments comprises:
• determining that the network traffic of the one branch exceeds the traffic capacity of the at least one SPN, wherein the network traffic of the one branch is associated with at least one prefix;
• and
• in response to the determination that the network traffic of the one branch exceeds the traffic capacity of the at least one SPN, splitting the at least one prefix into a plurality of smaller prefixes, wherein the at least one prefix is broken into a first non-overlapping portion and a second non-overlapping portion.

A computer program product embodied in a non-transitory computer readable medium and comprising computer instructions for:

• monitoring network traffic for one branch of a plurality of branches for an enterprise network;
• and
• splitting the network traffic of the one branch into a plurality of network segments based on a determination that the network traffic exceeds traffic capacity of at least one security processing node (SPN) of a plurality of SPNs using a network load balancer (NLB) in communication with a plurality of Network Processing Nodes (NPNs), wherein the one monitored branch is distributed to the plurality of SPNs via a plurality of tunnels, wherein the splitting of the network traffic of the one branch into the plurality of network segments comprises:
• determining that the network traffic of the one branch exceeds the traffic capacity of the at least one SPN, wherein the network traffic of the one branch is associated with at least one prefix;
• and
• in response to the determination that the network traffic of the one branch exceeds the traffic capacity of the at least one SPN, splitting the at least one prefix into a plurality of smaller prefixes, wherein the at least one prefix is broken into a first non-overlapping portion and a second non-overlapping portion.
