Abstract: The present disclosure is directed to supporting multiple virtual LANs (VLANs) via a single tunnel between intermediary devices. A first intermediary device of a first data center on a first network receives, from a second intermediary device of a second data center on a second network, an encapsulated packet via a tunnel established between the first intermediary device and the second intermediary device. The first intermediary device comprising a plurality of network interfaces, each corresponding to a virtual LAN (VLAN) network of a plurality of VLAN networks. The first intermediary device detects that the encapsulated packet has been tagged with virtual LAN (VLAN) information by the second intermediary device identifies a VLAN network of the plurality of VLAN networks and transmits a packet of the encapsulated packet via the network interface corresponding to the identified VLAN network.

Abstract: Described herein is a method and system for distributing request and responses across a multi-core system. Each core executes a packet engine that further processes data packets allocated to that core. A flow distributor executing within the multi-core system forwards client requests to a packet engine on a core that is selected based on a value generated when a hash is applied to a tuple comprising a client IP address, a client port, a server IP address and a server port identified in the request. The packet engine selects a first IP address and a first port of the core, and determines whether a hash of a tuple comprising those values identifies the selected core. A modification is then made to the client request so that the client request includes a tuple comprising the first IP address, the server IP address, the first port and the server port.
