Claim:
1. A method for providing forwarding policies in a virtual service network, the virtual service network comprising a network node and a pool of service load balancers serving a virtual service associated with a virtual service network address, comprising: receiving a virtual service session request from a client device by the network node, the virtual service session request comprising the virtual service network address for the virtual service served by the pool of service load balancers, wherein the network node comprises at least one packet forwarding policy comprising a range of virtual service network addresses associated with a destination; comparing by the network node the virtual service network address in the virtual service session request with the range of virtual service network addresses in each packet forwarding policy; in response to finding that the virtual service network address in the virtual service session request is included in the range of virtual service network addresses in a packet forwarding policy, determining the destination in the packet forwarding policy by the network node; and sending the virtual service session request to a service load balancer in the pool of service load balancers associated with the destination, wherein the service load balancer establishes a virtual service session with the client device.
