Abstract

In providing packet forwarding policies in a virtual service network that includes a network node and a pool of service load balancers serving a virtual service, the network node: receives a virtual service session request from a client device, the request including a virtual service network address for the virtual service; compares the virtual service network address in the request with the virtual service network address in each at least one packet forwarding policy; in response to finding a match between the virtual service network address in the request and a given virtual service network address in a given packet forwarding policy, determines the given destination in the given packet forwarding policy; and sends the request to a service load balancer in the pool of service load balancers associated with the given destination, where the service load balancer establishes a virtual service session with the client device.

Claims22

Dependent claims

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.

A virtual service network, comprising:

a pool of service load balancers serving a virtual service associated with a virtual service network address;
and
a network node comprising at least one packet forwarding policy, each packet forwarding policy comprising a range of virtual service network addresses associated with a destination, wherein the network node:
receives a virtual service session request from a client device, the virtual service session request comprising the virtual service network address for the virtual service served by the pool of service load balancers;
compares 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, determines the destination in the packet forwarding policy;
and
sends 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.
