Abstract
The disclosure herein describes a system, which provides service switching in a datacenter environment. The system can include a service switching gateway, which can identify a service tag associated with a received packet. During operation, the service switching gateway determines a source client, a requested service, or both for the packet based on the service tag, identifies a corresponding service portal based on the service tag, and forwards the packet toward the service portal. The service switching gateway can optionally maintain a mapping between the service tag and one or more of: a source client, a required service, the service portal, and a tunnel encapsulation. The service switching gateway can encapsulate the packet based on an encapsulation mechanism supported by the service portal and forward the packet based on the mapping.
