Data plane resource allocation

摘要

A method for allocating data plane resources. The method allocates segments of hardware data plane resources to individual domains. In particular, in one or more embodiments, a new domain data plane request may request multiple segments of hardware data plane resources. In response to the request, a segment is reserved for a domain by assigning a domain identifier of the domain to the segment. Thus, the domain may use the allocated segment.

1. A method for data plane resource allocation comprising:
receiving, for a domain, a new domain data plane request; selecting, to satisfy the new domain data plane request, a segment in each of a plurality of hardware data plane resources; reserving the segment in each of the plurality of hardware data plane resources by assigning a domain identifier of the domain to the segment; receiving a signal of a packet on a physical interconnect of a port; determining the domain identifier of the packet based on the domain identifier assigned to the segment having the port; adding, subsequent to the receiving the signal on the physical interconnect, the domain identifier to the packet; selecting the segment in at least a portion of the plurality of hardware data plane resources that is assigned the domain identifier; processing the packet using the segment in at least the portion of the plurality of hardware data plane resources; and removing, subsequent to the processing the packet using the segment, the domain identifier from the packet.
