Abstract
A services processor includes an editing unit, which performs various functions for editing data packets, such as packet creation, packet encapsulation, and packet replication.
Claims6
A method for creating a data packet in a services processor from a packet template, the method comprising:
- creating an image of the packet template in an associated memory, the image having fields corresponding to a data packet to be created;
- initializing the fields of the image;
- and
- copying the image to a cache memory for use by the services processor.
A services processor for creating a data packet in a services processor from a packet template, the services processor encoded with instructions for:
- creating an image of the packet template in an associated memory, the image having fields corresponding to a data packet to be created;
- initializing the fields of the image;
- and
- copying the image to a cache memory for use by the services processor.
A method for adding an encapsulation to a data packet, the data packet associated with a packet context in a services processor wherein the packet context includes a set of encapsulation pointers, the method comprising:
- retrieving an encapsulation template that defines one or more encapsulation pointers;
- and
- copying the encapsulation pointers from the encapsulation template into the packet context for the data packet.
A services processor for adding an encapsulation to a data packet, the services processor encoded with instructions for:
- retrieving an encapsulation template that defines one or more encapsulation pointers;
- and
- copying the encapsulation pointers from the encapsulation template into the packet context for the data packet.
A method for replicating a data packet, the data packet associated with a packet context in a services processor, the method comprising:
- sending a processed data packet and a switch to a scheduler for output, wherein the switch indicates whether the processed data packet is to be replicated;
- and
- responsive to the switch,
- making a copy of the data packet in an associated memory, queuing the original or the copied data packet for output, and continuing to process the non-queued data packet in the packet context.
A services processor for adding an encapsulation to a data packet, the data packet associated with a packet context in a services processor wherein the packet context includes a set of encapsulation pointers, the services processor encoded with instructions for:
- retrieving an encapsulation template that defines one or more encapsulation pointers;
- and
- copying the encapsulation pointers from the encapsulation template into the packet context for the data packet.
