METHOD AND APPARATUS FOR NETWORK FUNCTION CHAINING
First Claim
1. A method performed by a host device for directing a message through a network function, the method comprising:
- receiving, at the host device, a first received message including a first identification of a first network function;
removing the first identification of the first network function from the first received message to create a first modified message; and
transmitting the first modified message to a first network function device for performance of the first network function with respect to the first modified message.

Abstract
Various exemplary embodiments relate to a method, network node, and non-transitory machine-readable storage medium including one or more of the following: receiving, at the host device, a first received message including a first identification of a first network function; removing the first identification of the first network function from the first received message to create a first modified message; and transmitting the first modified message to a first network function device for performance of the first network function with respect to the first modified message. Various embodiments are described wherein: the first received message includes a bitmap including a plurality of bit positions respectively corresponding to a plurality of network functions, and the first indication of a first network function comprises a bit within the bitmap at a bit position corresponding to the first network function.

8. A host device for directing a message through a network function, the host device comprising:
-
a network interface; a memory storing a switch configuration; and a processor in communication with the network interface and memory, the processor being configured to; support a plurality of virtualized devices assigned to a respective plurality of slots, and implement a virtualized switch, wherein the switch is configured to; receive, via the network interface, a first received message including a first identification of a first slot of the plurality of slots, remove, based on the switch configuration, the first identification of the first slot from the first received message to create a first modified message, and transmit the first modified message to a first virtualized device supported by the first slot. - View Dependent Claims (9, 10, 11, 12, 13)
