FILTER TABLES FOR MANAGEMENT FUNCTIONS
First Claim
Patent Images
1. A networking component comprising:
- an ingress port to receive a packet including a signature address;
a filter table to be used in Media Access Control (MAC) chaining, to contain mappings between signature addresses, service functions, and management functions, to identify corresponding service function chains, wherein the filter table is to store statistic information about the packet;
a controller to uniquely identify a management function corresponding to the signature address, and modify tables of packet signature addresses usable to modify the packet to cause the packet to be forwarded to the management function, wherein the controller is to update the statistic information about the packet.

Abstract
In accordance with examples disclosed herein, a filter table for Media Access Control (MAC) chaining contains mappings between signature addresses, service functions, and management functions, to identify corresponding service function chains. The filter table is to store statistic information about the packet. A controller is to uniquely identify a management function corresponding to the signature address, and modify tables of packet signature addresses usable to modify the packet to cause the packet to be forwarded to the management function. The controller is to update the statistic information about the packet.

12. A method, comprising:
-
receiving, at an ingress port, a packet including a signature address; mapping, by a filter table to be used in MAC chaining, between signature addresses, service functions, and management functions, to identify a corresponding service function chain; storing, by the filter table, statistic information about the packet; uniquely identifying, by a controller, a management function corresponding to the signature address; modifying, by the controller, tables of packet signature addresses usable to modify the packet to cause the packet to be forwarded to the management function; and updating, by the controller, the statistic information about the packet. - View Dependent Claims (13)

14. A non-transitory machine-readable storage medium encoded with instructions executable by a computing system that, when executed, cause the computing system to:
-
receive, at an ingress port, a packet including a signature address; map, by a filter table to be used in MAC chaining, between signature addresses, service functions, and management functions, to identify a corresponding service function chain; store, by the filter table, statistic information about the packet; uniquely identify, by a controller, a management function corresponding to the signature address; modify, by the controller, tables of packet signature addresses usable to modify the packet to cause the packet to be forwarded to the management function; and update, by the controller, the statistic information about the packet. - View Dependent Claims (15)
