§ 1.2.1 Networks, Inter-Networks, and the Need for Sampling
§ 1.2.2 Challenges to Gathering Data for Network Analysis
In the following, an exemplary environment in which the present invention may operate is described in § 4.1. Then, functions that may be performed by the present invention are introduced in § 4.2. Then, exemplary operations, apparatus, methods, message formats and data structures that may be used to effect those functions are described in § 4.3. Thereafter, an example illustrating certain operations of the invention in the context of a particular embodiment, is described in § 4.4. Finally, some conclusions regarding the present invention are set forth in § 4.5.
Exemplary methods that may be used to effect these operations, as well as exemplary data structures that may be used, or created, by these operations, are described in § 4.3.2.1 below. Then, systems on which these operations may be effected are described in § 4.3.2.2 below.
As can be appreciated from the foregoing disclosure, and the operating example set forth in § 4.4, the present invention can specify a next hop interface for samples. The present invention can further suppress sampling and/or drop samples is the specified next hop interface becomes unstable. Using hardware (e.g. registers) to hold a next hop interface index and a next hop interface state, sampling can be done at high speeds (e.g., line rate). By managing the contents of these hardware registers using software, flexible and intelligent control of samples is achieved.
