Abstract
This description provides tools and techniques for detecting failures in IP networks using long packets. These tools may provide apparatus for monitoring several different communication paths between route processor modules within a given communications network. The apparatus selects one of the communication paths for connectivity testing, and sends both short and long test packets over the selected communications path. The apparatus then evaluates whether the test packets are transmitted successfully along the communication path.
Claims20
Apparatus comprising at least one computer-readable storage medium comprising computer-executable instructions stored thereon that, when executed by a general-purpose computer, transform the general-purpose computer into a special-purpose computer that is operative to:
- monitor a plurality of communication paths between a plurality of route processor modules within a communications network;
- select one of the communication paths for connectivity testing;
- send short and long test packets over the selected communication path;
- and
- evaluate whether the test packets are transmitted successfully along the communication path.
