Abstract

Techniques for extending network elements to inspect, extract, and complement tracing information added to L7 flows by application distributed tracing systems. The techniques may include receiving a Layer-7 (L7) message of an L7 flow associated with a distributed application and determining that the L7 message includes tracing information. In some examples, the tracing information may be mapped to a marking that is to be included in a Layer 3 (L3) or Layer-4 (L4) packet carrying the L7 message, and the L3 or L4 packet including the marking may be sent to an L3 or L4 network element. In some examples, the L3 or L4 network element may be configured to utilize the marking to determine a network decision for the L3 or L4 packet.
