  We propose a simple protocol for Service Mesh management. The protocol
specification consists of the formats of messages, and the actions taken by
senders and recipients. The idea is that microservices of Cloud-Native
Application should be also involved in configurations of their communication
sessions. It does not interfere with the business logic of the microservices
and requires only minor and generic modifications of the microservices
codebase, limited only to network connections. Thus, sidecars are no longer
needed, which is in line with the current trends, e.g. Cilium Service Mesh.
This article presents the full formal specification of the proposed protocol
SSMMP/v1.1.
