commons-networking

Commons networking related utils.

Note: This is not an official Cisco product.

Features

• SSE (Server-sent Events) client
• GNMI Utils

SSE client

SSE client implementation based on Java 11 HttpClient.
Server-Sent Events (SSE) is a server push technology enabling a client to receive automatic updates from a server via HTTP connection.
The Server-Sent Events EventSource API is standardized as part of HTML.
It is used for unidirectional server to client events, as opposed to the full-duplex bidirectional WebSockets.
One of the use cases is by IEFT Netconf/Restconf protocols: IETF reference

Example usage

SSEClientTest

EventHandler eventHandler = eventText -> { events.add(eventText); };
SSEClient sseClient = SSEClient.builder().url(url).eventHandler(eventHandler)
	.build();
sseClient.start();

GNMI Utils

Parsing string representation of GNMI paths.
Following:
Representing GNMI paths as strings

This is useful for device collection / GNMI path configuration.

Example usage

GNMIUtilsTest

String gnmiPathStr = "openconfig-interfaces/interfaces/interface[name=Ethernet/1/2/3]/state";
Path parsedPath = GNMIUtils.parseGNMIPathStr(gnmiPathStr);
