+
+Agenda:
+
+ * General way of reconnection to existing sessions;
+ * Session restoration mechanisms architecture;
+ * The problems with reconnection mobile developers encountered in our last
+   project and proper ways to solve them;
+ * Handshake packet formats (for request and response) that will be used to
+   implement reconnection to existing sessions.
+
+Conclusions:
+
+ * To make packet numbers unique for every session, not connection like it was before;
+ * To send total count of packets sent and received by each side during the session
+   in handshake packet, like this:
+
+   ```javascript
+   { handshake:[0, 'appName'], session: ['sessionId', sent_count, received_count] }
+   ```
+
+   and answer
+
+   ```javascript
+   { handshake:[0], ok: [sent_count, received_count] }
+   ```
