The picture shows a Su 30 MKI, fitted with Knirti SAP 518 ECM pods on the wingtips and the Knirti SAP 14 jamming pod on the centerline weapon station. With these pods the Flankers can be used for similar EW roles like the F18 Growler.

Here a model of MKI with these pods and a possible weapon load shown at Maks 2009:
Some more infos and pics about the pods and a simulation of Su 35BM (at the end of the article, Sukhoi Su-35BM / Su-35 'Deep Modernisation' Manufacturer Video), that shows how these pods will be used. The Video is also showing the Novator R-100 missile and the Klimov S117 engine and could give a hint about the MKI upgrades:
