Networking-tech company Juniper (JNPR) - Get Report will have its chance to shine when it reports earnings after the bell on Tuesday. 

But business is already tough for the company which faces competition from major industry players including Cisco (CSCO) - Get Report and Hewlett-Packard Enterprise (HPE) - Get Report , according to Jim Cramer, portfolio manager of the Action Alerts PLUS Charitable Trust, which holds Cisco. 

"Juniper is squeezed here," said Cramer in an interview at the New York Stock Exchange Monday morning. "This is Cisco's game, set, match. People don't realize that Cisco has moved to be a software company. I understand the switching business. I happen to also like HPE very much. I like what [chief executive officer] Meg Whitman is doing."

Cisco isn't set to report its recent quarter until mid-August, while Hewlett-Packard Enterprise has yet to announce when it will next report. 

Juniper is expected to report net income of $182.7 million, down nearly 13% from the year-ago quarter, according to Thomson Reuters consensus. Per-share profit is forecast to fall by a nickel to 35 cents. Revenue is forecast to decline by roughly 3% to $1.19 billion.

Shares of the Sunnyvale, Calif.-based business have fallen 13.4% in the year to date, compared to Cisco's 13% increase and the S&P 500's 5.8% gain. 

The stock rose 0.6% in trading on Monday.
