             JUNIPER NETWORKS, INC. REPORTS Q1'04 FINANCIAL RESULTS
          Q1'04 NET REVENUE $224.1M; GAAP EPS $0.08; NON-GAAP EPS $0.09

Sunnyvale, CA - April 21, 2004 -- Juniper Networks, Inc. (NASDAQ: JNPR) today
reported its results for the quarter ending March 31, 2004.

Net revenues for the first quarter were $224.1 million, compared with $157.2
million for the same period last year, an increase of 43 percent.

GAAP net income for the first quarter was $33.5 million or $0.08 per share,
compared with a GAAP net income of $3.7 million or $0.01 per share in the first
quarter of 2003. Non-GAAP net income, which excludes the amortization of
purchased intangibles and deferred compensation and the gain on the sale of
investments, was $36.4 million or $0.09 per share, compared with non-GAAP net
income of $6.3 million or $0.02 per share in the first quarter of 2003.

Cash provided by operations was $72.8 million for the first quarter, compared to
cash provided by operations of $12.4 million for the same period last year.
Capital expenditures and depreciation during the first quarter were $7.6 million
and $8.6 million, respectively.

NetScreen Technologies, which was acquired by Juniper Networks on April 16,
2004, had net revenues for the quarter ending March 31, 2004 of $93.5 million,
compared with $58.3 million for the same period last year, an increase of 60
percent. GAAP net loss for the quarter was $3.0 million or $0.03 per share,
compared with a GAAP net income of $5.9 million or $0.07 per share in the same
quarter of 2003. Non-GAAP net income, which excludes the amortization of
purchased intangibles and deferred compensation and merger related costs, was
$15.3 million or $0.15 per share, compared with non-GAAP net income of $13.0
million or $0.15 per share in the same quarter of 2003. Certain amortization of
purchased intangible assets and deferred stock compensation was reclassed from
cost of revenues to operating expenses to conform the presentation of
NetScreen's Statements of Operations to Juniper Networks' presentation. Cash
flow provided by operations for the quarter ended March 31, 2004 was $29.5
million, compared to cash provided by operations of $20.4 million for the
quarter ended March 31, 2003.

"The results posted by both Juniper and NetScreen as separate companies in the
first quarter were strong in all areas," said Scott Kriens, chairman and CEO of
Juniper Networks. "The strategy behind the decision to make this acquisition is
to leverage the strength of both companies, and these results are a key step in
executing our plan to extend Juniper's leadership position in the industry."
