EXHIBIT 2.1

                      AGREEMENT AND PLAN OF REORGANIZATION

      This Agreement and Plan of Reorganization (the "Agreement") is made and
entered into as of November 11, 2001, among Juniper Networks, Inc., a Delaware
corporation (the "Company") and Pacific Broadband Communications, Inc., a
Delaware corporation ("PBC").

                                    RECITALS

A. Upon the terms and subject to the conditions of this Agreement, PBC and the
Company intend to enter into a transaction whereby PBC will merge with and into
the Company.

B. The consideration will be in the form of the Company's common stock as
provided herein.

C. The parties intend, by executing this Agreement, to adopt a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended (the "Code") to the maximum extent possible.

                                   AGREEMENTS

The parties hereby agree as follows:

1. TRANSACTION.

      1.1 ACQUISITION. The Company will acquire 100% of the outstanding shares
of stock of PBC. PBC will merge with and into the Company (the "Merger") in a
straight merger, with the Company as the surviving corporation. Except for
stockholders of PBC holding Dissenting Shares (as such term is defined in
Section 2.4 herein), the stockholders of PBC will receive shares of the common
stock of the Company, par value $.00001 per share (the "Shares"), as provided in
Section 1.2 below.

      1.2 EXCHANGE RATIO.

            1.2.1 COMMON STOCK EXCHANGE RATIO. The number of Shares to be
received by each PBC stockholder holding shares of PBC common stock shall be
determined by multiplying the number of shares of PBC common stock held by such
stockholder by the Common Stock Exchange Ratio. The "Common Stock Exchange
Ratio" is defined as the quotient obtained by dividing (i) the quotient obtained
by dividing $73,000,000 by the "Juniper Per Share Price" (as defined below) by
(ii) the aggregate number of "PBC Common Securities" (as defined below). Each
holder of PBC issued and outstanding shares of common stock who does not demand
appraisal rights in accordance with Delaware Law or California Law, shall
receive the number of Shares equal to the number of Shares determined by
applying the Common Stock Exchange Ratio as defined in the preceding sentence.
In utilizing the Common Stock Exchange Ratio to calculate the amount of stock
consideration or the number or exercise price for option shares, all share
amounts will be rounded down to the nearest whole number and all dollar amounts
will be rounded up to the nearest cent.

            1.2.2 SERIES A EXCHANGE RATIO. The number of Shares to be received
by each PBC stockholder holding shares of PBC series A preferred stock shall be
determined by multiplying the number of shares of PBC series A preferred stock
held by such stockholder by the Series A Exchange Ratio. The "Series A Exchange
Ratio" is defined as the quotient obtained by dividing (i) the quotient obtained
by dividing $9,000,000 by the "Juniper Per Share Price" by (ii) the aggregate
number of "PBC Series A Preferred Securities" (as defined below). Each holder of
PBC issued and outstanding shares of series A preferred stock who does not
demand appraisal rights in accordance with Delaware Law or California Law, shall
receive the number of Shares equal to the number of Shares determined by
applying the Series A Exchange Ratio as defined in the preceding sentence. In
utilizing the Series A Exchange Ratio to calculate the amount of stock
consideration or the number or exercise price for option shares, all share
amounts will be rounded down to the nearest whole number and all dollar amounts
will be rounded up to the nearest cent.

            1.2.3 SERIES B EXCHANGE RATIO. The number of Shares to be received
by each PBC stockholder holding shares of PBC series B preferred stock shall be
determined by multiplying the number of shares of PBC series B preferred stock
held by such stockholder by the Series B Exchange Ratio. The "Series B Exchange
Ratio" is defined as the quotient obtained by dividing (i) the quotient obtained
by dividing $53,000,000 by the "Juniper Per Share Price" by (ii) the aggregate
number of "PBC Series B Preferred Securities" (as defined below). Each holder of
PBC issued and outstanding shares of series B preferred stock who does not
demand appraisal rights in accordance with Delaware Law or California Law, shall
receive the number of Shares equal to the number of Shares determined by
applying the Series B Exchange Ratio as defined in the preceding sentence. In
utilizing the Series B Exchange Ratio to calculate the amount of stock
consideration or the number or exercise price for option shares, all share
amounts will be rounded down to the nearest whole number and all dollar amounts
will be rounded up to the nearest cent.

            1.2.4 "JUNIPER PER SHARE PRICE" shall mean the average of the
closing price of the common stock of the Company for the 10 trading days
immediately preceding and including the date of this Agreement.

unvested), all other shares that are reserved for issuance under any stock
option plans, including the Additional Employee Shares (as defined below).

            1.2.6 "PBC SERIES A SECURITIES" shall mean all outstanding shares of
series A preferred stock of PBC.

            1.2.7 "PBC SERIES B SECURITIES" shall mean all outstanding shares of
series B preferred stock of PBC.

            1.2.8 "ADDITIONAL EMPLOYEE SHARES" shall mean the 3,335,690 shares
of PBC common stock that remain unissued out of the common stock currently
reserved for issuance under the PBC 2000 Stock Incentive Plan.

            1.2.9 "EARNOUT SHARES" shall mean a number of Shares calculated by
dividing $59,000,000 by the Juniper Per Share Price.

      1.3 ADDITIONAL PAYMENTS. The following payments shall be made at the
Effective Time:

            1.3.1 $5,000,000 shall be paid to Raza Foundries, Inc. in the form
of common stock of the Company. The number of shares to be delivered to Raza
Foundries, Inc. hereunder shall be calculated by dividing $5,000,000 by the
Juniper Purchase Price.

            1.3.2 $1,420,310 shall be paid to Bowman Capital and its affiliates
in the form of common stock of the Company. The number of shares to be delivered
to Bowman hereunder shall be calculated by dividing $1,420,310 by the Juniper

be assumed by the Company. The number of shares and the exercise price of such
PBC options shall, except as otherwise provided herein, be adjusted in
accordance with the Exchange Ratio (the number of shares shall be multiplied by
the Exchange Ratio and the exercise price per share shall be divided by the
Exchange Ratio). Except as otherwise provided in this Agreement, the original
vesting schedules of the converted and assumed options shall be retained and the
options shall have the same

      converted into the right to receive such number of Shares as determined by

Delaware Law or California Law, as the case may be. Notwithstanding the
foregoing, if any holder of shares of PBC common stock who demands appraisal of
such shares under Delaware law or California Law shall effectively withdraw or

except with the prior written consent of the Company or as may be required by
applicable law, voluntarily make any payment with respect to any demands for
appraisal of PBC common stock or PBC preferred stock, as the case may be, or

Dissenting Shares shall be made by PBC or the Company as the case may be.

      2.5 SURRENDER OF CERTIFICATES; ISSUANCE OF NEW CERTIFICATES. The holders
of the PBC share certificates shall surrender such certificates at the Closing.
The Company shall issue, through its transfer agent, Norwest Shareowner Services
(the "Transfer Agent"), shares of the Company's common stock in the amounts set
forth and as directed on Schedule 2.5 which schedule shall be agreed upon by PBC
and the Company prior to Closing and shall deliver certificates reflecting such
shares within 30 days after the Closing. The Shares issued in connection with
the Merger will be issued in a transaction exempt from the registration
requirements of the Security Act of 1933 (the "Securities Act") by reason of
Section 4(2) thereof and as such will be deemed "restricted securities" within
the meaning of Rule 144. Notwithstanding the foregoing, the Company shall
register the Shares pursuant to Section 1.4 herein.
