Juniper Networks

Founded in 1996, Juniper Networks () is an american company specialized out of equipment of telecommunication. It produced solutions of network and safety. In partnership with Ericsson, Lucent, and Siemens AG, it provides solutions network on IP/MPLS.

May 1st 2006, Juniper Networks employed more than 4100 employees throughout the world.

Product range

The products of Juniper are composed of the families of routers T, M, E and J and of system SDX Service Deployment System.

T-series is large routers of backbone.
Mr.-series is multiservice routers of edge of network.
E-series is routers of edge generally being used for aggregation.
J-Series is small CPE.
NetScreen and the series SSG is firewall material.
Secure Access footbridges of VPN SSL.
IDP for the detection and the prevention of intrusion.
VF-series Session To border To control S.
WX and WXC - series accelerating WAN.
accelerating DX-series of applications.
UAC Unified Access Control.
AAA/802.1X RADIUS, 802.1X.

The routers of the series E uses the operating system JUNOSe. They were developed by the Unisphere company acquired by Siemens in 2002.

Routers of series M, T, and J use an architecture common software and the operating system JUNOS.

The series E, M and T utilisient ASIC for the packet switching. They can thus be used as terminals for multiple fiberoptics. The series J gathers less powerful routers but supports lines of flows all the same equal or lower than the DS3 (45 Mbits/s). This line of target product the off-set entities of large company and the equipment customer of service providers. With the autumn 2006, the series J was packed of a new range of modules making it possible particularly to improve the performances with new uses WAN (for example of the charts of services of encryption). In the same advertisement, Juniper indicates that he cooperates with the company Avaya to integrate his solution of telephony IP in the routers of the series J.

The firewalls NetScreen and Secure Services Gateways (SSG Series) utilisient the operating system ScreenOS. These machines have capacities of firewall and material encryption VPN. The firewall proposes also antivirus systems and anti intrusion to discharge the internal materials in the LAN.

The products Secure Access provide VPN based on SSL for users distant. This product comes was created by Neoteris that NetScreen acquired before its repurchase by Juniper.

Products IDP allow detection and the interception of traffic malicious network by using an analysis by étât.

Range of the routers M

The history of the routers in the range M:

M40 September 1998
M November 20th, 1999
M160 March 2000
M7i November 2003

In, 2007 this range aims at the following applications:

M5: small point of presence, large offices
M7i: idem and managed CPE.
M10: for points of presence more important, the M10i version offers a redundancy of CPU boards and food.
M20 and M40e: important points of presence
M160 and M320: hearts of Internet network, this last supporting 320 Gbps on the whole.

All these routers use the same operating system (JunOS), thus the functionalities are identical in all the range, the homogeneous proposed services and the reduced cost of exploitation. The difference lies in the capacity of the bottom of basket and the number of plug-in chart.

M7i take again the large range of charts PEAK available for M5 and M10. It comprises 4 ports to accommodate these charts. M10i comprises two routing engine and 8 ports, it comprises a chart HCM (High-Availability Chassis Manager) making it possible to withdraw hot charts.

These two routers use named charts “Routing Engine” (1 on M7i, 2 on M10i). This chart comprises the hard drive and the processor, there exists about it of two types named according to the speed of the embarked processor:

These charts can also have a slot PCMCIA Flash in option.

Range of the routers J

The series J left at the end of 2004, it shows the will of Juniper to open at the market companies handling less data. Indeed, Juniper proposes an interface of configuration Web: JWEB (later wide in option with the routers of the series M).

This series uses standard processors and do not have a ASIC. Thus, the processor manages the tables of services AND commutation.

The routers proposed are (in 2007):

J2300 (1U)
J4350
J6350

These the last two routers replace the precedents J4300 and J6300 with new processors allowing to multiply by four their performances. They are similar

J2300 occupies 1U and does not propose space to plug in additional charts. J4350 and J6350 make 2U, they make it possible to plug in 6 charts and are delivered basic with 4 Giga ports in frontage. The charts available for this series are PIM:

4 ports fast Ethernet
1 port giga Ethernet coppers
1 port giga Ethernet SFP (optical)

J6350 comprises 1 Go of extensible RAM with 2 Go, it has a compact flash of 256 Mo. One can associate a chart dedicated to the encryption to him.

History of acquisitions

Juniper was founded by Pradeep Sindhu, Dennis Ferguson, and Bjorn Liencres in February 1996 in California. It is moved in March 1998 in Delaware. Juniper becomes public on June 25th, 1999.

Juniper has since asset a certain number of companies:

Unisphere Networks, a subsidiary company of Siemens, in July 2002 for 585 million dollars.
NetScreen Technologies in April 2004 for 3,4 billion dollars.
Nexsi Systems (the intellectual property of the company)
Kagoor in April 2005 for 65,7 million dollars.
Redline and Peribit Networks in July 2005 for 337 million dollars.
Acorn Packet Solutions in October 2005 for 8,7 million dollars.
Funk Software in December 2005 for 122 million dollars.
