juniper NETWORKS ATASHEET J SERIES SERVI ROUTERS J2320, J2350, J4350, AND J635 Product Description Enterprises are faced with a number of challenges and opportunities by converging voice, video and data to one network. This consolidation of network elements reduces cost by easing deployment of SIP enabled VoIP, real-time high-definition Telepresence and standardizing on a consistent infrastructure network operating system like Juniper Networks® Junos® operating system. These new technologies improve; customer relations, interactions with suppliers, and employee productivity. This mission-critical multi-media network must be always on and always available. To accomplish this, fully integrated stateful security is a key requirement, not merely forwarding packets without regard to the intended application or individual user session. Junos OS provides the high-performance networking infrastructure that helps enterprises implement key initiatives that: Integrates routing, firewalling and VPN into one best in class secure router. By securing an enterprise's mission critical information and protecting the network from vulnerabilities and attack, the Juniper Networks J Series Services Router offers a combination of features that increases productivity and reduces costs. With Junos OS release 9.6, the J Series enhances these features with Unified Threat Management, consisting of antivirus, antispam, Web filtering and intrusion prevention system. These advanced security features can eliminate a standalone appliance and be applied with a software key. Օ Minimizes the cost of installing and operating a network by deploying J Series. With the modular, protected mode design of Junos OS and the rigorous Junos OS development and testing process, there are fewer system process failures. The single code source of Junos OS makes the qualification of new releases across the network much simpler. In addition, superior configuration management reduces human errors that could lead to network downtime. Whether you have an enterprise network or a service provider looking for customer premise equipment for an MPLS or IP network, the J Series offers a mix of features that excel at both. By leveraging Junos OS, the J Series can be deployed at medium to large sites and the wide range of interfaces scales the bandwidth as necessary for today's real time communications Product Overview Juniper Networks J Sries Services Routers extend enterprise applications and deliver reliable connectivity to remote offices with a powerful blend of high-performance network protection and advanced services. J Series Services Routers leverage the modular Junos OS and Juniper's rich product and partner portfolio to consolidate market leading security, application optimization, and voice capabilities onto a single, easy to manage platform. Our innovative security approach inseparably integrates routing and firewalls for exceptional performance. Available options, including integrated Juniper Networks application acceleration with the ISM200 Integrated Services Module, and integrated voice gateway technology from Avaya, make the J Series the ideal choice for closing the distance between central resources and remote locations. 1

Features and Benefits Secure Routing Should you use a router and a firewall to secure your network? By building the branch J Series Services Routers with best-in-class routing and firewall capabilities in one product, enterprises don't have to make that choice. Why forward traffic if it's not legitimate? J Series for the branch checks the traffic to see if it is legitimate, and only forwards it on when it is. This reduces the load on the network, allocates bandwidth for all other mission-critical applications, and secures the network from hacking. The main purpose of a secure router is to provide...

Session-Based Forwarding Without the Performance Hit In order to optimize the throughput and [atency of the combined router and firewall, Junos OS implements session-based forwarding, an innovation that combines the session state information of a traditional firewall and the next-hop forwarding of a classic router into a single operation. With Junos OS, a session that is permitted by the forwarding policy is added to the forwarding table along with a pointer to the next-hop route. Established sessions have a single table lookup to verify that the session has been permitted and to find the next...
