Description
Cisco ISR, or Cisco Integrated Services Router, is a family of routers designed for small to medium-sized businesses, as well as enterprise branch offices. These routers offer a wide range of services, including routing, security, voice, wireless, and application services, all in a single device. The Cisco ISR provides a highly secure, scalable, and reliable infrastructure for businesses to run their critical applications.
How it Works
The Cisco ISR is a modular router, meaning that it can be customized to meet specific business needs. It is built on Cisco’s IOS operating system, which provides a familiar interface for network administrators. The router is designed to be highly scalable, allowing businesses to add more modules and services as their needs grow.
Routing Services
The Cisco ISR provides a wide range of routing services, including static routing, dynamic routing, and policy-based routing. Static routing allows network administrators to manually configure the routing table, while dynamic routing protocols such as OSPF, EIGRP, and BGP allow routers to exchange information and dynamically update the routing table. Policy-based routing allows administrators to apply different policies to different types of traffic, such as prioritizing voice traffic over data traffic.
Security Services
The Cisco ISR provides a comprehensive set of security services, including stateful firewall, VPN, intrusion prevention, and content filtering. The stateful firewall provides protection against unauthorized access to the network, while the VPN allows remote workers to securely connect to the network. Intrusion prevention detects and blocks attacks, while content filtering blocks access to certain websites and applications.
Voice Services
The Cisco ISR provides integrated voice services, allowing businesses to run voice over IP (VoIP) applications. The router supports a wide range of voice codecs, including G.711, G.729, and G.729a. It also supports voice quality monitoring and advanced call control features.
Wireless Services
The Cisco ISR provides integrated wireless services, allowing businesses to deploy wireless networks. The router supports a wide range of wireless standards, including 802.11a/b/g/n/ac. It also includes advanced features such as wireless intrusion prevention and location-based services.
Application Services
The Cisco ISR provides application services, allowing businesses to run a wide range of applications. The router supports a wide range of protocols, including HTTP, FTP, SMTP, and DNS. It also includes advanced features such as application acceleration and load balancing.
