What are service routers?

Service routers are the backbone of any network infrastructure. They are specialized devices that route data between different networks, ensuring that traffic is delivered reliably and efficiently. A service router provides a range of features and capabilities to meet the needs of diverse industries such as healthcare, finance, education, government, and more.

A service router can handle multiple types of connections simultaneously. It enables data transfer at high speeds without compromising quality or security. Cisco 3800 is an advanced level device among other options for service routers in the market today.

One significant benefit of using a service router like the Cisco 3800 is its ability to ensure network reliability even during peak usage times. Service routers provide load-balancing capabilities which allow them to distribute traffic evenly across various links on your network.

Moreover, modern-day businesses need reliable communication systems for remote workforces or employees working from different locations globally; hence they must invest in a powerful system like Cisco 3800 for optimal efficiency.

A Service Router plays a crucial role in keeping business operations running smoothly by providing secure connectivity between networks with fast routing speed while distributing workload evenly through load-balancing technology such as Cisco 3800 series devices.

Do you need a service router?

Service routers are designed for businesses that require constant and reliable access to the internet. If your business relies on the internet to operate, then a service router is essential.

A Cisco 3800 service router can handle large volumes of traffic while providing high-speed connectivity and enhanced security features that protect your network from cyber threats.

One of the key advantages of using a service router like Cisco 3800 is its ability to prioritize traffic based on application type or user identity. This ensures critical applications receive priority over less important ones, resulting in better performance across all network-connected devices.

Additionally, service routers allow for seamless integration between different networks such as LANs and WANs. This interconnectivity enables you to manage multiple locations with ease while maintaining consistent levels of security and performance throughout your organization.

If you’re looking for an efficient way to increase productivity within your business while keeping it secure from outside threats, investing in a Cisco 3800 service router might be exactly what you need.

Cisco 3800: An overview

The integrated services routing architecture of the Cisco 3800 Series is designed to embed and integrate security and voice processing with advanced wired and wireless services for rapid deployment of new applications, including application layer functions, intelligent network services, and converged communications.

The Cisco 3800 Series supports the bandwidth requirements for multiple Fast Ethernet interfaces per slot, time-division multiplexing (TDM) interconnections, and fully integrated power distribution to modules supporting 802.3af Power over Ethernet (PoE), while still supporting the existing portfolio of modular interfaces.

This ensures continuing investment protection to accommodate network expansion or changes in technology as new services and applications are deployed. By integrating the functions of multiple separate devices into a single compact unit, the Cisco 3800 Series dramatically reduces the cost and complexity of managing remote networks.

Cisco 3800: Features and Benefits

The Cisco 3800 Series helps companies operate securely in a networked economy and easily implement network services that will improve their business without impacting existing operations or degrading network performance. 

● This high-performance architecture is optimized for concurrent service deployment.
● This architecture offers increased default and maximum memory for future services growth.
● PVDM slots accommodate digital-signal-processor (DSP) modules for packet voice
● Enhanced chassis interfaces help enable unprecedented performance and service densities.
● Advanced service interfaces integrate applications directly into the router, without the need for
separate appliances:

◦ Network analysis module (NAM)-Integrated traffic monitoring helps enable application level
visibility into network traffic for remote troubleshooting and traffic analysis.
◦ Cisco Intrusion Prevention System (IPS) Module-The Cisco IPS Module provides the ability
to inspect all traffic traversing router interfaces (both inline and promiscuous mode); to
identify unauthorized or malicious activity such as hacker attacks, worms, or denial-ofservice attacks; and to terminate illegitimate traffic to suppress or contain threats.
◦ The Cisco Wide Area Application Services (WAAS) Network Module delivers application
acceleration and WAN optimization solution that accelerates the performance of any TCPbased application delivered across a WAN.

● Onboard DSPs-Integrated PVDMs support analogue voice, digital voice, conferencing,
transcoding, and securing Real-Time Transport Protocol (SRTP) media while enabling
network-module or AIM slots for switching, concurrent applications, content, and voice mail.
The DSPs help enable packet voice technologies, including VoIP protocols such as H.323,
Media Gateway Control Protocol (MGCP), and Session Initiation Protocol (SIP); voice over
Frame Relay; and voice-over ATM (including ATM Adaption Layer 5 (AAL5) and AAL2
adaptation layers).
● The platform offers scalability for centralized and distributed call processing:

◦ SRST with centralized Cisco Unified Communications Manager-Up to 730 phones
◦ Cisco Unity Express (CUE) voice mail-Up to 250 mailboxes
◦ Cisco Unified Communications Manager Express IP phones-Up to 250 IP phones
◦ Small to large branch connectivity-Up to 24 T1/E1 trunks
◦ Analog phones, fax machines, key systems, and conference stations-Up to 88 FXS ports
◦ Local or long-distance calling with the EVM module-Up to 48 foreign exchange offices (FXO)
or 32 Basic Rate Interface (BRI) ports

● Cisco IOS Software delivers customized features and applications, such as Tool Command
Language (TCL) and Voice Extensible Markup Language (VXML) support
● Secure calls are possible with Cisco Unified Communications Manager and Cisco IP phones
using the Cisco 3800:

◦ Offers standards-based, secure media and signalling authentication and encryption from IP
phone to IP phone, IP phone to analogue phone or public switched telephone network
(PSTN) gateway using IPSec, transport layer security (TLS), and Secure Real Time
Protocol (SRTP)

◦ Maintains channel capacity for medium- and high-complexity codecs

● Cisco IOS Software features offer support for identifying, preventing, and adapting to security
threats and maintaining a self-defending network, including IOS Firewall, Content Filtering,
Flexible Packet Matching (FPM), Dynamic Multipoint VPN, Group Encrypted Transport VPN
and SSL VPN.
