The CISCO3945/K9 Cisco 3900 Series 3 Ports Integrated Services Module Router is designed with high-reliability features to ensure that it can operate under demanding conditions and provide a stable and dependable network service.
One of the key features for high-reliability is its support for hardware-based forwarding, which offloads the processing of packets from the CPU to specialized ASICs (Application Specific Integrated Circuits). This helps to reduce the load on the CPU, allowing it to handle more traffic and improve the overall performance of the router.
The router also has a modular design that allows for easy maintenance and upgrades, this feature helps to minimize downtime and reduce the need for extensive repairs. Additionally, the router supports various monitoring and management features, such as SNMP, NetFlow, and Cisco IOS Embedded Event Manager (EEM), that allow network administrators to monitor the health of the router and take corrective action if necessary.
Another feature that contributes to the high-reliability of this product is its support for advanced security features such as firewall and VPN capabilities, intrusion prevention, and content filtering. These features help to protect the network against a wide range of security threats, such as malware, hacking, and denial-of-service attacks.
Robust Security and Dynamic Quality
The CISCO3945/K9 Cisco 3900 Series 3 Ports Integrated Services Module Router is designed with robust security and dynamic quality features to ensure that it can provide a secure and high-quality network service.
In terms of security, this part supports advanced security features such as firewall, VPN capabilities, intrusion prevention and content filtering. These features help to protect the network against a wide range of security threats, such as malware, hacking, and denial-of-service attacks. The router also supports various security protocols, such as IPSec, SSL, and SSH, which help to secure the communication between the router and other devices on the network.
The router also supports Quality of Service (QoS) features that allow for the prioritization of different types of traffic, such as voice or video, over others. This helps to ensure that critical applications receive the bandwidth they need to function properly, even when the network is congested.
This product also supports dynamic quality features such as traffic shaping, congestion management, and link fragmentation and interleaving (LFI). These features help to improve the overall performance of the network by controlling the flow of traffic, reducing congestion, and improving the efficiency of the network.

Routers lead the line as the first line of network security in homes and offices. It prevents intrusion into a network while creating a firewall to provide the highest level of security on several network types. They are the best ways of keeping computer systems, network systems, and information contained in them safe from intrusion.
A router is designed to be more capable than several other network devices such as hubs or switches that can only carry out basic network functions. For instance, a hub only transfers data between network devices without analyzing or doing anything with those data. On the other hand, routers are able to analyze data sent between network devices. They can change the packaging of such data and send it over to a different network.
Routers are the perfect devices to share an internet connection between multiple computers in home networks. A router typically connects to the modem using a network cable. Router networking occurs via a WAN port or the internet. There are also wireless routers that connect to devices using different wireless standards.
The hardware inside these routers allows them to cope with several network use at the same time. Many of these routers come with dual-core and quad-core processors. These processor options allow them to handle lots of data more effectively. Users can use their Wi-Fi routers for activities such as video streaming, online gaming, data backups, and more. Even while carrying out those operations, the routers perform at the highest levels.
Users will get routers that broadcast wireless signals over two frequencies (for dual-band) or more (for tri-band and others). These routers run at frequencies that can cover a wide expanse of area. They are not congested and are perfect for office buildings, homes, and large enterprises. Clients will find routers that emit their signals between 2.4 GHz and 5 GHz.
Built-in Security Features
These router networking devices also come with security features such as device quarantine, firmware updates, automatic updates, and more. The features allow them to provide network-level protection against attacks. With these features, cyber criminals will be unable to infiltrate home networks.
Types of Routers
There are several types of routers that users can benefit from. Some of them include:
- Core Routers. These are the types used by Internet Service Providers. They are the fastest and most powerful types. They sit at the center of the internet and forward data through the main fiber Optics.
- Wireless Routers. These work in a similar manner as a home or business LAN. However, they give room for better mobility for laptops, tablets, and other portable devices. These types offer transmission over short distances.
- Enterprise Routers. These are the types employed by large companies. Organizations use enterprise routers to connect their networks to these core routers.
- Branch Routers. These types connect an enterprise's remote offices to its Wide Area Network (WAN). They come with improved features such as wireless LAN management, time-division multiplexing, WAN acceleration, and more.
- Edge Routers. These are the most commonly used types in homes and small businesses. They are low-capacity devices that connect to the public internet or private WAN, or external LAN.
- Logical Routers. They function similarly to hardware to create several network routes.
