Architecture
The roteador 1841 is based on the Cisco 1700 Series routers. According to Cisco, the 1841 has aa five-fold performance increase, compared to the 1700 series of routers. The Cisco 1841 features one internal Advanced Integration Module (AIM) slot, which allows users to connect additional hardware-accelerated encryption modules. The router supports two high-speed WAN interface card (HWIC) slots, which increase its data capability to up to 800 Mbps. The router also comes with dual high-speed Ethernet LAN ports.
Scalability and Flexibility
Cisco 1841, like other Cisco products, offers a high degree of scalability and flexibility. The router can be connected with a wide range of other Cisco products, or modules, via LAN and WAN connectors and interface cards. According to Cisco, the cheap cisco 1841 supports more than 30 existing modules and interface cards, and, furthermore, is designed to support those that are expected to appear in the marketplace in the near future.
Security Features
The router is equipped with advanced integrated security features that are incorporated into what Cisco calls the Cisco Self defending Network. The Cisco Selfdefending Network provides tight coupling among security and routing services throughout the network. The cisco 1841 integrated services router price comes with a built-in firewall. The device also supports Triple Data Encryption Standard, or 3DES, Advanced Encryption Standard, or AES, 128, 192, and 256, and DES cryptology.

DoS Protection on Cisco 7600 Routers
The Cisco7600 is one of the most versatile High End routing machines. It is one of enterprise’s networking devices. If you take a look at Cisco website under the Routers Product Category, you will notice that the Cisco 7600 can be used in Data Centers, in Service Provider networks, in WAN aggregation or as Internet Edge router. In Service Providers can be used as Provider Edge (PE) in IP MPLS networks aggregating many Customer Edge (CE) router devices. Its modularity and high port capacity allows the 7600 to work as both Layer2 aggregation and as Layer3 high performance router.
In Service Provider networks one of the main concerns of network administrators is to protect the networking infrastructure from Denial of Service attacks. These DoS attacks are actually the most serious and popular security threat against Service Providers. buy used router Botnets are frequently the main source of such attacks. ICMP flooding, UDP flooding, spoofed addresses DoS, SYN attacks etc are a few examples of DoS or DDos (Distributed Denial of Service) attacks. Fortunately the Cisco 7600 router has many robust features and mechanisms to protect itself from such attacks.
In the company that I work (Service Provider) we have already implemented several security protection features on 7600 which are really effective against DoS attacks. A summary of the DoS protection mechanisms on 7600 follows below:
- Security Access Control Lists (ACL): Applied on interfaces to block traffic at Layer3/4 layers.
- QoS Rate Limiting: Using class-maps and policy-maps you can apply rate limiting to specific type of traffic (e.g ICMP)
- uRPF (unicast Reverse Path Forwarding): protects against spoofing attacks. sell cisco routers
- Traffic Storm Control: Protects against broadcast storm attacks.
- TCP Intercept: Protects against SYN attacks.
- Hardware-Based Rate Limiters: Work on PFC3 engines. These rate limiters protect the MSFC routing engine from various packets that can overload its CPU (configured with the mls rate-limit command)
- Control Plane Policing (CoPP): Again used for protection of the MSFC routing engine by applying rate limiting to packets that flow from the data plane to the control plane.
Of course in addition to the above you must not forget other important security mechanisms such as strong password policy, proper Authentication and Accounting, refurbished cisco router logging, SNMP security, Routing Protocols security (MD5 authentication in OSPF, BGP etc) etc. All of these technical issues must be based on a thorough and carefully written security policy.
Tips: If you need to know more about Cisco 7600 series, such as key features, specs, related software and price, or wannato buy cisco refurbished routers, you can visit router-switch.com to see more news and info of Cisco network equipment.
