How to Select a Right Router for Home or Business

No matter which group you belong to or stay with? If you want to connect outside world through cisco 1841 configuration computer, router is an essential element of modern home and business networks.Arouter lets your computer connect to the Web to read your favorite Web sites, check e-mail, IM friends, or teleconference with colleagues….

When we speak of routers, I usually think of Cisco---a network giant, even though so many others such as Nortel, D-link, Netgear, etc. Because Cisco router is considered as the top choice while choosing a router for home or office, and the more important is that Cisco System offer SOHO, small, medium and large-sized offices or enterprises with different types of routers to meet their different needs.

As we known, the popular Cisco router in the market are Cisco 800 series, cisco 1841 picture, Cisco 1900 series, Cisco 2800, Cisco 2900, Cisco 3800, 3900, 7200 and 7600, etc.(for small to large businesses), also Cisco Linksys-E series for home.

More choice, harder to select the very one for family or for enterprise. But it doesn’t matter if you evaluate and weigh the following eightcriteria that can help you figure out which router best fits your needs.

Your Usage and Router’s Performance
For home or for office (small or large size?), first be clear about it. Different demands require different performance of router. For example, choosing a one for family, you may just want to surf on the internet, no need of a router as a heavy-duty gamer or a small business, Cisco Linksys-E series will fit you. Because you know the more expensive the router, the more features it will contain. However, it doesn’t necessarily buy a higher performance router. And for business, especially for large or head offices, router’s higher performance and safety is vital elements which must be considered while buying. Cisco 1800, 1900, 2800, 2900(for small to medium-sized business or enterprise branch office, Cisco 3800, Cisco 3900, Cisco 7200, Cisco 7600(for medium to large-sized business and enterprise head office), these types can meet companies’ various requirements…

Expandability
The router usually has a default number of interfaces—but some routers, such asthe 3600 series, have none. So, pay attention to the number of interfaces youcan add on top of the default.

Router’s Integrated Services
This refers to functionality supported by a router that previously required separate boxes. For example, a 16- or 32-port switching module in a router negates the need for an Ethernet switch; having a firewall, VPN server, and IDS/IPS sensor in a router can negate the need for a firewall, VPNconcentrator, and dedicated IDS/IPS appliance.

Support and Reliability
Cisco routers are traditionallyreliable, and cisco 1841 configuration guide is always offering a high level of support. When purchasing a router, you will have various levels of support options. Select the best level for your organization.Of course, using these features in your decision-making process requires some research. You could peruse the Cisco Routers Product Portfolio, scan through the specifications, and select the router yourself.Or, you could also use the criteria above to work with are seller or directly with Cisco to determine which routers offer the features you need.

Warranties
Router manufacturers always provide a warranty package together with their equipment. The length and terms of these warranties vary widely. A better warranty may indicate a manufacturer more committed to support their products, while a lesser warranty could indicate a somewhat lesser standard of product quality or reliability. Always consider router warranties when making your purchase decision.

Router’s Cost
Router manufacturers or router suppliers (like Cisco router supplier) sometimes offer rebates or other discounts from the full retail price of their routers. So you can buy a suitable router at a very great price while router is at a big discount. (Routerswitch.com, hardware.com, often have big discount for hot routers, like Cisco 1800, Cisco 1900, Cisco 2800, Cisco 2900, etc.

Actually, besides considering router’s basic function, performance, quality and style, you must notice router’s price. So you’d better make a comparison among different routers in order to choose a highly efficient and cost-effective one.

DoS Protection on Cisco 7600 Routers

The Cisco router 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.
