How to choose an enterprise-level Access Router

For many small and medium enterprises, the role of routers is becoming more and more important. So I have studied how enterprise users can correctly select enterprise-level access routers. Here I will share with you, I hope it will be useful to you. Core Routers and enterprise-level access router edge routers ).

Enterprise-level access routers are positioned to connect users to the Wan by means of LAN. There are still great differences between LAN and WAN technologies, and Edge Routers shoulder various responsibilities, simply put, it is necessary to meet various business needs of users, from simple networking to complex multimedia and VPN services.

Enterprise-level access routers are generally used by enterprise branches. For simple information transmission, such as mail-oriented, some key services do not need to be transmitted, for example, for users who carry voice and video, virtual leased line services, and remote data backup, some basic enterprise-level access routers are competent, so they do not need to buy high-price premium products ". However, the situation is not that simple for users who require their branches to implement their key businesses, such as foreign companies, industry users, and large enterprises, in addition to traditional data transmission and Packet Exchange functions, network devices are required to support data classification, priority control, user identification, fast recovery, and other features, this requires that enterprise-level access routers be "intelligent ".

Specifically, QoS capabilities, multicast technology, security, and management are required. At the same time, with the development of voice applications, whether or not to support voice functions depends on your application. The following describes several enterprise-level access routers. The Cisco 1841 integrated enterprise-level access router is one of the Cisco 1800 series Integrated Multi-Service routers. It can intelligently embed data, security, and wireless technology into the same system, it can provide secure data access applications at wire speed, so that key business applications can be quickly and securely provided to SMEs and small branches.

The Cisco 1841 router utilizes the modular features of AIM, the new high-speed WAN Interface Card HWIC) and VWIC, allowing you to use multiple connection methods. In addition, it supports more than 30 existing 1700 series WAN interface cards only in the WIC/VIC/VWIC data mode) to achieve investment protection. Enterprises can reduce costs, because only one Cisco 1841 instance can be deployed to provide multiple functions, for example, DSL broadband access, routing, LAN switch, firewall, VPN, IPS, wireless LAN technology, and QoS, which is generally executed by independent devices, provided by integrated redundant links.

The Cisco 1841 modular architecture is specifically designed to meet the needs of small and medium-sized enterprises, small enterprise branches, and service providers for managing applications for wire speed concurrent services. The Cisco 1841 router provides a variety of concurrent services for small and medium-sized enterprises and small enterprise branches securely, quickly, and with high quality. The Cisco 1841 enterprise-level access router provides hardware-based embedded encryption supported by optional Cisco IOS software security images, and further improves the VPN performance through an optional VPN acceleration module.

At present, many companies have high security and multi-integration service requirements for router products. The Cisco 1841 router integrates the functions of multiple independent devices into a single, small, and more intelligent solution that allows remote management. By providing integrated services and excellent modular density and high performance, the Cisco 1841 Enterprise Access Router provides security, versatility, scalability, and flexibility for small and medium-sized enterprises, small enterprise branches, and service supplier customer edges for multiple applications. It can meet the needs of current and future enterprises for the highest return on investment.
