Importance of Broadband Router Functions

It is important to say that the Broadband Router kernel is not strong enough. This is correct, but isn't it enough for the vrocpu CPU? Apparently not! It is equally important that the router functions are complete and can meet the needs of specific applications. This is often overlooked, especially for small and medium enterprises and Internet cafe owners who have created a network.

For building a building, it is of course very important to produce excellent housing, good reinforced cement, and good building materials. However, it is necessary to have outstanding construction quality and reasonable structural design. Building materials are like the previously mentioned vro hardware such as processor and memory. The construction quality is embodied by the engineer's design capability, while the structure design is like the software function of the vro. Building a house with inferior building materials must produce bean curd residue. Building a good building material can be built without seeing it. The sound insulation effect of the building, the waterproof performance of the exterior wall, and the shockproof performance depend on the building materials and construction quality for decades or hundreds of years. However, whether the room layout is reasonable, whether the green area is excellent, or even the building interval, house type lighting, and the height of each floor, etc, it also has a direct impact on which users are attracted to purchase and which ones are suitable for purchase. In the same sense, the processor level is not enough, the response speed is low, and the corresponding data processing capability is insufficient. The memory capacity is not enough to occupy more processor resources, reducing the process processing speed and failing to get a good router product. However, if engineers do not develop practical and useful functions, they will not be able to solve actual problems and bring more value to the end users. In fact, the design capability of the router software not only reflects the stability, compatibility, operation efficiency, and the capabilities of the product, but also provides different practical functions that can be better suited to the customer groups of the product.

Based on the function of Broadband Router, this paper takes TP-LINK enterprise-level Broadband Router TL-R480T as an example to briefly introduce three special functions of TL-R480T: Port image, bandwidth control and VLAN division. In this way, consumers can experience the true "one investment and multiple gains ".

A port Image captures network packets and sends them to the specified port for output archiving. As to capture a port or all ports, capture uplink transmission data, downlink transmission data or two-way transmission data, in the TL-R480T products can be flexible settings. With the port image function, data transmitted over the network can be archived in a timely manner, and relevant department staff can master the network behavior of Internet users on the LAN. Nowadays, enterprises pay more and more attention to technical confidentiality and Information Security. The network facilitates information exchange, but it also provides channels for file leaks and virus attacks. Port Mirroring can be used to monitor inbound and outbound network data streams, providing security for enterprise networks. Internet cafes in many regions in China must have the network monitoring function so that the public security system can grasp the browsing status of Internet cafes in a timely manner. Many Internet cafes still use the old-fashioned HUB to capture packets, however, it is clear that the existence of the HUB directly affects the overall performance of Internet cafes. If you use a vro with the port image function, it can be easily managed in one step.

Bandwidth control can limit the port bandwidth to limit the data traffic on the port. If the bandwidth of a port is set to 100 kb, even if the port and the connected devices support 1000 Mbit/s or even 100 Mbit/s, the maximum data rate flowing through the port can only be kb. The advantage of "Broadband" over "narrow band" is that the band is wider, but even "Broadband" bandwidth is limited. In enterprises, many terminals share the inbound bandwidth, and resource competition is inevitable between them. In this case, using the bandwidth control function of TL-R480T products, you can set different bandwidth levels, to ensure the advantages of senior leadership resources, to minimize network congestion. For Internet cafes, the bandwidth control function makes it possible to distinguish Internet cafes quickly. Therefore, the profit model is not simple.

VLANVirtual Local Area Network (VLANVirtual Local Area Network) is a virtual working group that logically divides devices in the LAN, rather than physically dividing them into Network segments. After VLAN division, the broadcast and unicast traffic within a VLAN is not forwarded to other VLANs, which helps to control network traffic and improve network security. The Broadband Router is at the core of the enterprise network and basically has a small port switch. If the vswitch does not support VLAN functions and requires VLAN isolation for the network, the enterprise can only use one LAN port of the vro and add a VLAN-based switch, at this time, the small port switch integrated with the Broadband Router has only one port to be used. The customer bought a ticket for the built-in switch, but many port numbers are not available there, which is a waste of resources. The use of TL-R480T, that is, the routing function, and achieve the VLAN division of the switch, that is, the cost is reduced, and the management is simplified, enterprises and Internet cafes have been effectively affordable.

In general, an excellent Broadband Router requires not only powerful CPU, enough memory, high-quality hardware equipment, but also efficient and practical software functions! Whether the router functions are adequate and applicable is not only directly related to the investment costs of enterprises and Internet cafes, but more importantly, whether the entire network can run smoothly and concisely. What an excellent Broadband Router brings to end users should not be "flashy" or "strong in the field", but it must be "over success" or "icing on the cake "!
