Wan Acceleration Solution

The application accelerator can provide the most effective application Acceleration Solution for all users, such as fixed network, wireless, narrowband, broadband, public network, and private network. The Wan acceleration product can quickly transmit application data on the network, which is extremely effective for link transmission with long distance, long latency, and high packet loss rate. It enables faster transmission of network applications, users do not need to wait for network response for a long time, and the customer's use of network bandwidth resources is also greatly increased. It can fully tap the potential of bandwidth, allow limited WAN links to accommodate more data streams, and also allow long-distance and high-latency links to handle more traffic, bring the potential of these links to the extreme.
TCP acceleration or TCP optimization can help improve the performance of TCP-based applications in the network environment, such as large bandwidth links, large file transmission, high latency, and considerable network transactions. TCP optimization mainly solves the problem of data packet loss and TCP latency. Latency is inherent in the Wide Area Network. Even if the propagation delay is short, there is still a long serial delay on the low-speed link, which is more serious on the satellite link. Latency can be solved through the acceleration technology, the most basic of which is TCP acceleration. This technology believes that the slow response time caused by delay is mostly the result of TCP waiting for confirmation. The simplest solution is to intercept tcp ack messages and manage information transmission over the wide area network. In this way, the host determines that the remote end is located side by side with it on the LAN, so that it can interact with the acceleration platform at a faster speed.
The application accelerator uses the unique TCP optimization technology to accelerate various SSL, IPSec, L2TP, PPTP, and so on. Acceleration can be applied to all TCP/IP-based applications. In particular, it can achieve unilateral acceleration without pairing (both ends of the network). In addition, it can achieve bidirectional acceleration of VPN data, it also increases the upload and download speeds and makes full use of upstream/downstream bandwidth resources. VPN acceleration is more effective for long-distance, long-latency, and high packet loss rate link transmission.
High-speed transparent compression technology TFC
High-speed transparent & flowlined compression (TFC) is used to compress data at the network layer in real time. The data compression process is at the bottom of the network and is unrelated to the application, so that all applications can benefit from transparent stream compression. Compression and decompression do not change the data format, and ensure that the sent data packets are exactly the same as those sent by the sender. They can be verified by any network security level. No tunnel mechanism is required before compression and decompression, completely transparent to the network, so it will not bring security concerns to users, and the security devices in the network path will not consider the compressed data as illegal data and discard it. Automatic Discovery of network acceleration devices: automatic discovery of peer acceleration devices (if any) and automatic interception of communication information, enabling high-speed data compression and decompression. The compression ratio provided by the high-speed compression algorithm can reach 50: 1, 400: 1 or even: 1, which far exceeds other technologies in terms of bandwidth savings. High-speed transparent compression after TFC can improve network performance by 200%-5000% (2 to 50 times), saving network bandwidth by 50% to 98%.
When there is a large amount of upstream traffic in the network or the uplink bandwidth is full, the downlink speed of the network decreases sharply, that is, the usage of the downlink bandwidth decreases sharply, this is an issue that cannot be solved currently. The main reason is that when the upstream traffic is large, the ACK packet transmission channel of the downstream TCP traffic is greatly affected, and the ACK packet transmission of the downstream traffic is slow or even unable to be transmitted, as a result, the downstream bandwidth cannot be effectively utilized and the downstream traffic transmission speed slows down.
You can automatically adjust network data streams and improve the network experience. Shaping traffic to reduce burst, ensuring stable transmission of network data, and avoiding network equipment congestion. More importantly, it can easily solve the common problem of "Uplink pressure down, that is, when the uplink bandwidth is used up, the downlink bandwidth usage decreases sharply. An actual test shows that when the application accelerator Traffic Shaping function is not enabled, the uplink speed is 500 kbps, And the downlink speed is only 800 kbps. When the application accelerator Traffic Shaping function is enabled, the uplink speed remains unchanged, the downlink speed reaches 3 Mbps, which is nearly 4 times higher.
Intelligent and automatic detection of the number of machines connected to the internal LAN; the entire network bandwidth is "fairly" allocated to these machines; when a machine accesses the Internet, this machine uses all network bandwidth; when 10 Internal machines access the Internet, 10 machines use the whole network bandwidth on average; when the bandwidth used by one machine is lower than the bandwidth allocated to it, the "saved" bandwidth can be "borrowed" from other machines (bandwidth borrow ); you can set limits on the number of TCP and UDP connections for internal hosts on the Internet.
