Traffic Control
 bliet.jpg packetLiner Traffic Control Solution

To respond to the growth and innovation in data networks, recently CSPs have begun to explore traffic control solutions as a way to improve customer experience, drive new revenue stream, and use their networks more efficiently. As the CSPs and enterprise network infrastructure expands to support different types of traffic and users, advanced traffic control solutions become critical. For the fulfillment of CSPs needs, complete visibility into network's behavior also becomes more important and more challenging. However traffic control problems including application performance, bandwidth utilization, network congestion and appropriate prioritization of user and application traffic are questions that often go unanswered. Most traffic control solutions available in the market have serious limitations: difficult to understand how service or user or application levels can be assured, too expensive, and unable to scale with high speed networks.
packetLiner traffic control solution addresses the various site-specific or environmental traffic control requirements of today's CSPs and enterprise networks and overcomes the limitations of other solutions.


[ Policy Enforcement & Traffic Control ]

packetLiner delivers subscriber, service, and application-aware traffic control solution that enables network administrator to intelligently steer their data traffic, conserve network resources, and quickly deliver profitable new services, which enable companies to effectively administer networks of all shapes and sizes.
In addition, they allow network administrators to make smart decisions about network access, traffic prioritization, traffic flows, and bandwidth optimization from one central management console and then easily propagate these decisions out to the edge of the network for policy enforcement. As a result, network administrators with the help of packetLiner traffic control solution can be assured to have simple, affordable tools that can quickly answer the following questions:

 • Is network performance slowing down or becoming congested?
 • Is it possible to identify P2P heavy-hitters, effectively clogging the network?
 • What is the current network usage, and what has it been in the past hour?
 • Which network routers are most active or over-utilized?
 • Why is a server slow or inaccessible?
 • Which users and applications are driving network traffic?
 • Which users and applications are starving for bandwidth?
 • How much bandwidth do I need for new applications?

packetLiner traffic control combines with the subscriber and service, and application awareness to be performed at the pre stage of traffic classification. The execution of control refers to the registered policies, which can be based on Black List(BL), Access Control List(ACL), control policy, subscriber group policy. The controlled objects can be ACL entries, Service, Service Group, Service Provider, Devices, Application Protocol, Host, Domain and combined with the specific traffic control treatment, e.g., Deny Packet, Rate Limit, HTTP Redirect, Packet Divert, and TCP Reset. Traffic classification functionality analyzes the traffic flow and matches the specific object that will receive traffic control treatment, and then control that traffic flow according to the registered policy.
packetLiner products offer the traffic control capabilities such as URL filtering, blocking or logging the traffic to exceed the session threshold, time-scheduled control, rate/burst/session/log limited bandwidth control, mirroring, forwarding, priority control, or http redirection for steering.

Looking at mobile traffic composition, while video takes up a small portion of the traffic flows, it can take up to 65 percent of the bandwidth. Optimizing video traffic alone can have a very large impact on overall bandwidth usage on the edge of the network. Video traffic can be greatly optimized, and there are several vendors that are very proficient in reducing the bandwidth usage of a video stream. To address the typical mobile network problem like these, packetLiner traffic control solution can redirect traffic based on the service carrying the specific content type. packetLiner redirects video streaming service-related traffic to a video optimizer, for example. This results in very efficient use of the video optimizer solution, and packetLiner is able to balance the traffic over multiple appliances, resulting in a highly scalable, high availability solution. Moreover, the decision for redirecting traffic is not made solely upon the service type; such a decision could, optionally, be made using a more flexible array of policy variables. For example, it can determine what type of smartphone is connecting, and steer its traffic to a specific optimization device for that smartphone's video resolution.
