Problems solved by technology

Also, as new devices connect to the network, bandwidth increases, so the probability of a faulty device flooding the network with junk traffic increases
Traditional connectivity networks do not differentiate between packets passed by or addressed to different applications and, therefore, are incapable of dealing with these issues

Embodiment Construction

[0035] Please refer to FIG. 1A, which shows a high-level functional block diagram of a prior art electronic communication network 100a. The network 100a includes a connection plane 110a and an application plane 130 . The connection plane 110a and the application plane 130 may be of various types known to those skilled in the art. For example, connectivity plane 110a may include conventional routers 112 and switches 114 (eg, layer 2 and / or layer 3 switches). For example, application plane 130 may include web, email, and voice applications.

[0036] More specifically, in the example shown in FIG. 1A , the application plane 130 includes two clients 132a and 132b and two servers 134a and 134b. Client 132a is an email client that processes email data 136a, and client 132b is a voice application that processes voice data 136b. Similarly, server 134a is an email server that serves email data 138a, and server 134b is a voice server that serves voice data 138b.

Abstract

The invention relates to Bi-planar network architecture. An electronic communication network adopting Bi-planar network architecture includes a connectivity plane and a control plane. The control plane includes at least one control node for inspecting packets received by the control plane. The control plane is configured to perform network traffic control functions on the packets received by the at least one control node before transmitting the packets to any other node in the network. The network traffic control functions include one or more of access control, attack control, and application control.

Description

technical field [0001] The present invention relates to an electronic communication network, and in particular to a technique for performing access control, attack control and application control in a packet switching network. Background technique [0002] Electronic communication networks based on Internet Protocol (IP) have become ubiquitous. The main focus of the information technology (IT) industry in the last two decades has shifted to "anytime, anywhere" IP network connectivity, and this problem has been largely solved. Individuals can now communicate with each other using a variety of devices connected to a combination of public and private networks, and use applications within and between private businesses, government agencies, public spaces such as coffee shops and airports, and even private residences. Corporate managers can now use a handheld device in a restaurant to reliably and wirelessly send e-mail messages to a teacher using a desktop computer connected to...
