  • Carrier Sense Multiple Access (CSMA) is a probabilisticMedia Access Control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium CAN uses a nondestructive bitwise arbitration, which means that messages remain intact after arbitration is completed even if collisions are detected. All the arbitration takes place without corruption or delay of the message that wins the arbitration.

  • Check Point IPS is an Intrusion Prevention System (IPS). Whereas the Security Gateway firewall lets you block traffic based on source, destination and port information, IPS adds another line of defense by analyzing traffic contents to check if it is a risk to your network. IPS protects both clients and servers, and lets you control the network usage of certain applications. The new, hybrid IPS detection engine provides multiple defense layers which allows it excellent detection and prevention capabilities of known threats, and in many cases future attacks as well.

  • After converting your network from hubs to switches you may find it difficult to use your protocol analyzer to observe traffic between devices. Since switches filter traffic based on the MAC address, you can no longer see traffic destined for a device on a particular port on any of the other ports. You need to setup a port on your Ethernet switch as a “Monitor” or “Span” port. Once you have designated a port on your switch as a monitor port, you can copy input and output traffic from another port to your monitor port....

  • Simple Network Management Protocol (SNMP) provides a "simple" set of operations that allows you to more easily monitor and manage network devices like routers, switches, servers, printers, and more. The information you can monitor with SNMP is wide-ranging--from standard items, like the amount of traffic flowing into an interface, to far more esoteric items, like the air temperature inside a router. In spite of its name, though, SNMP is not especially simple to learn.

  • Today’s transmission methods and equipment are robust and reliable and feature integrated network monitoring, troubleshooting, maintenance, and provisioning systems. However, public carriers and most major private networks have historically engineered their network’s physical plant to include access points at which they can gain quick and organized “hard-contact” access to any particular circuit path. Typically, these access points were comprised of analog jackfields with “line-drop-monitor” access capability.

  • The computer software is divisible into several modules in terms of function. Figure 47.14 shows the relationships of these modules. The monitor is a small program permanently stored in read-only memory (ROM) in the microcomputer. It performs basic traffic direction and boots up the supervisor. That is, when the computer is switched on, the monitor expects to find a program waiting to be read from a mass storage device. It initiates reading of this program, which is, in fact, the remainder of the permanent software. ...

  • Establish a clear network access control policy. It is often the case that the administrators of grid resources are not the same individuals as those of site access control systems (e.g. firewalls). Consequently, it is important for the reliability and availability of grid services that the connectivity requirements are properly communicated and agreed by the network managers. This will reduce the likelihood of ports being closed unexpectedly and facilitate the proper monitoring of traffic.

  • Historically, the Ontario Medical Association (OMA) has taken a strong stand advocating reductions in air pollution in Ontario as an essential means to improve public health. Beginning in 1967, the Ontario Medical Association Council endorsed a program of air pollution control in Ontario which included the establishment of monitoring stations and regulation of emissions from industry and vehicular traffic (15). Shortly thereafter, the government enacted the Air Pollution Control Act encompassing a number of the recommendations from the OMA.
