  • Static NAT – Mapping an unregistered IP address to a registered IP address on a one-to-one basis. Particularly useful when a device needs to be accessible from outside the network.Dynamic NAT – Maps an unregistered IP address to a registered IP address from a group of registered IP addresses. Dynamic NAT also establishes a one-to-one mapping between unregistered and registered IP address, but the mapping could vary depending on the registered address available in the pool, at the time of communication....

  • Modern WAN architectures require additional network capabilities to support current higher bandwidth and mission-critical applications. Requirements for deploying voice over IP (VoIP) and video conferencing include high availability, IP multicast, and quality of service (QoS). Today, most enterprises rely on private WAN connections such as Frame Relay, ATM, or leased-line services to connect their businesses.

  • Enterprise data centers contain the assets, applications, and data that are often targeted by electronic attacks. Endpoints such as data center servers are key objectives of malicious attacks and must be protected. The number of reported attacks, including those that affect data centers, continues to grow exponentially every year (CERT/CC Statistics 1988-2002, CSI/FBI 2001). Attacks against server farms can result in lost business for e-commerce and business-to-business applications, and the theft of confidential or proprietary information.

  • The Internet Protocol (IP) Multimedia Subsystem, better known as "The IMS", is based on the specification of the Session Initiation Protocol (SIP) as standardized by the Internet Engineering Task Force (IETF). But SIP as a Protocol is only one part of it; the IMS is more than just a protocol. It is an architecture for the convergence of data, speech and mobile networks and is based on a wide range of protocols, of which most have been developed by the IETF.

  • Packet snooping can be detected in certain instances, but it usually occurs without anyone knowing. For packet snooping to occur, a device must be inserted between the sending and receiving machines. This task is more difficult with point-to-point technologies such as serial line connections, but it can be fairly easy with shared media environments. If hubs or concentrators are used, it can be relatively easy to insert a new node. However, some devices are coming out with features that remember MAC addresses and can detect whether a new node is on the network.
