The availability of a TCP/IP network design focuses on the percentage of time users are able to transfer data by using the TCP/IP network infrastructure.. Discussion: Evaluating TCP/IP Availability and Performance Requirements. The performance of a TCP/IP network is set at a base level by the underlying physical network topology. You can enhance the TCP/IP performance for particular applications by:.

All devices in the network remain part of the same MAC broadcast domain, however. The parallel backbone topology is a modification of the collapsed backbone. In the case of the IP protocol, this new domain is the IP network domain.. In this example, every device in the LAN has its own IP address, and they are all part of the network.. In the case of the LAN's gateway router, the MAC address corresponds to the router interface port's MAC address.

Name the five different classes of IP addresses. Describe the characteristics and use of the different IP address classes. Identify the class of an IP address based on the network number. Determine which part, or octet, of an IP address is the network ID and which part is the host ID. Identify valid and invalid IP host addresses based on the rules of IP addressing. This lab exercise helps develop an understanding of IP addresses and how TCP/IP networks operate.

In many instances, the type of port is dependent on the voice device connected to the network. IP phones that connect to the network via switches place on-net calls through Cisco Unified Communications Manager. The call is sent from the local voice-enabled router that is acting as a gateway to the PSTN. The call is then sent to the PSTN for call termination.. The call is automatically dialed based on the PLAR configuration of the voice port. This includes IP phones connected to the IP network.

Depending on how you have configured your network interfaces, you might need to configure additional VoIP dial-peer parameters. For example, to ensure that voice traffic associated with VoIP dial peer 103 is given a higher priority than other IP network traffic, enter the following:. dial-peer voice 103 voip ip precedence 5.

An H.323 gateway is an endpoint on the network which provides for real-time, two-way communications between H.323 terminals on the IP network and other ITU terminals on a switched based network, or to another H.323 gateway. It is the most vital component of the H.323 system and dispatches the duties of a "manager". Some of the functionalities that gatekeepers provide are listed below.

If two or more voice gateways or CallManager Express routers need to send signaling to each other over an IP network, the router configuration commands called dial peers are configured, also based on H.323. The solution to simplify management and troubleshooting is another optional H.323 component called a gate- keeper. Centralized call routing allows for all of the Gateways, CMEs, or CCMs to be configured with a single dial peer or ICT pointer to the gatekeeper.
