dmt bitrate

dmt bitrate

To set the maximum and minimum allowed bit rates for the fast or interleaved DMT profile parameters, use the dmt bitrate profile configuration command. To reset this command to the default value, use the no form of this command.

dmt bitrate maximum {fast interleaved} downstream dmt-bitrateupstream dmt-bitratedmt bitrate minimum {fast interleaved} downstream dmt-bitrateupstream dmt-bitrate

Syntax Description

 

dmt-bitrate

The DMT bit rate is given as a multiple of 32 kbps. If you enter a

 

 

 

nonmultiple of 32 kbps, the system rejects and aborts the command. See the

 

 

 

allowed ranges and default values in Usage Guidelines.

 

 

 

 

 

 

fast

Specify the DMT fast latency path.

 

 

 

 

 

 

interleaved

Specify the DMT interleaved latency path.

 

 

 

 

 

The default no dmt bitrate maximum interleaved sets the maximum downstream and upstream

Defaults

 

 

 

interleaved bit rate to 640 and 128 kbps respectively. This command causes the port to retrain.

The default no dmt bitrate maximum fast sets both the maximum downstream and upstream fastpath bit rates to zero. This command causes the port to retrain.

The default no dmt bitrate minimum interleaved sets both the minimum downstream and upstream interleaved bit rates to zero. This command does not cause the port to retrain.

The default no dmt bitrate minimum fast sets both the minimum downstream and upstream fastpath bit rates to zero. This command does not cause the port to retrain.

Modification

12.0(5)DA

This command was introduced in a previous release.

 

 

12.1(5)DA

The fast keyword was added.

 

 

Usage Guidelines Only the alarm subsystem uses the minimum bit rate settings. Cisco IOS asserts an alarm if the line card trains at a rate below the configured minimum bit rate. However, no alarm occurs when you disable alarms. See alarms in the Command Reference for Cisco DSLAMS with NI-2, for more information on enabling and disabling alarms.

If alarms are enabled for the profile, setting the DMT bit rate to 0 disables the associated minimum DMT bit rate alarm.

Table 2 lists the allowable DMT bit rate ranges and default values.

8xDMT specifications

Cisco Systems’ 8xDMT, or "Eightfold Digital Multicast Technology," is a pioneering solution designed to optimize multicast traffic management and enhance the scalability of network performance. This technology comes into play primarily in video broadcasting, online gaming, and other applications that require the efficient distribution of data to multiple endpoints, significantly reducing the bandwidth use while improving overall network efficiency.

One of the primary features of Cisco 8xDMT is its ability to support multiple multicast streams concurrently. By using advanced algorithms, 8xDMT ensures that network resources are utilized efficiently, minimizing latency and maximizing throughput. This makes it particularly advantageous for service providers and organizations that deliver high-definition video content or require real-time data transmission across geographic locations.

Another notable characteristic of the Cisco 8xDMT is its integrated Quality of Service (QoS) capabilities. This feature allows for the prioritization of multicast traffic, ensuring that critical data packets are transmitted smoothly without delay, even during peak load times. The QoS management allows administrators to configure settings that guarantee minimal disruptions, providing end users with a seamless viewing or gameplay experience.

Additionally, Cisco 8xDMT takes advantage of Multicast Domain Name System (mDNS), which allows devices on the same network to discover and communicate efficiently. This not only aids in reducing the network load but also simplifies the management of multicast addresses, making it easier for organizations to scale their operations without significant overhead.

The technology also incorporates robust security features, including support for secure multicast transmissions. This ensures that sensitive data remains protected during distribution, addressing the increasing need for security in an era where cyber threats are prevalent.

Furthermore, Cisco Systems emphasizes interoperability with its 8xDMT platform, ensuring easy integration with existing network infrastructure. This is crucial for enterprises looking to modernize their systems without the need for extensive reinvestment in new hardware.

In conclusion, Cisco Systems’ 8xDMT stands out as a versatile and high-performance multicast solution designed to meet modern networking demands. With its ability to manage multiple streams, enforce QoS, simplify multicast management, and secure communications, it holds significant potential for transforming how organizations distribute data efficiently and effectively.
