Layer 2

The Egress Layer 2 page allows you to map the CoS of an outgoing packet to user priority bits, which is honored by the VLAN network. Again, this feature is only configurable on the WAN interfaces as VLAN is only supported on the WAN side in the current release.

Layer 2

Field

Description

 

 

Interface

Select the WAN interface to configure the QoS for outgoing packets; LAN interface cannot be

 

selected as VLAN is currently supported on the WAN side only.

 

 

Unclassified

Some locally generated packets might not have been classified and thus do not have a CoS value,

Packet

such as PPP control packet and ARP packet. You can define the CoS for all unclassified outgoing

 

packets on layer 2 using this field, which will then pick up the user priority bits based on the

 

mapping rules you create. The selections are (in the order of descending priority): CoS1, CoS2,

 

CoS3, CoS4, CoS5, and CoS6. The default value is CoS1 (recommended).

 

 

Class of Service

The selections are (in the order of descending priority): CoS1, CoS2, CoS3, CoS4, CoS5, and

 

CoS6.

 

 

User Priority

The selections are 0, 1, 2, 3, 4, 5, 6, and 7.

Shiro ADSL 2/2 user manual Layer Field Description

ADSL 2/2 specifications

Shiro ADSL 2/2 is a high-performance broadband connectivity solution designed to deliver reliable and fast internet access to residential and business users. As an asynchronous digital subscriber line (ADSL) technology, it offers significant improvements over standard ADSL, making it a preferred choice for users who seek enhanced performance and efficiency in their online activities.

One of the main features of Shiro ADSL 2/2 is its ability to provide increased download and upload speeds. With a maximum download speed of up to 24 Mbps and an upload speed reaching up to 3.5 Mbps, users can enjoy a seamless internet experience suitable for streaming, gaming, video conferencing, and other bandwidth-intensive applications. These speeds are achieved through the use of advanced modulation techniques that optimize the use of available bandwidth over telephone lines.

Another key characteristic of Shiro ADSL 2/2 is its backward compatibility with existing ADSL technologies. This means that users can upgrade to Shiro ADSL 2/2 without the need for extensive infrastructure changes. It can efficiently operate over the same copper lines already in use, allowing for a cost-effective upgrade path for many households and businesses.

The technology behind Shiro ADSL 2/2 is based on high-frequency signaling, which makes it possible to transmit data more efficiently. This technique reduces crosstalk and interference, resulting in more stable connections. Additionally, Shiro ADSL 2/2 incorporates error correction mechanisms that further enhance data integrity and performance.

Another noteworthy feature is its support for Multiple Input Multiple Output (MIMO) technology. This allows multiple data streams to be transmitted and received simultaneously, improving overall throughput and signal quality. Users benefit from increased network reliability, especially in environments where signal quality may be less than ideal.

Shiro ADSL 2/2 also emphasizes security, providing robust encryption protocols to protect user data from unauthorized access. This ensures that personal and sensitive information transmitted over the internet remains safe.

In summary, Shiro ADSL 2/2 stands out as a powerful solution in the realm of broadband internet access. With its impressive speed capabilities, backward compatibility, advanced signaling techniques, support for innovative technologies like MIMO, and a focus on security, it delivers a robust and satisfying online experience for all users. Whether used for casual browsing or demanding applications, Shiro ADSL 2/2 continues to meet the evolving needs of the digital age.
