Switch Flow Control

Introduction to Switch Port Flow Control

Switch port flow control is a critical feature for managing network congestion and ensuring smooth data transmission across the network. This article provides a comprehensive overview of switch port flow control, its benefits, and how to enable it on Zyxel switches.

Understanding Packet Buffers

Every switch has a hardware buffer, also known as a packet buffer. This buffer temporarily stores traffic during congestion to prevent packet loss. The size of the packet buffer varies by switch model. For example, the XGS 2220 has a packet buffer size of 2 megabytes.

Causes of Congestion

Network congestion can occur due to two main reasons:

  • High to Low Link Transmission: When a device connected to a high-speed (e.g., 10 Gbps) link sends data to a device on a lower-speed (e.g., 1 Gbps) link, the higher volume of traffic cannot be processed at the same rate by the lower-speed link, causing congestion.
  • Multiple Links to a Single Link: When multiple high-speed links send data to a single lower-speed link, the combined traffic can exceed the capacity of the single link, leading to congestion.

Ethernet Flow Control (IEEE 802.3X)

Ethernet flow control allows switches to send and process pause frames to manage traffic and prevent packet loss. When the packet buffer reaches a certain threshold, the switch sends a pause frame to the sending device to temporarily halt data transmission.

Key Concepts:

  • Pause Frame Threshold: The buffer level at which the switch triggers the transmission of pause frames.
  • TX Pause Frames: Sent by the switch to ports with flow control enabled to stop data transmission when the buffer reaches the threshold.
  • RX Pause Frames: Received by the switch from other devices, causing it to temporarily stop data transmission on the ports with flow control enabled.

Benefits of Flow Control

The primary benefit of flow control is to prevent packet loss during periods of congestion. While it introduces a small amount of latency, this is generally preferable to the higher latency and retransmission overhead caused by packet loss.

Enabling Flow Control

To enable flow control on a Zyxel switch:

  1. Access the Switch Port Settings: Navigate to the switch’s configuration page and select the port you want to configure.
  2. Enable Flow Control: Toggle the flow control option to enable sending and receiving pause frames.
  3. Filter by Flow Control Setting: Use the filter option to view and manage the flow control settings of each port.

Best Practices for Flow Control

While flow control can prevent packet loss, it should not be enabled on all ports indiscriminately. Consider the following best practices:

  • Target Specific Ports: Enable flow control on ports connected to servers or critical devices where congestion is likely to occur.
  • Avoid Enabling on Core Links: Do not enable flow control on links that are central to your network’s operation, as this can introduce latency that affects multiple devices.

Conclusion

Flow control is a valuable tool for managing network congestion and ensuring efficient data transmission. By understanding how it works and implementing it strategically, you can improve the performance and reliability of your network.

Strengthening Email Ecosystem: Outlook’s New Requirements for High‐Volume Senders

Quelle: Link

This applies to Outlook.com – our consumer service, which is supporting hotmail.com live.com and outlook.com consumer domain addresses.

Introduction

In an era where email remains one of the most widely used tools for personal and business communications, Outlook is stepping up its commitment to protect inboxes and preserve trust in the digital ecosystem. Today, we’re announcing new requirements and best practices designed to strengthen email authentication for domains sending more than 5,000 emails per day. 

These new requirements will enforce stricter standards by including mandatory SPF, DKIM, DMARC settings. Outlook is pushing the broader industry toward best practices and safeguarding the millions of individuals and small businesses that rely on us every day. These measures will help reduce spoofing, phishing, and spam activity, empowering legitimate senders with stronger brand protection and better deliverability. 

Outlook has always prioritized user safety and reliability; we’re proud to further invest in this solution that will keep our customers safe and reinforce the best practices across the industry. We believe that by raising the bar for large senders, we can inspire lasting change that benefits everyone. 

What’s Changing?

For domains sending over 5,000 emails per day, Outlook will soon require compliance with SPF, DKIM, DMARC. Non‐compliant messages will first be routed to Junk. If issues remain unresolved, they may eventually be rejected. Senders will soon start requiring compliance with the following requirements: 

  1. SPF (Sender Policy Framework)
    • Must Pass for the sending domain.
    • Your domain’s DNS record should accurately list authorized IP addresses/hosts.
  2. DKIM (DomainKeys Identified Mail)
    • Must Pass to validate email integrity and authenticity.
  3. DMARC (Domain-based Message Authentication, Reporting, and Conformance)
    • At least p=none and align with either SPF or DKIM (preferably both).

Learn more about email authentication here.

Additional Email Hygiene Recommendations

Large senders should also adopt these practices to maintain quality and trust:

  • Compliant P2 (Primary) Sender Addresses: Ensure the “From” or “Reply‐To” address is valid, reflects the true sending domain, and can receive replies. 
  • Functional Unsubscribe Links: Provide an easy, clearly visible way for recipients to opt out of further messages, particularly for marketing or bulk mail. 
  • List Hygiene & Bounce Management: Remove invalid addresses regularly to reduce spam complaints, bounces, and wasted messages. 
  • Transparent Mailing Practices: Use accurate subject lines, avoid deceptive headers, and ensure your recipients have consented to receive your messages. 

Outlook reserves the right to take negative action, including filtering or blocking—against non‐compliant senders, especially for critical breaches of authentication or hygiene. 

Enforcement Timeline

Starting today, we encourage all senders and particularly those that send at high volume to review and update their SPF, DKIM, and DMARC records, in preparation for when the enforcement begins, starting in May. 

After May 5th, 2025, Outlook will begin routing messages from high volume non‐compliant domains to the Junk folder, giving senders an opportunity to address any outstanding issues. NOTE: that in the future (date to be announced), non-compliant messages will be rejected to further protect users.   

Next Steps
  • Prepare Now: Audit your DNS records (SPF, DKIM, DMARC) and verify you meet all the requirements. To view the authentication header, visit this. To learn how to read authentication headers, click here. 
  • Stay Informed: We’ll provide updates on official rollout schedules, and dates for when rejection actions will begin through a blog post. 
  • Join Our Mission: Embracing better authentication and hygiene not only benefits your deliverability but also helps protect the entire email ecosystem.

Applies To
Wenn Sie kürzlich ein neues Windows-Gerät gekauft haben, können Sie das klassische Outlook möglicherweise nicht finden, oder das Symbol wird angezeigt, aber Sie erhalten eine Fehlermeldung, wenn Sie versuchen, es zu öffnen. Die Fehlermeldung besagt möglicherweise, dass Outlook nicht gefunden werden kann, oder sie könnte Folgendes sagen:

  • Wir konnten dies nicht überprüfen und installieren, da sie im Microsoft Store nicht verfügbar ist. Um es zu installieren, laden Sie sie von der Website des Publishers herunter.

Dieses Problem liegt daran, dass ab 2024 bei vielen neuen Geräten das neue Outlook für Windows vorinstalliert ist und das klassische Outlook nicht mehr mitgeliefert wird. Wenn Sie zu diesem Zeitpunkt lieber das klassische Outlook verwenden möchten, steht Ihnen eine eigenständige Version des klassischen Outlook für Windows zur Installation zur Verfügung.

Installieren des klassischen Outlook für Windows

Um eine eigenständige Version des klassischen Outlook für Windows zu installieren, wählen Sie Herunterladen aus und befolgen Sie die Anweisungen, um die Installation abzuschließen.

Herunterladen

Sie können es aus dem Windows Store installieren.
