Best isdn networking books according to redditors

Yes, those are the two sections that I haven't done v4 recordings for yet. Multicast will be added in the near future as part of a larger multicast series I'm working on.

QoS hasn't changed from the SPv3 to SPv4 blueprints. Here they are side by side:

SPv3 Blueprint:

• 1.10. SP QoS
  
• 1.10.1. Marking using DSCP, IP precedence and CoS
  
• 1.10.2. Priority Queuing
  
• 1.10.3. Custom Queuing
  
• 1.10.4. Weighted Fair Queuing
  
• 1.10.5. WRED
  
• 1.10.6. Policing
  
• 1.10.7. Class-based Weighted Faire Queuing (CB-WFQ)
  
• 1.10.8. Low-Latency Queuing (LLQ)
  
• 1.10.9. Random-Detect using MQC
  
• 1.10.10. NBAR for QoS
  
• 1.10.11. MPLS EXP
  
• 1.10.12. Differentiated Services Traffic Engineering (DS-TE)
  
• 1.10.13. Maximum Allocation Model (MAM)
  
• 1.10.14. Russian Dolls Model (RDM)
  
• 1.10.15. Class-Based Tunnel Selection: CBTS
  
• 1.10.16. Policy-based Tunnel Selection: PBTS
  
  SPv4 Blueprint:
  
  
• 1.6 Quality of Service (QoS)
  
• 1.6.a Describe, implement, and troubleshoot classification and marking
  
• 1.6.b Describe, implement, and troubleshoot congestion management and scheduling, for example, policing, shaping, and queuing
  
• 1.6.c Describe, implement, and troubleshoot congestion avoidance
  
• 1.6.d Describe, implement, and troubleshoot MPLS QoS models (MAM, RDM, Pipe, Short Pipe, and Uniform)
  
• 1.6.e Describe, implement, and troubleshoot MPLS TE QoS (CBTS, PBTS, and DS-TE)
  
• 3.3 Quality of Service (QoS)
  
• 3.3.a Describe, implement, and troubleshoot classification and marking
  
• 3.3.b Describe, implement, and troubleshoot congestion management and scheduling, for example, policing, shaping, and queuing
  
• 3.3.c Describe, implement, and troubleshoot congestion avoidance
  
  
  Beyond those QoS videos in the playlist, I would recommend to read the following:
  
  
• Chapter 13. Implementing Quality of Service in MPLS Networks from MPLS Configuration on Cisco IOS Software
  
• Part VII: MPLS VPN QoS Design from End-to-End QoS Network Design
  
  Edit: Also, check out Packet Volume 7 No. 1, First Quarter 1995.. There's a great article on page 11 titled "Building Consistent Quality of Service into the Network". ;)
  
  

Intermediate: Javascript and Ajax

I highly recommend the book Head First Ajax by Rebecca Riordan. Ultimately, you may decide to use a framework like jQuery for simplifying the XMLHttpRequest API, but this book really helps explain AJAX, how it works, and how to write AJAX requests using vanilla JavaScript.

The Head First books are especially helpful for beginners, I really like the approach they take to teaching you in ways that are visual and make it easier to remember.
