Chapter XIV. UDP Segmentation Offload and Pacing 

Chelsio T5/T4 Unified Wire for Linux

 

Page 199

 

1. Introduction 

Chelsio’s  T5/T4  series  of  adapters  provide  UDP  segmentation  offload  and  per-stream  rate 
shaping  to  drastically  lower  server  CPU  utilization,  increase  content  delivery  capacity,  and 
improve service quality. 

Tailored for UDP content, UDP Segmentation Offload (USO) technology moves the processing 
required to packetize  UDP  data and rate control its transmission from software running on the 
host  to  the  network  adapter.    USO  increases  performance  and  dramatically  reduces  CPU 
overhead, allowing significantly higher capacity using the same server hardware. Without  USO 
support,  UDP  server  software  running  on  the  host  needs  to  packetize  payload  into  frames, 
process  each  frame  individually  through  the  network  stack  and  schedule  individual  frame 
transmission,  resulting  in  millions  of  system  calls,  and  packet  traversals  through  all  protocol 
layers in the operating system to the network device. In contrast, USO implements the network 
protocol stack in the adapter, and the host server software simply hands off unprocessed UDP 
payload in large I/O buffers to the adapter. 

The  following  figure  compares  the  traditional  datapath  on  the  left  to  the  USO  datapath  on  the 
right, showing how per-frame processing is eliminated. In this example, the video server pushes 
5  frames  at  a  time.  In  an  actual  implementation,  a  video  server  pushes  50  frames  or  more  in 
each I/O, drastically lowering the CPU cycles required to deliver the content. 

 

Pacing  is  beneficial  for  several  reasons,  one  example  is  for  Content  Delivery  Networks 
(CDNs)/Video  On  Demand  (VOD)  providers  to  avoid  receive  buffer  overflows,  smooth  out 
network 

traffic, 

or 

to 

enforce 

Service 

Level 

Agreements 

(SLAs).
