Release

In this release, the throughput gain has been increased. KPIs - separate counters for IP versions (IPv4/IPv6) and application protocols (HTTP/HTTPs), are added.

21.10

In this release, two new commands - accl-flags and cwnd-gain , are added to the TCP Acceleration Profile Parameters configuration. Configuring these commands increases throughput gain and optimized mid-flow proxy engagement procedures for TCP accelerated flows.

Also, the output for the show tcp-acceleration-profile command has been updated.

21.9.1

Inline TCP Optimization engine is enhanced to dynamically engage the TCP acceleration module at mid-flow.

21.9

First introduced.

21.8

Feature Description

Inline TCP Optimization is an integrated solution to service providers to increase the TCP flow throughput for TCP connections. This solution enables faster transmission of data for a better user experience.

The Inline TCP Optimization solution ensures accelerated TCP flows using a proprietary algorithm that provides efficient and optimal throughput at a given time. A TCP proxy has been integrated with this solution to monitor and control the TCP congestion window for optimal throughput.

The Inline TCP Optimization solution also supports split TCP sessions to accommodate wireless requirements and provides feature parity with other existing inline services.


Note

Optimization only applies to the downlink data on the Gn interface.


The Inline TCP Optimization feature is license controlled. Contact your Cisco account representative for detailed information on specific licensing requirements. For information on installing and verifying licenses, refer to the Managing License Keys section of the Software Management Operations chapter in the System Administration Guide.

How It Works

The TCP Optimization feature includes the following functionalities:

  • TCP Connection Splicing: The TCP connections are split into two connections; one connection towards Gn and the other connection towards Gi, inside P-GW. The connections are split in a transparent manner in the P-GW so that the UE and the Gi servers are transparent to the connection being split.

  • TCP Proxy ensures seamless movement of data across these two TCP split connections.

  • TCP Optimization is deployed on the Gn interface (towards the UE) of the TCP stack. A user-space TCP stack in P-GW is used.

  • Cisco library for TCP optimization:

    • Provides algorithms that are designed to increase the TCP throughput.

    • Interfaces with the User-space TCP stack (Gn interface) and notifies appropriate events that occur in the TCP connection and takes actions accordingly.

    • Provides APIs to integrate the Cisco Library (for TCP optimization) and StarOS.


Note

TCP Acceleration is enabled during the start of the TCP flow (when SYN packet is received). It cannot be disabled later during the flow.


Accelerating Selected TCP Flows

The Inline TCP Optimization solution is designed to optimize most-eligible TCP flows.

The following are a few criteria to select TCP flows for acceleration:

  • Based on the amount of data seen on the flow: Flows that have data more than that of the threshold value are accelerated.

  • TCP acceleration is avoided in certain scenarios for throttled TCP flows. For example:

    • ADC flows that configured to be throttled.

    • TCP flows throttled due to breaching data limit triggered by OCS/PCRF.

    • Tethered flows that are throttled.

  • Based on GBR/non-GBR: Only TCP flows on default bearers is applicable for TCP acceleration.


Note

TCP acceleration is only supported for LTE RAT-Type.


Configuring Inline TCP Optimization

Enabling TCP Acceleration under Active Charging Service

Use the following configuration to enable TCP acceleration:

      end  

NOTES:

  • tcp-acceleration : Enables TCP acceleration under the ACS Configuration mode.

Enabling TCP Acceleration under Trigger Action

Use the following configuration to enable TCP acceleration:

configure  
   require active-charging  
   active-charging service  service_name 
      trigger-action  trigger_action_name 
         tcp-acceleration profile  profile_name 
         end  

NOTES:

  • tcp-acceleration : Enables TCP acceleration under the ACS Trigger Action Configuration mode.

  • profile : Identifies the TCP acceleration profile. The profile_name is a string ranging from 1 to 63 characters.

Configuring a TCP Acceleration Profile

Use the following configuration to configure a TCP Acceleration Profile:

configure  
   require active-charging

      [ no ] tcp-acceleration-profile  profile_name 
      end  

NOTES:

  • no : Disables the TCP Acceleration profile.

Configuring TCP Acceleration Profile Parameters

Use the following commands to configure the TCP acceleration profile parameters:

configure  
   require active-charging  
   active-charging service  service_name 
      [ no ] tcp-acceleration-profile  profile_name 
         accl-flags  flag_value

         cwnd-gain { dynamic { off | on } [ factor  factor_value ] | factor  factor_value [ dynamic { off | on } ] }  
         default cwnd-gain  
         default buffer-size [ downlink | uplink ]  
         initial-cwnd-size  window_size 
         default initial-cwnd-size  
         max-rtt  max_rtt_value 
         default max-rtt  
         mss  mss_value 
         default mss  
         end  

NOTES:

  • accl-flags : Configures TCP acceleration related optimization flags. The flag_value is an integer ranging from 0 to 65535.

  • buffer-size : Configures the TCP Proxy buffer size for downlink and uplink data in Kilobytes.


    Note

    This command is supported from 21.9.1 and later releases


  • cwnd-gain : Configures the TCP congestion window gain. This command is used by the TCP optimization engine to continuously calculate the actual congestion window size. Scaling the window size allows the TCP optimization engine to manage the in-flight of data in the engine.

    • The dynamic option in this command automatically scales-up the congestion window gain to ensure that it is sized correctly to allow for RTT variation during the flow.

    • The factor option configures the TCP congestion window gain factor. The factor_value is an integer ranging from 1 to 16378.


    Note

    This command is supported from 21.9.1 and later releases


  • initial-cwnd-size : Configures the initial congestion window size in segments. The window_size is an integer ranging from 1 to 65535.

  • max-rtt : Configures the maximum RTT value in milliseconds. The max_rtt_value is an integer ranging from 1 to 10000.

  • mss : Configures the maximum segment size for TCP in Bytes. The mss_value is an integer ranging from 496 to 65535.

Configuring Post-Processing Rule Name under Trigger Condition

Use the following commands to configure the post-processing rule names:

configure  
   require active-charging  
   active-charging service  service_name 
      trigger-condition  trigger_condition_name 
         post-processing-rule-name { = | contains | ends-with | starts-with }  rule_name 
         [ no ] post-processing-rule-name  rule_name 
         end

   require active-charging  
   active-charging service  service_name 
      edr-format  edr_format_name 
         rule-variable tcp [ sn-tcp-accl | sn-tcp-accl-reject-reason | sn-tcp-min-rtt | sn-tcp-rtt ] priority  priority_value

Configuring Flow Length Threshold for a TCP Flow under Trigger Action

The flow length threshold of a TCP flow is configured using Trigger Action under the service-scheme framework. The threshold value of the flow length is used to engage the TCP Acceleration module dynamically.

Use the following configuration to engage TCP acceleration module during mid-flow:

configure  
   require active-charging  
   active-charging service  service_name 
      trigger-action  trigger_action_name 
         tcp-acceleration flow-length threshold  threshold_value

NOTES:

  • no : Disables flow recovery for a trigger-action.

  • flow-length : Specifies the flow length action for a TCP flow.

  • threshold : Specifies the threshold value of the flow length in bytes, for a TCP flow. The threshold value is an integer ranging from 1 to 10000 bytes.

The flow length condition exceed for a TCP flow is configured using Trigger Condition under the service-scheme framework.

Use the following configuration to configure a condition for a TCP flow length:

configure  
   require active-charging  
   active-charging service  service_name 
      trigger-condition  trigger_condition_name 
         flow-length threshold exceed  
         end
