Release Overview These Release Notes cover Release 2. 0. 5 of the Juniper Networks Media Flow Controller system software. If the information in these Release Notes differs from the information found in the published documentation set, follow these Release Notes. Release 2. 0. 0 and Release 2. 0. 1 were released earlier for controlled usage such as evaluation, proof-of-concept, and so forth. Release 2. 0. 2 through Release 2. 0. 5 are the recommended releases for large-scale deployments. Please see the Media Flow Controller 2. 0. 4 Release Notes for additional information. Copyright © 2010, Juniper Networks, Inc. Release Overview 7 Release 2. 0. 5 Media Flow Controller 2. 0. 5 Release Notes New Features Release 2. 0. 5 introduces some changes and fixes for known issues from lower-numbered releases. This section describes new subcommands to these commands: · · · · Namespace Delivery Protocol HTTP Client-Request Network TCP Ram-Cache Virtual Player Hash Verify Namespace Delivery Protocol HTTP Client-Request · For namespace <n> delivery protocol http client-request there is a new option that you can use to ensure that all requests processed by that namespace are directly tunneled to the origin: tunnel-all Notes: · tunnel-all--Configure this namespace to tunnel all incoming requests to the origin server without further processing. The default value is disabled. Network TCP · For network tcp there is a new option useful when running non-persistent connections or performance tests on Transparent proxy configurations: max-tw-buckets <number> Notes: · max-tw-buckets--Define the maximum allowed number of TIME_WAIT sockets held by the system simultaneously. If this number is exceeded, TIME-WAIT sockets are immediately destroyed and a warning is displayed. The default value is 180000. Ram-Cache · For ram-cache there is a new option to help with handling small objects: small-buffers scale-factor <number> Notes: · small-buffers scale-factor--Configure the ratio between 32 KB buffers and 4 KB buffers in the RAM cache. The default, 0 (zero), translates to a ratio of 1:1. 25, which may not always be optimal. Acceptable values are between 0 and 8; if n = 1 - 8, the ratio is 1:2^n. 8 New Features Copyright © 2010, Juniper Networks, Inc. Media Flow Controller 2. 0. 5 Release Notes Release 2. 0. 5 Virtual Player Hash Verify · For generic and smoothflow type virtual-players, there are new hash-verify options to help prevent bandwidth stealing and to allow you to refine your hash calculation: expiry-time-verify query-string-parm <string> url-type {absolute-url | relative-uri | object-name} Notes: · expiry-time-verify query-string-parm--Specify a query parameter string for expiry-time-verify; for example, e. The value supplied by the query parameter must be a standard POSIX timestamp (seconds since January 1 1970 00:00:00 UTC). Media Flow Controller extracts the timestamp value from an incoming URL and compares it with the current time in its system to determine if the URL request has expired. An expiry time of 0 (zero) indicates it "does not expire. " Sample URL request form where "e" indicates the expiry-time-verify query-stringparm value: http://www. example. com/media/foo. flv?e=3312665958&h=ec41f550878f45d9724776761d6ac416 · url-type--Specify which part of the request URL to use to generate the hash for hash-verify: · absolute-url--Current and default behavior. [. . . ] Go to the System Config > Reboot page and click Reboot. · · If you have not made system configuration changes since your last reboot, a System Reboot or Shutdown page is displayed. If you have made system configuration changes since your last reboot, a Confirm Reboot page is displayed. If the System Reboot or Shutdown page is displayed, click Reboot or Shutdown. [. . . ]
