Please use with caution. + + +.. index:: + Delivery Service Type + +.. _rl-ds-types: + +Delivery Service Types +++++++++++++++++++++++ +One of the most important settings when creating the delivery service is the selection of the delivery service *type*. This type determines the routing method and the primary storage for the delivery service. + ++-----------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| Name | Description | ++=================+================================================================================================================================================================+ +| HTTP | HTTP Content Routing - The Traffic Router DNS auth server returns its own IP address on DNS queries, and the client gets redirected to a specific cache | +| | in the nearest cache group using HTTP 302. Use this for long sessions like HLS/HDS/Smooth live streaming, where a longer setup time is not a. | +| | problem. | ++-----------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| DNS | DNS Content Routing - The Traffic Router DNS auth server returns an edge cache IP address to the client right away. The client will find the cache quickly | +| | but the Traffic Router can not route to a cache that already has this content in the cache group. Use this for smaller objects like web page images / objects. | ++-----------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| HTTP_NO_CACHE | HTTP Content Routing, but the caches will not actually cache the content, they act as just proxies. The MID tier is bypassed. | ++-----------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| HTTP_LIVE | HTTP Content routing, but where for "standard" HTTP content routing the objects are stored on disk, for this delivery service type the objects are stored | +| | on the RAM disks. Use this for linear TV. The MID tier is bypassed for this type. | ++-----------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| HTTP_LIVE_NATNL | HTTP Content routing, same as HTTP_LIVE, but the MID tier is NOT bypassed. | ++-----------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| DNS_LIVE_NATNL | DNS Content routing, ut where for "standard" DNS content routing the objects are stored on disk, for this delivery service type the objects are stored | +| | on the RAM disks. Use this for linear TV. The MID tier is NOT bypassed for this type. | ++-----------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| DNS_LIVE | DNS Content routing, same as DNS_LIVE_NATIONAL, but the MID tier is bypassed. | ++-----------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| ANY_MAP | ANY_MAP is not known to Traffic Router. For this deliveryservice, the "Raw remap text" field in the input form will be used as the remap line on the cache. | ++-----------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------+ + +.. Note:: Once created, the Traffic Ops user interface does not allow you to change the delivery service type; the drop down is greyed out. There are many things that can go wrong when changing the type, and it is safer to delete the delivery service, and recreate it. + +.. index:: + Header Rewrite + +.. _rl-header-rewrite: + +Header Rewrite Options and DSCP ++++++++++++++++++++++++++++++++ +Most header manipulation and per-delivery service configuration overrides are done using the `ATS Header Rewrite Plugin <https://docs.trafficserver.apache.org/en/latest/reference/plugins/header_rewrite.en.html>`_. Traffic Control allows you to enter header rewrite rules to be applied at the edge and at the mid level. The syntax used in Traffic Ops is the same as the one described in the ATS documentation, except for some special strings that will get replaced: + ++-------------------+--------------------------+ +| Traffic Ops Entry | Gets Replaced with | ++===================+==========================+ +| __RETURN__ | A newline | ++-------------------+--------------------------+ +| __CACHE_IPV4__ | The cache's IPv4 address | ++-------------------+--------------------------+ + +The deliveryservice screen also allows you to set the DSCP value of traffic sent to the client. This setting also results in a header_rewrite rule to be generated and applied to at the edge. + +.. Note:: The DSCP setting in the UI is *only* for setting traffic towards the client, and gets applied *after* the initial TCP handshake is complete, and the HTTP request is received (before that the cache can't determine what deliveryservice this request is for, and what DSCP to apply), so the DSCP feature can not be used for security settings - the TCP SYN-ACK is not going to be DSCP marked. + + +.. index:: + Token Based Authentication + Signed URLs + +.. _rl-signed-urls: + +Token Based Authentication +++++++++++++++++++++++++++ +Token based authentication or *signed URLs* is implemented using the Traffic Server ``url_sig`` plugin. To sign a URL at the signing portal take the full URL, without any query string, and add on a query string with the following parameters: + +Client IP address + The client IP address that this signature is valid for. + + ``C=<client IP address>`` + +Expiration + The Expiration time (seconds since epoch) of this signature. + + ``E=<expiration time in secs since unix epoch>`` + +Algorithm + The Algorithm used to create the signature. Only 1 (HMAC_SHA1) + and 2 (HMAC_MD5) are supported at this time + + ``A=<algorithm number>`` + +Key index + Index of the key used. This is the index of the key in the + configuration file on the cache. The set of keys is a shared + secret between the signing portal and the edge caches. There + is one set of keys per reverse proxy domain (fqdn). + + ``K=<key index used>`` +Parts + Parts to use for the signature, always excluding the scheme + (http://). parts0 = fqdn, parts1..x is the directory parts + of the path, if there are more parts to the path than letters + in the parts param, the last one is repeated for those. + Examples: + + 1: use fqdn and all of URl path + 0110: use part1 and part 2 of path only + 01: use everything except the fqdn + + ``P=<parts string (0's and 1's>`` + +Signature + The signature over the parts + the query string up to and + including "S=". + + ``S=<signature>`` + +.. seealso:: The url_sig `README <https://github.com/apache/trafficserver/blob/master/plugins/experimental/url_sig/README>`_. + +Generate URL Sig Keys +^^^^^^^^^^^^^^^^^^^^^ +To generate a set of random signed url keys for this delivery service and store them in Traffic Vault, click the **Generate URL Sig Keys** button at the bottom of the delivery service details screen. + +.. index:: + CCR Profile + Traffic Router Profile + +.. _rl-multi-site-origin: + +Multi Site Origin ++++++++++++++++++ +..

To support ``CNAMES`` from domains outside of the Traffic Control top level DNS domain, enter multiple ``HOST_REGEXP`` lines. + +Example: + Example foo. + +.. Note:: In most cases is is sufficient to have just one entry in this table that has a ``HOST_REGEXP`` Type, and Order ``0``. For the *movies* delivery service in the Kabletown CDN, the entry is simply single ``HOST_REGEXP`` set to ``.*\.movies\..*``. This will match every url that has a hostname that ends with ``movies.cdn1.kabletown.net``, since ``cdn1.kabletown.net`` is the Kabletown CDN's DNS domain. + +.. index:: + Static DNS Entries + +.. _rl-static-dns: + +Static DNS Entries +++++++++++++++++++ +Static DNS entries allow you to create other names *under* the delivery service domain. You can enter any valid hostname, and create a CNAME, A or AAAA record for it by clicking the **Static DNS** button at the bottom of the delivery service details screen. + +.. index:: + Server Assignments + +.. _rl-assign-edges: + +Server Assignments +++++++++++++++++++ +Click the **Server Assignments** button at the bottom of the screen to assign servers to this delivery service. Servers can be selected by drilling down in a tree, starting at the profile, then the cache group, and then the individual servers. Traffic Router will only route traffic for this delivery service to servers that are assigned to it. + + +.. _rl-asn-czf: + +The Coverage Zone File and ASN Table +++++++++++++++++++++++++++++++++++++ +The Coverage Zone File (CZF) should contain a cachegroup name to network prefix mapping in the form: :: + + { + "coverageZones": { + "cache-group-01": { + "network6": [ + "1234:5678::\/64", + "1234:5679::\/64" + ], + "network": [ + "192.168.8.0\/24", + "192.168.9.0\/24" + ] + } + "cache-group-02": { + "network6": [ + "1234:567a::\/64", + "1234:567b::\/64" + ], + "network": [ + "192.168.4.0\/24", + "192.168.5.0\/24" + ] + } + } + } + +The CZF is an input to the Traffic Control CDN, and as such does not get generated by Traffic Ops, but rather, it gets consumed by Traffic Router. Some popular IP management systems output a very similar file to the CZF but in stead of a cachegroup an ASN will be listed. Traffic Ops has the "Networks (ASNs)" view to aid with the conversion of files like that to a Traffic Control CZF file; this table is not used anywhere in Traffic Ops, but can be used to script the conversion using the API. + +The script that generates the CZF file is not part of Traffic Control, since it is different for each situation. + +.. _rl-working-with-profiles: + +Parameters and Profiles +======================= +Parameters are shared between profiles if the set of ``{ name, config_file, value }`` is the same. To change a value in one profile but not in others, the parameter has to be removed from the profile you want to change it in, and a new parameter entry has to be created (**Add Parameter** button at the bottom of the Parameters view), and assigned to that profile. It is easy to create new profiles from the **Misc > Profiles** view - just use the **Add/Copy Profile** button at the bottom of the profile view to copy an existing profile to a new one. Profiles can be exported from one system and imported to another using the profile view as well. It makes no sense for a parameter to not be assigned to a single profile - in that case it really has no function. To find parameters like that use the **Parameters > Orphaned Parameters** view. It is easy to create orphaned parameters by removing all profiles, or not assigning a profile directly after creating the parameter. + +.. seealso:: :ref:`rl-param-prof` in the *Configuring Traffic Ops* section. + + + +Tools +===== + +.. index:: + ISO + Generate ISO + +.. _rl-generate-iso: + +Generate ISO +++++++++++++ + + +.. _rl-queue-updates: + +Queue Updates and Snapshot CRConfig ++++++++++++++++++++++++++++++++++++ +When changing delivery services special care has to be taken so that Traffic Router will not send traffic to caches for delivery services that the cache doesn't know about yet. In general, when adding delivery services, or adding servers to a delivery service, it is best to update the caches before updating Traffic Router and Traffic Monitor. When deleting delivery services, or deleting server assignments to delivery services, it is best to update Traffic Router and Traffic Monitor first and then the caches. Updating the cache configuration is done through the *Queue Updates* menu, and updating Traffic Monitor and Traffic Router config is done through the *Snapshot CRConfig* menu. + +.. index:: + Cache Updates + Queue Updates + +Queue Updates +^^^^^^^^^^^^^ +Every 15 minutes the caches will run a *syncds* to get all changes needed from Traffic Ops. The files that will be updated by the syncds job are: + +- records.config +- remap.config +- parent.config +- cache.config +- hosting.config +- url\_sig\_(.*)\.config +- hdr\_rw\_(.*)\.config +- regex_revalidate.config +- ip_allow.config + +A cache will only get updated when the update flag is set for it. To set the update flag, use the *Queue Updates* menu - here you can schedule updates for a whole CDN or a cache group: + + #. Click **Tools > Queue Updates**. + #. Select the CDN to queueu uodates for, or All. + #. Select the cache group to queue updates for, or All + #. Click the **Queue Updates** button. + #. When the Queue Updates for this Server? (all) window opens, click **OK**. + +To schedule updates for just one cache, use the "Server Checks" page, and click the |checkmark| in the *UPD* column. The UPD column of Server Checks page will change show a |clock| when updates are pending for that cache. + + +.. index:: + Snapshot CRConfig + +Snapshot CRConfig +^^^^^^^^^^^^^^^^^ +Every 60 seconds Traffic Monitor will check with Traffic Ops to see if a new CRConfig snapshot was made. If there is a new CRCOnfig, it will apply it to both Traffic Monitor and Traffic Router. See :ref:`rl-crconfig` for more information on the CRConfig file. To create a new snapshot, use the *Tools > Snapshot CRConfig* menu: + + #. Click **Tools > Snapshot CRConfig**. + #. Verify the selection of the correct CDN from the Choose CDN drop down and click **Diff CRConfig**. + On initial selection of this, the CRConfig Diff window says the following: + + There is no existing CRConfig for [cdn] to diff against... Is this the first snapshot??? + If you are not sure why you are getting this message, please do not proceed! + To proceed writing the snapshot anyway click the 'Write CRConfig' button below. + + If there is an older version of the CRConfig, a window will pop up showing the differences + between the active CRConfig and the CRConfig about to be written. + + #. Click **Write CRConfig**. + #. When the This will push out a new CRConfig.json. Are you sure? window opens, click **OK**. + #. The Successfully wrote CRConfig.json! window opens, click **OK**. + + +.. index:: + Invalidate Content + Purge + +.. _rl-purge: + +Invalidate Content +================== +Invalidating content on the CDN is sometimes necessary when the origin was mis configured and something is cached in the CDN caches that needs to be removed. Given the size of a typical Traffic Control CDN and the amount of content that can be cached in it, removing the content from all the caches may take a long time. To speed up content invalidation, Traffic Ops will not try to remove the content from the caches, but it makes the content in accessible using the *regex_revalidate* ATS plugin. This forces a *revalidation* of the content, rather than a new get. + +.. Note:: This method forces a HTTP *revalidation* of the content, and not a new *GET* - the origin needs to support revalidation according to the HTTP/1.1 specification, and send a ``200 OK`` or ``304 Not Modified`` as applicable. + +To invalidate content: + + 1. Click **Tools > Invalidate Content** + 2. Fill out the form fields: + + - Select the **Delivery Service** + - Enter the **Path Regex** - this should be a `PCRE <http://www.pcre.org/>`_ compatible regular expression for the path to match for forcing the revalidation. Be careful to only match on the content you need to remove - revalidation is an expensive operation for many origins, and a simple ``/.*`` can cause an overload condition of the origin. + - Enter the **Time To Live** - this is how long the revalidation force will be active for. It usually makes sense to make this the same as the ``Cache-Control`` header from the origin sets the object time to live in cache (by ``max-age`` or ``Expires``). Entering a longer TTL here will make the caches do unnecessary work. + - Enter the **Start Time** - this is the start time when the force revalidation will be made active. Is pre populated with the current time, leave as is to schedule ASAP. + + 3. Click the **Submit** button. + + +Generate DNSSEC Keys +==================== +TBD
