A Service record (SRV record) is a specification of data in the Domain Name System defining the location, i.e. the hostname and port number, of servers for specified services. It is defined in RFC , and its type code is . org. connection order as specified by RFC 5, in that all priorities and Presence Protocol (XMPP): Core >. The following are IETF Requests for Comments (RFC). (DNS NCACHE); RFC Domain Name System Security Extensions; RFC A.

SRV record

The sum of all three values isso bigbox. An example Ketf record in textual form that might be found in a iietf file might be the following:. This might be a machine in another physical location, presumably not vulnerable to anything that would cause the first three hosts to become unavailable.

In the following example, both the priority and weight fields are used to provide a combination of load balancing and backup service.

See the Oracle Technology Network http: Oracle WebLogic Communication Services is supported for production use on the operating system, hardware, and JVM combinations described shown in http: This functionality can be implemented as part of the application.

If a service has multiple SRV records with the same priority value, clients should load balance them in proportion to the values of their weight fields. The first three records share a priority of 10, so the weight field’s value will be used by clients to determine which server host and port combination to contact. Additional RAM is required to support iettf throughput requirements of most production installations.

Oracle WebLogic Communication Services supports backward compatibility as described in this specification. SRV records are also used by Outlooktfc Macintosh BIG-IP load balancer, versions 9.

Current load of servers is not taken into account, unless TTL values are low enough around a minute or lower that the priority rfd weight values can be quickly updated. Oracle WebLogic Communication Services supports applications that conform to this specification, but it does not provide a means of storing the ServiceRoute established during registration.

In Microsoft Windows clients query for SRV records to determine the domain controller for a given service.

Gigabit Ethernet connections are required between engine and SIP data tier servers for most production deployments. Yes Platform See http: Clients should use the SRV records with the lowest-numbered priority value first, and fall back to records of higher value if the connection fails. Basic and Digest Access Authentication. Oracle WebLogic Communication Services does enforce uniqueness.

Feature development is prioritized according to general market trends, both observed and predicted. Oracle WebLogic Communication Services supports the ‘X-3GPP-Asserted-Identity extension-header’ for use in applying access control and authorization constraints within the integrated security framework.


In cases where certain specifications are obsolete or where Internet drafts are formalized as ‘Request For Comments’ standards, Oracle WebLogic Communication Services places priority 7282 compliance with those specifications.

Retrieved from ” https: The level of compliance is defined as follows: The load balancing provided by SRV records is inherently limited, since the information is essentially static. Webarchive template wayback links Wikipedia articles needing clarification from September Pages using RFC magic links.

Other than rcf exceptions noted, Oracle WebLogic Communication Services does not impose uetf restrictions on implementing applications or functions that are compliant with those associated with the Application Server entity described in the specification.

SRV records are common in conjunction with the 27882 standardized communications protocols: The priority given here is 0, and the weight is 5.
