Abstract:
1. A method for providing a production upgrade of a component in a multiprotocol gateway, from an older version of the component, to a new version which includes modified functionality relative to the older version, the method comprising: providing a multiprotocol gateway which executes on one or more processors, and which includes a plurality of components; receiving a first request to the multiprotocol gateway, wherein the first request is directed to a particular component; directing the first request to an older version of the component; upgrading the component, by deploying a new version of the component alongside the older version within the gateway, and by providing a schema accessible to both versions, wherein the schema defines a structure of state information which is associated with the older version and consumed by the new version, so that the state information is simultaneously accessible by both versions, wherein the new version adds new attributes to the schema; enforcing a service level agreement across multiple versions of a plug-in associated with the component, wherein a shared state is maintained across the multiple versions; receiving a second request to the gateway, wherein the second request is received after the new version of the component has been deployed and while the older version of the component remains operational; routing the second request to the new version of the component and continuing to receive new traffic to the gateway uninterrupted; and retiring the older version of the component when existing sessions using the older version are completed.
