Failover handling in a content node of a content delivery network

A computer apparatus to operate a content node in a content delivery network, the computer apparatus comprising:

• one or more non-transitory computer readable storage media that store the processing instructions;
• processing instructions stored on the one or more non-transitory computer readable storage media that direct a processing system, when executed by the processing system, to:
• in response to obtaining a communication from a control node, the communication corresponding to a content request issued by an end user device previously handled by a second content node, determine if the communication includes a synchronization packet and identify connection information for the communication;
• if the communication does not include a synchronization packet, determine if a match exists between the connection information for the communication and connection information stored in at least one data structure;
• if a match exists, handle content delivery for the end user device;
• if a match does not exist, forward the communication to the second content node.

A content delivery network to transition communications to a content node from a second content node, the system comprising:

• a control node configured to:
• transfer a communication to the content node, the communication corresponding to a content request issued by an end user device previously handled by the second content node;
• and
• the content node configured to:
• receive the communication;
• determine if the communication includes a synchronization packet and identify connection information for the communication;
• if the communication does not include a synchronization packet, determine if a match exists between the connection information for the communication and connection information stored in at least one data structure;
• if a match exists, handle content delivery for the end user device;
• if a match does not exist, forward the communication to the second content node.
