Abstract: Packet loss mitigation may be provided. First, queue control data may be sent to a first container and then a route may be stalled after sending the queue control data. The route may correspond to a data path that leads to the first container. Next, modified queue control data may be received from the first container and the first container may be deleted safely with empty queues, preventing packet loss in response to receiving the modified queue control data.

Abstract: Temporal transaction locality in a stateless environment may be provided. First, a current message having an identifier may be received. Next, it may be determined, based on the identifier, that the current message is associated with a transaction. Then, in response to determining that the current message is associated with the transaction, the current message may be sent to a target service instance corresponding to the transaction.

Abstract: An example system and method for facilitating virtual cable modem termination system (VCMTS) migration in cable modem network environments is provided and includes spawning, by an orchestration component executing using a processor, a first instance of a virtual network function (VNF) on a first server in a cable modem network, storing state of the first instance as state information in an external database, spawning a second instance of the VNF on a different second server, synchronizing state of the second instance with the state information stored in the external database, and deleting the first instance. In specific embodiments, the VNF comprises a VCMTS.

Abstract: An example system and method for facilitating virtual cable modem termination system VCMTS redundancy in cable modem network environments is provided and includes spawning a first instance of a virtual network function (VNF) on a first server in a cable modem network, spawning a second instance of the VNF on a different second server, configuring the second instance to be communicatively coupled to the first instance in a same subnet of the network, and synchronizing (e.g., copying, coordinating, matching, etc.) state between the first instance and the second instance. In specific embodiments, the VNF comprises a VCMTS.
