摘要
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.
說明書
The present disclosure relates generally to stateless environments.
A Hybrid Fiber-Coaxial (HFC) network is a broadband network that combines optical fiber and coaxial cable. It has been commonly employed globally by cable television operators. In a hybrid fiber-coaxial cable network, television channels are sent from a cable system's distribution facility to local communities through optical fiber trunk lines. At the local community, a box translates the signal from a light beam to electrical signal, and sends it over cable lines for distribution to subscriber residences. The optical fiber trunk lines provide adequate bandwidth to allow future expansion and new bandwidth-intensive services.
The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate various embodiments of the present disclosure. In the drawings:
