Abstract: A method is provided for automating management of automatic renewal of a public key infrastructure (PKI) certificate issued by a certificate authority (CA) for a subscriber. The method includes steps of causing the subscriber to (i) transmit a first alert to a management entity for initiating renewal of the PKI certificate, and (ii) transmit a certificate signing request (CSR) to a registration authority (RA) for issuance of a renewal certificate. The method further includes steps of (iii) transmitting, from the RA to the CA, the CSR signed by the RA, (iv) receiving, at the RA from the CA, an issued renewal certificate signed by the CA, (v) sending, from the RA to the subscriber, the issued renewal certificate signed by the CA, and (vi) causing the subscriber to transmit a second alert to a management entity indicating renewal of the PKI certificate.

Abstract: Service discovery and other operations related to enabling devices to announce, discover or otherwise control their services and/or the services offered or available from other devices is contemplated. The service discovery may facilitate service discovery for services sourced from devices inside and outside of a network and/or from devices having incompatible messaging capabilities.

Abstract: Authenticating devices utilizing Transport Layer Security (TLS) protocol to facilitate exchange of authentication information or other data to permit or otherwise enable access to services requiring authentication credentials, certificates, tokens or other information. The authentication may utilize Digital Transmission Content Protection (DTCP) certificates, Diffie-Hellman (DH) parameters or other information available to the authenticating devices, optionally without requiring device requesting authentication to obtain an X.509 certificate.

Abstract: Minimizing latency when streaming media, such as but not necessary limited to limiting or otherwise ameliorating polling latency, network response latency and/or other communication related latencies, is contemplated. The latency minimization may include facilitating long polling or otherwise facilitating instantaneously transmitting requested media once available.

Abstract translation: 考虑到流媒体（例如但不限于限制或以其他方式改善轮询延迟，网络响应等待时间和/或其他通信相关潜伏期）的最小化等待时间。 等待时间最小化可以包括促进长轮询或以其他方式促进一旦可用的瞬时发送所请求的媒体。
