Abstract: This disclosure provides for a network element (in the middle) to inject enrichments into SSL connections, and for taking them out. This network element is sometimes referred to herein as a “middle box.” In the context of layered software architecture, this solution preferably is implemented by a library that operates below the SSL layer and above the TCP sockets layer at the two endpoints of the SSL connection. Preferably, the SSL enrichments are implemented as SSL/TLS records.

Abstract: Origin offload is a key performance indicator of a content delivery network (CDN). This patent document presents unique methods and systems for measuring origin offload and applying those measurements to improve the offload. The techniques presented herein enable resource-efficient measurement of origin offload by individual servers and aggregation and analysis of such measurements to produce significant insights. The teachings hereof can be used to better identify root causes of suboptimal offload performance, to tune CDN settings and configurations, and to modify network operations, deployment and/or capacity planning. In addition, discussed herein are improved metrics showing offload in relation to the maximum achievable offload for the particular traffic being served.

Abstract: A method of content delivery in a content delivery network (CDN), where the CDN is deployed, operated and managed by a content delivery network service provider (CDNSP). The CDN comprises a set of content servers and a domain name system (DNS). For a given content provider, a determination is first made whether the content provider has “cold content” delivery requirements by evaluating one or more factors that include: total content size, size of content objects expected to be served, uniqueness of content, total number of content objects, and a percentage of the total content size that is expected to account for a given percentage of traffic. Upon a determination that the content provider has cold content delivery requirements, a subset of the CDN content servers are configured to implement a set of one or handling rules for managing delivery of the cold content from the CDN content servers.

Abstract: This disclosure provides for a network element (in the middle) to inject enrichments into SSL connections, and for taking them out. This network element is sometimes referred to herein as a “middle box.” In the context of layered software architecture, this solution preferably is implemented by a library that operates below the SSL layer and above the TCP sockets layer at the two endpoints of the SSL connection. Preferably, the SSL enrichments are implemented as SSL/TLS records.

Abstract: A method of content delivery in a content delivery network (CDN), where the CDN is deployed, operated and managed by a content delivery network service provider (CDNSP). The CDN comprises a set of content servers and a domain name system (DNS) associated with a CDN namespace. For a given content provider, a determination is first made whether the content provider has “cold content” delivery requirements by evaluating one or more factors that include: total content size, size of content objects expected to be served, uniqueness of content, total number of content objects, and a percentage of the total content size that is expected to account for a given percentage of traffic.
