Abstract: A system includes a media optimizer that adaptively generates and transmits a modified manifest file based on an original manifest file corresponding to an associated media asset from a content provider in response to a media content request from a client for the associated media asset. The original manifest file specifies bitrates. The media optimizer extracts parameters associated with the media content request and applies bitrate policies based on the extracted parameters to adaptively modify the original manifest file to generate the modified manifest file. The media optimizer is further configured to transmit the modified manifest file to the client for selection by the client of a bitrate associated with delivery of the associated media asset.

Abstract: Particular embodiments provide an access gateway that facilitates communication between a plurality of access technologies. The access gateway facilitates data communication with an access terminal through a bearer path. A radio resource manager is configured to provide radio resource management functions for the communications. The radio resource manager is decoupled from the bearer path and provides control of radio transmission characteristics for the bearer path to the gateway. Because the radio resource manager is not in the bearer path, the access gateway may be access technology agnostic. Thus, the access gateway does not need to have access-specific modules based on the radio technology for each bearer path.

Abstract translation: 具体实施例提供了便于多个接入技术之间的通信的接入网关。 接入网关便于通过承载路径与接入终端的数据通信。 无线资源管理器被配置为为通信提供无线电资源管理功能。 无线电资源管理器与载体路径解耦，并提供对网关承载路径的无线电传输特性的控制。 由于无线电资源管理器不在承载路径中，所以接入网关可能是接入技术不可知的。 因此，接入网关不需要基于用于每个承载路径的无线电技术的访问专用模块。

Abstract: In one embodiment, a method includes receiving capability information from an end host at a centralized security matrix in communication with a firewall and a plurality of end hosts, verifying at the centralized security matrix, a trust level of the end host, assigning at the centralized security matrix, a firewall function to the end host based on the trust level and capability information, and notifying the firewall of the firewall function assigned to the end host. Firewall functions are offloaded from the firewall to the end hosts by the centralized security matrix. An apparatus and logic are also disclosed herein.

Abstract: Techniques are presented herein for optimizing and load balancing network traffic exchanged between devices in a network environment. At a first device in a cluster of devices in a network, a packet is received from a second device in the cluster. The packet comprises identifier information that is assigned to the first device. The identifier information is reassigned to the second device in the cluster such that subsequent packets with the identifier information are sent directly to the second device. A mapping table is updated to indicate that the identifier information is reassigned to the second device.
