Contiguous data packets of a single communication session between endpoints are gathered for compression, and at least the payloads are compressed collectively via a single compressible buffer. The original headers, which may or may not be compressed, and the compressed payloads are transmitted from a sending packet compression device to a receiving packet compression device that performs decompression to the compressed payload and may also decompress headers if they have been compressed at the sending end. The original contiguous data packets including headers and payload may be reconstructed at the receiving packet compression device by matching the headers to the corresponding payloads. The reconstructed data packets are injected back into the single communication session, and the presence of the original headers in the reconstructed data packets may thereby maintain the endpoint-to-endpoint authentication protocols.

Compression of data packets while maintaining endpoint-to-endpoint authentication

Optimization of encrypted traffic flowing over a WAN is provided by an arrangement in which WAN compression is distributed between endpoints (i.e., client machines or servers) in a subnet of a hub and branch network and a WAN compression server in the subnet. A client portion of the WAN compression running on each of one or more endpoints interfaces with a disposable local cache of data seen by endpoints in the subnet that is used for compressing and decompressing traffic using dictionary-based compression techniques. The local WAN compression server in a subnet stores a shared central database of all the WAN traffic in the subnet which is used to populate local disposable caches in the endpoints.

Optimizing encrypted wide area network traffic

Various systems and methods described above permit a user's content experience (e.g. music playing experience) to be monitored and for metadata describing this experience to be collected. This metadata can be dynamically updated as a user experiences media content and then used to impart to the user a personalized experience that is tailored to that specific user. A user's metadata can, in some instances, provided across a wide variety of computing devices on which the user may experience the media content, thus standardizing the user's personalized media experience. In addition, intelligent or 'smart' playlists can be provided which, in some instances, can be dynamically and automatically updated to reflect current user experiences, thus providing a highly personalized and enjoyable content experience.

Methods and apparatuses are provided for use with a client and server device connected through a communication link. The client device sends a startup request to the server device. The startup request identifies a streamable media content that is to be provided to the client device, a communication link bandwidth associated with the communication link, and an amount of the desired streamable media content that is to be provided at a bitrate greater than the encoded bitrate but no greater than about the communication link bandwidth. The server device buffers at least the amount of the streamable media content, and transmits the amount of the buffered streamable media content at the higher bitrate. The server device locates a discrete rendering point in the amount of the buffered streamable media content and initiates transmission beginning with the discrete rendering point. After transmitting the amount of the buffered streamable media content, the server device transmits subsequent portions of the streamable media content to the client device at a bitrate about equal to the encoded bitrate. The client device buffers received streamable media content, and subsequently renders the buffered streamed media content.

Methods and systems for providing playlists

A system and method for organizing and sorting targets received in a referral response and for realizing a target fail-back and a target priority policy in a distributed file system is provided. In one embodiment, a sorting method includes receiving a referral response in the form of a list of targets that are sorted into bounded sets. Having a sorted referral response in bounded sets provides a basis for implementing a target fail-back and a target priority policy. The computer system may select a target from a sorted list of targets sorted according to site-cost and/or target priority. Then, the computer system may determine if the set target is associated with a more preferred target when compared to all available targets in the sorted list and if not, switch back to a more preferred target.
