Abstract: The size and location of an envelope of a data block are included in the posting to a second device of a descriptor list entry for the data block, thus allowing the second device to read the data block without having to first read the descriptor list entry. This envelope may be the same size and location of the data block, or this envelope may be larger than the data block. For example, as the size of the posted register may not be large enough to also store all of the bits required to specify the exact size and position of the data block, a larger data block envelope is defined without specifying the exact low order bits of the size and/or location of the data block envelope.

Abstract: A content delivery network (CDN) edge server is provisioned to provide last mile acceleration of content to requesting end users. The CDN edge server fetches, compresses and caches content obtained from a content provider origin server, and serves that content in compressed form in response to receipt of an end user request for that content. It also provides “on-the-fly” compression of otherwise uncompressed content as such content is retrieved from cache and is delivered in response to receipt of an end user request for such content. A preferred compression routine is gzip, as most end user browsers support the capability to decompress files that are received in this format. The compression functionality preferably is enabled on the edge server using customer-specific metadata tags.
