Patent number: 9497284Abstract: 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.Type: GrantFiled: November 4, 2014Date of Patent: November 15, 2016Assignee: AKAMAI TECHNOLOGIES, INC.Inventors: Michael M. Afergan, Charisma J. LaFleur, Duke P. Hong, Satish B. Rao

Patent number: 8477630Abstract: A routing mechanism operable in a distributed networking environment, such as a content delivery network (CDN), provides improved connectivity back to an origin server, especially for HTTP traffic. The technique enables an edge server operating within a given edge region to retrieve content (cacheable, non-cacheable and the like) from an origin server more efficiently by selectively routing through the network's own nodes, thereby avoiding network congestion and hot spots. The technique enables an edge server to fetch content from an origin server through an intermediate edge server or, more generally, enables an edge server within a given first region to fetch content from the origin server through an intermediate edge region.Type: GrantFiled: June 4, 2012Date of Patent: July 2, 2013Assignee: Akamai Technologies, Inc.Inventors: Claudson F. Bornstein, Timothy K. Canfield, Gary L. Miller, Satish B. Rao, Ravi Sundaram

Patent number: 8194538Abstract: A routing mechanism, service or system operable in a distributed networking environment. One preferred environment is a content delivery network (CDN) wherein the present invention provides improved connectivity back to an origin server, especially for HTTP traffic. In a CDN, edge servers are typically organized into regions, with each region comprising a set of content servers that preferably operate in a peer-to-peer manner and share data across a common backbone such as a local area network (LAN). The inventive routing technique enables an edge server operating within a given CDN region to retrieve content (cacheable, non-cacheable and the like) from an origin server more efficiently by selectively routing through the CDN's own nodes, thereby avoiding network congestion and hot spots.Type: GrantFiled: April 18, 2011Date of Patent: June 5, 2012Assignee: Akamai Technologies, Inc.Inventors: Claudson F.

Patent number: 6078688Abstract: Segmentation of an image into separate regions is useful in many computer vision problems. The separate regions may be represented by their enclosing contours. A planar graph is constructed for each image. The optimal contour is determined by the assignment of edge costs and face weights of the graph. An algorithm is provided such that given a planar graph G = (V,E) where V is a set of nodes, E is a set of edges and each edge e is provided with a non-negative cost c(e) and each face f of the planar graph is provided with a non-negative weight w(f), and given a single node v in G and single face F adjacent to v which is viewed as the exterior face, then find a directed path P in G that starts and finishes at v and minimizes ##EQU1## where cost(P) is defined as the length of the path under c, and weight (P) is the weight of the faces that are separated from F by P. The contour that minimizes .zeta. is the optimal contour.Type: GrantFiled: August 23, 1996Date of Patent: June 20, 2000Assignee: NEC Research Institute, Inc.Inventors: Ingemar J. Cox, Satish B. Rao

Patent number: 5737233Abstract: A VLSI circuit layout method includes defining a circuit to be designed in terms of a set of components V and a set of nets H connecting the components. A cost function is defined using a spreading function to define a cost of a VLSI circuit layout. A simulated annealing is applied to the cost function to produce a VLSI circuit layout having a minimal cost function. The resulting VLSI circuit layout requires minimal area.Type: GrantFiled: January 5, 1996Date of Patent: April 7, 1998Assignee: NEC Research Institute, Inc.Inventor: Satish B. Rao
