The Path Computation Element (PCE) provides functions of path computation in support of traffic engineering (TE) in Multi-Protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks.

Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering (TE) Label Switched Paths (LSPs) may be computed by Path Computation Elements (PCEs). Where the TE LSP crosses multiple domains, such as Autonomous Systems (ASes), the path may be computed by multiple PCEs that cooperate, with each...

Several protocols have been specified in the Routing Area of the IETF using a common variant of the Backus-Naur Form (BNF) of representing message syntax. However, there is no formal definition of this version of BNF.

This document describes a Fully-Specified Forward Error Correction (FEC) Scheme for the Reed-Solomon FEC codes over GF(2^^m), where m is in {2..16}, and its application to the reliable delivery of data objects on the packet erasure channel (i.e., a communication path where packets are either received without any...

Disclosed is a framework that provides for specification of handling the following: -intercepting an incoming request -making an authentication decision -allowing multiple authentication methods to be executed for the same request -handling the request if an authentication is unsuccessful -populating user...

Disclosed is a method that merges multiple email contents within a same mail thread into one single email. During the merging process, only the delta region of the newly replied or forwarded mails will be synchronized and inserted into the original mail, thus, avoiding wasting disk spaces in saving multiple copies...

The idea in this invention is NOT to extract the File at one stretch but rather extract the File in Blocks/Chunks based on the availability of the Free Space in the File System.Block/Chunk size is not fixed. It is calculated dynamically based on the availability of free space in the file system.

Today, so-called "redundant fan" is to combine two independent fans in to a single package. On logistic point of view, these two fans are still independent. System still needs signals to control and sense these two independent fans. However, these two fans are just inside the same housing. In this disclosure, a...
