Inter Domain Routing

An autonomous system (AS) is the collection of networks having the same set of routing policies. Each AS has administrative control to its own inter-domain routing policy. Computer networks consisting of a bunch of AS's with different routing will not be able to interconnecttion one another. This is causes communication in the network to be inhibited. For that we need a protocol that can connect each different AS. Border Gateway Protocol (BGP) is an inter-domain routing protocol i.e. between different AS  that is used to exchange routing information between them. In a typical inter-network (and in the Internet) each autonomous system designates one or more routers that run BGP software. BGP routers in each AS are linked to those in one or more other AS. The ability to exchange table routing information between Autonomous System (AS) is one of the advantages BGP. BGP implements routing policies based a set of attributes accompanying each route used to pick the “shortest” path across multiple ASs, along with one or more routing policies. BGP uses an algorithm which cannot be classified as a pure "Distance Vector", or pure "Link State". It is a path vector routing protocol as it defines a route as a collection of a number of AS that is passes through from source AS to destination AS. This paper discusses the implementation of the BGP routing protocol in the network that have different AS in order to interconnect. Its application using Packet Tracer 7.0 software for prototyping and simulating network. So that later can be applied to the actual network. Based on experiments that have been carried out, the BGP routing protocol can connect two routers that have different autonomous system.

Prediction Capability

Accurate prediction of network paths between arbitrary hosts on the Internet is of vital importance for network operators, cloud providers, and academic researchers. We present PredictRoute, a system that predicts network paths between hosts on the Internet using historical knowledge of the data and control plane. In addition to feeding on freely available traceroutes and BGP routing tables, PredictRoute optimally explores network paths towards chosen BGP prefixes. PredictRoute's strategy for exploring network paths discovers 4X more autonomous system (AS) hops than other well-known strategies used in practice today. Using a corpus of traceroutes, PredictRoute trains probabilistic models of routing towards prefixes on the Internet to predict network paths and their likelihood. PredictRoute's AS-path predictions differ from the measured path by at most 1 hop, 75% of the time. We expose PredictRoute's path prediction capability via a REST API to facilitate its inclusion in other applications and studies. We additionally demonstrate the utility of PredictRoute in improving real-world applications for circumventing Internet censorship and preserving anonymity online.

Operating Temperature Range

The vast majority of electronic devices on-Board Russian spacecraft is placed on a temperature-controlled mounting surface is ON, however, in some tasks there is a necessity to place a separate electronic units out thermostated panels on remote spacecraft design. The article presents an autonomous system of providing thermal regime of electronic blocks of spacecraft and objects of space technology that require maintaining the operating temperature and are unable to be installed on the thermostatic landing surfaces of spacecraft. The proposed autonomous system of providing thermal regime can operate autonomously in the extended operating temperature range of the installation surface from -80 to +80 °C when the supply voltage changes in the range from 75 to 550% of the nominal value. The review of the existing solutions is presented, the substantiation of the proposed decision is given, the structural scheme of autonomous system of providing thermal regime is given and its description and an example of application is given.
