whitepaper However, the presence of Network Address Translators (NAT) and firewalls challenges the deployment of ESM and other such systems because NATs and firewalls impose fundamental connectivity constraints.
[11 May 2008]
whitepaper Together with many security enhancements, however, the use of NATs/Firewalls has raised a number of new issues and problems. Most of them related to the complex NAT/Firewall traversal problem, where applications and services are blocked to connect...

whitepaper The combined approach mitigates problems associated with traceroute-based topology discovery, including abuse reports, spurious edge inference from multi-path routing, unresolved IP aliases, long network timeouts, and link discovery behind NATs...
[26 Dec 2007]
whitepaper This is motivated by the friendliness of NATs and firewalls towards TCP as opposed to UDP as well as by recent improvements in Internet's bandwidth and loss rates. This paper examines the feasibility of sending real-time CBR workloads over TCP.
[06 Nov 2007]
whitepaper So far, this work has been limited to UDP because of the assumed impossibility of establishing TCP connections through NAT, and because of the difficulty of predicting port assignments on certain common types of NATs.
[06 Nov 2007]
whitepaper The authors are able to create direct TCP connections between two hosts which are both located behind typical NATs designed for small networks. Firewalls and Network Address Translation (NAT) devices are becoming increasingly prevalent, and they...
[30 Oct 2007]
whitepaper It is named NAT because the load balancer NATs packets traveling between two subnets, much like a firewall or a router performing a NAT. NAT-based SLB network architecture is, by definition, any SLB network implementation where the IPs of the VIPs...

News Like other customers picking up gongs from SAP, NATS senior programme manager Alistair Godbold said one of the key things was sponsorship from the top: "We had our finance director, programmes director and HR director on the project board.
[25 Jun 2007]
whitepaper To ensure secure transfers, the authors describe a novel scheme that verifies encoded blocks on-the-fly and analyze its performance and also study the effect of peers behind NATs and firewalls and show the robustness of the system to large number...
[03 May 2006]
whitepaper The combination of IPv6 and Teredo allows Windows-based hosts to use IPv6-enabled applications that require unsolicited, incoming, IPv6 traffic and global addressing over NATs. The combination of IPv6, Teredo, and a host-based, stateful, IPv6...

News National Air Traffic Services (Nats) said its Flight Data Processing (FDP) system at West Drayton developed a fault today at 09:30(BST) but was restored to full operations by 09:50(BST). Nats said restrictions that were imposed on flights as a...
[24 Aug 2005]
whitepaper This paper summarises the range of measures taken to improve CAPEX procurement at NATS. A recent procurement improvement programme has taken a very broad look at all supply chain management practices at NATS, including those relating to...
[24 Jun 2005]
whitepaper Teredo, also known as IPv4 network address translator (NAT) traversal for IPv6, is an IPv6 transition technology that provides address assignment and host-to-host automatic tunneling for unicast IPv6 connectivity when IPv6/IPv4 hosts are located...

News Jasomi Networks makes equipment to solve the "NATs in the firewall" issue. With today's media traffic, there are challenges when trying to penetrate firewalls and NATS," he said. Microsoft is beefing up its corporate instant messaging product line...
[07 Mar 2005]
News According to a spokesman from NATS the problem was resolved by 19:03(GMT) and a spokeswoman for British Airports Authority told silicon.com the backlog of delayed flights had been cleared by around 20:00(GMT).
[17 Feb 2005]
whitepaper The paper shows how different slaves can be constructed to tunnel through NATs and firewalls, as well as to improve the robustness of the routing infrastructure and to provide efficient and resilient implementations for features such as multicast...
[16 Oct 2004]
News BT has landed a £32m, nine-year contract from National Air Traffic Services (NATS) for the provision of virtual private network (VPN) technology that will link its radar, communications and air traffic control sites.
