Redundancy and Resilience Sample Clauses

Redundancy and Resilience allows for high availability and speedy recovery Ensuring to allow users to benefit from uninterrupted, continuous service, all AirportConnect Open components are redundant. From multi-path wiring to multiple gateways, redundant switches and servers to RAID disk arrays on servers and interleaved workstations across multiple VLANs, your AirportConnect Open installation is protected to ensure that no single component failure can compromise the overall service and ensures 24x7 system operation. In addition to providing a fully redundant system, software resilience ensures that, for example, should a server or gateway fail, your users may continue to check-in passengers. Users are able to control the system’s resiliency to meet their own needs if required – for example, they will be able to select and direct printing to an alternate boarding pass or bag tag printer in case the original printer jams or becomes inoperable. Regular backups and replications are a component of AirportConnect Open’s overall recovery strategy and can take place without causing any interruption to service. The system is protected with a network backup server that employs a ‘one-touch’ restore function to ensure optimized recovery in the event of failure.

Redundancy and Resilience. The redundancy and resilience mechanisms defined in [1] and [2] and [3] apply. In addition the MSF architecture requires that bandwidth managers (Gate Controllers) and MSF edge nodes (Media Gateways) use the Gate Recovery Information package as follows. When the bandwidth manager requests a resource from the edge node it shall include a unique call reference allocated by the call agent and stored in the Gate Recovery Information package’s “gri” property. This call reference shall include sufficient information to identify the call agent, and the call id within that call agent. It may contain additional information to assist the call agent and or the bandwidth manager in the event of network failure. In the unlikely event that a bandwidth manger completely fails and must recover from zero state it must audit its associated MSF edge nodes in order to discover the state of individual gates that it had previously set. In an MSF architecture this is complicated because many call agents request bandwidth from a bandwidth manager so although a single edge node is controlled by a single bandwidth manager the gates at that edge node may have been set up at the request of many different call agents. When the bandwidth manager audits the edge node it is able to retrieve the gate recovery information stored for each gate. This enables it to determine which call agent configured the gate and the call id associated with the gate. The bandwidth manager can then audit the various call agents, using a protocol such as NRCP [4] and correlate the call ids at the open gates with the call ids of currently in progress calls. Gates which still correspond to an active call shall be kept open and gates for which no active call exists shall be deleted. If an integrated call agent/bandwidth manager is used then there is no requirement to use the gate recovery information package in this way because only one call agent can request gates be established at a particular edge node. 8 Firewall and NAT traversal This IA enables NAT traversal for customer traffic sent into an MSF network, however the control interface defined by this IA is intended for use within a private IP network and is therefore not required to traverse firewalls or NAT devices.

Redundancy and Resilience. Redundancy and resilience has two aspects with respect to Media Servers: redundancy of the Media Server itself and redundancy of the Media Server's control agent. Redundancy of the Media Server means that any failure of a Media Server component results in a transparent recovery by the Media Server. For a hardware failure, the Media Server switches transparently and immediately to a hot standby component, which then behaves to the outside world like the previous component did (e.g., takes over IP addresses, etc.). Redundancy of the Media Server is optional. Redundancy of the Media Server's control agent means that the control agent (e.g., Call Agent or Application Server) controlling the Media Server may fail. There are two cases. In the first case, a hot standby control agent takes over transparently (e.g., takes over IP addresses, etc.) and immediately, and the Media Server is not aware of the failure. In the second case, the switchover to the new control agent is not transparent to the Media Server and the new control agent must explicitly inform the Media Server of the handover. The Media Server must provide support only for the second case, the feature for which is called "control agent failover support". The Internet Draft [MGCPRED] addresses this second case by providing the control agent with a command that tells the Media Server to transfer ownership of resources (e.g., endpoints, connections) from one control agent to another. Currently, there is no equivalent for SIP. 10 Overload control Overload control is not in scope for this IA.

Redundancy and Resilience. This section describes the redundancy and resilience requirements. ▪ The AG shall have better than 99.999% availability in order to achieve the same service level agreements as offered on current PSTN networks. ▪ The architecture of an AG shall be redundant such that no single point of failure can deprive all that AG's customers of service. ▪ The AG shall support a primary network link and at least one secondary link to ensure that no loss of service occurs under primary link failure. When failure does occur then the AG shall switch over to one of the protected links. The switch over shall occur within tens of milliseconds in order to minimum disruption of media and signaling traffic. ▪ Under fault conditions the AG shall be capable of re-registering with a secondary “Call Agent”.
