Assignee:

Conexant Systems, Inc. - Red Bank NJ

International Classification:

G01R 31/08

US Classification:

370248, 370249

Abstract:

A method for actively detecting link failures on a high availability backplane architecture. The backplane system includes redundant node boards operatively communicating with redundant switch fabric boards. Uplink ports of the node boards are logically grouped into trunk ports at one end of the communication link with the switch fabric boards. A probe packet is sent, and a probing timer is set whenever either a specified number of bad packets are received, or an idle timer expires. If a response to the probe packet is received before the probe timer expires then the link is deemed valid, otherwise the link is presumed to have failed. Preferably, either the node boards or the switch fabric boards are configured to properly handle a probe pack, which preferably has identical source and destination addresses.

Abstract:

Disclosed is an apparatus and method for storing and searching computer node addresses in a computer network system. In one embodiment, the apparatus comprises a frame forwarding device such as a switch. The switch includes two MAC address tables including a primary MAC address table and secondary MAC address table both for storing and searching MAC addresses. The primary table stores records that contain compressed values of MAC addresses. The records are contained in storage locations that are referenced using the compressed value of the MAC address as a search index. In order to account for searching collisions that may result from different MAC addresses compressing to the same value, each record in the primary address table is linked to a chain of records in the secondary table. The records in the secondary table store the full value of the MAC address. Each chain of records in the secondary address table contains MAC addresses the present invention.

International Classification:

G01R 31/08
G06F 11/00

US Classification:

370216, 370225

Abstract:

A hardware-based failover scheme enabling rapid end-to-end recovery is provided. Hardware logic periodically generates, transmits, receives, and processes heartbeat packets, sent from one end of the communications network to another, and then returned back. If a communications network node or communications link failure is being experienced along the transport path, then the hardware logic rapidly swaps the affected traffic conveyed to a pre-established backup transport path, typically within microseconds. Advantages are derived from the rapid failover effected end-to-end which enables continued delivery of provisioned communications services improving the resiliency and/or availability of a communications network.

Abstract:

A high availability backplane architecture. The backplane system includes redundant node boards operatively communicating with redundant switch fabric boards. Uplink ports of the node boards are logically grouped into trunk ports at one end of the communication link with the switch fabric boards. The node boards and the switch fabric boards routinely perform link integrity checks when operating in a normal mode such that each can independently initiate failover to working ports when a link failure is detected. Link failure is detected either by sending a link heartbeat message after the link has had no traffic for a predetermined interval, or after receiving a predetermined consecutive number of invalid packets. Once the link failure is resolved, operation resumes in normal mode.

US Classification:

370/352000, 370/401000

Abstract:

Architecture for processing routing information in a data network. A set of routing information entries is provided in a routing database of a first storage location. A subset of the routing information entries is created in a second storage location, which subset of the routing information entries are in the structure of an IP tree. Packet routing information of an incoming packet is extracted, which packet routing information includes multiple byte parts. The second storage location is accessed to compare the multiple byte parts of the packet routing information sequentially with respective entries of the subset of routing information entries to determine forwarding information. The subset of routing information in the second location is adjusted dynamically in response to the availability of the packet routing information in the subset of routing information entries.

Abstract:

A data switching engine is provided. The data switching engine includes a switching processor used for data traffic forwarding and an traffic management processor used for data traffic management. The switching processor retains all functionality of currently deployed data switching equipment as it relates to data switching and forwarding. The traffic management processor performs data traffic characterization, statistics extraction, service level agreement enforcement, etc. The use of the traffic management processor reduces computational loads otherwise imposed on the switching processor while maintaining or surpassing levels of service provided by currently deployed data switching equipment.
