摘要： A method is disclosed for application layer message-based load balancing. According to one aspect, when a network element receives one or more data packets that collectively contain an application layer message, the network element determines a message classification to which the application layer message belongs. Using a load-balancing algorithm that is mapped to the message classification, the network element selects a server from among a plurality of servers, and sends the message toward that server. According to one "adaptive" load-balancing algorithm, the network element selects the server based on multiple servers' average historical response times and average outstanding request wait times. The network element continuously maintains these statistics for each server toward which the network element has sent requests. The network element tracks response times by recording how much time passes between the sending of a request to a server and the receiving of a corresponding response from that server.

摘要： A system for multi-chassis interconnection and a method for chassis connection are disclosed. The system includes at least three chassis; each chassis includes a first switch fabric unit (SFU) and a second SFU; the first SFU in the first chassis is connected to the first SFU in other chassis; and the second SFU in the second chassis is connected to the second SFU in other chassis. In the embodiments of the present invention, different SFUs in the chassis of the multi-chassis interconnection system are connected to different main chassis, thus overcoming the technical defect in the prior art that other chassis in the multi-chassis interconnection system are unable to exchange data when the main chassis is faulty. Therefore, in the embodiments of the present invention, other chassis in the multi-chassis interconnection system can still exchange data normally when the main chassis is faulty.

摘要： A communication apparatus is configured to include first and second cards, and a card-to-card link connecting the cards. Each card is communicably connected to another communication apparatus through a route connected to the card. One of the cards is determined to be a primary card that controls data transmission between the communication apparatus and another communication apparatus, and the other card is determined to be a secondary card controlled by the primary card. The primary card establishes a primary data-path for transmitting primary data, using one of the first and second routes connected to the primary card. The primary card further establishes a secondary data-path for transmitting secondary data, using the card-to-card link, the secondary card, and the other one of the first and second routes connected to the secondary card.

摘要： The subject matter described herein includes methods and systems for providing accidental stack join protection. According to one embodiment, a method includes connecting stacking ports of a first switch that is a member of a first stack and a second switch that is a member of a second stack and thereby joining the first and second stacks. The configurations of the first stack and of the second stack are detected and it is determined whether the detected configurations indicate a configuration mismatch between the first and second stacks. In response to determining that the detected configurations relate to a mismatch, the automatic joining of the first and second stacks is inhibited and the first and second stacks are allowed to continue switching traffic with their existing configurations.

摘要： The invention integrates a plurality of separate stack switches into a unified system of switches under a common configuration and management architecture. The switches, preferably stack switches, may be distributed throughout a local area network (LAN) and need not be co-located. One preferred embodiment supports fail-safe operations to minimize the disruption caused when a stack switch becomes inoperative. In another preferred embodiment, the stack switches are enabled with a system-wide address table and quality of service mapping matrix with which each switch can effectively provision system bandwidth.

摘要： Supportably mounted by each chassis (102c, 104c) of a multi-chassis broadcast router (100) are primary router matrix cards (102a, 104a), redundant router matrix cards (102b, 104b) and clock-demanding input and output cards (136-1 through 136-N and 138-1 through 138-M, 142-1 through 142-N and 144-1 through 144-M). A first master clock (134) resides on the primary router matrix card (102a) of a first chassis (102c) while a second master clock (154) resides on the redundant router matrix card (104b) of a second chassis (104c). Each master clock (134, 154) is configured to provide a respective common clock signal to all of the input and output cards (136-1 through 136-N and 138-1 through 138-M, 142-1 through 142-N and 144-1 through 144-M) of the first and second chassis (102c and 104c). Control logic (148, 156) determines whether the first master clock (134) or the second master clock (154) issues the common clock signal.

摘要： A method, a system, and a network entity for performing the switch-over of a protected Label Switched Path (LSP) in (less than) 50 ms. A goal of the preferable arrangement is to move the tasks related to the switch-over away from the CPU to hardware (HW). The ASIC applies a communication protocol to signal a need for a switch-over between two (or several) units without CPU's participation. A unit, for example Sink of protected domain, which has detected a fault, sends a so-called protection message to a protection pair unit of the unit. The protection pair unit interprets the protection message and actives the connection on the protecting unit.

摘要： A network device includes a first switch, a second switch, address resolution logic (ARL), and a CPU. The first and second switch having a groups of ports which are a subset of the plurality of ports and are numbered by a different numbering schemes. The CPU coupled to the first switch and the second switch and configured to control the first switch, the second switch, and the ARL. A first link port of the first group of ports is coupled to a second link port of the second group of ports. The ARL is configured to perform address resolution based on the first and second numbering schemes such that when the first network port is in a first group of ports and the second network port is in a second group of ports, a data packet received at the first network port destined for the second network port is directly routed from the first network port to the second network port.
