Embodiment 1

[0033] As shown in Fig. 2, the present invention is the original main line between router and switch, adds a backup line, and installs a bridging mode network acceleration device FB2 (standby) in this backup line, and the bridging network in the backup line The configuration of the acceleration device and the bridging network acceleration device of the main line can be different. Since the bridge mode network acceleration device FB1 (activation) and the bridge mode network acceleration device FB2 (standby) in the standby line perform hot backup monitoring, when the two paths are normal, the network interface of the bridge network acceleration device FB1 (activation) allows The packet passes, except for the hot backup monitoring communication packet between the two devices, the network interface of the bridging network acceleration device FB2 (standby) blocks other packets to ensure that the backup line from point C to point D is unreachable, and that there is no communication b...

Embodiment 2

[0049] Add a connection line E between the bridged network acceleration devices FB1 and FB2 that realize dual-machine hot backup, and the active state device sends a status briefing to the standby state device on this connection line E, as shown in Figure 6, the bridged network acceleration When the device FB1 is activated, it will check the network status in two directions:

[0050] 1. Send an ICMP request to the uplink router or uplink switch or other IP devices on the uplink or external network websites or other IP devices on the external network on the network port of the uplink remote line A to determine the status of the uplink.

[0051] 1.1 If the ICMP response from the upstream device is received within the specified time, FB1 remains active.

[0052] 1.2 If there is no ICMP response from the uplink device within the specified time, FB1 determines that there is a fault between the uplink remote line A and the uplink device (as shown in Figure 7), and immediately connec...

Embodiment 3

[0070] In Embodiment 3, the 802.3ad (LACP) multi-link aggregation (accompanying drawing 10) must be started on the upstream router or the upstream switch and the downstream router or the downstream switch, and when the bridging network acceleration device is connected, there is a connection line E between FB1 and FB2 , FB1 and FB2 send a status briefing on the E line, and the E line is also a data backup line. The two physical devices FB1 and FB2 will form a virtual bridge network acceleration device, and the virtual bridge network acceleration device will start 802.3ad (LACP) multi-chain The road aggregation protocol is connected to the upstream device and the downstream device (Fig. 11), and the traffic can be accelerated through FB1 or FB2 at the same time (Fig. 12).

[0071] 1. When the uplink A fails:

[0072] 1.1 FB1 detects the failure of the uplink A network port, FB1 sends an uplink path failure report to FB2, and changes the traffic channel of the uplink A network po...

Abstract

The invention provides a twin engined warm back-up method of a bridge network accelerating device, wherein a first bridge network accelerating device transmits the ICMP request to a router on the net mouth of the upper connecting far end circuit; the first bridge network accelerating device informs the second bridge network accelerating device of replacing from the armed state to the activation state if not obtaining the ICMP response in the given time; meanwhile, the first bridge network accelerating device is replaced from the activation state to the failure armed state; the first bridge network accelerating device transmits the state briefing on the net mouth of the lower connecting near end circuit to the second bridge network accelerating device through the network; if the second bridge network accelerating device does not receive the state briefing of the first bridge network accelerating device in the given time, the second bridge network accelerating device is replaced from the armed state to the activation state.

Description

technical field [0001] The invention relates to the field of network hot backup, in particular to the dual-machine hot backup of bridging network acceleration devices. Background technique [0002] Existing network acceleration devices or proxy devices operate on a three-layer network (Explicit mode / Transparent mode / IPaddress Layer / Layer 3), and there are few network acceleration devices that support bridge mode (Bridged mode / Mac address Layer / Layer 2) . As shown in Figure 1, the existing bridged mode (Bridged Mode) network acceleration devices are generally located between routers and switches, and in the network structure, from routers to switches to users, they are all in the same broadcast domain, that is, they are all in the same broadcast domain. within the same IP network segment. For example, when the bridge mode network acceleration device fails in the network path, it will cause a single point of failure, resulting in network truncation, and users cannot connect ...
