Description

Ring protection processing method
Technical field
The present invention relates to a kind of in the automatic resist technology of Ethernet ring protection processing method.
Background technology
The ethernet ring network automatic protective system is linked to each other by a plurality of nodes and constitutes ring; wherein; can define a plurality of territories on the ring; comprise host node and transmission node in the territory; and the protection of one group of this territory be used for professional VLAN (Virtual Local AreaNetwork abbreviates VLAN as) that user data transmits and the control VLAN that is used for the protocol massages forwarding.For a special domain, protected service VLAN is called the protection service VLAN, and the port on two rings of host node is defined as master port respectively and from port.Host node sends link health detection frame from master port, is receiving link health detection frame from port if link is intact.When link is intact; host node blocks the protection service VLAN forwarding capability from port; when link occurs fault; relieving is from the protection service VLAN forwarding capability of port; and host node sends the Link State notification frame when link switchover; transmission node upgrades medium access control (media access control the abbreviates MAC as) address table of ring upper port after receiving the Link State notification frame, the user data in the protection service VLAN is according to new path transmission.The ethernet ring network automatic protective system has guaranteed that the protection service VLAN can not form loop, has prevented because " broadcast storm " that loop causes.When on a physical rings, only having an independent territory; the link switchover convergence time of ethernet ring network automatic protective system can reach in 50 milliseconds; but under the single domain situation, the protection service VLAN data can not by host node from port transmission, greatly wasted link bandwidth.When having a plurality of territory on the physical link; the protection service VLAN data of same area can be by different path transmission; made full use of link bandwidth; but the link switchover convergence time of ethernet ring network automatic protective system is the stack of a plurality of territory link switchover convergence times; when the ring co-domain during many or loop more complicated; usually can reach more than the hundreds of millisecond; make and to satisfy next-generation communication network (Next generation network well; abbreviate NGN as); Web TVs (Internet protocol television abbreviates IPTV as) etc. are professional to the network high reliability; the requirement of high real-time.
In order to make full use of link bandwidth, in the actual networking of ethernet ring network automatic protective system, usually the service VLAN on the same physical rings is divided into many group protection service VLAN, every group of protection service VLAN protected with different ethernet ring network territories.
Fig. 1 is the topological structure of ethernet ring network; wherein; telephone net node S1, S2, S3, S4 have formed ethernet ring network; a plurality of service VLAN on each node, have been disposed; if there is not the ethernet ring network automatic protective system; these VLAN will form loop so, cause " broadcast storm " thus cause network unavailable.
These service VLAN are divided into two groups, protect by territory 1 and territory 2 respectively.In territory 1, node S2 is a host node, and the master port of host node is a port one, is port 2 from port, and node S1, S3, S4 are transmission nodes; In territory 2, node S2 is a host node, and the master port of host node is a port 2, is port one from port, and node S1, S3, S4 are transmission nodes.
When link was intact, the protection service VLAN data forwarding function of the port 2 of node S2 had been blocked in territory 1, and the protection service VLAN in territory 1 can not be by port 2 transmission of S2.Though territory 1 has been avoided forming loop in the protection service VLAN by the port 2 that blocks node S2; but when there not being territory 2, that is, and when only having a territory on this physics loop; do not have business datum on the link between node S2 and the S4, making has greatly wasted link circuit resource.In order to make full use of link circuit resource, dispose the ethernet ring network multiple domain in actual applications usually.For territory 2; when link is intact; the protection service VLAN data forwarding function of blocking the port one of node S2; the protection service VLAN in territory 2 can not avoid forming loop in the protection service VLAN, and the protection service VLAN data in territory 2 can be by the port 2 of node S2 by the port one transmission of S2; promptly; on the link between node S2 and the S4, transmit, realized load balancing, made full use of link circuit resource.
When link occurs fault; for example; during link occurs fault among Fig. 1 between node S3 and the S4; the ethernet ring network automatic protective system detects the laggard line link troubleshooting of link failure; host node is decontroled the protection service VLAN forwarding capability from port; go up transmission link failure state notifying frame to ring; and the mac address table of renewal ring upper port; transmission node is after receiving the link failure state notifying frame that host node sends; upgrade the mac address table of ring upper port; the protection service VLAN data can by host node from port transmission, having guaranteed has a logic approach that can be communicated with between two nodes.During link failure; host node still sends link health detection frame from master port; if receiving link health detection frame from port; then think link-recovery; host node blocks the protection service VLAN forwarding capability from port; go up transmission link-recovery state notifying frame to ring; and the mac address table of renewal ring upper port; transmission node is after receiving the recovering state state notifying frame that host node sends; upgrade the mac address table of ring upper port; the data of protection service VLAN can be by original faulty link transmission; can not by host node from port transmission; guaranteed to have only a logic approach that can be communicated with between two nodes, can not form and open circuit or loop.
During ethernet ring network automatic protective system handle link fault, the data of protection service VLAN can not be transmitted by faulty link, only at the protection service VLAN forwarding capability of host node relieving from port, and ring is gone up after the node updates ring upper port mac address table, the data of protection service VLAN could be by the transmitting from port of host node, and the host node in the territory is decontroled and gone up node updates ring upper port mac address table from the protection service VLAN forwarding capability of port and ring and can be time sequencing arbitrarily; When ethernet ring network automatic protective system handle link is recovered; there is the transmission path of two connections physically in the data of protection service VLAN; at the protection service VLAN forwarding capability of host node obstruction from port; and ring is gone up after the node updates ring upper port mac address table; the data of protection service VLAN can not form loop; therefore; be necessary for the protection service VLAN forwarding capability of first host node obstruction from port; ring is gone up node updates ring upper port mac address table then, and both time sequencings can not be put upside down.
In addition, encircle in the networking at single domain more, a link switchover meeting produces a plurality of Link State notification frame, and node needs to upgrade the port mac address table after receiving the Link State notification frame at every turn on the ring, and a link switchover meeting causes ring to go up node and repeatedly repeats hardware operation is upgraded the port mac address table.
Because the restriction of hardware handles ability, the mac address table that upgrades port is more consuming time, and the MAC Address of only upgrading some VLAN on the port is not saved time than upgrading on this port all address tables.When Ethernet ring protection system was carried out link switchover, node repeatedly repeated hardware operation is upgraded the mac address table of port on the ring, accumulated consuming time very longly, sometimes even reach the hundreds of millisecond, was unfavorable for the quick switching of Ring protection system.
Therefore, need a kind of Ethernet ring protection method that can restrain fast.

In above-mentioned behaviour's operation, do not carry out hardware operation consuming time; at last; in step 410; the address update mode that the quick timer of node inquires port on ring is that the address is upgraded after the preparing state; if deducting this port address last time, the current time upgrades guard time greater than the address update time; the address update mode that this port then is set is that ready attitude is upgraded in the address; upgrade the mac address table of this port; the address update mode that this port is set is that the address is upgraded and to be finished attitude, and recording address update time.
With reference to Fig. 5, the processing procedure when link failure is eliminated (for example, the link-recovery between node S3 and the S4) is described.
In step 501, when the host node S2 in the territory 1 receives from link health detection frame that port one sends from port 2, the territory 1 protection service VLAN forwarding capability of port blocked 2 is gone up transmission link-recovery state notifying frame to ring, and the address update mode of port 2 is set to the address and upgrades preparing state;
In step 502, when the host node S2 in the territory 2 receives from link health detection frame that port 2 sends from port one, the territory 2 protection service VLAN forwarding capabilitys of port blocked 1 are gone up transmission link-recovery state notifying frame to ring, and the address update mode of port one is set to the address and upgrades preparing state;
Then, in step 503, after transmission node in the territory 1 is received the link-recovery state notifying frame of host node transmission, node S3 decontrols the protection service VLAN forwarding capability in the territory 1 of port one, node S4 decontrols the protection service VLAN forwarding capability in the territory 1 of port one, and the address update mode of each transmission node ring upper port is set to the address and upgrades preparing state;
In step 504, after transmission node in the territory 2 is received the link-recovery state notifying frame of host node transmission, node S3 decontrols the protection service VLAN forwarding capability in the territory 2 of port one, node S4 decontrols the protection service VLAN forwarding capability in the territory 2 of port one, and the address update mode of each transmission node ring upper port is set to the address and upgrades preparing state;
In aforesaid operations, there is not hardware operation consuming time, at last, in step 505, the address update mode that the quick timer of node inquires port on ring is that the address is upgraded after the preparing state, the address update mode that this port is set is that ready attitude is upgraded in the address, upgrade the mac address table of this port, the address update mode that this port is set is that the address is upgraded and to be finished attitude, and recording address update time.
For example, in certain Ethernet ring network system, used method of the present invention.Wherein, 15 territories have been disposed on the ring; when link occurs fault; on each node hardware operation being upgraded in the address of ring upper port is to carry out after Ethernet ring protection system has been finished operation not consuming time such as other various software records; and port address renewal operation has only been carried out once rather than 15 times; upgrade action needs and expend the hundreds of millisecond and carry out 15 port addresss, but use not increasing and strengthen of link switchover convergence time after the inventive method with the territory.During link switchover, business datum is stable, and node is few to the hardware operation number of times, and probability of failure is low, and convergence time is in 50 milliseconds.
In addition, the present invention not only can be applied to multiple domain, also can be applied in the single domain.
When looped network is made up of a plurality of tangent rings, can carries out level to ring and divide, when node is received the link switchover notice of low level node transmission on the high-rise secondary ring, need to upgrade ring upper port mac address table.But when the low level link switched, high-level node can be received the link switchover notice that a plurality of low level nodes are sent, and causes repeatedly carrying out hardware operation and upgrades the port mac address table, and was consuming time very long.After using the inventive method, node is when upgrading the port mac address table, just having write down the port application state is that port address upgrades preparing state, there is not real operational hardware, it is just to carry out hardware operation renewal port address MAC table after preparing state is upgraded in the address that quick timer detects the port address update mode, making the hardware address that repeats upgrade operation has only carried out once, during link switchover, business datum is stable, node is few to the hardware operation number of times, probability of failure is low, and convergence time is fast.
In sum; by technique scheme of the present invention; link switchover adaptive updates mac address table has been proposed; the fast processing ethernet ring network is the method for protection automatically; notions such as port address update mode have been introduced; when carrying out link switchover, Ethernet ring protection system do not repeat to upgrade the port mac address table; avoided hardware operation consuming time; the processing speed and the stability of Ethernet ring protection system have greatly been improved; especially the link switchover convergence time of Ethernet ring protection system can not strengthen when the number of same physical rings co-domain increases, and satisfies the requirement of high real-time business to Ring protection system when utilizing multiple domain to carry out balancing link load.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
