Description
Technical field
The present invention relates to field of computer network communication, be meant a kind of on Ethernet switch, realize the having cluster network management system and the method for high reliability and flexibility especially.
Background technology
Clustering, be on the Ethernet switch by with a large amount of access-layer switch that is dispersed in diverse location of the strong switch management of a spot of disposal ability, it can be managed concentratedly a switch group easily.This way to manage can replace having the way to manage of piling up of physical location and physical connection restriction, and can make the switch of various different manufacturers different models form cluster.The main purpose of cluster management is the centralized management problem that solves a large amount of network equipments that disperse.Cluster management has the following advantages:
1, saves public network IP address;
2, simplify configuration management tasks: administrator just specifies on an equipment, dispose public network IP address just can be to cluster in all devices manage, be managed for configuration on every equipment and need not to sign in to;
3, can the display network topological structure, help monitoring and debugging network;
4, can carry out software upgrading and configuration to multiple devices simultaneously, and not be subjected to the restriction of network topology and distance.
The process of setting up of cluster:
1, cluster management is realized by cluster protocol, cluster protocol has three kinds of type of messages, is respectively DP (Discovery Packet, Topology Discovery message), DR (Di scovery Reply, the back message using of Topology Discovery message), CP (Command Packet, cluster configuration message).These three kinds of messages use SNAP (sub network access protocol) agreement to encapsulate.Wherein the purpose mac of DP and DR message (Media Access Control, medium access control) is that the clean culture mac of appointment, the purpose mac of CP message are the cpu mac of purpose switch.
2, generally have three kinds of roles in a cluster, be respectively: command switch, member switch and candidate switch.Wherein, command switch is the management interface of whole cluster, is responsible for member switch is managed for configuration; Member switch is to add cluster, by command switch to its switch that manages; Candidate switch is the switch with clustering functionality that does not add cluster.Fig. 1 for example understands the cluster management structure chart with above-mentioned three kinds of roles.
3, cluster is configured and manages by the equipment of above three kinds of protocol massages to cluster inside.Its course of work comprises the discovery of topology, the foundation and the maintenance of cluster.Concrete running is as follows:
A), the periodic broadcasting DP message in starting the VLAN of cluster of command switch at first, receive that the switch of DP message is responded the DR message on the one hand, in addition, other port relaying DP message in it receives the VLAN at port place of DP message.Wherein can carry some topology informations of switch in the DR message, such as mac, hostname, portspeed etc.Command switch is set up topological relation after receiving the DR message, and other switch becomes its candidate switch.
B), command switch can be manually or is passed through automatically to send the CP message to certain candidate switch, ask it to add cluster, candidate switch is received loopback confirmation message behind the CP message that adds cluster, after command switch is received confirmation message, adds it and is member switch.Command switch can distribute the inner private IP address of using of a cluster for each member switch from the IP pond, and sets up the TCP connection with it, is that it distributes a cluster member sequence number member id simultaneously.
C), command switch can come member switch is configured synchronously by the CP message.
Administering and maintaining of cluster:
Cluster administer and maintain the maintenance that mainly comprises the cluster protocol state machine, guarantee that the state of cluster runs well, such as the correct adding and the deletion of cluster member, the synchronous renewal of configuration, the configuration management of cluster member.
At first, after setting up, cluster needs to keep the cluster relation between command switch and the member switch, general producer can send a kind of independently heartbeat message at set intervals after cluster is set up, can not receive heartbeat packet or command switch continuously several times at member switch and can not receive heartbeat and respond the situation next part group relation of bag and can finish, can rebulid the cluster relation after waiting the cluster state normal.
Secondly, command switch can add as member switch with candidate switch or member switch is deleted from cluster by sending the CP message, becomes candidate switch, also can restart certain member switch.In addition, when command switch has been revised some configurations of cluster, send at interval such as heartbeat packet, the heartbeat packet maximum is lost number of times, can be amended configuration synchronization to each member switch.
At last, the most important thing is after cluster is set up that the keeper can manage by the member of variety of way to cluster, general producer all can provide the access mode of SNMP, Telnet, HTTP.These modes generally all are to set up TCP or UDP passage by the private ip of cluster inside to finish visit to member switch.When from the member switch of external reference cluster inside, command switch generally all can provide the IP address and the port numbers of a public network, the public network IP address of visit order switch at first during external reference, the mode of different visit member switch is provided according to different should being used for then, with the telnet access is example, when the user need login the Telnet of member switch, because member switch is a private net address, can't directly login, need at first sign in on the Telnet of command switch, on the Telnet of command switch by specific order, start a TelnetClient, sign in on the member switch by private net address, then member switch is operated.
The access mode of SNMP is that the SNMP client is carried out route by publicly-owned IP address and command switch, carry out route by privately owned IP address between command switch and the member switch, by processing and the forwarding of command switch, finish the communication between SNMP client and the member switch to the SNMP message.
Fig. 2 understands that for example the SNMP message is by the message forwarding process of the inner UDP packaged type visit of cluster member switch in the prior art.Its concrete steps are: client structure SNMP proxy requests message, and this request message sent to command switch, wherein the form of the community field in the proxy requests message need comprise the required additional information of forwarding, to reflect the member switch that will visit, such as can behind the community of command switch, adding “ @SW＜member id〉" to reflect the member switch that will visit.After command switch is received request message, according to the community field information in the request message, obtain the member switch information that to visit, construct new SNMP request message, promptly remove the “ @SW＜member id behind the community〉", then by using the UDP passage of cluster privately owned address foundation, it is forwarded on the member switch, member switch returns the SNMP back message using along original route to command switch, command switch recovers the raw information in the back message using, and it is forwarded on the corresponding SNMP client.
The access mode of HTTP and the access mode of SNMP are similar, client need add in URL when visiting certain member switch by command switch transmits required additional information, such as can the public network IP address back in URL adding＜member id 〉, to reflect the member switch that to visit, after command switch is received the HTTP request message, by among the URL＜member id obtain the member switch that will visit, be established to the HTTP connection of member switch then by the cluster private ip, remove among the URL＜member id be transmitted to corresponding member switch, member switch is to command switch loopback HTTP back message using, command switch is received behind the back message using interpolation＜memberid in URL〉information, it is forwarded on the clients corresponding.
By said method, can on switch, realize clustering functionality, and the mode of abundant visit cluster member can be provided that above-mentioned functions is also finished in the realization of general producer substantially.But there are some serious deficiencies in this method, and it mainly shows following 2 points:
1, not backup of command switch: for a cluster, command switch is the inlet of a unique visit cluster, in case command switch goes wrong, the equipment in the whole cluster can't be visited;
2, the packaged type of cluster internal control message is more single: cluster management protocol mainly is that a large amount of low and middle-end switches is managed concentratedly, the resource-constrained of low and middle-end switch, because the restriction of its memory space and disposal ability, a lot of low and middle-end switches are just finished simple two layers and are transmitted control, have management functions such as simple VLAN, ICP/IP protocol is not supported yet.This situation, above-mentioned implementation can't be finished the operation that modes such as SNMP are visited the member.
Summary of the invention
The objective of the invention is to overcome the deficiency in the background technology and provide one on Ethernet switch, to realize having the cluster network management system and the method for high reliability and flexibility.The present invention is that a kind of encapsulation realizes the high reliability of cluster and the method for flexibility by the backup command switch with to the Ethernet of cluster internal control message.
