<h3 id="list_protocols">list_protocols</h3>

**Method signature**:
[driver.list_protocols()](/apidocs/current/libcloud.loadbalancer.base.Driver.html#list_protocols)  
**Description**: Return a list of protocols which can be load balanced 
and are supported by the provider.  

<h3 id="list_balancers">list_balancers</h3>

**Method signature**:
[driver.list_balancers()](/apidocs/current/libcloud.loadbalancer.base.Driver.html#list_balancers)  
**Description**: Return a list of the available LoadBalancer instances.  


<h3 id="balancer_list_members">balancer_list_members</h3>

**Method signature**:
[driver.balancer_list_members(balancer)](/apidocs/current/libcloud.loadbalancer.base.Driver.html#balancer_list_members),
[balancer.list_members()](/apidocs/current/libcloud.loadbalancer.base.LoadBalancer.html#list_members)  
**Description**: Return a list of the Member objects which are attached to this
load balancer.

<h3 id="get_balancer">get_balancer</h3>

**Method signature**:
[driver.get_balancer(balancer_id)](/apidocs/current/libcloud.loadbalancer.base.Driver.html#get_balancer)  
**Description**: Return a LoadBalancer instance. This method is useful if you
know the load balancer id and want to obtain a reference to perform operations with
it.

<h3 id="create_balancer">create_balancer</h3>

**Method signature**:
[driver.create_balancer(name, port, protocol, algorithm, members)](/apidocs/current/libcloud.loadbalancer.base.Driver.html#create_balancer)  
**Description**: Create a new load balancer and optionally attach initial
members to it.

<h3 id="destroy_balancer">destroy_balancer</h3>

**Method signature**:
[driver.destroy_balancer(balancer)](/apidocs/current/libcloud.loadbalancer.base.Driver.html#destroy_balancer),
[balancer.destroy()](/apidocs/current/libcloud.loadbalancer.base.LoadBalancer.html#destroy)  
**Description**: Destroy a load balancer.

<h3 id="balancer_attach_member">balancer_attach_member</h3>

**Method signature**:
[driver.balancer_attach_member(balancer, member)](/apidocs/current/libcloud.loadbalancer.base.Driver.html#balancer_attach_member),
[balancer.attach_member(member)](/apidocs/current/libcloud.loadbalancer.base.LoadBalancer.html#attach_member)  
**Description**: Add a new member to the load balancer.  

<h3 id="balancer_attach_compute_node">balancer_attach_compute_node</h3>

**Method signature**:
[driver.balancer_attach_compute_node(balancer, node)](/apidocs/current/libcloud.loadbalancer.base.Driver.html#balancer_attach_compute_node),
[balancer.attach_compute_node(node)](/apidocs/current/libcloud.loadbalancer.base.LoadBalancer.html#attach_compute_node)  
**Description**: Add a new member to the load balancer. This method expected a
Node object from the compute API as an argument. It automatically reads Node's
first public IP address before adding a new member.

<h3 id="balancer_detach_member">balancer_detach_member</h3>

**Method signature**:
[driver.balancer_detach_member(balancer, member)](/apidocs/current/libcloud.loadbalancer.base.Driver.html#balancer_detach_member),
[balancer.detach_member(member)](/apidocs/current/libcloud.loadbalancer.base.LoadBalancer.html#detach_member)  
**Description**: Remove a member from the load balancer.
