### 4.5 RDMA Provider Implementations

#### 4.5.1 DiSNI Provider (InfiniBand/RoCE)
```java
package jcifs.internal.smb2.rdma.disni;

import com.ibm.disni.*;
import com.ibm.disni.verbs.*;

public class DisniRdmaProvider implements RdmaProvider {
    private RdmaActiveEndpointGroup<DisniRdmaEndpoint> endpointGroup;

        PropertyConfiguration config = new PropertyConfiguration(props);

        assertTrue(config.isUseRDMA(), "RDMA should be enabled");
        assertEquals("disni", config.getRdmaProvider(), "Provider should be disni");
        assertEquals(16384, config.getRdmaReadWriteThreshold(), "Threshold should be 16KB");
        assertEquals(131072, config.getRdmaMaxSendSize(), "Max send size should be 128KB");

     * @param preference provider preference ("auto", "disni", "tcp", etc.)
     * @return best available RDMA provider, or null if none available
     */

        if ("auto".equalsIgnoreCase(preference)) {

        case "disni":

├── RdmaChannel.java             - RDMA channel operations
└── RdmaProvider.java            - RDMA provider abstraction
```

#### 5.2 Implementation Tasks
- [ ] Research Java RDMA libraries (e.g., DiSNI, JXIO)
- [ ] Implement RDMA capability detection
- [ ] Create RDMA negotiation context
- [ ] Implement RDMA transport layer
- [ ] Add RDMA buffer registration
- [ ] Create RDMA read/write operations

Mais au moment où Python compare le premier `j` de `johndoe` au premier `s` de `stanleyjobson`, il retournera `False`, car il sait déjà que ces deux chaînes ne sont pas identiques, en se disant qu'« il n'est pas nécessaire de gaspiller plus de calcul pour comparer le reste des lettres ». Et votre application dira « Nom d'utilisateur ou mot de passe incorrect ».

### Vérifier le code { #check-the-code }

* Vérifiez et lisez le code, voyez s'il a du sens, **exécutez‑le localement** et voyez s'il résout effectivement le problème.

* Ensuite, **commentez** en disant que vous l'avez fait, c'est ainsi que je saurai que vous l'avez vraiment vérifié.
