A method for maintaining packet's source network identification information while aggregating packets from a plurality of networks is provided. An ingress packet is processed to extract a plurality of packet header fields and port identifier. A first hash index is generated by hashing information associated with the plurality of packet header fields. The extracted port identifier is stored in a hash table using the generated first hash index. The ingress packet is forwarded to one or more inline tool devices. An egress packet received from the one or more inline tools is processed to extract the plurality of packet header fields. A second hash index is generated by hashing information associated with the plurality of packet header fields. The port identifier is retrieved from the hash table based on the generated second hash index. The egress packet is transmitted to a switching device based on the retrieved port identifier.

AIA enhancements to support lag networks

Techniques for compressing data in a wireless network are provided. Data may be in the form of data packets that have one or more headers and a payload. One or more compression initiation criteria are used to determine whether to compress all data or certain data. Different data may be associated with different classes of service. Compression initiation criteria for data that belongs to one class of service may be different than compression initiation criteria for data that belongs to another class of service. Compression initiation criteria for data may be different than one or more compression halting criteria that are used to determine whether to cease compressing data. One type of compression involves use of synchronized history buffers. A wireless receiver may communicate with a wireless transmitter that an error is detected and that the history buffers of the wireless transmitter should be flushed or cleared.
