TCP Performance in Case of Bi-Directional Packet Loss
White Papers However, the existing modeling approaches unanimously assume that packet loss only occurs for data packets (i.e.for packets from the server to the client), whereas in reality the packets in the direction from the client to the server (e.g.

IM-OM Matching Packet Dispatching Scheme for MSM Clos-Network Switches
White Papers Current packet dispatching algorithms for next generation network nodes (switches/routers), in the majority of cases, involve the request-grant-accept handshaking scheme with many iterations and the effect of desynchronization of arbitration...
